# Lotus changelog

# UNRELEASED

## ☢️ Upgrade Warnings ☢️

- This Lotus release includes some correctness improvements to the events subsystem, impacting RPC APIs including `GetActorEventsRaw`, `SubscribeActorEventsRaw`, `eth_getLogs` and the `eth` filter APIs. Part of these improvements involve an events database migration that may take some time to complete on nodes with extensive event databases. See [filecoin-project/lotus#12080](https://github.com/filecoin-project/lotus/pull/12080) for details.

## New features

- feat: Add trace transaction API supporting RPC method `trace_transaction` ([filecoin-project/lotus#12068](https://github.com/filecoin-project/lotus/pull/12068))

## Improvements

# v1.28.0-rc2 / 2024-07-04

This is the second release candidate of the upcoming MANDATORY Lotus v1.28.0 release, which will deliver the Filecoin network version 23, codenamed Waffle 🧇.

**This release candidate sets the calibration network to upgrade at epoch 1779094, corresponding to 2024-07-11T12:00:00Z.** This release does NOT set the mainnet upgrade epoch yet, in which will be updated in the final release.

☢️ Upgrade Warnings ☢️

If you are running the `v1.26.0` or an earlier version of Lotus, please go through the `Upgrade Warnings` section for the `v1.27.*` releases, before upgrading to this RC.

- This upgrade includes an additional migration to the events database. Node operators running Lotus with events turned on (off by default) may experience some delay in initial start-up of Lotus as a minor database migration takes place. See [filecoin-project/lotus#12080](https://github.com/filecoin-project/lotus/pull/12080) for full details.

## The Filecoin network version 23 delivers the following FIPs:

- [FIP-0065: Ignore built-in market locked balance in circulating supply calculation](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0065.md)
- [FIP-0079: Add BLS Aggregate Signatures to FVM](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0079.md)
- [FIP-0084: Remove Storage Miner Actor Method ProveCommitSectors](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0084.md)
- [FIP-0085: Convert f090 Mining Reserve Actor to Keyless Account Actor](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0085.md)
- [FIP-0091: Add support for legacy Ethereum transactions](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0091.md)
- [FIP-0092: NI-PoRep](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0092.md)
- [FIP-0086: Fast Finality Soft Launch](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0086.md)

Note that we are only doing a "soft launch"/"passive testing" for F3 (Fast Finality) i.e. FIP-0086 in NV23. Please see [this doc](https://docs.google.com/document/d/14hMFN95_AsByBh7iMc4r_czUgg8tfjHQ1gTsmmHZ8jI/edit#heading=h.dhzqs3lisv24) for more details.

## Migration

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the network upgrade. The migration for the NV23 upgrade is expected to be light with no heavy pre-migrations, here are some expected timings and resource consumption numbers:

- Pre-Migration is expected to take less then 1 minute
- The migration is expected to take less then 30 seconds on a node with a NVMe-drive and a newer CPU. For nodes running on slower disks/CPU, it is still expected to take less then 1 minute.

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), we recommend skipping the pre-migration and run the non-cached migration (i.e., just running the migration at the network upgrade epoch), and schedule for some additional downtime. Operators of such nodes can read the [How to disable premigration in network upgrade tutorial.](https://lotus.filecoin.io/kb/disable-premigration/)

# v1.27.1 / 2024-06-24

This release, v1.27.1, is an OPTIONAL lotus release. It is HIGHLY RECOMMENDED for node operators that are building Filecoin index off lotus!

## ☢️ Upgrade Warnings ☢️

- This Lotus release completely removes the Legacy Lotus/Lotus-Miner Markets sub-system from the codebase, which was announced to reach EOL on January 31, 2023.
- The **Curio Storage** software, designed to simplify the setup and operation of storage providers, has moved to their own Github-repository: https://github.com/filecoin-project/curio.
- The events subsystem includes some minor correctness fixes and performance improvements. Nodes operators running Lotus with events turned on (off by default) may experience some delay in initial start-up as a minor database migration takes place and the write-ahead log is compacted. See [filecoin-project/lotus#11952](https://github.com/filecoin-project/lotus/pull/11952) and [filecoin-project/lotus#12090](https://github.com/filecoin-project/lotus/pull/12090) for full details.

### JSON-RPC 2.0 Specification Conformance

The JSON-RPC 2.0 specification requires that a `"result"` property be present in the case of no error from an API call. This release ensures that all API calls that return a result have a `"result"` property in the response. This is a behaviour change over Lotus v1.26 and will impact any API call that only has a single error return value, where no error has occurred.

For example, a successful `WalletSetDefault` in v1.26 would return:

```json
{
  "jsonrpc": "2.0",
  "id": 1
}
```

As of this change, in conformance with the JSON-RPC 2.0 specification it will return:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": null
}
```

There is no change in the behaviour when a call returns an error, as the error object will still be present in the response.

# v1.27.0 / 2024-05-27

This is an optional feature release of Lotus. Lotus v1.27.0 includes numerous improvements, bugfixes and enhancements for node operators, RPC- and ETH RPC-providers. This feature release also introduces Curio in a Beta release. Check out the Curio Beta release section for how you can get started with Curio.

## ☢️ Upgrade Warnings ☢️

- This feature release drops the Raft cluster code experiment from the codebase. This Raft cluster never graduated beyond an experiment, had poor UX (e.g. no way to manage a running cluster, so it didn't provide High Availability), and pulled in a lot of heavy dependencies. We keep the multi-node RPC feature, it is not perfect, but it is useful.
- Event Database: Two sequential migrations will adjust indexes without altering data or columns, ensuring minimal invasiveness when upgrading to this release. However, these migrations may be time-consuming for nodes with extensive event databases.

## Indexers, RPC- and ETH RPC-providers improvements

This release includes a lot of improvements and fixes for indexers, RPC- and ETH RPC-providers. Specifically these PRs:

- [Significant performance improvements of eth_getLog](https://github.com/filecoin-project/lotus/pull/11477)
- [Return the correct block gas limit in the EthAP](https://github.com/filecoin-project/lotus/pull/11747)
- [Accept input data in call arguments under field 'input'](https://github.com/filecoin-project/lotus/pull/11505)
- [Length check the array sent to eth_feeHistory RPC](https://github.com/filecoin-project/lotus/pull/11696)
- [ETH subscribe tipsets API should only return tipsets that have been executed](https://github.com/filecoin-project/lotus/pull/11858)
- [Adjust indexes in event index db to match query patterns](https://github.com/filecoin-project/lotus/pull/111934)

## ⭐️ Curio Beta Release  ⭐️

**Curio**, the next generation of Lotus-Miner, also referred to as MinerV2! This release officially transitions Curio into beta and introduces a suite of powerful features designed to enhance your storage operations.

### Highlights

- **Curio as MinerV2**: Embrace the revolutionary upgrade from Lotus-Miner to Curio. This transition is not just a rebranding—it's an upgrade to a more robust, scalable, and user-friendly version.
- **High Availability**: Curio is designed for high availability. You can run multiple instances of Curio nodes to handle similar type of tasks. The distributed scheduler and greedy worker design will ensure that tasks are completed on time despite most partial outages. You can safely update one of your Curio machines without disrupting the operation of the others.
- **Node Heartbeat**: Each Curio node in a cluster must post a heartbeat message every 10 minutes in HarmonyDB updating its status. If a heartbeat is missed, the node is considered lost and all tasks can now be scheduled on remaining nodes.
- **Task Retry**: Each task in Curio has a limit on how many times it should be tried before being declared lost. This ensures that Curio does not keep retrying bad tasks indefinitely. This safeguards against lost computation time and storage.
- **Polling**: Curio avoids overloading nodes with a polling system. Nodes check for tasks they can handle, prioritizing idle nodes for even workload distribution.
- **Simple Configuration Management**: The configuration is stored in the database in the forms of layers. These layers can be stacked on top of each other to create a final configuration. Users can reuse these layers to control the behavior of multiple machines without needing to maintain the configuration of each node. Start the binary with the appropriate flags to connect with YugabyteDB and specify which configuration layers to use to get desired behaviour.

# v1.26.3 / 2024-04-22

**This is a patch release that addresses high memory load concerns for the Lotus daemon in the coming network migration for network version 22, scheduled on epoch `3855360 - 2024-04-24 - 14:00:00Z`.**

If your Lotus daemon is running on a machine with less memory and swap than 160GB, you should upgrade to this patch release to ensure you do not encounter any Out-Of-Memory issues during the pre-migration.

# v1.26.2 / 2024-04-08

**This is a mandatory patch release for the Filecoin network version 22 mainnet upgrade, for all node operators.**

There is an update in the upgrade epoch for nv22, you can read the [full discussion in Slack here.](https://filecoinproject.slack.com/archives/C05P37R9KQD/p1712548103521969)

The new upgrade epoch is scheduled to be on **epoch `3855360 - 2024-04-24 - 14:00:00Z`**. That means:

- **All mainnet node operators that have upgraded to v1.26.x, must upgrade to this patch release before 2024-04-11T14:00:00Z.**
- **All mainnet node operators that are on a version lower the v1.26.x, must upgrade to this patch release before 2024-04-24T14:00:00Z.**

This patch also includes fixes for node operators who want to index builtin-actor events after the nv22 upgrade. Specifically, it ensures the builtin actor event entries are ordered by insertion order when selected ([#11834](https://github.com/filecoin-project/lotus/pull/11834)). It also includes a couple Lotus-Miner patch fixes, ensuring that SnapDeals works properly and are using the new ProveReplicaUpdate3 message after the network version 22 upgrade, ensuring that DDO-sectors has the correct sector expirations, as well as DDO-sector visibility in the `lotus-miner sectors list` cmd.

## Upgrade Warnings

For users currently on a version of Lotus lower than v1.26.0, please note that **this release requires a minimum Go version of v1.21.7 or higher to successfully build Lotus.**

# v1.26.1 / 2024-03-27

***RETRACTED: Due to a change in network version 22 upgrade epoch, Lotus v1.26.1 should not be used prior to the new upgrade epoch. See v1.26.2 release notes above.***

**This is a patch release for the Calibration network user.** The Calibration network is scheduled for an upgrade to include the two additional built-in actor events to ease the transition and observability of DDO for the ecosystem ([#964](https://github.com/filecoin-project/FIPs/pull/964) and [#968](https://github.com/filecoin-project/FIPs/pull/968)).

The agreed-upon epoch between the Filecoin implementer team for the update is `1493854`, corresponding to `2024-04-03T11:00:00Z`. All Calibration network users need to upgrade to this patch release before that.

 **Lotus Mainnet Users**: For users on the Mainnet, the [Lotus v1.26.0](https://github.com/filecoin-project/lotus/releases/tag/v1.26.0) release already includes the aforementioned events in preparation for the Mainnet nv22 upgrade. Therefore, both v1.26.0 and v1.26.1 versions are suitable for use on the Mainnet for the coming network version 22 upgrade.

# v1.26.0 / 2024-03-21

***RETRACTED: Due to a change in network version 22 upgrade epoch, Lotus v1.26.0 should not be used prior to the new upgrade epoch. See v1.26.2 release notes above.***

This is the stable release for the upcoming MANDATORY Filecoin network upgrade v22, codenamed Dragon 🐉, at `epoch 3817920 - 2024-04-11 - 14:00:00Z`

The Filecoin network version 22 delivers the following FIPs:

- [FIP-0063: Switching to new Drand mainnet network](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0063.md)
- [FIP-0074: Remove cron-based automatic deal settlement](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0074.md)
- [FIP-0076: Direct data onboarding](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0076.md)
- [FIP-0083: Add built-in Actor events in the Verified Registry, Miner and Market Actors](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0083.md)

## ☢️ Upgrade Warnings ☢️

## Migration

We are expecting a bit heavier than normal state migration for this upgrade due to the amount of state changes introduced with Direct Data Onboarding.

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 120 epochs before the upgrade. It will take around 10-20 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries

We recommend node operators (who haven't enabled splitstore discard mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

You can test out the migration by running running the [`benchmarking a network migration` tutorial.](https://lotus.filecoin.io/kb/test-migration/)

For certain node operators, such as full archival nodes or systems that need to keep large amounts of state (RPC providers), completing the pre-migration in time before the network upgrade might not be achievable. For those node operators, it is recommended to skip the pre-migration and run the non-cached migration (i.e., just running the migration at the exact upgrade epoch), and schedule for some downtime during the upgrade epoch. Operators of such nodes can read the [`How to disable premigration in network upgrade` tutorial.](https://lotus.filecoin.io/kb/disable-premigration/)

- feat: sealing: Support nv22 DDO features in the sealing pipeline (#11226) ([filecoin-project/lotus#11226](https://github.com/filecoin-project/lotus/pull/11226))
- feat: implement FIP-0063 ([filecoin-project/lotus#11572](https://github.com/filecoin-project/lotus/pull/11572))
- feat: events: Add Lotus APIs to consume smart contract and built-in actor events ([filecoin-project/lotus#11618](https://github.com/filecoin-project/lotus/pull/11618))

### Tracing API

Replace the `CodeCid` field in the message trace (added in 1.23.4) with an `InvokedActor` field.

**Before:**

```javascript
{
    "Msg": {
        "From": ...,
        "To": ...,
        ...
        "CodeCid": ... // The actor's code CID.
    }
    "MsgRct": ...,
    "GasCharges": [],
    "Subcalls": [],
}
```

**After:**

