This is the third release candidate of the upcoming MANDATORY Lotus v1.26.0 release, which will deliver the Filecoin network version 22, codenamed Dragon 🐉. This third release candidate brings in multiple storage provider fixes, and cleanups for issues encountered during testing in the Calibration network.
**This release candidate only has the calibration network to upgrade set, which happened at epoch 1427974, 2024-03-11T14:00:00Z. This release does NOT set the mainnet upgrade epoch, which will be updated in the final release.**
- [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)
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.
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/)
## New features
- feat: api: new verified registry methods to get all allocations and claims (#11631) ([filecoin-project/lotus#11631](https://github.com/filecoin-project/lotus/pull/11631))
- feat: sealing: Support nv22 DDO features in the sealing pipeline (#11226) ([filecoin-project/lotus#11226](https://github.com/filecoin-project/lotus/pull/11226))
- 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))
- fix: beacon: validate drand change at nv16 correctly ([filecoin-project/lotus#11690](https://github.com/filecoin-project/lotus/pull/11690))
- fix: events: properly disable actor events API via cfg ([filecoin-project/lotus#11701](https://github.com/filecoin-project/lotus/pull/11701))
- fix: events: Enable event storage config for Actor events as well ([filecoin-project/lotus#11712](https://github.com/filecoin-project/lotus/pull/11712))
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.
[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.
`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.
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.
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.
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
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.
The feature release ships the alpha release of the new Lotus-Provider binary, together with its initial features - High Availability of 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.
- 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.
-`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)**
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/).

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))
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 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).
- 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.
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.
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.

This is the stable release for the upcoming **MANDATORY** Filecoin network upgrade v21, codenamed Watermelon 🍉, at **epoch 3469380 - 2023-12-12T13:30:00Z**.
Full list of the other protocol improvements we are delivering can be found [here](https://github.com/filecoin-project/core-devs/blob/master/Network%20Upgrades/v21.md).
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:
There is a new protocol limit on how many partition could be submited in one PoSt - if you have any customized tooling for batching PoSts, please update accordingly.
- Implement and support [FIP0052: Increase Max Sector Commitment to 3.5 years](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
- fix: docs: Update SectorLifetime to be in line with FIP-0052 ([filecoin-project/lotus#11314](https://github.com/filecoin-project/lotus/pull/11314))
- Implement and support [FIP0059: Synthetic PoRep](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0059.md) - Check out the [Lotus documentation for Synthetic PoRep](https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#synthetic-porep).
The [Forest team](https://filecoinproject.slack.com/archives/C029LPZ5N73) at Chainsafe has launched a brand new lightweight snapshot service that is backed up by forest nodes! This is a great alternative service along with the fil-infra one, and it is compatible with lotus! We recommend lotus users to check it out [here](https://docs.filecoin.io/networks/mainnet#resources)!
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.
- [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/)
- 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.

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
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.
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.
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)
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)
- feat: sealing: Split PCA/PCB batches if gas used exceeds block limit ([filecoin-project/lotus#10647](https://github.com/filecoin-project/lotus/pull/10647))
- Staggers the amount of ProveCommit messages sent simultanously if a storage provider has been aggregating many message, but at the moment of publishing the BaseFee is below the threshold for aggregation to prevent unwanted SysErrorOutOfGas issues.
- MVP of a message index that allows us to accelrate StateSearchMessage and related functionality, and eventually accelerate critical chain calls (follow up).

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.
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.
- **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)
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).
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.
-`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).
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.
- 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.
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.

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.
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 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
- Correct epoch to match specified date (commit: [a28fcea](https://github.com/filecoin-project/lotus/commit/a28fceaa559b6c7e1b5df09383af56a5c2f51caa))
- Fast butterfly migration to validate migration (commit: [37a0dca](https://github.com/filecoin-project/lotus/commit/37a0dca11ebfadebad3920a337b4f1b2fba08a7b))

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.

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)):
- [FIP-0055](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0055.md): Supporting Ethereum Accounts, Addresses, and Transactions
- [FIP-0057](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0057.md): Update gas charging schedule and system limits for FEVM
## 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).
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:
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/).
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` .
[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.
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).
- 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: 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))
- 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))
- Adds the beneficiary address to the `lotus-miner actor control list` output.
- 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.

