 # Lotus changelog

-# v1.23.2 / 2023-06-28
+# UNRELEASED

-This is a patch release on top of 1.23.1 containing the fix for https://github.com/filecoin-project/lotus/issues/10906
-This fixes the syncing issue seen by many node operators/SPs, usually when performing actions which would result in msgs staying in their mpool for longer periods of time (ex. PSD) resulting in these msgs being republished multiple times and possibly lowering your peer scores. Please refer to the above issue for more details.
-We'd recommend everyone to accept this fix to better overall network health
-
-## Improvements
- fix: pubsub: do not treat ErrExistingNonce as Reject
-
-
-# v1.23.1 / 2023-06-20
-
-This is an optional feature release of Lotus. This feature release includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.
-
-**☢️ Upgrade Warnings ☢️**
-
-If you are upgrading to this release candidate from Lotus v1.22.1, please make sure to read the upgrade warnings section in the [v1.23.0 release first.](https://github.com/filecoin-project/lotus/releases/tag/v1.23.0)
-
- *Storage providers:* The Lotus-Miner legacy-markets has been disbled by default in this feature release and will be removed in the near term future. Users are adviced to migrate to [Boost](https://boost.filecoin.io) or other SP markets systems.
-
-## Highlights
-
-**🛣 Execution Lanes 🛣**
-This feature release introduces VM Execution Lanes! Execution lanes efficiently divide the workload between system processes  (chainsync) and RPC requests. This way syncing the chain will not be at the mercy of responding to users' requests and RPC providers nodes should have less problems catching up.
-
-To take advantage of VM Execution Lanes, you need to set up two environment variables:
- `LOTUS_FVM_CONCURRENCY` - read more about how this value should be set to [here](https://lotus.filecoin.io/lotus/configure/ethereum-rpc/#environment-variables)
- `LOTUS_FVM_CONCURRENCY_RESERVED = 4` 
-
-**🧱 Aggregation / Batching fixes 🔨**
-
-Numerous aggregation and batching fixes has been included in the feature release. Large `ProveCommitAggregate` and `PreCommitBatching` messages that exceeds the block limit will now automatically be split into smaller messages when sent to the chain.
-
-Additionally we have added a new feature that staggers the amount of ProveCommit messages sent simulatanously to the chain if a storage provider has been aggregating many sectors in ProveCommitAggregate message, but at the time of publishing the BaseFee is below the aggregation threshold. This stagger feature prevents issues where some of the ProveCommit messages fail with the SysErrorOutOfGas message. You can tweak how many messages will be staggered per epoch by changing `MaxSectorProveCommitsSubmittedPerEpoch` in the [sealing section of the config.toml file.](https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#sealing-section)
-
-*NB:* While these fixes are great for the reliability of aggregation and batching on the Lotus side, it has been uncovered that aggregating ProveCommit messages for sectors containing verified deals are currently more expensive then single messages due to an issue on the actors side. We therefore do not reccomend our users to aggregate ProveCommit messages when doing verified deals until that issue has been resolved. You can follow the discussion on resolving the issue on the [actors side here.](https://github.com/filecoin-project/FIPs/discussions/689)
-
-**Unsealing CLI/API**
-
-This feature release adds a dedicated `lotus-miner sectors unseal` command and API, allowing you to unseal specific sealed sectors easily.