```javascript
{
    "Msg": {
        "From": ...,
        "To": ...
    }
    "InvokedActor": {         // The invoked actor (ommitted if the actor wasn't invoked).
        "Id": 1234,           // The ID of the actor.
        "State": {            // The actor's state object (may change between network versions).
           "Code": ...,       // The actor's code CID.
           "Head": ...,       // The actor's state-root (when invoked).
           "CallSeqNum": ..., // The actor's nonce.
           "Balance": ...,    // The actor's balance (when invoked).
           "Address": ...,    // Delegated address (FEVM only).
        }
    }
    "MsgRct": ...,
    "GasCharges": [],
    "Subcalls": [],
}
```

This means the trace now contains an accurate "snapshot" of the actor at the time of the call, information that may not be present in the final state-tree (e.g., due to reverts). This will hopefully improve the performance and accuracy of indexing services.

### Ethereum Tracing API (`trace_block` and `trace_replayBlockTransactions`)

For those with the Ethereum JSON-RPC API enabled, the experimental Ethereum Tracing API has been improved significantly and should be considered "functional". However, it's still new and should be tested extensively before relying on it. This API translates FVM traces to Ethereum-style traces, implementing the OpenEthereum `trace_block` and `trace_replayBlockTransactions` APIs.

This release fixes numerous bugs with this API and now ABI-encodes non-EVM inputs/outputs as if they were explicit EVM calls to [`handle_filecoin_method`][handlefilecoinmethod] for better block explorer compatibility.

However, there are some _significant_ limitations:

1. The Geth APIs are not implemented, only the OpenEthereum (Erigon, etc.) APIs.
2. Block rewards are not (yet) included in the trace.
3. Selfdestruct operations are not included in the trace.
4. EVM smart contract "create" events always specify `0xfe` as the "code" for newly created EVM smart contracts.

Additionally, Filecoin is not Ethereum no matter how much we try to provide API/tooling compatibility. This API attempts to translate Filecoin semantics into Ethereum semantics as accurately as possible, but it's hardly the best source of data unless you _need_ Filecoin to look like an Ethereum compatible chain. If you're trying to build a new integration with Filecoin, please use the native `StateCompute` method instead.

[handlefilecoinmethod]: https://fips.filecoin.io/FIPS/fip-0054.html#handlefilecoinmethod-general-handler-for-method-numbers--1024

### GetActorEventsRaw and SubscribeActorEventsRaw

[FIP-0049](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0049.md) introduced _Actor Events_ that can be emitted by user programmed actors. [FIP-0083](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0083.md) introduces new events emitted by the builtin Verified Registry, Miner and Market Actors. These new events for builtin actors are being activated with network version 22 to coincide with _Direct Data Onboarding_ as defined in [FIP-0076](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0076.md) which introduces additional flexibility for data onboarding. Sector, Deal and DataCap lifecycles can be tracked with these events, providing visibility and options for programmatic responses to changes in state.

Actor events are available on message receipts, but can now be retrieved from a node using the new `GetActorEventsRaw` and `SubscribeActorEventsRaw` methods. These methods allow for querying and subscribing to actor events, respectively. They depend on the Lotus node both collecting events (with `Fevm.Events.RealTimeFilterAPI` and `Fevm.Events.HistoricFilterAPI`) and being enabled with the new configuration option `Events.EnableActorEventsAPI`. Note that a Lotus node can only respond to requests for historic events that it retains in its event store.

Both `GetActorEventsRaw` and `SubscribeActorEventsRaw` take a filter parameter which can optionally filter events on:

* `Addresses` of the actor(s) emitting the event
* Specific `Fields` within the event
* `FromHeight` and `ToHeight` to filter events by block height
* `TipSetKey` to restrict events contained within a specific tipset

`GetActorEventsRaw` provides a one-time query for actor events, while `SubscribeActorEventsRaw` provides a long-lived connection (via websockets) to the Lotus node, allowing for real-time updates on actor events. The subscription can be cancelled by the client at any time.

A future Lotus release may include `GetActorEvents` and `SubscribeActorEvents` methods which will provide a more user-friendly interface to actor events, including deserialization of event data.

### Events Configuration Changes

All configuration options previously under `Fevm.Events` are now in the top-level `Events` section along with the new `Events.EnableActorEventsAPI` option mentioned above. If you have non-default options in `[Events]` under `[Fevm]` in your configuration file, please move them to the top-level `[Events]`.

While `Fevm.Events.*` options are deprecated and replaced by `Events.*`, any existing custom values will be respected if their new form isn't set, but a warning will be printed to standard error upon startup. Support for these deprecated options will be removed in a future Lotus release, so please migrate your configuration promptly.

### GetAllClaims and GetAllAlocations

Additionally the methods `GetAllAllocations` and `GetAllClaims` has been added to the Lotus API. These methods lists all the available allocations and claims available in the actor state.

### Lotus CLI

The `filplus` commands used for listing allocations and claims have been updated. If no argument is provided to the either command, they will list out all the allocations and claims in the verified registry actor.
The output list columns have been modified to `AllocationID` and `ClaimID` instead of ID. 

```shell
lotus filplus list-allocations --help
NAME:
   lotus filplus list-allocations - List allocations available in verified registry actor or made by a client if specified

USAGE:
   lotus filplus list-allocations [command options] clientAddress

OPTIONS:

   --json      output results in json format (default: false)
   --help, -h  show help


lotus filplus list-claims --help     
NAME:
   lotus filplus list-claims - List claims available in verified registry actor or made by provider if specified

USAGE:
   lotus filplus list-claims [command options] providerAddress

OPTIONS:
   --expired   list only expired claims (default: false)

# v1.25.2 / 2024-01-11 

This is an optional but **highly recommended feature release** of Lotus, as it includes fixes for synchronizations issues that users have experienced. The feature release also introduces `Lotus-Provider` in its alpha testing phase, as well as the ability to call external PC2-binaries during the sealing process.

## ☢️ Upgrade Warnings ☢️

There are no upgrade warnings for this feature release.

## ⭐️ Highlights ⭐️

### Lotus-Provider
The feature release ships the alpha release of the new Lotus-Provider binary, together with its initial features - High Availability of WindowPoSt and WinningPoSt.

So what is so exciting about Lotus-Provider:

**High Availability**
- You can run as many `Lotus-Provider` instances as you want for both WindowPoSt and WinningPOSt.
- You can connect them to as many clustered Yugabyte instances as you want to. This allows for an NxN configuration where all instances can communicate with all others.
- You have the option to connect different instances to different chain daemons.

**Simplicity**
- Once the configuration is in the database, setting up a new machine with Lotus-Provider is straightforward. Simply start the binary with the correct flags to find YugabyteDB and specify which configuration layers it should use.

**Durability**
- `Lotus-Provider` is designed with robustness in mind. Updates to the system are handled seamlessly, ensuring that performance and stability are maintained when taking down machines in your cluster for updates.

Read more about [`Lotus-Provider` in the documentation here](https://lotus.filecoin.io/storage-providers/lotus-provider/overview/). And check out the how you can migrate from [Lotus-Miner to Lotus-Provider here](https://lotus.filecoin.io/storage-providers/lotus-provider/setup/). **(Only recommended in testnets while its in Alpha)**

### External PC2-binaries 

In this feature release, storage providers can call external PC2-binaries during the sealing process. This allows storage providers to leverage the SupraSeal PC2 binary, which has been shown to improve sealing speed in the PC2-phase. For instance, our current benchmarks show that an NVIDIA RTX A5000 card was able to complete PC2 in approximately 2.5 minutes.

We have verified that SupraSeal PC2 functions properly with Committed Capacity (CC) sectors, both SyntheticPoReps and non-Synthetic PoReps. However calling SupraSeal PC2 with deal sectors is not supported in this feature release.

For more information on how to use SupraSeal PC2 with your `lotus-worker`, as well as how to use feature, please [refer to the documentation](https://lotus.filecoin.io/tutorials/lotus-miner/supra-seal-pc2/).

# v1.25.1 / 2023-12-09

This is a **highly recommended PATCH RELEASE.**  The patch release fixes the issue were node operators trying to catch up sync were unable to sync large message blocks/epochs due to an increased number of messages on the network.

This patch release allows for up to 10k messages per block. Additionally, it introduces a limit on the amount of data that can be read at once, ensuring the system can handle worst-case scenarios.

## Improvements
- fix: exchange: allow up to 10k messages per block ([filecoin-project/lotus#11506](https://github.com/filecoin-project/lotus/pull/11506))

# v 1.25.0 / 2023-11-22

This is a highly recommended feature release of Lotus. This optional release supports the Filecoin network version 21 upgrade, codenamed Watermelon 🍉, in addition to the numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

**The Filecoin network upgrade v21, codenamed Watermelon 🍉, is at epoch 3469380 - 2023-12-12T13:30:00Z**

The full list of [protocol improvements delivered in the network upgrade can be found here](https://github.com/filecoin-project/core-devs/blob/master/Network%20Upgrades/v21.md).

## ☢️ Upgrade Warnings ☢️

- Read through the [changelog of the mandatory v1.24.0 release](https://github.com/filecoin-project/lotus/releases/tag/v1.24.0). Especially the `Migration` and `v12 Builtin Actor Bundle` sections.
- Please remove and clone a new Lotus repo (`git clone https://github.com/filecoin-project/lotus.git`) when upgrading to this release.
- This feature release requires a minimum Go version of v1.20.7 or higher to successfully build Lotus. Go version 1.21.x is not supported yet.
- EthRPC providers, please check out the [new tracing API to Lotus RPC](https://github.com/filecoin-project/lotus/pull/11100)

## ⭐️ Highlights ⭐️

**Unsealing bugfixes and enhancements**

This feature release introduces significant improvements and bugfixes with regards to unsealing, and ensures that unsealing operates as one would expect. Consequently, unsealing of all sector types (deal sectors, snap-sectors without sector keys, and snap-sectors with sector keys) now all function seamlessly.

Some additional unsealing improvements are:
- Unsealing on workers with only sealing paths works. :tada:
- Transferring unsealed files to long-term storage upon successful unsealing. :arrow_right:
- Ensuring no residual files in sealing paths post a successful unsealing operation. :broom:

**SupraSeal C2**

Lotus-workers can now be built to leverage the SupraSeal C2 sealing optimizations in your sealing pipeline. The code optimizations are currently behind the `FFI_USE_CUDA_SUPRASEAL` feature flag. We advice users to test this feature on a test-network, before trying to use it on the mainnet. Users can test out the feature by building their lotus-workers by exporting the `FFI_USE_CUDA_SUPRASEAL=1` enviroment variable, and building from source. For questions about the SupraSeal C2 sealing optimizations, reach out in the #fil-proofs or the #dsa-sealing slack channel.

## ☢️ Upgrade Warnings ☢️

This feature release requires a minimum Go version of v1.20.7 or higher to successfully build Lotus. Go version 1.21.x is not supported yet.

