BREAKING CHANGES

• CLI/RPC/Config

  • [config] #9259 Rename the fastsync section and the fast_sync key blocksync and block_sync respectively

• Apps

  • [abci/counter] #6684 Delete counter example app
  • [abci] #5783 Make length delimiter encoding consistent (uint64) between ABCI and P2P wire-level protocols
  • [abci] #9145 Removes unused Response/Request SetOption from ABCI (@samricotta)
  • [abci/params] #9287 Deduplicate ConsensusParams and BlockParams so only types proto definitions are used (@cmwaters)
    • Remove TimeIotaMs and use a hard-coded 1 millisecond value to ensure monotonically increasing block times.
    • Rename AppVersion to App so as to not stutter.
  • [types] #9287 Reduce the use of protobuf types in core logic. (@cmwaters)
    • ConsensusParams, BlockParams, ValidatorParams, EvidenceParams, VersionParams have become native types. They still utilize protobuf when being sent over the wire or written to disk.
    • Moved ValidateConsensusParams inside (now native type) ConsensusParams, and renamed it to ValidateBasic.
  • [abci] #9301 New ABCI methods PrepareProposal and ProcessProposal which give the app control over transactions proposed and allows for verification of proposed blocks.
  • [abci] #8216 Renamed EvidenceType to MisbehaviorType and Evidence to Misbehavior as a more accurate label of their contents. (@williambanfield, @sergio-mena)
  • [abci] #9122 Renamed LastCommitInfo to CommitInfo in preparation for vote extensions. (@cmwaters)
  • [abci] #8656, #8901 Added cli commands for PrepareProposal and ProcessProposal. (@jmalicevic, @hvanz)
  • [abci] #6403 Change the key and value fields from []byte to string in the EventAttribute type. (@alexanderbez)

• P2P Protocol

• Go API

  • [all] #9144 Change spelling from British English to American (@cmwaters)
    • Rename "Subscription.Cancelled()" to "Subscription.Canceled()" in libs/pubsub
  • [crypto/sr25519] #6526 Do not re-execute the Ed25519-style key derivation step when doing signing and verification. The derivation is now done once and only once. This breaks sr25519.GenPrivKeyFromSecret output compatibility. (@Yawning)

• Blockchain Protocol

FEATURES

• [abci] #9301 New ABCI methods PrepareProposal and ProcessProposal which give the app control over transactions proposed and allows for verification of proposed blocks.

IMPROVEMENTS

• [crypto] #9250 Update to use btcec v2 and the latest btcutil. (@wcsiu)

• [cli] #9171 add --hard flag to rollback command (and a boolean to the RollbackState method). This will rollback state and remove the last block. This command can be triggered multiple times. The application must also rollback state to the same height. (@tsutsu, @cmwaters)

• [proto] #9356 Migrate from gogo/protobuf to cosmos/gogoproto (@julienrbrt)

• [rpc] #9276 Added header and header_by_hash queries to the RPC client (@samricotta)

• [abci] #5706 Added AbciVersion to RequestInfo allowing applications to check ABCI version when connecting to Tendermint. (@marbar3778)

• [node] #6059 Validate and complete genesis doc before saving to state store (@silasdavis)

• [crypto/ed25519] #5632 Adopt zip215 ed25519 verification. (@marbar3778)

• [crypto/ed25519] #6526 Use curve25519-voi for ed25519 signing and verification. (@Yawning)

• [crypto/sr25519] #6526 Use curve25519-voi for sr25519 signing and verification. (@Yawning)

• [crypto] #6120 Implement batch verification interface for ed25519 and sr25519. (@marbar3778 & @Yawning)

• [types] #6120 use batch verification for verifying commits signatures. (@marbar3778 & @cmwaters & @Yawning)

  • If the key type supports the batch verification API it will try to batch verify. If the verification fails we will single verify each signature.

• [state] #9505 Added logic so when pruning, the evidence period is taken into consideration and only deletes unecessary data (@samricotta)

BUG FIXES

• [consensus] #9229 fix round number of enterPropose when handling RoundStepNewRound timeout. (@fatcat22)
• [docker] #9073 enable cross platform build using docker buildx
• [blocksync] #9518 handle the case when the sending queue is full: retry block request after a timeout