-# v1.23.0 / 2023-04-21
-
-This is the stable feature release for the upcoming MANDATORY network upgrade at `2023-04-27T13:00:00Z`, epoch `2809800`. This feature release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet, and includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.
-
-## ☢️ Upgrade Warnings ☢️
-
-Please read carefully through the **upgrade warnings** section if you are upgrading from a v1.20.X release, or the v1.22.0 release. If you are upgrading from a v1.21.0-rcX these warnings should be familiar to you.
-
- Starting from this release, the SplitStore feature is automatically activated on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the `EnableSplitstore` option in your `config.toml` file. To enable SplitStore, set `EnableSplitstore=true`, and to disable it, set `EnableSplitstore=false`. **It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!**
- This feature release requires a **minimum Go version of v1.19.7 or higher to successfully build Lotus**. Additionally, Go version v1.20 and higher is now also supported.
- **Storage Providers:** The proofs libraries now have CUDA enabled by default, which requires you to install (CUDA)[https://lotus.filecoin.io/tutorials/lotus-miner/cuda/] if you haven't already done so. If you prefer to use OpenCL on your GPUs instead, you can use the `FFI_USE_OPENCL=1` flag when building from source. On the other hand, if you want to disable GPUs altogether, you can use the `FFI_NO_GPU=1` environment variable when building from source.
- **Storage Providers:** The `lotus-miner sectors extend` command has been refactored to the functionality of `lotus-miner sectors renew`.
- **Exchanges/Node operators/RPC-providers::** Execution traces (returned from `lotus state exec-trace`, `lotus state replay`, etc.), has changed to account for changes introduced by the by the FVM. **Please make sure to read the `Execution trace format change` section carefully, as these are interface breaking changes**
- **Syncing issues:** If you have been struggling with syncing issues in normal operations you can try to adjust the amount of threads used for more concurrent FMV execution through via the `LOTUS_FVM_CONCURRENCY` enviroment variable. It is set to 4 threads by default. Recommended formula for concurrency == YOUR_RAM/4 , but max during a network upgrade is 24. If you are a Storage Provider and are pushing many messages within a short period of time, exporting `LOTUS_SKIP_APPLY_TS_MESSAGE_CALL_WITH_GAS=1` will also help with keeping in sync.
- **Catching up from a Snapshot:** Users have noticed that catching up sync from a snapshot is taking a lot longer these day. This is largely related to the built-in market actor consuming a lot of computational demand for block validation. A FIP for a short-term mitigation for this is currently in Last Call and will be included network version 19 upgrade if accepted. You [can read the FIP here.](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md)

-**SplitStore**
-
-This feature release introduces numerous improvements and fixes to tackle SplitStore related issues that has been reported. With this feature release SplitStore is automatically activated by default on new nodes. However, for existing Lotus users, you need to explicitly configure SplitStore by uncommenting the `EnableSplitstore` option in your `config.toml` file. To enable SplitStore, set `EnableSplitstore=true`, and to disable it, set `EnableSplitstore=false`. **It's important to note that your Lotus node will not start unless this configuration is properly set. Set it to false if you are running a full archival node!**
-
-SplitStore also has some new configuration settings that you can set in your config.toml file:
- `HotstoreMaxSpaceTarget` suggests the max allowed space (in bytes) the hotstore can take.
- `HotstoreMaxSpaceThreshold` a moving GC will be triggered when total moving size exceeds this threshold (in bytes).
- `HotstoreMaxSpaceSafetyBuffer` a safety buffer to prevent moving GC from an overflowing disk.
-
-The SplitStore also has two new commands:
-
- `lotus chain prune hot` is a much less resource-intensive GC and is best suited for situations where you don't have the spare disk space for a full GC.
- `lotus chain prune hot-moving` will run a full moving garbage collection of the hotstore. This commands create a new hotstore before deleting the old one so you need working room in the hotstore directory. The current size of a fully GC'd hotstore is around 295 GiB so you need to make sure you have at least that available.
-
-You can read more about the new SplitStore commands in [the documentation](https://lotus.filecoin.io/lotus/configure/splitstore/#manual-chain-store-garbage-collection).
-
-**RPC API improvements**
-
-This feature release includes all the RPC API improvements made in the Lotus v1.20.x patch releases. It includes an updated FFI that sets the FVM parallelism to 4 by default.
-
-Node operators with higher memory specs can experiment with setting LOTUS_FVM_CONCURRENCY to higher values, up to 48, to allow for more concurrent FVM execution.
-
-**Experimental scheduler assigners**
-
-In this release there are four new expirmental scheduler assigners:
-
- The `experiment-spread-qcount` - similar to the spread assigner but also takes into account task counts which are in running/preparing/queued states.
- The `experiment-spread-tasks` - similar to the spread assigner, but counts running tasks on a per-task-type basis
- The `experiment-spread-tasks-qcount` -  similar to the spread assigner, but also takes into account task counts which are in running/preparing/queued states, as well as counting running tasks on a per-task-type basis. Check the results for this assigner on ([storage-only lotus-workers here](https://github.com/filecoin-project/lotus/issues/8566#issuecomment-1446978856)).
- The `experiment-random` - In each schedule loop the assinger figures a set of all workers which can handle the task and then picks a random one. Check the results for this assigner on ([storage-only lotus-workers here](https://github.com/filecoin-project/lotus/issues/8566#issuecomment-1447064218)).
-
-**Graceful shutdown of lotus-workers**
-We have cleaned up some commands in the `lotus-worker` to make it less confusing how to gracefully shutting down a `lotus-worker` while there are incoming sealing tasks in the pipeline. To shut down a `lotus-worker` gracefully:
-
-1. `lotus-worker tasks disable --all` and wait for the worker to finish processing its current tasks.
-2. `lotus-worker stop` to detach it and do maintenance/upgrades.
-
-**CLI speedups**
-
-The `lotus-miner sector list` is now running in parallel - which should speed up the process from anywhere between 2x-10x+. You can tune it additionally with the `check-parallelism` option in the command. The `Lotus-Miner info` command also has a large speed improvement, as calls to the lotus legacy market has been removed.