As mentioned in [lotus v1.17.0 release notes](https://github.com/filecoin-project/lotus/releases/tag/v1.17.0), markets related features, enhancements and fixes is now lower priority for Lotus. We recommend our users to migrate to other deal making focused software, like [boost](https://boost.filecoin.io/) as soon as possible. That being said, the lotus maintainers will be:
- Lotus maintainers will stop supporting lotus-market subcomponent/**storage** deal making related issues or enhancements on Jan 31, 2023.
- In Q2 2023, we will be deprecating/removing lotus-market related code from this repository.
If you have any questions or concerns, please raise them in [Lotus discussion](https://github.com/filecoin-project/lotus/discussions/categories/market)!
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).
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
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.**

-`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!
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)
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:
- feat: add API methods to get allocations and claims ([filecoin-project/lotus#9437](https://github.com/filecoin-project/lotus/pull/9437))

- chore: actors: Allow builtin-actors to return a map of methods (#9342) ([filecoin-project/lotus#9342](https://github.com/filecoin-project/lotus/pull/9342))
As mentioned in [lotus v1.17.0 release notes](https://github.com/filecoin-project/lotus/releases/tag/v1.17.0), markets related features, enhancements and fixes is now lower priority for Lotus. We recommend our users to migrate to other deal making focused software, like [boost](https://boost.filecoin.io/) as soon as possible. That being said, the lotus maintainers will be:
- Lotus maintainers will stop supporting lotus-market subcomponent/**storage** deal making related issues or enhancements on Jan 31, 2023.

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!**
- 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.
- The default propagation delay is raised to 10 seconds from 6 seconds. Ability to set it yourself with the `PROPAGATION_DELAY_SECS` environment variable.
- 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.
- 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

PSA: Markets related features, enhancements and fixes is now lower priority for Lotus, and is going to be in the hands of [Boost](https://boost.filecoin.io), built by the amazing [Bedrock team](https://www.notion.so/pl-strflt/Bedrock-2e956d5d8143432080a1d84435ccf0ff). You can find Lotus mission scope [here](https://www.notion.so/Lotus-8352bbb6c321431abd8790a7a3401ed3#805c645f592840ad893c272723362d3d)
- feat: worker: lotus-worker run --no-default ([filecoin-project/lotus#8672](https://github.com/filecoin-project/lotus/pull/8672))

This is an OPTIONAL PATCH releases for storage providers who have failed to publish `SubmitWindowedPoSt` due to out of gas error. The error log looks like `/wdpost_run.go:xxx estimating gas {"error": "estimating gas used: message execution failed: exit SysErrOutOfGas(7)...`.
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):,
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.
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`.
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.
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`.

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.
‼️️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).
- 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:
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.

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!!
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)!
- 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.
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.

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).
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.
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):
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.
- feat: #7880 gas: add gas charge for VerifyReplicaUpdate ([#7897](https://github.com/filecoin-project/lotus/pull/7897))
- enhancement: sectors: disable existing cc upgrade path 2 days before the upgrade epoch ([#7900](https://github.com/filecoin-project/lotus/pull/7900))
- updating to new datastore/blockstore code with contexts ([#7646](https://github.com/filecoin-project/lotus/pull/7646))
- reorder transfer checks so as to ensure sending 2B FIL to yourself fails if you don't have that amount ([#7637](https://github.com/filecoin-project/lotus/pull/7637))
- 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
-`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)
- 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)
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
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.
-`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`.
- 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.
- 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`
- 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).
- 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))
This is a mandatory release of Lotus that introduces [Filecoin Network v14](https://github.com/filecoin-project/community/discussions/74#discussioncomment-1398542), codenamed the Chocolate upgrade. The Filecoin mainnet will upgrade at epoch 1231620, on 2021-10-26T13:30:00Z.
- [FIP-0026](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0026.md): Extend sector faulty period from 2 weeks to 6 weeks
Note that this release is built on top of lotus v1.11.3. Enterprising users like storage providers, data brokers and others are recommended to use lotus v1.13.0 for latest new features, improvements and bug fixes.

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.
- ⭐️⭐️⭐️[**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!
- Better control your sector collateral payment by setting `CollateralFromMinerBalance`, `AvailableBalanceBuffer` and `DisableCollateralFallback`.

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.
-`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!

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.
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.**
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.
- 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.
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.
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!
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.
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.
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).
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)
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.
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)
## Changes
- avoid use mp.cfg directly to avoid race (https://github.com/filecoin-project/lotus/pull/5350)
- Show replacing message CID is state search-msg cli (https://github.com/filecoin-project/lotus/pull/5656)

- Remove sectors with all deals expired in RecoverDealIDs (https://github.com/filecoin-project/lotus/pull/5658)
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).

