v0.7.0

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.

0.7.0-rc1

Release candidate for Lotus 0.7.0, a network-upgrading release to be run on the space-race testnet.

v0.6.2

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.

Miners competing in the space-race competition should upgrade to this release to ensure their PoSt messages land on-chain.

Changes

Messagepool

• Warn when optimal selection fails to pack a block and we fall back to random selection (#3708)
• Add basic command for printing gas performance of messages in the mpool (#3701)
• Adjust optimal selection to always try to fill blocks (#3685)
• Fix very minor bug in repub baseFeeLowerBound (#3663)
• Add an auto flag to mpool replace (#3676)
• Fix mpool optimal selection packing failure (#3698)

Core Lotus

• Don't use latency as initital estimate for blocksync (#3648)
• Add niceSleep 1 second when drand errors (#3664)
• Fix isChainNearSync check in block validator (#3650)
• Add peer to peer manager before fetching the tipset (#3667)
• Add StageFetchingMessages to sync status (#3668)
• Pass tipset through upgrade logic (#3673)
• Allow nodes to mark tipsets as checkpointed (#3680)
• Remove hard-coded late-fee in window PoSt (#3702)
• Gas: Fix median calc (#3686)

Storage

• Storage manager: bail out with an error if unsealed cid is undefined (#3655)
• Storage: return true from Sealer.ReadPiece() on success (#3657)

Maintenance

• Resolve lotus, test-vectors, statediff dependency cycle (#3688)
• Paych: add docs on how to use paych status (#3690)
• Initial CODEOWNERS (#3691)

v0.6.2-rc1

Merge pull request #3687 from filecoin-project/misc/v0.6.2-rc1

Bump version to 0.6.2-rc1

v0.6.1

This optional release introduces a minor improvement to the sync process, ensuring nodes don't fall behind and then resync.

Changes

• Update test-vectors (#3645)
• Revert "only subscribe to pubsub topics once we are synced" (#3643)

v0.6.0

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.
