Ouroboros-consensus-protocol Changelog

Changelog entries

0.9.0.1 — 2024-06-19

Patch

  • Updated dependencies, but no changes to the interface.

0.9.0.0 — 2024-05-13

Non-Breaking

  • Adapted to introduction of new ChainOrder type class.

  • Changed the Praos chain order such that for two blocks A and B by the same issuer with the same block number, A is now preferred over B only if A has a higher issue number and (new) A and B are in the same slot.

    This is in line with the motiviation for the issue number tiebreaker, and fixes the transitivity of the Ord PraosChainSelectView instance in a special case.

Breaking

  • Allowed to configure Praos chain order to restrict the VRF tiebreaker based on slot distance.

  • Delete Ouroboros.Consensus.Protocol.Praos.Translate, moving the orphan instance to Ouroboros.Consensus.Protocol.Praos.

  • Delete Ouroboros.Consensus.Protocol.Translate, moving TranslateProto to Ouroboros.Consensus.Protocol.Abstract.

0.8.0.0 — 2024-04-03

Breaking

  • Remove unused translateConsensusConfig from TranslateProto.

  • Add praosRandomnessStabilisationWindow to PraosParams, allowing to configure in which slot the epoch nonce is snapshotted (which can now vary between different eras).

0.7.0.0 — 2024-01-29

Patch

  • Fix imports and type mismatches caused by ouroboros-consensus bumping strict-checked-vars to ^>= 0.2.

Breaking

  • Praos' LedgerView.lvMaxHeaderSize type changed from Natural to Word16.
  • Praos' LedgerView.lvMaxBoxySize type changed from Natural to Word32.

0.6.0.0 — 2023-10-26

Breaking

  • Replace all occurrences of Ticked (LedgerView X) with LedgerView X.
  • Remove Ticked (LedgerView X) data family instances.

0.5.0.7 — 2023-09-27

Patch

  • Update upper bound on ouroboros-consensus

0.5.0.6 — 2023-08-21

Patch

  • Removed the expose-sublibs cabal flag, since Cabal/Nix handled it poorly.
  • Instead, added a unstable- prefix to the name of each sublibrary, to strongly indicate that we ignore them when evolving the package's version.

Archaeological remark

Before following a more structured release process, we tracked most significant changes affecting downstream users in the interface-CHANGELOG.md.