- Updated [markets](https://github.com/filecoin-project/go-fil-markets/releases/tag/v1.0.4) to v1.0.4, which reduces failures due to reorgs (https://github.com/filecoin-project/lotus/pull/4730) and uses the newly refactored fund manager (https://github.com/filecoin-project/lotus/pull/4736)
## Changes
#### Core Lotus
- polish: add Equals method to MinerInfo shim (https://github.com/filecoin-project/lotus/pull/4604)
This is a patch release of Lotus that builds on the fixes involving worker keys that was introduced in v1.1.1. Miners and node operators should update to this release as soon as possible in order to ensure their blocks are propagated and validated.
This is a patch release of Lotus that addresses some issues caused by when miners change their worker keys. Miners and node operators should update to this release as soon as possible, especially any miner who has changed their worker key recently.
## Changes
- Miner finder for interactive client deal CLI (https://github.com/filecoin-project/lotus/pull/4504)
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)
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).
This is an optional release of Lotus that updates markets to 0.9.1, which fixes an issue affecting deals that were mid-transfer when the node was upgraded to 0.9.0. This release also includes some tweaks to default gas values and minor performance improvements.

- Lotus-pcr: Limit the fee cap of messages we will process, refund gas fees for windowed post and storage deals (https://github.com/filecoin-project/lotus/pull/4198)
This optional release of Lotus introduces a new version of markets which switches to CBOR-map encodings, and allows datastore migrations. The release also introduces several improvements to the mining process, a few performance optimizations, and a battery of UX additions and enhancements.
This consensus-breaking release of Lotus introduces an upgrade to the network. The changes that break consensus are:
- Upgrading to specs-actors v0.9.11, which reduces WindowPoSt faults per [FIP 0002](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0002.md) to reduce cost for honest miners with occasional faults (see https://github.com/filecoin-project/specs-actors/pull/1181)
- Revisions to some cryptoeconomics and network params
This release also updates go-fil-markets to fix an incompatibility issue between v0.7.2 and earlier versions.
This optional release of Lotus introduces a major refactor around how a Lotus node interacts with code from the specs-actors repo. We now use interfaces to read the state of actors, which is required to be able to reason about different versions of actors code at the same time.
- Add basic deal stats api server for spacerace slingshot (https://github.com/filecoin-project/lotus/pull/3963)
- When doing `sectors update-state`, show a list of existing states if user inputs an invalid one (https://github.com/filecoin-project/lotus/pull/3944)
This optional release of Lotus introduces some critical fixes to the window PoSt process. It also upgrades some core dependencies, and introduces many improvements to the mining process, deal-making cycle, and overall User Experience.
This consensus-breaking release of Lotus is designed to test a network upgrade on the space race testnet. The changes that break consensus are:
- Upgrading the Drand network used from the test Drand network to the League of Entropy main drand network. This is the same Drand network that will be used in the Filecoin mainnet.
- Upgrading to specs-actors v0.9.8, which adds a new method to the Multisig actor.
This release introduces some critical fixes to message selection and gas estimation logic. It also adds the ability for nodes to mark a certain tipset as checkpointed, as well as various minor improvements and bugfixes.
This consensus-breaking release of Lotus is designed to test a network upgrade on the space race testnet. The changes that break consensus are:
- Tweaking of some cryptoecon parameters in specs-actors 0.9.7 (https://github.com/filecoin-project/specs-actors/releases/tag/v0.9.7)
- Rebalancing FIL distribution to make testnet FIL scarce, which prevents base fee spikes and sets better expectations for mainnet
This release also introduces many improvements to Lotus! Among them are a new version of go-fil-markets that supports non-blocking retrieval, various spam reduction measures in the messagepool and p2p logic, and UX improvements to payment channels, dealmaking, and state inspection.
- Make chain export ~1000x times faster (https://github.com/filecoin-project/lotus/pull/3533)

This patch includes some bugfixes to the sector sealing process, and updates go-fil-markets. It also improves the performance of blocksync, adds a method to export chain state trees, and improves chainwatch.
## Changes
- Upgrade markets to v0.5.9 (https://github.com/filecoin-project/lotus/pull/3496)
- Improve blocksync to load fewer messages: (https://github.com/filecoin-project/lotus/pull/3494)
- Fix a panic in the ffi-wrapper's `ReadPiece` (https://github.com/filecoin-project/lotus/pull/3492/files)
- Fix a deadlock in the sealing scheduler (https://github.com/filecoin-project/lotus/pull/3489)
- Add test vectors for tipset tests (https://github.com/filecoin-project/lotus/pull/3485/files)
- Improve the advance-block debug command (https://github.com/filecoin-project/lotus/pull/3476)
- Add toggle for message processing to Lotus PCR (https://github.com/filecoin-project/lotus/pull/3470)
- Allow exporting recent chain state trees (https://github.com/filecoin-project/lotus/pull/3463)
- Remove height from chain rand (https://github.com/filecoin-project/lotus/pull/3458)
- Disable GC on chain badger datastore (https://github.com/filecoin-project/lotus/pull/3457)
- Account for `GasPremium` in `GasEstimateFeeCap` (https://github.com/filecoin-project/lotus/pull/3456)
- Update go-libp2p-pubsub to `master` (https://github.com/filecoin-project/lotus/pull/3455)
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.