## v12 Builtin Actor Bundles

[Builtin actor v12.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v12.0.0) is used for supporting this upgrade.
Make sure that your lotus actor bundle matches the v12 actors manifest by running the following cli after upgrading:

```

## Migration

We are expecting a heavier than normal state migration for this upgrade due to the amount of state changes introduced for miner sector info. (This is a similar migration as the Shark upgrade, however, we have introduced a couple of migration performance optimizations since then for a smoother upgrade experience.)

All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 180 epochs before the upgrade, around 2023-12-12T12:00:00Z. It will take around 20-30 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries (during our testing, it topped out about 205 RAM(htop) on a 1TiB box).

We recommend node operators (who haven't enabled splitstore `discard` mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.

Note to full archival node operators: you may expect it takes some time  for the node to complete the final migration, during this period your node will fall out of sync and your chain service may have some disruption. However, you can expect the node to catch up soon after the migration completes. You can test out the migration by running the following on your node in offline mode:

1. `lotus chain head | head -n1`
2. Stop Lotus daemon
3. `./lotus-shed migrate-state --repo=[path-to-your-lotus-repo] 21 [output-of-step-1]`

You can check out the [tutorial for benchmarking the network migration here.](https://lotus.filecoin.io/kb/test-migration/)

# v1.23.3 / 2023-08-01

This feature release of Lotus includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

This feature release requires a **minimum Go version of v1.19.12 or higher to successfully build Lotus**. Go version 1.20 is also supported, but 1.21 is NOT.

## Highlights

- [Lotus now includes a Slasher tool](https://github.com/filecoin-project/lotus/pull/10928) to monitor the network for Consensus Faults, and report them as appropriate
  - The Slasher investigates all incoming blocks, and assesses whether they trigger any of the three Consensus Faults defined in the Filecoin protocol
  - If any faults are detected, the Slasher sends a `ReportConsensusFault` message to the faulty miner
  - For more information on the Slasher, including how to run it, please find the documentation [here](https://lotus.filecoin.io/lotus/manage/slasher-and-disputer/)
- The Ethereum-like RPC exposed by Lotus is now compatible with EIP-1898: https://github.com/filecoin-project/lotus/pull/10815
- The lotus-miner PieceReader now supports parallel reads: https://github.com/filecoin-project/lotus/pull/10913
- Added new environment variable `LOTUS_EXEC_TRACE_CACHE_SIZE` to configure execution trace cache size ([filecoin-project/lotus#10585](https://github.com/filecoin-project/lotus/pull/10585))
  - If unset, we default to caching 16 most recent execution traces. Storage Providers may want to set this to 0, while exchanges may want to crank it up.

## New features
  - feat: miner cli: sectors list upgrade-bounds tool ([filecoin-project/lotus#10923](https://github.com/filecoin-project/lotus/pull/10923))

# v1.23.2 / 2023-06-28

This is a patch release on top of 1.23.1 containing the fix for https://github.com/filecoin-project/lotus/issues/10906
This fixes the syncing issue seen by many node operators/SPs, usually when performing actions which would result in msgs staying in their mpool for longer periods of time (ex. PSD) resulting in these msgs being republished multiple times and possibly lowering your peer scores. Please refer to the above issue for more details.
We'd recommend everyone to accept this fix to better overall network health

## Improvements
- fix: pubsub: do not treat ErrExistingNonce as Reject


# v1.23.1 / 2023-06-20

This is an optional feature release of Lotus. This feature release includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

**☢️ Upgrade Warnings ☢️**

If you are upgrading to this release candidate from Lotus v1.22.1, please make sure to read the upgrade warnings section in the [v1.23.0 release first.](https://github.com/filecoin-project/lotus/releases/tag/v1.23.0)

- *Storage providers:* The Lotus-Miner legacy-markets has been disbled by default in this feature release and will be removed in the near term future. Users are adviced to migrate to [Boost](https://boost.filecoin.io) or other SP markets systems.

## Highlights

**🛣 Execution Lanes 🛣**
This feature release introduces VM Execution Lanes! Execution lanes efficiently divide the workload between system processes  (chainsync) and RPC requests. This way syncing the chain will not be at the mercy of responding to users' requests and RPC providers nodes should have less problems catching up.

To take advantage of VM Execution Lanes, you need to set up two environment variables:
- `LOTUS_FVM_CONCURRENCY` - read more about how this value should be set to [here](https://lotus.filecoin.io/lotus/configure/ethereum-rpc/#environment-variables)
- `LOTUS_FVM_CONCURRENCY_RESERVED = 4` 

**🧱 Aggregation / Batching fixes 🔨**

Numerous aggregation and batching fixes has been included in the feature release. Large `ProveCommitAggregate` and `PreCommitBatching` messages that exceeds the block limit will now automatically be split into smaller messages when sent to the chain.

Additionally we have added a new feature that staggers the amount of ProveCommit messages sent simulatanously to the chain if a storage provider has been aggregating many sectors in ProveCommitAggregate message, but at the time of publishing the BaseFee is below the aggregation threshold. This stagger feature prevents issues where some of the ProveCommit messages fail with the SysErrorOutOfGas message. You can tweak how many messages will be staggered per epoch by changing `MaxSectorProveCommitsSubmittedPerEpoch` in the [sealing section of the config.toml file.](https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#sealing-section)

*NB:* While these fixes are great for the reliability of aggregation and batching on the Lotus side, it has been uncovered that aggregating ProveCommit messages for sectors containing verified deals are currently more expensive then single messages due to an issue on the actors side. We therefore do not reccomend our users to aggregate ProveCommit messages when doing verified deals until that issue has been resolved. You can follow the discussion on resolving the issue on the [actors side here.](https://github.com/filecoin-project/FIPs/discussions/689)

**Unsealing CLI/API**

This feature release adds a dedicated `lotus-miner sectors unseal` command and API, allowing you to unseal specific sealed sectors easily.

## New features
- feat: VM Execution Lanes ([filecoin-project/lotus#10551](https://github.com/filecoin-project/lotus/pull/10551))

# v1.23.0 / 2023-04-21

This is the stable feature release for the upcoming MANDATORY network upgrade at `2023-04-27T13:00:00Z`, epoch `2809800`. This feature release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet, and includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.

## ☢️ Upgrade Warnings ☢️

Please read carefully through the **upgrade warnings** section if you are upgrading from a v1.20.X release, or the v1.22.0 release. If you are upgrading from a v1.21.0-rcX these warnings should be familiar to you.

- Starting from this release, the SplitStore feature is automatically activated on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the `EnableSplitstore` option in your `config.toml` file. To enable SplitStore, set `EnableSplitstore=true`, and to disable it, set `EnableSplitstore=false`. **It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!**
- This feature release requires a **minimum Go version of v1.19.7 or higher to successfully build Lotus**. Additionally, Go version v1.20 and higher is now also supported.
- **Storage Providers:** The proofs libraries now have CUDA enabled by default, which requires you to install [CUDA](https://lotus.filecoin.io/tutorials/lotus-miner/cuda/) if you haven't already done so. If you prefer to use OpenCL on your GPUs instead, you can use the `FFI_USE_OPENCL=1` flag when building from source. On the other hand, if you want to disable GPUs altogether, you can use the `FFI_NO_GPU=1` environment variable when building from source.
- **Storage Providers:** The `lotus-miner sectors extend` command has been refactored to the functionality of `lotus-miner sectors renew`.
- **Exchanges/Node operators/RPC-providers::** Execution traces (returned from `lotus state exec-trace`, `lotus state replay`, etc.), has changed to account for changes introduced by the by the FVM. **Please make sure to read the `Execution trace format change` section carefully, as these are interface breaking changes**
- **Syncing issues:** If you have been struggling with syncing issues in normal operations you can try to adjust the amount of threads used for more concurrent FMV execution through via the `LOTUS_FVM_CONCURRENCY` enviroment variable. It is set to 4 threads by default. Recommended formula for concurrency == YOUR_RAM/4 , but max during a network upgrade is 24. If you are a Storage Provider and are pushing many messages within a short period of time, exporting `LOTUS_SKIP_APPLY_TS_MESSAGE_CALL_WITH_GAS=1` will also help with keeping in sync.
- **Catching up from a Snapshot:** Users have noticed that catching up sync from a snapshot is taking a lot longer these day. This is largely related to the built-in market actor consuming a lot of computational demand for block validation. A FIP for a short-term mitigation for this is currently in Last Call and will be included network version 19 upgrade if accepted. You [can read the FIP here.](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md)

## Highlights

### Execution Trace Format Changes

Execution traces (returned from `lotus state exec-trace`, `lotus state replay`, etc.), has changed to account for changes introduced by the FVM. Specifically:

- The `Msg` field no longer matches the Filecoin message format as many of the message fields didn't make sense in on-chain sub-calls. Instead, it now has the fields `To`, `From`, `Value`, `Method`, `Params`, and `ParamsCodec` where `ParamsCodec` is a new field indicating the IPLD codec of the parameters.
    - Importantly, the `Msg.CID` field has been removed. This field is still present in top-level invocation results, just not inside the execution trace itself.
- The `MsgRct` field no longer includes a `GasUsed` field and now has a `ReturnCodec` field to indicating the IPLD codec of the return value.
- The `Error` and `Duration` fields have been removed as these are not set by the FVM. The top-level message "invocation result" retains the `Error` and `Duration` fields, they've only been removed from the trace itself.
- Gas Charges no longer include "virtual" gas fields (those starting with `v...`) or source location information (`loc`) as neither field is set by the FVM.

A note on "codecs": FVM parameters and return values are IPLD blocks where the "codec" specifies the data encoding. The codec will generally be one of:

- `0x51`, `0x71` - CBOR or DagCBOR. You should generally treat these as equivalent.
- `0x55` - Raw bytes.
- `0x00` - Nothing. If the codec is `0x00`, the parameter and/or return value should be empty and should be treated as "void" (not specified).

**SplitStore**

This feature release introduces numerous improvements and fixes to tackle SplitStore related issues that has been reported. With this feature release SplitStore is automatically activated by default on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the `EnableSplitstore` option in your `config.toml` file. To enable SplitStore, set `EnableSplitstore=true`, and to disable it, set `EnableSplitstore=false`. **It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!**

SplitStore also has some new configuration settings that you can set in your config.toml file:
- `HotstoreMaxSpaceTarget` suggests the max allowed space (in bytes) the hotstore can take.
- `HotstoreMaxSpaceThreshold` a moving GC will be triggered when total moving size exceeds this threshold (in bytes).
- `HotstoreMaxSpaceSafetyBuffer` a safety buffer to prevent moving GC from an overflowing disk.

The SplitStore also has two new commands:

- `lotus chain prune hot` is a much less resource-intensive GC and is best suited for situations where you don't have the spare disk space for a full GC.
- `lotus chain prune hot-moving` will run a full moving garbage collection of the hotstore. This commands create a new hotstore before deleting the old one so you need working room in the hotstore directory. The current size of a fully GC'd hotstore is around 295 GiB so you need to make sure you have at least that available.

You can read more about the new SplitStore commands in [the documentation](https://lotus.filecoin.io/lotus/configure/splitstore/#manual-chain-store-garbage-collection).

**RPC API improvements**

This feature release includes all the RPC API improvements made in the Lotus v1.20.x patch releases. It includes an updated FFI that sets the FVM parallelism to 4 by default.

Node operators with higher memory specs can experiment with setting LOTUS_FVM_CONCURRENCY to higher values, up to 48, to allow for more concurrent FVM execution.

**Experimental scheduler assigners**

In this release there are four new expirmental scheduler assigners:

- The `experiment-spread-qcount` - similar to the spread assigner but also takes into account task counts which are in running/preparing/queued states.
- The `experiment-spread-tasks` - similar to the spread assigner, but counts running tasks on a per-task-type basis
- The `experiment-spread-tasks-qcount` -  similar to the spread assigner, but also takes into account task counts which are in running/preparing/queued states, as well as counting running tasks on a per-task-type basis. Check the results for this assigner on ([storage-only lotus-workers here](https://github.com/filecoin-project/lotus/issues/8566#issuecomment-1446978856)).
- The `experiment-random` - In each schedule loop the assinger figures a set of all workers which can handle the task and then picks a random one. Check the results for this assigner on ([storage-only lotus-workers here](https://github.com/filecoin-project/lotus/issues/8566#issuecomment-1447064218)).

**Graceful shutdown of lotus-workers**
We have cleaned up some commands in the `lotus-worker` to make it less confusing how to gracefully shutting down a `lotus-worker` while there are incoming sealing tasks in the pipeline. To shut down a `lotus-worker` gracefully:

1. `lotus-worker tasks disable --all` and wait for the worker to finish processing its current tasks.
2. `lotus-worker stop` to detach it and do maintenance/upgrades.

**CLI speedups**

The `lotus-miner sector list` is now running in parallel - which should speed up the process from anywhere between 2x-10x+. You can tune it additionally with the `check-parallelism` option in the command. The `Lotus-Miner info` command also has a large speed improvement, as calls to the lotus legacy market has been removed.

# v1.22.1 / 2023-04-23

## Important Notice

This is a MANDATORY hotfix release that fixes a consensus-critical bug that was in v1.22.0 -- the necessary fix is https://github.com/filecoin-project/ref-fvm/pull/1750 and it is integrated into lotus via https://github.com/filecoin-project/lotus/pull/10735.
You can NOT use 1.22.0 for the nv19 upgrade, you MUST be on 1.22.1 or higher.

## About This Release

This is the stable release of Lotus v1.22.1 for the upcoming MANDATORY network upgrade at `2023-04-27T13:00:00Z`, epoch `2809800`. This release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet.

Note that you must be on a go version higher than Go 1.18.8, but lower than Go v1.20.0. We would recommend Go 1.19.7.

The Lighting and Thunder upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors [v11.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0-rc2)):

- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - Fallback method handler for multisig actor

## Expedited nv19 Lightning ⚡️ rollout

In light of the recent degraded chain quality on the mainnet [an expedited nv19 upgrade has been proposed and accepted](https://github.com/filecoin-project/core-devs/discussions/123#discussioncomment-5642909) to roll out the market cron mitigation ([FIP0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md)) that will improve block validation times, and with that the delay in block production that is causing a decrease in the chain quality currently.

