This is an optional feature release of Lotus. This feature release includes the production ready SplitStore feature, the experimental Lotus node cluster feature, as well as numerous enhancments and bugfixes.
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.
In this release, splitstore is enabled by default with `discard` mode. The `EnableColdStoreAutoPrune=` configuration is being deprecated in this release, as there is only ever one compaction running.
There are more configuration one may set, you can read the full documentation about the SplitStoreV2 here: https://lotus.filecoin.io/lotus/configure/splitstore/.
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.
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 ✅
- 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: 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))
- 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: 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))
- Creating a new WaitMutable state - now if the deadline is open and the sectors are trying finalize they will wait on the worker until the deadline has closed. Important to note that they will not finalize as soon as the deadline closes, they will wait 1h before continuing. Fixes the previous issue where upgraded Snap-sectors for an open deadline cause a lot of `error-messages` and `p_aux` issues
- fix: cli: add beneficiary info to lotus-miner actor control list ([filecoin-project/lotus#9632](https://github.com/filecoin-project/lotus/pull/9632))
- fix: post worker sched: Don't check worker session in a busy loop ([filecoin-project/lotus#9495](https://github.com/filecoin-project/lotus/pull/9495))
- Fixes a looping pattern which could result in a flood of requests between `lotus-miner`<->`lotus-worker`, potentially exhausting resources needed to make http requests, that lead to all sorts of random RPC-related issues.
- fix: miner: init miner's with 32GiB sectors by default ([filecoin-project/lotus#9364](https://github.com/filecoin-project/lotus/pull/9364))
- Makes the `lotus-miner init` defualt to 32GiB sectors.
- fix: store identity CIDs in CARs for online deals (#749) ([filecoin-project/go-fil-markets#749](https://github.com/filecoin-project/go-fil-markets/pull/749))
- update ffi to 280c4f8b94fd46dc (#9608) ([filecoin-project/lotus#9608](https://github.com/filecoin-project/lotus/pull/9608))
- fix: tvx: make it work with the FVM ([filecoin-project/lotus#9604](https://github.com/filecoin-project/lotus/pull/9604))
- fix: autobatch: remove potential deadlock when a block is missing ([filecoin-project/lotus#9602](https://github.com/filecoin-project/lotus/pull/9602))
- _ci_: Have apt-get wait until it can get a lock in packer builds ([filecoin-project/lotus#9534](https://github.com/filecoin-project/lotus/pull/9534))
- _ci_: Fix failing Digital Ocean and Amazon Machine Image release process ([filecoin-project/lotus#9425](https://github.com/filecoin-project/lotus/pull/9425))
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 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.**
- [FIP0029 Beneficiary Address for Storage Providers](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0029.md): step towards better lending market for SP
- [FIP0034 Fix PreCommit Deposit Independent of Sector Content](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0034.md): resolves a significant weakening of Filecoin PoRep’s security guarantees
- ❗Pre-commit deposit will be calculated as the 20-day projection of expected reward earned by a sector with **a sector quality of 10 (i.e. full of verified deals)**, regardless of sector content. The Initial Pledge value, due when the sector is proven, is left **unchanged**.
- [FIP0041 Forward Compatibility for PreCommit](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0041.md): enables a cleaner and easier transition to Programmable Storage Markets
- [FIP0044 Standard Message Authentication](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0044.md): enable metadata authentication for user defined actor
- [FIP0045 Decoupling Fil+ from Marketplace](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0045.md): DataCap and the 10x QAP is now only associated with how long DATA is wanted to be stored on the network.
- This is a transitional state to enabling far more efficient and dynamic storage markets on Filecoin network in the future.
- ⭐️ First Fungible Token Contract - Datacap Actor, on Filecoin! ([fungible token standard](https://github.com/filecoin-project/FIPs/blob/master/FRCs/frc-0046.md), [token contract library](https://github.com/helix-onchain/filecoin/tree/5455f4f831e0f3f20005a9a789623d7ad6dada15/frc46_token)).
- For storage deal participants (clients and storage providers):
-`PublishStorageDeals`/`ProveCommit(Aggregate)`/`ProveReplicaUpdates` message that includes verified deals will see a gas usage increase, more details can be found [here](https://github.com/filecoin-project/FIPs/blob/385f069b3b146c5fef4fdc1109a0e2f35f399e48/FIPS/fip-0045.md?plain=1#L784)
-`Term` is introduced for defining how long the DataCap is assigned to a piece of data. Anyone who cares about that piece of data may extend the _term_, which incentives SPs to store the data longer on the network without a new deal/resealing.
- There is no more diluted verified deal QAP due to deal/sector space time for new sectors that contains verified deals after this upgrade.
- SPs may enjoy 90 days of extra QAP than deal duration by default, given `term_max` is always `deal duration + 90 days`.
❗ We highly recommend all lotus users, especially storage providers, developers and clients to read the FIPs in detail to understand the protocol changes and potential impact to network participants!
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))

- feat: API: support typed errors over RPC ([filecoin-project/lotus#9061](https://github.com/filecoin-project/lotus/pull/9061))
- 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
- feat: message: Add retries to mpool push message from lotus-miner ([filecoin-project/lotus#9177](https://github.com/filecoin-project/lotus/pull/9177))

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))
- Makes it very easy to spin up workers that make the compute tasks opt-in, instead of the default opt-out. Also makes it very easy to create storage-only workers. [Link to the documentation](https://lotus.filecoin.io/storage-providers/seal-workers/seal-workers/#run-the-worker)
- feat: sched: Per worker concurrent task count limits ([filecoin-project/lotus#8725](https://github.com/filecoin-project/lotus/pull/8725))
- Set the maximum number of tasks running it parallel on workers by exporting env-variables: `[short task type]_[sector size]_MAX_CONCURRENT=[limit]`. [Link to documentation](https://lotus.filecoin.io/storage-providers/seal-workers/seal-workers/#limit-tasks-run-in-parallel)
- Introduce a new simpler worker assigning logic which will attempt to assign tasks to as many workers as possible and ignore worker utilization. [Link to documentation](https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#worker-assigning-logic)
- Allows you to only test the performance of a single task. [Read the documentation](https://lotus.filecoin.io/storage-providers/operate/benchmarks/#single-task-benchmark).

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)

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))

The dagstore also leverages the indexing features of [CARv2](https://github.com/ipld/ipld/blob/master/specs/transport/car/carv2/index.md) to enable plan CAR files to act as read and write
blockstores, which are served as the direct medium for data exchanges in markets for both storage and retrieval

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`.
-`CollateralFromMinerBalance`: whether to use available miner balance for sector collateral instead of sending it with each message, default is `false`.
-`AvailableBalanceBuffer`: minimum available balance to keep in the miner actor before sending it with messages, default is 0FIL.
-`DisableCollateralFallback`: whether to send collateral with messages even if there is no available balance in the miner actor, default is `false`.
- Config for deal publishing control addresses ([filecoin-project/lotus#6697](https://github.com/filecoin-project/lotus/pull/6697))

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!

- [FIP-0015](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0015.md): Revert FIP-0009(Exempt Window PoSts from BaseFee burn)
Note that this release is built on top of Lotus v1.9.0. Enterprising users can use the `master` branch of Lotus to get the latest functionality, including all changes in this release candidate.
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)

- 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).

## 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.

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.

- 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.

- 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.
