 # Lotus changelog

+# 1.16.0 / 2022-06-24
+
+
+This is a MANDATORY release of Lotus that introduces [Filecoin network v16,
+codenamed the Skyr upgrade](https://github.com/filecoin-project/community/discussions/74?sort=new#discussioncomment-2392151).
+
+The network is scheduled to upgrade to nv16 at epoch 1960320, on July 6th at 2022-07-06T14:00:00Z. All node operators, including storage providers, must upgrade to this release (or a later release) before that time. Storage providers must update their daemons, miners, market and worker(s).
+
+Your lotus node will switch from the Legacy VM (that depended on go-based specs-actors) to Filecoin Virtual Machine FVM (that uses Rust-based builtin-actors) atomically upon the upgrade.
+
+The Skyr upgrade introduces the following FIPs, enhancements and bug fixes, delivered in [built-actors v8](https://github.com/filecoin-project/builtin-actors/releases/tag/v8.0.0) and [ref-fvm v1.0.0](https://github.com/filecoin-project/ref-fvm/releases/tag/fvm%40v1.0.0):,
+
+- [FIP-0030](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0030.md)
+- [FIP-0031](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md)
+- [FIP-0032](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0032.md))
+- [FIP-0027](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0027.md)
+- [Bug fix for the ProveReplicaUpdates method](https://github.com/filecoin-project/builtin-actors/pull/138)
+- [New proofs version for SnarkPack](https://github.com/filecoin-project/builtin-actors/pull/474/commits/3027c365f516e1cba6f156d4fb9dbd8c893d5b62)
+
+
+## 🆕 Things you may wanna know
+
+### Actor Code CIDs
+
+As stated in [FIP-0031](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md)- [structure of the code cid](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0031.md#structure-of-code-cids), system actors' code CIDs will be real content-addressing
+
+For lotus users, we are making the change minimal for you. This means the `CODE` output when you run `lotus state get-actor` will now be the actual CID that represents the executable code for the actor, followed by wrapped synthetic id like the ones you've got before, i.e `fil/8/system`.
+
+Moreover, this also means that in the future, whenever the actor code changes, the CID changes accordingly, and a network upgrade is needed for the network participants to have consensus over what executable code we should use for each system actor.
+
+### Built-in actor bundles
+
+As the network introduces FVM, it's also switching from spec-actor (written in GoLang) to [built-in actor](https://github.com/filecoin-project/builtin-actors) (written in rust), in which the latter comes with[ importable bundles](https://github.com/filecoin-project/builtin-actors#importable-bundle). This means, like filecoin proof parameters, node operators now also need to fetch the actor bundles according to the network versions for the nodes to remain operational.
+
+Bundles for all networks(mainnet, calibnet, and etc) are included in the lotus source tree (`build/actors/`) and embedded on build. Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in `build/builtin_actors_gen.go`, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running `lotus state actor-cids --network-version 16`.
+
+The manifest CID & full list of actor code CIDs for nv16 using v8.0.0 is:
+
+```
+    "_manifest":         "bafy2bzacebogjbpiemi7npzxchgcjjki3tfxon4ims55obfyfleqntteljsea"

+	"verifiedregistry": "bafk2bzaceb3zbkjz3auizmoln2unmxep7dyfcmsre64vnqfhdyh7rkqfoxlw4"
+```
+
+All bundles are also available at https://github.com/filecoin-project/builtin-actors/releases, thus you can also manually download the bundles and place them in the right path.
+
+Note: use customized bundle will risk you to lose sync with the network!
+
+To get Code CIDs:
+- api:`StateActorCodeCIDs`
+- cli: `lotus state actor-cids`
+- cli: `lotus-shed cid inspect-bundle`
+
+### Execution Trace
+
+For developers that are dependent on lotus execution trace, you will need  to enable `LOTUS_VM_ENABLE_TRACING` envvar to get the exact execution trace response as before. Without the envvar enabled, `Subcall` details, Duration` and `GasCharges` fields will be missing from the new FVM trace.
+
+### Deal Proposal Migration
+
+All deal proposals with non-utf8 string as the label in the metadata store will perform a light migration to new format as defined in [v1.1.1](https://github.com/filecoin-project/go-fil-markets/pull/721).
+
+## Others
+- Resource manager is now only enabled by default on full daemon node. You can enable it manually for other nodes by setting env var `LOTUS_RCMGR` to `1`.
+- Fix: drand: calculation of round from Filecoin epochs ([filecoin-project/lotus#8606](https://github.com/filecoin-project/lotus/pull/8606))