With this expedited roll out we want to inform you of some **key changes and important dates:**

- Accelerate the nv19-upgrade on **mainnet** from May 11th to **April 27th**.
- Derisk nv19 by descoping the sector info migration, activation epoch fixes and drop [[FIP0052 - Extend sector/deal max duration to 3.5 year.](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
  - By descoping these changes we can greatly derisk the network upgrade itself by removing a heavy migration that could cause instability for storage providers and node operators during the network upgrade.
- Increase the rollover period for [[FIP0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md) from 1 week to 3 weeks on mainnet. The rollover period is the duration between nv19 and nv20 which both old proofs (v1) and the new proofs (v1_1) proofs will be accepted by the network.

The Lighting and Thunder upgrade now implements the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors [v11.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0)):

- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - Fallback method handler for multisig actor

# v1.20.4 / 2023-03-17

This is a patch release intended to alleviate performance issues reported by some users since the nv18 upgrade. 
The primary change is to update the FFI to allow for FVM parallelism of 4 by default, and make this user-configurable.
through the `LOTUS_FVM_CONCURRENCY` env var. 

Users with higher memory specs can experiment with setting `LOTUS_FVM_CONCURRENCY` to higher values, up to 48, to allow for more concurrent FVM execution.

## Bug fixes

- Splitstore: Don't enforce walking receipt tree during compaction #10505
- fix: build: drop drand incentinet servers #10506 

## Improvement

- chore: update ffi to increase execution parallelism #10503

# 1.20.0 / 2023-02-28

This is a MANDATORY release of Lotus that delivers the [Hygge network upgrade](https://github.com/filecoin-project/community/discussions/74?sort=top#discussioncomment-4313888), introducing Filecoin network version 18. The centerpiece of the upgrade is the introduction of the [Filecoin Virtual Machine (FVM)’s Milestone 2.1](https://fvm.filecoin.io/), which will allow for EVM-compatible contracts to be deployed on the Filecoin network. This upgrade delivers user-programmablity to the Filecoin network for the first time!

The Filecoin mainnet is scheduled to upgrade to nv18 at epoch 2683348, on March 14th at 2023-03-14T15:14:00Z. All node operators, including storage providers, must upgrade to this release before that time. Storage providers must update their daemons, miners, market and worker(s)/boost.
At the upgrade, a short migration will run that converts code actors v9 code CIDs to v10 CIDs, and installs the new Ethereum Address Manager singleton (see below). This is expected to be a lightweight migration that causes no service disruption.

The Hygge upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered in FVM3 (see FVM [v3.0.0](https://github.com/filecoin-project/ref-fvm/pull/1683)) and builtin-actors v10 (see actors [v10.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v10.0.0)):

## Filecoin Ethereum Virtual Machine (FEVM)

The Filecoin Ethereum Virtual Machine (FEVM) is built on top of the WASM-based execution environment introduced in the Skyr v16 upgrade. The chief feature introduced is the ability for anyone participating in the Filecoin network to deploy their own EVM-compatible contracts onto the blockchain, and invoke them as appropriate.

## New Built-in Actors

The FEVM is principally delivered through the introduction of **the new [EVM actor](https://github.com/filecoin-project/builtin-actors/tree/master/actors/evm)**. This actor “represents” smart contracts on the Filecoin network, and includes an interpreter that implements all EVM opcodes as their Filecoin equivalents, and translates state I/O operations to be compatible with Filecoin’s IPLD-based data model. For more on the EVM actors, please see [FIP-0054](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0054.md).

The creation of EVM actors is managed by **the new** [Ethereum Address Manager actor (EAM)](https://github.com/filecoin-project/builtin-actors/tree/master/actors/eam), a singleton that is invoked in order to deploy EVM actors. In order to make usage of the FEVM as seamless as possible for users familiar with the Ethereum ecosystem, this upgrades also introduces **a dedicated actor to serve as “[Ethereum Accounts](https://github.com/filecoin-project/builtin-actors/tree/master/actors/ethaccount)”**. This actor exists to allow for secp keys to be used in the Ethereum addressing scheme. **The last new built-in actor introduced is [the Placeholder actor](https://github.com/filecoin-project/builtin-actors/tree/master/actors/placeholder)**, a thin “shell” of an actor that can transform into either EVM or EthAccount actors. For more on the EAM, EthAccount, and Placeholder actors, please see [FIP-0055](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0055.md).

### v10 Built-in actor bundles

Bundles for all networks (mainnet, calibnet, etc.) are included in the lotus source tree (`build/actors/`) and embedded on build, for v10 actors you can find it [here](https://github.com/filecoin-project/lotus/blob/master/build/actors/v10.tar.zst). 
Reminder: Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in `build/builtin_actors_gen.go`, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running `lotus state actor-cids --network-version 18`.

The manifest CID & full list of actor code CIDs for nv18 using [actor v10](https://github.com/filecoin-project/builtin-actors/releases/tag/v10.0.0) is:

## Node Operators

FVM has been running in lotus since v1.16.0 and up, and the new FEVM does not increase any node hardware spec requirement.

With FEVM on Filecoin, we aim to provide full compatibility with the existing EVM ecosystem and its tooling out of the box. 
Consequently, lotus now provides a full set of [Ethereum-styled APIs](https://github.com/filecoin-project/lotus/blob/release/v1.20.0/node/impl/full/eth.go) for developers and token holders to interact with the Filecoin network as well.
For full documentation on this new tooling, please see the [Lotus docs website](https://lotus.filecoin.io/lotus/configure/ethereum-rpc/).

**Enabling Ethereum JSON RPC API**

Note that Ethereum APIs are only supported in the lotus v1 API, meaning that any node operator who wants to enable Eth API services must be using the v1 API, instead of the v0 API. To enable Eth RPC, simply set `EnableEthRPC` to `true` in your node config.toml file; or set env var `LOTUS_FEVM_ENABLEETHRPC` to `1` before starting your lotus node.

**Eth tx hash and Filecoin message CID**

Most of the Eth APIs take Eth accounts and tx has as an input, and they start with `0x` , and that is what Ethereum tooling support. However, in Filecoin, we have Filecoin account formats where things start with `f` (`f410` specifically for eth accounts on Filecoin) and the messages are in the format of CIDs. To enable a smooth developer experience, Lotus internally converts between Ethereum address and Filecoin account address as needed. In addition, lotus also keeps a Eth tx hash <> Filecoin message CID map and stores them in a SQLite database as node sees a FEVM messages. The database is initiated and the maps are populated  automatically in `~/<lotus_repo>/sqlite/txhash.db` for any node that as Eth RPC enabled. Node operators can configure how many historical mappings they wanna store by configuring `EthTxHashMappingLifetimeDays` .

**Events**

[FIP-0049 introduces actor events](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0049.md) that can be emitted and externally observable during message execution. An `events.db` is created automatically under `~/<lotus_repo>/sqlite` to store these events if the node has Eth RPC enabled. Node operators can configure the events support base on their needs by configuration `Events` configurations.

Note: All three features are new, and we welcome user feedback, please create an issue if you have any enhancements that you’d like to see!

# 1.19.0 / 2022-12-07

This is an optional feature release of Lotus. This feature release includes the SplitStore beta, the experimental Lotus node cluster feature, as well as numerous enhancments and bugfixes.

## Highlights
### 🟢 SplitStore v2（Beta) 🟢

Splitstore aims to reduce the node performance impact that's caused by the Filecoin's very large, and continuously growing chain datastore by having a hot and cold blockstore. You can find more about the Splitstore implementation [here](https://github.com/filecoin-project/lotus/blob/master/blockstore/splitstore/README.md).
Splitstore has three basic modes for node operators to configure according to your needs: 
- `discard`: hotstore only, automatically archive out-of-scope objects that are beyond 4 finalities(3600 epochs).
- `universal`:  stores all chain data that's beyond 4 finalities into coldstore.
- `messages`: only stores on-chain messages into coldstore.

The `EnableColdStoreAutoPrune=` configuration is being deprecated in this release, as there is only ever one compaction running. We welcome all node operators to try the new feature and let us know [here](https://github.com/filecoin-project/lotus/discussions/9179) if you have any feedback! 
There are more configuration one may set, you can read the full documentation about the SplitStoreV2 here: https://lotus.filecoin.io/lotus/configure/splitstore/.

### 🧪 Node Cluster (*EXPERIMENTAL.*) 🧪
The Lotus HA node cluster feature allows you to run multiple Lotus daemons for the same lotus-miner increasing resiliency. We welcome all Lotus users to join the early testing for this feature and provide your feedback. Please note that this feature is targeted towards more enterprise users of Lotus and requires at least 3 lotus nodes to be set up in a cluster.
Check out the documentation here: https://lotus.filecoin.io/lotus/configure/clusters/

### ⭐️ SnapDeals Enhancements ⭐️
Numerous SnapDeals related improvements and fixes made it into this release before the code freeze. Some the highlights of the issues that has been fixed in this feature release are:

- *Unable to snap-up a sector again if something went wrong.* - This has now been fixed ✅
- *Error messages on loop during an open deadline.* - This has now been fixed ✅

## New features
- feat:splitstore:single compaction that can handle prune aka two marksets one compaction (#9571) ([filecoin-project/lotus#9571](https://github.com/filecoin-project/lotus/pull/9571))
   - Introduces a new SplitStore-mode, `messages`, which will only store on-chain messages. Fixes previously issues with regards to `AutoPrune` not compacting the coldstore. [Link to documentation](https://lotus.filecoin.io/lotus/configure/splitstore/)
- feat: Raft consensus for lotus nodes in a cluster ([filecoin-project/lotus#9294](https://github.com/filecoin-project/lotus/pull/9294))
   - Adds the experimental node cluster feature.
- feat: storage: Force exit GenerateSingleVanillaProof on cancelled context ([filecoin-project/lotus#9613](https://github.com/filecoin-project/lotus/pull/9613))
   - `GenerateSingleVanillaProof` now respects context, which means that it will skip slow to read sectors :snail: and return a context error. Instead of being blocked forever if storage reads where blocked (e.g disconnected NFS).
- feat: wdpost: Configurable pre-check timeouts ([filecoin-project/lotus#9680](https://github.com/filecoin-project/lotus/pull/9680))
   - Adds configuration knobs for setting custom amount of time a proving pre-check can take before a sector and partition will be skipped. [Link to documentation](https://lotus.filecoin.io/storage-providers/advanced-configurations/proving/#pre-check-sector-timeout)
- feat: chain: future proof the from & to address protocols ([filecoin-project/lotus#9515](https://github.com/filecoin-project/lotus/pull/9515))
   - This lets us add new address protocols to go-address without implicitly accepting them in messages on the network.
- feat: Retrieval into remote blockstores ([filecoin-project/lotus#9565](https://github.com/filecoin-project/lotus/pull/9565))
   - Makes it possible to point retrievals at a network-backed blockstore.
- feat: Add node uptime rpc / output in info command ([filecoin-project/lotus#9436](https://github.com/filecoin-project/lotus/pull/9436))
   - Adds node uptime stats to the `lotus-miner info` and `lotus info` commands
- feat: wdpost: Add ability to only have single partition per msg for partitions with… ([filecoin-project/lotus#9413](https://github.com/filecoin-project/lotus/pull/9413))
  - Adds a configuration option to have a single partition per PoSt Message for partitions containing recovering sectors.
- feat: miner paramfetch: Don't fetch param files when not needed ([filecoin-project/lotus#9391](https://github.com/filecoin-project/lotus/pull/9391))
   - A Lotus-Miner processes that has disabled local PoSt / C2 / PR2 does not need the param-files. This makes node startup much faster, reducing downtime by a lot when restarts are needed.
- feat: client: Add retrieval deal ID and bytes transferred to retrieval output ([filecoin-project/lotus#9398](https://github.com/filecoin-project/lotus/pull/9398))
   - Appends retrieval deal ID and bytes transferred to the retrieval output.
- feat: dealpublisher: check for duplicate deals before adding ([filecoin-project/lotus#9365](https://github.com/filecoin-project/lotus/pull/9365))
- feat: Drop active retrieval check (#764) ([filecoin-project/go-fil-markets#764](https://github.com/filecoin-project/go-fil-markets/pull/764))
- feat(retrievalmarkets): expose GetDynamicAsk (#748) ([filecoin-project/go-fil-markets#748](https://github.com/filecoin-project/go-fil-markets/pull/748))
- feat: handle retrieval queries for unindexed identity payload CIDs (#747) ([filecoin-project/go-fil-markets#747](https://github.com/filecoin-project/go-fil-markets/pull/747))
- feat: add a method for validating an address for a network version (#115) ([filecoin-project/go-state-types#115](https://github.com/filecoin-project/go-state-types/pull/115))

## Improvements
- fix: miner-cli: Fix lotus-miner proving check ([filecoin-project/lotus#9643](https://github.com/filecoin-project/lotus/pull/9643))
   - Fixes the issue where the `lotus-miner proving check` command always outputted `Error: rg is nil`
- fix: sealing pipeline: Clear CreationTime when starting sector upgrade ([filecoin-project/lotus#9642](https://github.com/filecoin-project/lotus/pull/9642))
   - Fixes the issue where an aborted SnapDeal upgrade could no longer be retried with SnapDeals.
- fix:sealing-fsm:wait mutable fsm state for immutable sector upgrade error ([filecoin-project/lotus#9598](https://github.com/filecoin-project/lotus/pull/9598))
   - Creating a new WaitMutable state - now if the deadline is open and the sectors are trying finalize they will wait on the worker until the deadline has closed. Important to note that they will not finalize as soon as the deadline closes, they will wait 1h before continuing. Fixes the previous issue where upgraded Snap-sectors for an open deadline cause a lot of `error-messages` and `p_aux` issues
- fix: cli: add beneficiary info to lotus-miner actor control list ([filecoin-project/lotus#9632](https://github.com/filecoin-project/lotus/pull/9632))

- fix: docker: make compatible with arm platform ([filecoin-project/lotus#9363](https://github.com/filecoin-project/lotus/pull/9363))
   - Makes the `Dockerfile.lotus` compatible with ARM-platforms (e.g Mac M1).
- fix: post worker sched: Don't check worker session in a busy loop ([filecoin-project/lotus#9495](https://github.com/filecoin-project/lotus/pull/9495))
   - Fixes a looping pattern which could result in a flood of requests between `lotus-miner`<->`lotus-worker`, potentially exhausting resources needed to make http requests, that lead to all sorts of random RPC-related issues.
- fix: miner: init miner's with 32GiB sectors by default ([filecoin-project/lotus#9364](https://github.com/filecoin-project/lotus/pull/9364))
   - Makes the `lotus-miner init` defualt to 32GiB sectors.
- fix: store identity CIDs in CARs for online deals (#749) ([filecoin-project/go-fil-markets#749](https://github.com/filecoin-project/go-fil-markets/pull/749))

# 1.18.2 / 2022-12-10

This is an OPTIONAL patch release that fixes a recently reported bug, where the miner process crashes due to a panic during an AddPiece process. More details can be found [here](https://github.com/filecoin-project/lotus/pull/9822).


# 1.18.1 / 2022-11-28

This is a small OPTIONAL patch release for the mandatory v1.18.0 release that supports the Filecoin nv17 Shark Upgrade. 