-# v1.22.1 / 2023-04-23
-
-## Important Notice
-
-This is a MANDATORY hotfix release that fixes a consensus-critical bug that was in v1.22.0 -- the necessary fix is https://github.com/filecoin-project/ref-fvm/pull/1750 and it is integrated into lotus via https://github.com/filecoin-project/lotus/pull/10735.
-You can NOT use 1.22.0 for the nv19 upgrade, you MUST be on 1.22.1 or higher.
-
-## About This Release
-
-This is the stable release of Lotus v1.22.1 for the upcoming MANDATORY network upgrade at `2023-04-27T13:00:00Z`, epoch `2809800`. This release delivers the nv19 Lighting and nv20 Thunder network upgrade for mainnet.
-
-Note that you must be on a go version higher than Go 1.18.8, but lower than Go v1.20.0. We would recommend Go 1.19.7.
-
-The Lighting and Thunder upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors [v11.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0-rc2)):
-
- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - Fallback method handler for multisig actor
-
-## Expedited nv19 Lightning ⚡️ rollout
-
-In light of the recent degraded chain quality on the mainnet [an expedited nv19 upgrade has been proposed and accepted](https://github.com/filecoin-project/core-devs/discussions/123#discussioncomment-5642909) to roll out the market cron mitigation ([FIP0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md)) that will improve block validation times, and with that the delay in block production that is causing a decrease in the chain quality currently.
-
-With this expedited roll out we want to inform you of some **key changes and important dates:**
-
- Accelerate the nv19-upgrade on **mainnet** from May 11th to **April 27th**.
- Derisk nv19 by descoping the sector info migration, activation epoch fixes and drop [[FIP0052 - Extend sector/deal max duration to 3.5 year.](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
-  - By descoping these changes we can greatly derisk the network upgrade itself by removing a heavy migration that could cause instability for storage providers and node operators during the network upgrade.
- Increase the rollover period for [[FIP0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md) from 1 week to 3 weeks on mainnet. The rollover period is the duration between nv19 and nv20 which both old proofs (v1) and the new proofs (v1_1) proofs will be accepted by the network.
-
-The Lighting and Thunder upgrade now implements the following Filecoin Improvement Proposals (FIPs), delivered by builtin-actors v11 (see actors [v11.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v11.0.0)):
-
- [FIP 0060](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0060.md) - Thirty day market deal maintenance interval
- [FIP 0061](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0061.md) - WindowPoSt grindability fix
- [FIP 0062](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0062.md) - Fallback method handler for multisig actor

-### Dependencies
-github.com/filecoin-project/go-state-types (v0.11.0-rc1 -> v0.11.1):
-
-# v1.20.4 / 2023-03-17
-
-This is a patch release intended to alleviate performance issues reported by some users since the nv18 upgrade. 
-The primary change is to update the FFI to allow for FVM parallelism of 4 by default, and make this user-configurable.
-through the `LOTUS_FVM_CONCURRENCY` env var. 
-
-Users with higher memory specs can experiment with setting `LOTUS_FVM_CONCURRENCY` to higher values, up to 48, to allow for more concurrent FVM execution.