+# 1.15.2 / 2022-05-06
+
+This is a highly recommended feature lotus release v1.15.2. This feature release introduces many new features and  for SPs, including PoSt workers, sealing scheduler, snap deal queue and so on.
+
+Note: You need to be using go v1.17.9&up from this release onwards.
+
+## Highlights
+### ❣️❣️❣️ PoSt Workers ❣️❣️❣️
+‼️️Attention - the long-awaited yet highly requested PoSt workers, they are here! And they come in as a combo: you may setup PoSt workers for both winningPoSt or/and windowPoSt worker. You can also setup any number of PoSt workers as long as you have the hardware resources!
+For more details and learn how to set it up, see the docs [here](https://lotus.filecoin.io/storage-providers/seal-workers/post-workers/). You can also find early result of the PoSt workers performance by the community [here](https://github.com/filecoin-project/lotus/discussions/8375).
+- feat: PoSt workers ([filecoin-project/lotus#7971](https://github.com/filecoin-project/lotus/pull/7971))
+- feat: storage: Parallel proving checks ([filecoin-project/lotus#8391](https://github.com/filecoin-project/lotus/pull/8391))
+  - adjust `ParallelCheckLimit` according to your resource setup to get pre-post checkers run faster!
+
+In addition, we also added some handy toolings:
+- feat: miner: API/CLI to compute window-post ([filecoin-project/lotus#8389](https://github.com/filecoin-project/lotus/pull/8389))
+  - run `lotus-miner proving compute window-post` to manually trigger a full windowPoSt computation for a specific deadline for full sanity checks.
+- feat: miner cli: Separate proving workers command ([filecoin-project/lotus#8379](https://github.com/filecoin-project/lotus/pull/8379))
+  - run `lotus-miner proving workers` to list all the PoSt workers that's attached
+- feat: miner cli: proving check --faulty, faults in storage list sectors ([filecoin-project/lotus#8349](https://github.com/filecoin-project/lotus/pull/8349))
+  - run `lotus-miner proving check --faulty` to identify the sectors that might be bad.
+
+### 🔥🔥🔥 Sealing Scheduler Enhancement 🔥🔥🔥
+
+Have you ever got a couple workers but only a few of them are super packed, while the rest are idling waiting for jobs? Now the task can be distributed more evenly with:
+- feat: sched: Improve worker assigning logic ([filecoin-project/lotus#8447](https://github.com/filecoin-project/lotus/pull/8447))
+
+### 🌟🌟🌟 Snap Deal Enhancements 🌟🌟🌟
+
+The Filecoin Network introduced Snap Deal with the network v15 OhSnap upgrade, and lotus shipped v1.14.0 with basic snappy support for SP to use this feature. Since then, we have received good ux feedbacks and bug reports from the community, and we are introducing a couple enhancement for SPs to better leverage this feature.
+
+- feat: sealing: Sector upgrade queue ([filecoin-project/lotus#8330](https://github.com/filecoin-project/lotus/pull/8330))