We highly recommend you to read the full [v1.18.0 release note](https://github.com/filecoin-project/lotus/releases/tag/v1.18.0) if you haven't already.

Note to SPs:
If you are running into issue with updating your miner node from an earlier release and is failing to restart your miner, check your `journalctl` and see if you noticed the following error:
```
New sector storage: <%d>
Nov 19 15:03:43 g0lotus01 lotus-miner[<id>]: ERROR: creating node: starting node: could not build arguments for function "reflect".makeFuncStub (/usr/local/go/src/reflect/asm_amd64.s:28): failed to build *paths.Local: received non-nil error from function "reflect".makeFuncStub (/usr/local/go/src/reflect/asm_amd64.s:28): opening path /media/data1/lotusstorage: path with ID <%d> already opened: '<path>'
```
If so, this check is introduced via [#9032](https://github.com/filecoin-project/lotus/pull/9032), precisely this [line](https://github.com/filecoin-project/lotus/blame/master/storage/paths/local.go#L164-L166
). It's added to prevents double-attaching paths given it's now possible to manipulate paths at runtime. Verify storage.json configs if you encounter this error or remove the undesired depulicated path as you see fit accordingly.

## Bug Fixes

- fix: cli: check found before dereferencing SectorInfo #9703

# 1.18.0 / 2022-11-15

> ⚠️ **Please note that from Lotus v1.17.2&^ will require a Go-version of v1.18.1&^**

This is the final release of the upcoming MANDATORY release of Lotus that introduces [Filecoin network v17,
codenamed the Shark upgrade](https://github.com/filecoin-project/community/discussions/74?sort=top#discussioncomment-3825422). Shark upgrade delivers a wave of protocol refinements that will allow for useful smart contracts to be written using the FVM (eg. programmable markets, lending contracts, etc.).

**The Filecoin mainnet is scheduled to upgrade to nv17 at epoch 2383680, on Nov 30th on 2022-11-30T14:00:00Z. All node operators, including storage providers, must upgrade to this release before that time. Storage providers must update their daemons, miners, market and worker(s)/boost.**

The Shark upgrade introduces the following FIPs, delivered in [actors v9](https://github.com/filecoin-project/builtin-actors/releases/tag/v9.0.3):
- [FIP0029 Beneficiary Address for Storage Providers](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0029.md): step towards better lending market for SP
- [FIP0034 Fix PreCommit Deposit Independent of Sector Content](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0034.md): resolves a significant weakening of Filecoin PoRep’s security guarantees
  - ❗Pre-commit deposit will be calculated as the 20-day projection of expected reward earned by a sector with **a sector quality of 10 (i.e. full of verified deals)**, regardless of sector content. The Initial Pledge value, due when the sector is proven, is left **unchanged**.
- [FIP0041 Forward Compatibility for PreCommit](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0041.md): enables a cleaner and easier transition to Programmable Storage Markets
- [FIP0044 Standard Message Authentication](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0044.md): enable metadata authentication for user defined actor
- [FIP0045 Decoupling Fil+ from Marketplace](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0045.md): DataCap and the 10x QAP is now only associated with how long DATA is wanted to be stored on the network.
  - This is a transitional state to enabling far more efficient and dynamic storage markets on Filecoin network in the future.
  - ⭐️ First Fungible Token Contract - Datacap Actor, on Filecoin!  ([fungible token standard](https://github.com/filecoin-project/FIPs/blob/master/FRCs/frc-0046.md), [token contract library](https://github.com/helix-onchain/filecoin/tree/5455f4f831e0f3f20005a9a789623d7ad6dada15/frc46_token)).
  - For storage deal participants (clients and storage providers):
    - `PublishStorageDeals`/`ProveCommit(Aggregate)`/`ProveReplicaUpdates` message that includes verified deals will see a gas usage increase, more details can be found [here](https://github.com/filecoin-project/FIPs/blob/385f069b3b146c5fef4fdc1109a0e2f35f399e48/FIPS/fip-0045.md?plain=1#L784)
    -  `Term` is introduced for defining how long the DataCap is assigned to a piece of data. Anyone who cares about that piece of data may extend the _term_, which incentives SPs to store the data longer on the network without a new deal/resealing.
    - There is no  more diluted verified deal QAP due to deal/sector space time for new sectors that contains verified deals after this upgrade.
    - SPs may enjoy 90 days of extra QAP than deal duration by default, given `term_max` is always `deal duration + 90 days`.
❗ We highly recommend all lotus users, especially storage providers, developers and clients to read the FIPs in detail to understand the protocol changes and potential impact to network participants!
      
## Snapshots

The [#fil-infra](https://filecoinproject.slack.com/archives/C039RBG3RPC) team at PL has launched a brand new Lightweight Filecoin Chain Snapshots Service to support chain management needs for the node operators, check [here](https://www.notion.so/pl-strflt/Lightweight-Filecoin-Chain-Snapshots-17e4c386f35c44548f5863afb7b5e024) for the full detail. 
We are planning to switch [the snapshot service listed in lotus docs](https://lotus.filecoin.io/lotus/manage/chain-management/#lightweight-snapshot) to the new Lightweight Filecoin Chain Snapshots Service by EOY, and deprecate public support of the current snapshots production. We recommend all users to test and switch the new service ASAP, and if you run into any issue, please report them [here](https://github.com/filecoin-project/filecoin-chain-archiver/discussions/new?category=feedback) and the team would be happy to support you! For the main differences between the old & the new service, checkout the FAQ section [here](https://www.notion.so/pl-strflt/Lightweight-Filecoin-Chain-Snapshots-17e4c386f35c44548f5863afb7b5e024)

## Migration 

We are expecting a heavier than normal state migration for this upgrade due to the amount of the state changes introduced.
All node operators, including storage providers, should be aware that two pre-migrations are being scheduled. The first pre-migration will begin at 2022-11-30T12:00:00Z (120 minutes before the real upgrade), the second pre-migration will begin at 2022-11-30T13:45:00Z (7.5 minutes before the real upgrade). 
The first pre-migration will take up to 1.5hr, depending on the amount of the historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries. 
We recommend node operators (who haven't enbabled splistore `universal` mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.
Note to full archival node operators: you may expect a migration that takes up to 20 min upon the upgrade, during this period your node will fall out of sync and your chain service may have some disruption. However, you can expect the node to catch up soon after the migration completes.

### v9 Built-in actor bundles

Bundles for all networks(mainnet, calibnet, and etc) are included in the lotus source tree (`build/actors/`) and embedded on build, for v9 actors you can find it [here](https://github.com/filecoin-project/lotus/blob/master/build/actors/v9.tar.zst). 
Reminder: Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in `build/builtin_actors_gen.go`, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running `lotus state actor-cids --network-version 17`.

The manifest CID & full list of actor code CIDs for nv17 using [actor v9](https://github.com/filecoin-project/builtin-actors/releases/tag/v9.0.3) is:

# v1.17.2 / 2022-10-05

This is an OPTIONAL release of Lotus. This feature release introduces new sector number management APIs in Lotus that enables all the Sealing-as-a-Service and Lotus interactions needed to function. The default propagation delay setting for storage providers has also been changed, as well as numerous other features and enhancements. Check out the sub-bullet points in the feature and enhancement section to get a short description about each feature and enhancements.

### Highlights

🦭 **SaaS** 🦭
New sector management APIs makes it possible to import partially sealed sectors into Lotus. This release implements all SaaS<->Lotus interactions needed for such services to work. Deep dive into the new APIs here: https://github.com/filecoin-project/lotus/discussions/9079#discussioncomment-3652044

⏳ **Propagation delay** ⌛️
In v1.17.2 the default PropagationDelay has been raised from 6 seconds -> 10 seconds, and you can tune this yourself with the `PROPAGATION_DELAY_SECS` environment variable. This means you will now wait for 10 seconds for other blocks to arrive from the network before computing a winningPoSt (if eligible). In your `lotus-miner` logs that means you will see this "baseDeltaSeconds": 10 as default.

⚠️ **Please note that Lotus v1.17.2 will require a Go-version of v1.18.1 or higher!**

## New features
- feat: sealing: Partially sealed sector import ([filecoin-project/lotus#9210](https://github.com/filecoin-project/lotus/pull/9210))
  - Implements support for importing (partially) sealed sectors which is needed for enabling external sealing services.
- feat: sealing: Use bitfields to manage sector numbers ([filecoin-project/lotus#9183](https://github.com/filecoin-project/lotus/pull/9183))
  - Needed for Sealing-as-a-Service. Move sector number assigning logic to use stored bitfields instead of stored counters. Makes it possible to reserve ranges of sector numbers, see the sector assigner state and view sector number reservations.
- feat: env: propagation delay ([filecoin-project/lotus#9290](https://github.com/filecoin-project/lotus/pull/9290))
  - The default propagation delay is raised to 10 seconds from 6 seconds. Ability to set it yourself with the `PROPAGATION_DELAY_SECS` environment variable.
- feat: cli: lotus info cmd ([filecoin-project/lotus#9233](https://github.com/filecoin-project/lotus/pull/9233))
  - A new `lotus info` command that prints useful node information in one place.
- feat: proving: Introduce manual sector fault recovery (#9144) ([filecoin-project/lotus#9144](https://github.com/filecoin-project/lotus/pull/9144))
  - Allow users to declare fault recovery messages manually with the `lotus-miner proving recover-faults` command, rather than waiting for it to happen automatically before windowPost.
- feat: api: Reintroduce StateActorManifestCID ([filecoin-project/lotus#9201](https://github.com/filecoin-project/lotus/pull/9201))
  - Adds ability to retrieve the Actor Manifest CID through the api.
- feat: message: Add uuid to mpool message sent to chain node from miner ([filecoin-project/lotus#9174](https://github.com/filecoin-project/lotus/pull/9174))
  - Adds a UUID to each message sent by the `lotus-miner` to the daemon. A requirement needed for https://github.com/filecoin-project/lotus/issues/9130
- feat: message: Add retries to mpool push message from lotus-miner ([filecoin-project/lotus#9177](https://github.com/filecoin-project/lotus/pull/9177))
  - Retries to mpool push message API in case of unavailability of the lotus chain node.

**Network 17 related features :**
- feat: network: add nv17 and integrate the corresponding go state type ([filecoin-project/lotus#9267](https://github.com/filecoin-project/lotus/pull/9267))
- feat: cli: print beneficiary info in state miner-info ([filecoin-project/lotus#9308](https://github.com/filecoin-project/lotus/pull/9308))
- feat: api/cli: change beneficiary propose and confirm for actors and multisigs. ([filecoin-project/lotus#9307](https://github.com/filecoin-project/lotus/pull/9307))
- feat: api/cli: beneficiary withdraw api and cli ([filecoin-project/lotus#9296](https://github.com/filecoin-project/lotus/pull/9296))

## Enhancements
- feat: sectors renew --only-cc ([filecoin-project/lotus#9184](https://github.com/filecoin-project/lotus/pull/9184))
  - Exlude extending deal-related sectors with the `--only-cc` option when using the `lotus-miner sectors renew`

  - Show amount of `updated` & `update-cache` sectors in each storage path in the `lotus-miner storage list` output
- feat: add descriptive errors to markets event handler ([filecoin-project/lotus#9326](https://github.com/filecoin-project/lotus/pull/9326))
  - More descriptive market error logs
- feat: cli: Add option to terminate sectors from worker address ([filecoin-project/lotus#9291](https://github.com/filecoin-project/lotus/pull/9291))
  - Adds a flag to allow either owner address or worker address to send terminate sectors message.
- fix: cli: actor-cids cli command now defaults to current network ([filecoin-project/lotus#9321](https://github.com/filecoin-project/lotus/pull/9321))
  - Makes the command defaults to the current network.
- fix: ux: Output bytes in `lotus client commP` cmd ([filecoin-project/lotus#9189](https://github.com/filecoin-project/lotus/pull/9189))
  - Adds an additional line that outputs bytes in the `lotus client commP` command.
- fix: sealing: Add information on what worker a job was assigned to in logs ([filecoin-project/lotus#9151](https://github.com/filecoin-project/lotus/pull/9151))
  - Adds the worker hostname into the assignment logs.
- refactor: sealing pipeline: Remove useless storage adapter code ([filecoin-project/lotus#9142](https://github.com/filecoin-project/lotus/pull/9142)
  - Remove proxy code in `storage/miner.go` / `storage/miner_sealing.go`, call the pipeline directly instead.

# 1.16.0 / 2022-06-24

This is a MANDATORY release of Lotus that introduces [Filecoin network v16,
codenamed the Skyr upgrade](https://github.com/filecoin-project/community/discussions/74?sort=new#discussioncomment-2392151).

The network is scheduled to upgrade to nv16 at epoch 1960320, on July 6th at 2022-07-06T14:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, market and worker(s).

Your lotus node will switch from the Legacy VM (that depended on go-based specs-actors) to Filecoin Virtual Machine FVM (that uses Rust-based builtin-actors) atomically upon the upgrade.

The Skyr upgrade introduces the following FIPs, enhancements and bug fixes, delivered in [built-actors v8](https://github.com/filecoin-project/builtin-actors/releases/tag/v8.0.0) and [ref-fvm v1.0.0](https://github.com/filecoin-project/ref-fvm/releases/tag/fvm%40v1.0.0):,

- [FIP-0030](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0030.md)
- [FIP-0031](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md)
- [FIP-0032](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0032.md))
- [FIP-0027](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0027.md)
- [Bug fix for the ProveReplicaUpdates method](https://github.com/filecoin-project/builtin-actors/pull/138)
- [New proofs version for SnarkPack](https://github.com/filecoin-project/builtin-actors/pull/474/commits/3027c365f516e1cba6f156d4fb9dbd8c893d5b62)


## 🆕 Things you may wanna know

### Actor Code CIDs

As stated in [FIP-0031](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md)- [structure of the code cid](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md#structure-of-code-cids), system actors' code CIDs will be real content-addressing

For lotus users, we are making the change minimal for you. This means the `CODE` output when you run `lotus state get-actor` will now be the actual CID that represents the executable code for the actor, followed by wrapped synthetic id like the ones you've got before, i.e `fil/8/system`.

Moreover, this also means that in the future, whenever the actor code changes, the CID changes accordingly, and a network upgrade is needed for the network participants to have consensus over what executable code we should use for each system actor.

### Built-in actor bundles

As the network introduces FVM, it's also switching from spec-actor (written in GoLang) to [built-in actor](https://github.com/filecoin-project/builtin-actors) (written in rust), in which the latter comes with[ importable bundles](https://github.com/filecoin-project/builtin-actors#importable-bundle). This means, like filecoin proof parameters, node operators now also need to fetch the actor bundles according to the network versions for the nodes to remain operational.

Bundles for all networks(mainnet, calibnet, and etc) are included in the lotus source tree (`build/actors/`) and embedded on build. Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in `build/builtin_actors_gen.go`, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running `lotus state actor-cids --network-version 16`.

The manifest CID & full list of actor code CIDs for nv16 using v8.0.0 is:

```
    "_manifest":         "bafy2bzacebogjbpiemi7npzxchgcjjki3tfxon4ims55obfyfleqntteljsea"
	"account":          "bafk2bzacedudbf7fc5va57t3tmo63snmt3en4iaidv4vo3qlyacbxaa6hlx6y"

	"verifiedregistry": "bafk2bzaceb3zbkjz3auizmoln2unmxep7dyfcmsre64vnqfhdyh7rkqfoxlw4"
```

All bundles are also available at https://github.com/filecoin-project/builtin-actors/releases, thus you can also manually download the bundles and place them in the right path.

Note: use customized bundle will risk you to lose sync with the network!

To get Code CIDs:
- api:`StateActorCodeCIDs`
- cli: `lotus state actor-cids`
- cli: `lotus-shed cid inspect-bundle`

### Execution Trace

For developers that are dependent on lotus execution trace, you will need  to enable `LOTUS_VM_ENABLE_TRACING` envvar to get the exact execution trace response as before. Without the envvar enabled, `Subcall` details, Duration` and `GasCharges` fields will be missing from the new FVM trace.

### Deal Proposal Migration

All deal proposals with non-utf8 string as the label in the metadata store will perform a light migration to new format as defined in [v1.1.1](https://github.com/filecoin-project/go-fil-markets/pull/721).

## Others
- Resource manager is now only enabled by default on full daemon node. You can enable it manually for other nodes by setting env var `LOTUS_RCMGR` to `1`.

# 1.15.2 / 2022-05-06

This is a highly recommended feature lotus release v1.15.2. This feature release introduces many new features and  for SPs, including PoSt workers, sealing scheduler, snap deal queue and so on.

Note: You need to be using go v1.18.1&up from this release onwards.

## Highlights
### ❣️❣️❣️ PoSt Workers ❣️❣️❣️
‼️️Attention - the long-awaited yet highly requested PoSt workers, they are here! And they come in as a combo: you may setup PoSt workers for both winningPoSt or/and windowPoSt worker. You can also setup any number of PoSt workers as long as you have the hardware resources!
For more details and learn how to set it up, see the docs [here](https://lotus.filecoin.io/storage-providers/seal-workers/post-workers/). You can also find early result of the PoSt workers performance by the community [here](https://github.com/filecoin-project/lotus/discussions/8375).
- feat: PoSt workers ([filecoin-project/lotus#7971](https://github.com/filecoin-project/lotus/pull/7971))
- feat: storage: Parallel proving checks ([filecoin-project/lotus#8391](https://github.com/filecoin-project/lotus/pull/8391))
  - adjust `ParallelCheckLimit` according to your resource setup to get pre-post checkers run faster!

In addition, we also added some handy toolings:
- feat: miner: API/CLI to compute window-post ([filecoin-project/lotus#8389](https://github.com/filecoin-project/lotus/pull/8389))
  - run `lotus-miner proving compute window-post` to manually trigger a full windowPoSt computation for a specific deadline for full sanity checks.
- feat: miner cli: Separate proving workers command ([filecoin-project/lotus#8379](https://github.com/filecoin-project/lotus/pull/8379))
  - run `lotus-miner proving workers` to list all the PoSt workers that's attached
- feat: miner cli: proving check --faulty, faults in storage list sectors ([filecoin-project/lotus#8349](https://github.com/filecoin-project/lotus/pull/8349))
  - run `lotus-miner proving check --faulty` to identify the sectors that might be bad.

### 🔥🔥🔥 Sealing Scheduler Enhancement 🔥🔥🔥

Have you ever got a couple workers but only a few of them are super packed, while the rest are idling waiting for jobs? Now the task can be distributed more evenly with:
- feat: sched: Improve worker assigning logic ([filecoin-project/lotus#8447](https://github.com/filecoin-project/lotus/pull/8447))

### 🌟🌟🌟 Snap Deal Enhancements 🌟🌟🌟

The Filecoin Network introduced Snap Deal with the network v15 OhSnap upgrade, and lotus shipped v1.14.0 with basic snappy support for SP to use this feature. Since then, we have received good ux feedbacks and bug reports from the community, and we are introducing a couple enhancement for SPs to better leverage this feature.

# 1.15.1 / 2022-04-07

This is a *HIGHLY recommended* feature release v1.15.1, especially for node operators and storage providers who want to be a part of the content addressing network of Filecoin and IPFS.
This feature release introduces Index Provider, GraphSync v2, and many other latest functionalities, improvements and bug fixes. More importantly, node operator can now enable the FVM(experimental) to sync mainnet!!

## Highlights

### 🔥🔥🔥 FVM (Experimental) 🔥🔥🔥
- feat: fvm: FVM integration  ([filecoin-project/lotus#8332](https://github.com/filecoin-project/lotus/pull/8332))
  The lotus team is excited to announce the launch of experimental non-programmable FVM on mainnet. By enabling `"LOTUS_USE_FVM_EXPERIMENTAL=1` envvar, the lotus daemon will be running the [WASM-compiled built-in actors](https://github.com/filecoin-project/builtin-actors) that is compatible with the existing chain(Network v15 OhSnap). If you are trying it out and having any questions or feedbacks, please leave a comment [here](https://github.com/filecoin-project/lotus/discussions/8334)!
  - chore: FVM: log when fvm is used([filecoin-project/lotus#8363](https://github.com/filecoin-project/lotus/pull/8363))
  - chore: ffi: the latest fvm release([filecoin-project/lotus#8382](https://github.com/filecoin-project/lotus/pull/8382))

### 🌟🌟🌟 Index Provider (Production Ready!) 🌟🌟🌟
- feat: markets: Integrate index ingest protocol and retrieve by any CID ([filecoin-project/lotus#7313](https://github.com/filecoin-project/lotus/pull/7313))

More and more useful data is being stored on Filecoin via deals made by clients to Storage Providers. The goal is that this content is discoverable when people need them. To achieve that goal, one of the projects [the Bedrock team](https://www.notion.so/pl-strflt/Bedrock-2e956d5d8143432080a1d84435ccf0ff) is working on is building an Indexer Ecosystem, a project that's focus on content addressing on Filecoin, then potentially have interoperability with IPFS in the future and eventually serve the retrieval market. The Indexer Ecosystem high level architecture overview diagram can be found [here](https://github.com/filecoin-project/storetheindex/blob/main/doc/indexer_ecosys.png) and a detailed write up about can be found [here](https://www.notion.so/pl-strflt/Introducing-Indexer-to-SP-90bf296794174a8281c121d4ce6747a0).

That being said, with this release, lotus Storage Providers can easily become an Index Provider and serve the Indexer Content Addressing System. Index Providers generate advertisements from the deals made by a storage provider and announces the data to the indexer nodes for further processing:
- To learn more about *what is an Index Provider and how to be an Index Provider*, read it [here](https://lotus.filecoin.io/storage-providers/operate/index-provider/) in lotus docuementation.
- An [one-off migration](https://lotus.filecoin.io/storage-providers/operate/index-provider/#first-time-migration) is needed in order for a Storage Provider to become an Index Provider and announce the proper formatted index. It's *highly recommended* for all Index Provider to do a [force bulk initialization](https://lotus.filecoin.io/storage-providers/configure/dagstore/#forcing-bulk-initialization) to enable index announcement on all existing deals.
  - Note that the Initialization places IO workload on your storage system. SP should set a proper `concurrency` based on your hardware or can stop/start initialization at their wish/convenience as proving deadlines approach and elapse, to avoid IOPS starvation or competition with window PoSt.
- After the first one-time migration, being an Index Provider barely puts any extra usage on SP's market system.
  - You can find the testing result by SPX fellows [here](https://github.com/filecoin-project/lotus/discussions/8087).

We recommend all Storage Providers that are serving deals in the Filecoin network to become a Index Provider, make the data you are storing discoverable for the retrieval market and retrieval clients!
- If you have any questions about becoming an index provider, or the indexer system in general, leave a comment [here](https://github.com/filecoin-project/lotus/discussions/8341).
- Follow the indexer project at https://github.com/filecoin-project/go-indexer-core.
- If you have any feature request or bug reports of running an index provider, create an issue in https://github.com/filecoin-project/index-provider.
- You may also join the #storetheindex channel in the Filecoin Slack to engage with the team & the community!

### ❗️❗️❗️ Dag Migration For New CAR index format in DagStore ❗️❗️❗️
The index provider leverages the latest CARv2 indexing format `MultihashIndexSorted`, which stores the multihash code as well as the digest of all CIDs in a CAR file. Thus, all Storage Providers SHOULD perform an one-off DAG mirgation to regenerate DagStore CARv2 indices. You have to do it to become an index provider, failing to do so may also impact your future deal making.
Follow the instruction [here](https://lotus.filecoin.io/storage-providers/operate/index-provider/) to perform the migration.

# 1.14.4 / 2022-03-03

This is a *highly recommended* optional release for storage providers that are doing snap deals. This fix the bug
that causes some snap deal sectors are stuck in `FinalizeReplicaUpdate`. In addition, SPs should be able to force
update sectors status without getting blocked by `normal shutdown of state machine`.

# v1.14.3 / 2022-02-28

This is an **optional** release, that includes a fix to properly register the `--really-do-it` flag for abort-upgrade.

# 1.14.2 / 2022-02-24

This is an **optional** release of lotus, that's had a couple more improvements w.r.t Snap experience for storage providers in preparation of the[upcoming OhSnap upgrade](https://github.com/filecoin-project/community/discussions/74?sort=new#discussioncomment-1922550).

Note that the network is STILL scheduled to upgrade to v15 on March 1st at 2022-03-01T15:00:00Z. All node operators, including storage providers, must upgrade to at least Lotus v1.14.0 before that time. Storage providers must update their daemons, miners, and worker(s).

Wanna know how to Snap your deal? Check [this](https://github.com/filecoin-project/lotus/discussions/8141) out!

## Bug Fixes
- fix lotus-bench for sealing jobs (#8173)
- fix:sealing:really-do-it flag for abort upgrade (#8181)
- fix:proving:post check sector handles snap deals replica faults (#8177)
- fix: sealing: missing file type (#8180)

## Others
- Retract force-pushed v1.14.0 to work around stale gomod caches (#8159): We originally tagged v1.14.0 off the wrong
  commit and fixed that by a force push, in which is a really bad practise since it messes up the go mod. Therefore,
  we want to retract it and users may use v1.14.1&^.

# 1.14.1 / 2022-02-18

This is an **optional** release of lotus, that fixes the incorrect *comment* of network v15 OhSnap upgrade **date**. Note the actual upgrade epoch in [v1.14.0](https://github.com/filecoin-project/lotus/releases/tag/v1.14.0) was correct.

# 1.14.0 / 2022-02-17

This is a MANDATORY release of Lotus that introduces [Filecoin network v15,
codenamed the OhSnap upgrade](https://github.com/filecoin-project/community/discussions/74?sort=new#discussioncomment-1922550).

The network is scheduled to upgrade to v15 on March 1st at 2022-03-01T15:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, and worker(s).

The OhSnap upgrade introduces the following FIPs, delivered in [actors v7](https://github.com/filecoin-project/specs-actors/releases/tag/v7.0.0):
- [FIP-0019 Snap Deals](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0019.md)
- [FIP-0028 Remove Datacap from Verified clients](https://github.com/filecoin-project/FIPs/pull/226)

It is recommended that storage providers download the new params before updating their node, miner, and workers. To do so:

- Download Lotus v1.14.0 or later
- run `make lotus-shed`
- run `./lotus-shed fetch-params` with the appropriate `proving-params` flag
- Upgrade the Lotus daemon and miner **when the previous step is complete**

All node operators, including storage providers, should be aware that a pre-migration will begin at 2022-03-01T13:30:00Z (90 minutes before the real upgrade). The pre-migration will take between 20 and 50 minutes, depending on hardware specs. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries.

# v1.13.2 /  2022-01-09

Lotus v1.13.2 is a *highly recommended* feature release with remarkable retrieval improvements, new features like
worker management, schedule enhancements and so on.

## Highlights
- 🚀🚀🚀Improve retrieval deal experience
  - Testing result with MinerX.3 shows the retrieval deal success rate has increased dramatically with faster transfer
    speed, you can join or follow along furthur performance testings [here](https://github.com/filecoin-project/lotus/discussions/7874). We recommend application developers to integrate with the new
    retrieval APIs to provide a better client experience.
  - 🌟🌟🌟 Reduce retrieval Time-To-First-Byte over 100x ([#7693](https://github.com/filecoin-project/lotus/pull/7693))
    - This change makes most free, small retrievals sub-second
  - 🌟🌟🌟 Partial retrieval ux improvements ([#7610](https://github.com/filecoin-project/lotus/pull/7610))
    - New retrieval commands for clients:
      - `lotus client ls`: retrieve and list desired object links
      - `lotus client cat`: retrieve and print the data from the network
    - 🌟🌟 The monolith `ClientRetrieve` method was broken into:
      - `ClientRetrieve` which retrieves data into the local repo (or into an IPFS node if ipfs integration is enabled)
      - `ClientRetrieveWait` which will wait for the retrieval to complete
      - `ClientExport` which will export data from the local node
      - Note: this change only applies to v1 API. v0 API remains unchanged.
    - 🌟 Support for full ipld selectors was added (for example making it possible to only retrieve list of directories in a deal, without fetching any file data)
      - To learn more, see [here](https://github.com/filecoin-project/lotus/blob/0523c946f984b22b3f5de8cc3003cc791389527e/api/types.go#L230-L264)
- 🚀🚀 Sealing scheduler enhancements ([#7703](https://github.com/filecoin-project/lotus/pull/7703),
  [#7269](https://github.com/filecoin-project/lotus/pull/7269)), [#7714](https://github.com/filecoin-project/lotus/pull/7714)
  - Workers are now aware of cgroup memory limits
  - Multiple tasks which use a GPU can be scheduled on a single worker
  - Workers can override default resource table through env vars
    - Default value list: https://gist.github.com/magik6k/c0e1c7cd73c1241a9acabc30bf469a43
- 🚀🚀 Sector storage groups ([#7453](https://github.com/filecoin-project/lotus/pull/7453))
  - Storage groups allow for better control of data flow between workers, for example, it makes it possible to define that data from PC1 on a given worker has to have it's PC2 step executed on the same worker
  - To set it up, follow the instructions under the `Sector Storage Group` section [here](https://lotus.filecoin.io/docs/storage-providers/seal-workers/#lotus-worker-co-location)

## New Features
- Add RLE dump code ([#7691](https://github.com/filecoin-project/lotus/pull/7691))
- Shed: Add a util to list miner faults ([#7605](https://github.com/filecoin-project/lotus/pull/7605))
- lotus-shed msg: Decode submessages/msig proposals ([#7639](https://github.com/filecoin-project/lotus/pull/7639))
- CLI: Add a lotus multisig cancel command ([#7645](https://github.com/filecoin-project/lotus/pull/7645))
- shed: simple wallet balancer util ([#7414](https://github.com/filecoin-project/lotus/pull/7414))
  - balancing token balance between multiple accounts

## Improvements
- Add verbose mode to `lotus-miner pieces list-cids` ([#7699](https://github.com/filecoin-project/lotus/pull/7699))
- retrieval: Only output matching nodes, MatchPath dagspec ([#7706](https://github.com/filecoin-project/lotus/pull/7706))

# v1.13.0 / 2021-10-18

Lotus v1.13.0 is a *highly recommended* feature release for all lotus users(i.e: storage providers, data brokers, application developers and so on) that supports the upcoming
[Network v14 Chocolate upgrade](https://github.com/filecoin-project/lotus/discussions/7431).
This feature release includes the latest functionalities and improvements, like data transfer rate-limiting for both storage and retrieval deals, proof v10 with CUDA support, etc. You can find more details in the Changelog below.

## Highlights
- Enable separate storage and retrieval transfer limits ([filecoin-project/lotus#7405](https://github.com/filecoin-project/lotus/pull/7405))
  - `SimultaneousTransfer` is now replaced by `SimultaneousTransfersForStorage` and `SimultaneousTransfersForRetrieval`, where users may set the amount of ongoing data transfer for storage and retrieval deals in parallel separately. The default value for both is set to 20.
  - If you are using the lotus client, these two configuration variables are under the `Client` section in `./lotus/config.toml`.
  - If you are a service provider, these two configuration variables should be set under the `Dealmaking` section in `/.lotusminer/config.toml`.
- Update proofs to v10.0.0 ([filecoin-project/lotus#7420](https://github.com/filecoin-project/lotus/pull/7420))
  - This version supports CUDA. To enable CUDA instead of openCL, build lotus with `FFI_USE_CUDA=1 FFI_BUILD_FROM_SOURCE=1 ...`.
  - You can find additional Nvidia driver installation instructions written by MinerX fellows [here](https://github.com/filecoin-project/lotus/discussions/7443#discussioncomment-1425274) and perf improvements result on PC2/C2/WindowPoSt computation on different profiles [here](https://github.com/filecoin-project/lotus/discussions/7443), most people observe a 30-50% decrease in computation time.

## New Features
- Feat/datamodel selector retrieval ([filecoin-project/lotus#6393](https://github.com/filecoin-project/lotus/pull/66393393))
  - This introduces a new RetrievalOrder-struct field and a CLI option that takes a string representation as understood by [https://pkg.go.dev/github.com/ipld/go-ipld-selector-text-lite#SelectorSpecFromPath](https://pkg.go.dev/github.com/ipld/go-ipld-selector-text-lite#SelectorSpecFromPath). This allows for partial retrieval of any sub-DAG of a deal provided the user knows the exact low-level shape of the deal contents.
    - For example, to retrieve the first entry of a UnixFS directory by executing, run `lotus client retrieve --miner f0XXXXX --datamodel-path-selector 'Links/0/Hash' bafyROOTCID ~/output`
- Expose storage stats on the metrics endpoint ([filecoin-project/lotus#7418](https://github.com/filecoin-project/lotus/pull/7418))
- feat: Catch panic to generate report and reraise ([filecoin-project/lotus#7341](https://github.com/filecoin-project/lotus/pull/7341))
  - Set `LOTUS_PANIC_REPORT_PATH` and `LOTUS_PANIC_JOURNAL_LOOKBACK` to get reports generated when a panic occurs on your daemon miner or workers.
- Add envconfig docs to the config ([filecoin-project/lotus#7412](https://github.com/filecoin-project/lotus/pull/7412))
  - You can now find supported env vars in [default-lotus-miner-config.toml](https://github.com/filecoin-project/lotus/blob/master/documentation/en/default-lotus-miner-config.toml).
- lotus shed: fr32 utils ([filecoin-project/lotus#7355](https://github.com/filecoin-project/lotus/pull/7355))
- Miner CLI: Allow trying to change owners of any miner actor ([filecoin-project/lotus#7328](https://github.com/filecoin-project/lotus/pull/7328))
- Add --unproven flag to the sectors list command ([filecoin-project/lotus#7308](https://github.com/filecoin-project/lotus/pull/7308))

