NOTE: Linux is showing a git revision of 0000000000000000000000000000000000000000 in --version because of a corruption issue in set-git-rev that only affects static musl built binaries. This is expected, and if it concerns you, please build from source.

NONE

• Restructure certificate interface
• Conway related changes:
  • Introduction of a DRep with pre-defined DReps that vote No and Abstain.
  • Change DCert type to a TxCert type family and introduce new certificates
  • Implement voting on NewConstitution by StakePools as the most basic example of voting.
  • Implement query for getting Constitution hash from the ledger state.
  • Change structure of Governance Procedures in the TxBody
  • Fix TICKF rule, avoiding VRF verification and syncing issues
  • Clear out TxOuts with zero value from the UTxO upon translation into Conway

• Added --start-as-non-producing-node flag and implemented a way to enable block production dynamically: #5383, #5399. Note: we haven't yet verified if the performance regression of P2P BP nodes was fixed (ref).
• Implemented an optional explicit warm valency for local root peers: #5409.
• Implemented bootstraping for peer sharing (also known as light peer sharing): input-output-hk/ouroboros-network#3596; new trace is included: TraceKnownInboundConnection which is emitted when an inbound peer is shared with the outbound governor (and thus it could be used as an upstream peer).
• Renamed FetchDeclineChainNoIntersection as FetchDeclineChainIntersectionTooDeep: input-output-hk/ouroboros-network#4608.
• We limit concurrency used by dns resolution in P2P mode. We only resolve up to 8 dns names
  concurrently for public / ledger peers and up to 2 for local root peers.
  This will affect how quickly node connects to ledger peers when it starts. input-output-hk/ouroboros-network#4596.
• Improved memory footprint of peer metrics: input-output-hk/ouroboros-network#4620.

• cardano-cli split out to a separate repository

• Era-sensitive command structure

• Set default era to Babbage in stake-address, stake-pool and governance commands

• CARDANO_ERA environment variable support

• Make it build with ghc-9.6

• Add a query for the hash of the constitution

• Update cardano-cli with the ability to create votes and governance actions.
  Update transaction build with the ability to specify votes and governance actions.

• The --protocol-params-file option of the transaction build command is
  now marked as deprecated in Usage help. The option was already deprecated
  and ignored.

• cardano-cli ping changes:

  • timestamp format changed to ISO8601
  • added --query-versions flag, instread of doing version negotiation the remote
    side will reply with its set of supported versions.
  • fixed support for node-to-client mini-protocol over Unix socket.

• Add --conway-era flag.