+# 1.15.1 / 2022-04-07
+
+This is a *HIGHLY recommended* feature release v1.15.1, especially for node operators and storage providers who want to be a part of the content addressing network of Filecoin and IPFS.
+This feature release introduces Index Provider, GraphSync v2, and many other latest functionalities, improvements and bug fixes. More importantly, node operator can now enable the FVM(experimental) to sync mainnet!!
+
+## Highlights
+
+### 🔥🔥🔥 FVM (Experimental) 🔥🔥🔥
+- feat: fvm: FVM integration  ([filecoin-project/lotus#8332](https://github.com/filecoin-project/lotus/pull/8332))
+  The lotus team is excited to announce the launch of experimental non-programmable FVM on mainnet. By enabling `"LOTUS_USE_FVM_EXPERIMENTAL=1` envvar, the lotus daemon will be running the [WASM-compiled built-in actors](https://github.com/filecoin-project/builtin-actors) that is compatible with the existing chain(Network v15 OhSnap). If you are trying it out and having any questions or feedbacks, please leave a comment [here](https://github.com/filecoin-project/lotus/discussions/8334)!
+  - chore: FVM: log when fvm is used([filecoin-project/lotus#8363](https://github.com/filecoin-project/lotus/pull/8363))
+  - chore: ffi: the latest fvm release([filecoin-project/lotus#8382](https://github.com/filecoin-project/lotus/pull/8382))
+
+### 🌟🌟🌟 Index Provider (Production Ready!) 🌟🌟🌟
+- feat: markets: Integrate index ingest protocol and retrieve by any CID ([filecoin-project/lotus#7313](https://github.com/filecoin-project/lotus/pull/7313))
+
+More and more useful data is being stored on Filecoin via deals made by clients to Storage Providers. The goal is that this content is discoverable when people need them. To achieve that goal, one of the projects [the Bedrock team](https://www.notion.so/pl-strflt/Bedrock-2e956d5d8143432080a1d84435ccf0ff) is working on is building an Indexer Ecosystem, a project that's focus on content addressing on Filecoin, then potentially have interoperability with IPFS in the future and eventually serve the retrieval market. The Indexer Ecosystem high level architecture overview diagram can be found [here](https://github.com/filecoin-project/storetheindex/blob/main/doc/indexer_ecosys.png) and a detailed write up about can be found [here](https://www.notion.so/pl-strflt/Introducing-Indexer-to-SP-90bf296794174a8281c121d4ce6747a0).
+
+That being said, with this release, lotus Storage Providers can easily become an Index Provider and serve the Indexer Content Addressing System. Index Providers generate advertisements from the deals made by a storage provider and announces the data to the indexer nodes for further processing:
+- To learn more about *what is an Index Provider and how to be an Index Provider*, read it [here](https://lotus.filecoin.io/storage-providers/operate/index-provider/) in lotus docuementation.
+- An [one-off migration](https://lotus.filecoin.io/storage-providers/operate/index-provider/#first-time-migration) is needed in order for a Storage Provider to become an Index Provider and announce the proper formatted index. It's *highly recommended* for all Index Provider to do a [force bulk initialization](https://lotus.filecoin.io/storage-providers/configure/dagstore/#forcing-bulk-initialization) to enable index announcement on all existing deals.
+  - Note that the Initialization places IO workload on your storage system. SP should set a proper `concurrency` based on your hardware or can stop/start initialization at their wish/convenience as proving deadlines approach and elapse, to avoid IOPS starvation or competition with window PoSt.
+- After the first one-time migration, being an Index Provider barely puts any extra usage on SP's market system.
+  - You can find the testing result by SPX fellows [here](https://github.com/filecoin-project/lotus/discussions/8087).
+
+We recommend all Storage Providers that are serving deals in the Filecoin network to become a Index Provider, make the data you are storing discoverable for the retrieval market and retrieval clients!
+- If you have any questions about becoming an index provider, or the indexer system in general, leave a comment [here](https://github.com/filecoin-project/lotus/discussions/8341).
+- Follow the indexer project at https://github.com/filecoin-project/go-indexer-core.
+- If you have any feature request or bug reports of running an index provider, create an issue in https://github.com/filecoin-project/index-provider.
+- You may also join the #storetheindex channel in the Filecoin Slack to engage with the team & the community!
+
+### ❗️❗️❗️ Dag Migration For New CAR index format in DagStore ❗️❗️❗️
+The index provider leverages the latest CARv2 indexing format `MultihashIndexSorted`, which stores the multihash code as well as the digest of all CIDs in a CAR file. Thus, all Storage Providers SHOULD perform an one-off DAG mirgation to regenerate DagStore CARv2 indices. You have to do it to become an index provider, failing to do so may also impact your future deal making.
+Follow the instruction [here](https://lotus.filecoin.io/storage-providers/operate/index-provider/) to perform the migration.

+# Bundles
+
+This directory includes the actors bundles for each release. Each actor bundle is a zstd compressed
+tarfile containing one bundle per network type. These tarfiles are subsequently embedded in the
+lotus binary.
+
+## Updating
+
+To update, run the `./pack.sh` script. For example, the following will pack the [builtin actors release](https://github.com/filecoin-project/builtin-actors/releases) `dev/20220602` into the `v8` tarfile.
+
+```bash
+./pack.sh v8 dev/20220602
+```
+
+This will:
+
+1. Download the actors bundles and pack them into the appropriate tarfile (`$VERSION.tar.zst`).
+2. Run `make bundle-gen` in the top-level directory to regenerate the bundle metadata file for _all_ network versions (all `*.tar.zst` files in this directory).
+
+## Overriding
+
+To build a bundle, but specify a different release/tag for a specific network, append `$network=$alternative_release` on the command line. For example:
+
+```bash
+./pack.sh v8 dev/20220602 mainnet=v8.0.0 calibrationnet=v8.0.0-rc.1