## Improvements
- check for deal start epoch on SectorAddPieceToAny ([filecoin-project/lotus#7407](https://github.com/filecoin-project/lotus/pull/7407))
- Verify Voucher locks in VoucherValidUnlocked ([filecoin-project/lotus#5609](https://github.com/filecoin-project/lotus/pull/5609))
- Add more info to miner allinfo command ([filecoin-project/lotus#7384](https://github.com/filecoin-project/lotus/pull/7384))
- add `lotus-miner storage-deals list --format=json` with transfers ([filecoin-project/lotus#7312](https://github.com/filecoin-project/lotus/pull/7312))
- Fix formatting ([filecoin-project/lotus#7383](https://github.com/filecoin-project/lotus/pull/7383))
- GetCurrentDealInfo err: handle correctly err case ([filecoin-project/lotus#7346](https://github.com/filecoin-project/lotus/pull/7346))
- fix: Enforce verification key integrity check regardless of TRUST_PARAMS=1 ([filecoin-project/lotus#7327](https://github.com/filecoin-project/lotus/pull/7327))
- Show more deal states in miner info ([filecoin-project/lotus#7311](https://github.com/filecoin-project/lotus/pull/7311))
- Prep retrieval for selectors: no functional changes ([filecoin-project/lotus#7306](https://github.com/filecoin-project/lotus/pull/7306))
- Seed: improve helptext ([filecoin-project/lotus#7304](https://github.com/filecoin-project/lotus/pull/7304))
- Mempool: reduce size of sigValCache ([filecoin-project/lotus#7305](https://github.com/filecoin-project/lotus/pull/7305))
- Stop indirectly depending on deprecated github.com/prometheus/common ([filecoin-project/lotus#7474](https://github.com/filecoin-project/lotus/pull/7474))

# v1.11.2 / 2021-09-06

lotus v1.11.2 is a feature release that's **highly recommended ALL lotus users to upgrade**, including node operators,
storage providers and clients.

## Highlights
- 🌟🌟🌟 Introduce Dagstore and CARv2 for deal-making (#6671) ([filecoin-project/lotus#6671](https://github.com/filecoin-project/lotus/pull/6671))
  - **[lotus miner markets' Dagstore](https://lotus.filecoin.io/storage-providers/operate/dagstore/)** is a
    component of the `markets` subsystem in lotus-miner. It is a sharded store to hold large IPLD graphs efficiently,
    packaged as  location-transparent attachable CAR files and it replaces the former Badger staging blockstore. It
    is designed to provide high efficiency and throughput, and minimize resource utilization during deal-making operations.  
    The dagstore also leverages the indexing features of [CARv2](https://github.com/ipld/ipld/blob/master/specs/transport/car/carv2/index.md) to enable plan CAR files to act as read and write
    blockstores, which are served as the direct medium for data exchanges in markets for both storage and retrieval
    deal making without requiring intermediate buffers.
  - In the future, lotus will leverage and interact with Dagstore a lot for new features and improvements for deal
    making, therefore, it's highly recommended to lotus users to go through [Lotus Miner: About the markets dagstore](https://lotus.filecoin.io/storage-providers/operate/dagstore/) thoroughly to learn more about Dagstore's
    conceptual overview, terminology, directory structure, configuration and so on.
  - **Note**:
    - When you first start your lotus-miner or market subsystem with this release, a one-time/first-time **dagstore migration** will be triggered which replaces the former Badger staging blockstore with dagstore. We highly
      recommend storage providers to read this [section](https://lotus.filecoin.io/storage-providers/operate/dagstore/#first-time-migration) to learn more about
      what the process does, what to expect and how monitor it.
    - It is highly recommended to **wait all ongoing data transfer to finish or cancel inbound storage deals that
      are still transferring**, using the `lotus-miner data-transfers cancel` command before upgrade your market nodes. Reason being that the new dagstore changes attributes in the internal deal state objects, and the paths to the staging CARs where the deal data was being placed will be lost.
    - ‼️Having your dags initialized will become important in the near feature for you to provide a better storage
      and retrieval service. We'd suggest you to start [forced bulk initialization] soon if possible as this process
      places relatively high IP workload on your storage system and is better to be carried out gradually and over a
      longer timeframe. Read how to do properly perform a force bulk initialization [here](https://lotus.filecoin.io/storage-providers/operate/dagstore/#forcing-bulk-initialization).
    - ⏮ Rollback Alert(from v1.11.2-rcX to any version lower): If a storages deal is initiated with M1/v1.11.2(-rcX)
      release, it needs to get to the `StorageDealAwaitingPrecommit` state before you can do a version rollback or the markets process may panic.
  - 💙 **Special thanks to [MinerX fellows for testing and providing valuable feedbacks](https://github.com/filecoin-project/lotus/discussions/6852) for Dagstore in the past month!**
- 🌟🌟 rpcenc: Support reader redirect ([filecoin-project/lotus#6952](https://github.com/filecoin-project/lotus/pull/6952))
  - This allows market processes to send piece bytes directly to workers involved on `AddPiece`.
- Extending sectors: more practical and flexible tools ([filecoin-project/lotus#6097](https://github.com/filecoin-project/lotus/pull/6097))
  - `lotus-miner sectors check-expire` to inspect expiring sectors.
  - `lotus-miner sectors renew` for renewing expiring sectors, see the command help menu for customizable option
    like `extension`, `new-expiration` and so on.
- ‼️ MpoolReplaceCmd ( lotus mpool replace`) now takes FIL for fee-limit ([filecoin-project/lotus#6927](https://github.com/filecoin-project/lotus/pull/6927))
- Drop townhall/chainwatch ([filecoin-project/lotus#6912](https://github.com/filecoin-project/lotus/pull/6912))
  - ChainWatch is no longer supported by lotus.
- Configurable CC Sector Expiration ([filecoin-project/lotus#6803](https://github.com/filecoin-project/lotus/pull/6803))
  - Set `CommittedCapacitySectorLifetime` in lotus-miner/config.toml to specify the default expiration for a new CC
    sector, value must be between 180-540 days inclusive.

# 1.11.1 / 2021-08-16

> Note: for discussion about this release, please comment [here](https://github.com/filecoin-project/lotus/discussions/6904)

This is a  **highly recommended** but optional Lotus v1.11.1 release that introduces many deal making and datastore improvements and new features along with other bug fixes.

## Highlights
- ⭐️⭐️⭐️[**lotus-miner market subsystem**](https://lotus.filecoin.io/storage-providers/advanced-configurations/split-markets-miners/) is introduced in this release! It is **highly recommended** for storage providers to run markets processes on a separate machine! Doing so, only this machine needs to exposes public ports for deal making. This also means that the other miner operations can now be completely isolated by from the deal making processes and storage providers can stop and restarts the markets process without affecting an ongoing Winning/Window PoSt!
  - More details on the concepts, architecture and how to split the market process can be found [here](https://lotus.filecoin.io/storage-providers/advanced-configurations/split-markets-miners/#concepts).
  - Base on your system setup(running on separate machines, same machine and so on), please see the suggested practice by community members [here](https://github.com/filecoin-project/lotus/discussions/7047#discussion-3515335).
    - Note: if you are running lotus-worker on a different machine, you will need to set `MARKETS_API_INFO` for certain CLI to work properly. This will be improved by #7072.
  - Huge thanks to MinerX fellows for [helping testing the implementation, reporting the issues so they were fixed by now and providing feedbacks](https://github.com/filecoin-project/lotus/discussions/6861) to user docs in the past three weeks!
- Config for collateral from miner available balance ([filecoin-project/lotus#6629](https://github.com/filecoin-project/lotus/pull/6629))
  - Better control your sector collateral payment by setting `CollateralFromMinerBalance`, `AvailableBalanceBuffer` and `DisableCollateralFallback`.
    - `CollateralFromMinerBalance`:  whether to use available miner balance for sector collateral instead of sending it with each message, default is `false`.
    - `AvailableBalanceBuffer`: minimum available balance to keep in the miner actor before sending it with messages, default is 0FIL.
    - `DisableCollateralFallback`: whether to send collateral with messages even if there is no available balance in the miner actor, default is `false`.
- Config for deal publishing control addresses ([filecoin-project/lotus#6697](https://github.com/filecoin-project/lotus/pull/6697))
  - Set `DealPublishControl` to set the wallet used for sending `PublishStorageDeals` messages, instructions [here](https://lotus.filecoin.io/storage-providers/operate/addresses/#control-addresses).
- Config UX improvements ([filecoin-project/lotus#6848](https://github.com/filecoin-project/lotus/pull/6848))
  - You can now preview the default and updated node config by running `lotus/lotus-miner config default/updated`

# 1.10.1 / 2021-07-05

This is an optional but **highly recommended** release of Lotus for lotus miners that has many bug fixes and improvements based on the feedback we got from the community since HyperDrive.

## New Features
- commit batch: AggregateAboveBaseFee config #6650
  - `AggregateAboveBaseFee` is added to miner sealing configuration for setting the network base fee to start aggregating proofs. When the network base fee is lower than this value, the prove commits will be submitted individually via `ProveCommitSector`. According to the [Batch Incentive Alignment](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md#batch-incentive-alignment) introduced in FIP-0013, we recommend miners to set this value to 0.15 nanoFIL(which is the default value) to avoid unexpected aggregation fee in burn and enjoy the most benefits of aggregation!

## Bug Fixes
- storage: Fix FinalizeSector with sectors in storage paths #6652
- Fix tiny error in check-client-datacap #6664
- Fix: precommit_batch method used the wrong cfg.PreCommitBatchWait #6658
- to optimize the batchwait #6636
- fix getTicket: sector precommitted but expired case #6635
- handleSubmitCommitAggregate() exception handling #6595
- remove precommit check in handleCommitFailed #6634
- ensure agg fee is adequate
- fix: miner balance is not enough, so that ProveCommitAggregate msg exec failed #6623
- commit batch: Initialize the FailedSectors map #6647

# 1.10.0 / 2021-06-23

This is a mandatory release of Lotus that introduces Filecoin network v13, codenamed the HyperDrive upgrade. The
Filecoin mainnet will upgrade, which is epoch 892800, on 2021-06-30T22:00:00Z. The network upgrade introduces the
following FIPs:

- [FIP-0008](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0008.md): Add miner batched sector pre-commit method
- [FIP-0011](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0011.md): Remove reward auction from reporting consensus faults
- [FIP-0012](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0012.md): DataCap Top up for FIL+ Client Addresses
- [FIP-0013](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md): Add ProveCommitSectorAggregated method to reduce on-chain congestion
- [FIP-0015](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0015.md): Revert FIP-0009(Exempt Window PoSts from BaseFee burn)

Note that this release is built on top of Lotus v1.9.0. Enterprising users can use the `master` branch of Lotus to get the latest functionality, including all changes in this release candidate.

## Proof batching and aggregation

FIPs [0008](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0008.md) and [0013](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0013.md) combine to allow for a significant increase in the rate of onboarding storage on the Filecoin network. This aims to lead to more useful data being stored on the network, reduced network congestion, and lower network base fee.

**Check out the documentation [here]((https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#precommitsectorsbatch) for details on the new Lotus miner sealing config options, [here](https://lotus.filecoin.io/storage-providers/setup/configuration/#fees-section) for fee config options, and explanations of the new features.**

Note:
- We recommend to keep `PreCommitSectorsBatch` as 1.
- We recommend miners to set `PreCommitBatchWait` lower than 30 hours.
- We recommend miners to set a longer `CommitBatchSlack` and  `PreCommitBatchSlack` to prevent message failures
  due to expirations.

### Projected state tree growth

In order to validate the Hyperdrive changes, we wrote a simulation to seal as many sectors as quickly as possible, assuming the same number and mix of 32GiB and 64GiB miners as the current network.

Given these assumptions:

- We'd expect a network storage growth rate of around 530PiB per day. 😳 🎉 🥳 😅
- We'd expect network bandwidth dedicated to `SubmitWindowedPoSt` to grow by about 0.02% per day.
- We'd expect the [state-tree](https://spec.filecoin.io/#section-systems.filecoin_vm.state_tree) (and therefore [snapshot](https://lotus.filecoin.io/lotus/manage/chain-management/#lightweight-snapshot)) size to grow by 1.16GiB per day.
  - Nearly all of the state-tree growth is expected to come from new sector metadata.
- We'd expect the daily lotus datastore growth rate to increase by about 10-15% (from current ~21GiB/day).
  - Most "growth" of the lotus datastore is due to "churn", historical data that's no longer referenced by the latest state-tree.

### Future improvements

Various Lotus improvements are planned moving forward to mitigate the effects of the growing state tree size. The primary improvement is the [Lotus splitstore](https://github.com/filecoin-project/lotus/discussions/5788), which will soon be enabled by default. The feature allows for [online garbage collection](https://github.com/filecoin-project/lotus/issues/6577) for nodes that do not seek to maintain full chain and state history, thus eliminating the need for users to delete their datastores and sync from snapshots.

Other improvements including better compressed snapshots, faster pre-migrations, and improved chain exports are in the roadmap.

## WindowPost base fee burn

Included in the HyperDrive upgrade is [FIP-0015](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0015.md) which eliminates the special-case gas treatment of `SubmitWindowedPoSt` messages that was introduced in [FIP-0009](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0009.md). Although `SubmitWindowedPoSt` messages will be relatively cheap, thanks to the introduction of optimistic acceptance of these proofs in [FIP-0010](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0010.md), storage providers should pay attention to their `MaxWindowPoStGasFee` config option: too low and PoSts may not land on chain; too high and they may cost an exorbitant amount!

# 1.8.0 / 2021-04-05

This is a mandatory release of Lotus that upgrades the network to version 12, which introduces various performance improvements to the cron processing of the power actor. The network will upgrade at height 712320, which is 2021-04-29T06:00:00Z.

## Changes

- v4 specs-actors integration, nv12 migration (https://github.com/filecoin-project/lotus/pull/6116)

# 1.6.0 / 2021-04-05

This is a mandatory release of Lotus that upgrades the network to version 11, which implements [FIP-0014](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0014.md). The network will upgrade at height 665280, which is 2021-04-12T22:00:00Z.

## v1 sector extension CLI

This release also expands the `lotus-miner sectors extend` CLI, with a new option that automatically extends all extensible v1 sectors. The option can be run using `lotus-miner sectors extend --v1-sectors`.

- The `tolerance` flag can be passed to indicate what durations aren't "worth" extending. It defaults to one week, which means that sectors whose current lifetime's are within one week of the maximum possible lifetime will not be extended.

- The `expiration-cutoff` flag can be passed to skip sectors whose expiration is past a certain point from the current head. It defaults to infinity (no cutoff), but if, say, 28800 was specified, then only sectors expiring in the next 10 days would be extended (2880 epochs in 1 day).

## Changes

- Util for miners to extend all v1 sectors (https://github.com/filecoin-project/lotus/pull/5924)
- Upgrade the butterfly network (https://github.com/filecoin-project/lotus/pull/5929)
- Introduce the v11 network upgrade (https://github.com/filecoin-project/lotus/pull/5904)
- Debug mode: Make upgrade heights controllable by an envvar (https://github.com/filecoin-project/lotus/pull/5919)

# 1.5.3 / 2021-03-24

This is a patch release of Lotus that introduces small fixes to the Storage FSM.

## Changes

- storagefsm: Fix double unlock with ready WaitDeals sectors (https://github.com/filecoin-project/lotus/pull/5783)
- backupds: Allow larger values in write log (https://github.com/filecoin-project/lotus/pull/5776)
- storagefsm: Don't log the SectorRestart event (https://github.com/filecoin-project/lotus/pull/5779)

# 1.5.2 / 2021-03-11

This is an hotfix release of Lotus that fixes a critical bug introduced in v1.5.1 in the miner windowPoSt logic. This upgrade is only affecting miner nodes.

## Changes
- fix window post rand check (https://github.com/filecoin-project/lotus/pull/5773)
- wdpost: Always use head tipset to get randomness (https://github.com/filecoin-project/lotus/pull/5774)

# 1.5.1 / 2021-03-10

This is an optional release of Lotus that introduces an important fix to the WindowPoSt computation process. The change is to wait for some confidence before drawing beacon randomness for the proof. Without this, invalid proofs might be generated as the result of a null tipset.

## Splitstore

This release also introduces the splitstore, a new optional blockstore that segregates the monolithic blockstore into cold and hot regions. The hot region contains objects from the last 4-5 finalities plus all reachable objects from two finalities away. All other objects are moved to the cold region using a compaction process that executes every finality, once 5 finalities have elapsed.

The splitstore allows us to separate the two regions quite effectively, using two separate badger blockstores. The separation
means that the live working set is much smaller, which results in potentially significant performance improvements. In addition, it means that the coldstore can be moved to a separate (bigger, slower, cheaper) disk without loss of performance.

The design also allows us to use different implementations for the two blockstores; for example, an append-only blockstore could be used for coldstore and a faster memory mapped blockstore could be used for the hotstore (eg LMDB). We plan to experiment with these options in the future.

Once the splitstore has been enabled, the existing monolithic blockstore becomes the coldstore. On the first head change notification, the splitstore will warm up the hotstore by copying all reachable objects from the current tipset into the hotstore.  All new writes go into the hotstore, with the splitstore tracking the write epoch. Once 5 finalities have elapsed, and every finality thereafter, the splitstore compacts by moving cold objects into the coldstore. There is also experimental support for garbage collection, whereby nunreachable objects are simply discarded.

To enable the splitstore, add the following to config.toml:

```
[Chainstore]
  EnableSplitstore = true
```

## Highlights

Other highlights include:

- Improved deal data handling - now multiple deals can be adding to sectors in parallel
- Rewriten sector pledging - it now actually cares about max sealing sector limits
- Better handling for sectors stuck in the RecoverDealIDs state
- lotus-miner sectors extend command
- Optional configurable storage path size limit
- Config to disable owner/worker fallback from control addresses (useful when owner is a key on a hardware wallet)
- A write log for node metadata, which can be restored as a backup when the metadata leveldb becomes corrupted (e.g. when you run out of disk space / system crashes in some bad way)

# 1.5.0 / 2021-02-23

This is a mandatory release of Lotus that introduces the fifth upgrade to the Filecoin network. The network upgrade occurs at height 550321, before which time all nodes must have updated to this release (or later). At this height, [v3 specs-actors](https://github.com/filecoin-project/specs-actors/releases/tag/v3.0.0) will take effect, which in turn implements the following two FIPs:

- [FIP-0007 h/amt-v3](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0007.md) which improves the performance of the Filecoin HAMT and AMT.
- [FIP-0010 off-chain Window PoSt Verification](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0010.md) which reduces the gas consumption of `SubmitWindowedPoSt` messages significantly by optimistically accepting Window PoSt proofs without verification, and allowing them to be disputed later by off-chain verifiers.

Note that the integration of v3 actors was already completed in 1.4.2, this upgrade simply sets the epoch for the upgrade to occur.

## Disputer

FIP-0010 introduces the ability to dispute bad Window PoSts. Node operators are encouraged to run the new Lotus disputer alongside their Lotus daemons. For more information, see the announcement [here](https://github.com/filecoin-project/lotus/discussions/5617#discussioncomment-387333).

## Changes

- [#5341](https://github.com/filecoin-project/lotus/pull/5341)  Add a  `LOTUS_DISABLE_V3_ACTOR_MIGRATION` envvar
  - Setting this envvar to 1 disables the v3 actor migration, should only be used in the event of a failed migration

# 1.4.2 / 2021-02-17

This is a large, and highly recommended, optional release with new features and improvements for lotus miner and deal-making UX. The release also integrates [v3 specs-actors](https://github.com/filecoin-project/specs-actors/releases/tag/v3.0.0), which implements two FIPs:

- [FIP-0007 h/amt-v3](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0007.md) which improves the performance of the Filecoin HAMT and AMT.
- [FIP-0010 off-chain Window PoSt Verification](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0010.md) which reduces the gas consumption of `SubmitWindowedPoSt` messages significantly by optimistically accepting Window PoSt proofs without verification, and allowing them to be disputed later by off-chain verifiers.

Note that this release does NOT set an upgrade epoch for v3 actors to take effect. That will be done in the upcoming 1.5.0 release.

# 1.1.0 / 2020-10-20

This is a mandatory release that introduces the first post-liftoff upgrade to the Filecoin network. The changes that break consensus are an upgrade to specs-actors v2.2.0 at epoch 170000.

## Changes

- Introduce Network version 6 (https://github.com/filecoin-project/lotus/pull/4506)
- Update markets v1.0.0 (https://github.com/filecoin-project/lotus/pull/4505)

# 1.0.0 / 2020-10-19

It's 1.0.0! This is an optional release of Lotus that introduces some UX improvements to the 0.10 series.

This very small release is largely cosmetic, and intended to flag the code that the Filecoin mainnet was launched with.

## API changes

- `StateMsgGasCost` has been removed. The equivalent information can be gained by calling `StateReplay`.
- A `GasCost` field has been added to the `InvocResult` type, meaning detailed gas costs will be returned when calling `StateReplay`, `StateCompute`, and `StateCall`.
- The behaviour of `StateReplay` in response to an empty tipset key has been changed. Instead of simply using the heaviest tipset (which is almost guaranteed to be an unsuccessful replay), we search now search the chain for the tipset that included the message, and replay the message in that tipset (we fail if no such tipset is found).

## Changes

- Increase code coverage! (https://github.com/filecoin-project/lotus/pull/4410)

your hotfix PR is not a good idea. Find someone who has enough slept recently
enough to give you good code review, otherwise you'll end up quickly bumping
versions again.

- Fixed a bug in the mempool that was introduced in v0.5.2

# 0.5.2 / 2020-08-24

This is a hotfix release.

  differs from our mining base.

# 0.5.1 / 2020-08-24

The Space Race release!
This release contains the genesis car file and bootstrap peers for the space
race network.

Additionally, we included two small fixes to genesis creation:

- Correctly set t099 (burnt funds actor) to have valid account actor state

# 0.5.0 / 2020-08-20

This version of Lotus will be used for the incentivized testnet Space Race competition,
and can be considered mainnet-ready code. It includes some protocol
changes, upgrades of core dependencies, and various bugfixes and UX/performance improvements.

## Highlights

Among the highlights included in this release are:

- Gas changes: We implemented EIP-1559 and introduced real gas values.
- Deal-making: We now support "Committed Capacity" sectors, "fast-retrieval" deals,
  and the packing of multiple deals into a single sector.
- Renamed features: We renamed some of the binaries, environment variables, and default
  paths associated with a Lotus node.

### Gas changes

We made some significant changes to the mechanics of gas in this release.

#### Network fee

We implemented something similar to
[Ethereum's EIP-1559](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1559.md).
The `Message` structure had three changes:
- The `GasPrice` field has been removed
- A new `GasFeeCap` field has been added, which controls the maximum cost
  the sender incurs for the message
- A new `GasPremium` field has been added, which controls the reward a miner
  earns for including the message

A sender will never be charged more than `GasFeeCap * GasLimit`.
A miner will typically earn `GasPremium * GasLimit` as a reward.

The `Blockheader` structure has one new field, called `ParentBaseFee`.
Informally speaking,the `ParentBaseFee`
is increased when blocks are densely packed with messages, and decreased otherwise.

The `ParentBaseFee` is used when calculating how much a sender burns when executing a message. _Burning_ simply refers to sending attoFIL to a dedicated, unreachable account.
A message causes `ParentBaseFee * GasUsed` attoFIL to be burnt.

#### Real gas values

This release also includes our first "real" gas costs for primitive operations.
The costs were designed to account for both the _time_ that message execution takes,
as well as the _space_ a message adds to the state tree.

## Deal-making changes

There are three key changes to the deal-making process.

#### Committed Capacity sectors

Miners can now pledge "Committed Capacity" (CC) sectors, which are explicitly
stated as containing junk data, and must not include any deals. Miners can do this
to increase their storage power, and win block rewards from this pledged storage.

They can mark these sectors as "upgradable" with `lotus-miner sectors mark-for-upgrade`.
If the miner receives and accepts one or more storage deals, the sector that includes
those deals will _replace_ the CC sector. This is intended to maximize the amount of useful
storage on the Filecoin network.

#### Fast-retrieval deals

Clients can now include a `fast-retrieval` flag when proposing deals with storage miners.
If set to true, the miner will include an extra copy of the deal data. This
data can be quickly served in a retrieval deal, since it will not need to be unsealed.

#### Multiple deals per sector

Miners can now pack multiple deals into a single sector, so long as all the deals
fit into the sector capacity. This should increase the packing efficiency of miners.

### Renamed features

To improve the user experience, we updated several names to mainatin
standard prefixing, and to better reflect the meaning of the features being referenced.

In particular, the Lotus miner binary is now called `lotus-miner`, the default
path for miner data is now `~/.lotusminer`, and the environment variable
that sets the path for miner data is now `$LOTUS_MINER_PATH`. A full list of renamed
features can be found [here](https://github.com/filecoin-project/lotus/issues/2304).
