Changelog

This changelog contains notable changes that made into each cardano-node release, starting with version 8.0. We also provide per-Haskell-package changelogs. Please see the CHANGELOG.md for each individual package for any changes relevant for developers.

8.12.2

  • Pricing model for the size of reference scripts was changed from linear to exponential. Moreover, extra limits on the total size of reference scripts being used have been put in place.

8.12

  • Implemented CIP-0069 that improves PlutusV3 functionality by making spending datums optional and enforcing all scripts to have exactly one argument.
  • Ensure that CommitteeMinSize protocol parameter is ignored during bootstrap phase.
  • Restrict types for some protocol parameters and fixup CDDL specification to reflect actual deserializers.
  • Create pool stake distribution query for voting.
  • Included rewards accounts in stake pool distribution calculation for voting.
  • Bug fixes:
    • Fixes to DRep expiry logic and the choice of correct threshold for the committee voting

8.10

  • Retention of Anchor for proposal procedures in the ledger state in order for users to be able to query the node for those anchors

  • The minimum fee calculation has been updated to take into consideration a new protocol parameter controlling the contribution of reference scripts sizes

  • Redeemers serialization improvement: encode redeemers as a Map, instead of a list for Conway

  • Support for intra-era hardfork initiation and necessary updates to the SPO stake distribution calculation.

  • Fail translation when Conway features are present in transactions that use Plutus v1/v2

  • Remove small-steps-test package and convert it into a sublibrary of small-steps

  • Support for injecting transition configuration data in NewEpochState, to decouple this concern from Consensus

    • new committee governance action ratification was implemented incorrectly
    • guard against invalid protocol versions in hard fork initiation proposals
    • failures during updates of Plutus CostModels were not retained
    • fixed the types for some protocol parameters in order to prevent values that are too large
    • serialization and CDDL fixes for transaction witnesses in the Conway Era

    • 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

8.1

  • Plutus V3 support, only available in the conway ledger era.
  • PState is now parametric in era, not crypto.
  • Adjust for new conway era certificates.
  • Ledger UMapCompact is now UMap
  • Ledger types with names involving DState are renamed to CertState.

8.0

  • The provenance for the reward calculation has been removed. The type signature to the API function getRewardProvenance has not changed, it just returns an empty provenance value.
  • We have created a Ledger API, with the aim of providing a user-friendly interface to the ledger libraries. See here.
  • The initial funds and staking in the Shelley genesis type (used only for testing) now use ListMap instead of Map.
  • There is a new calculatePoolDistr' function which is similar to calculatePoolDistr but has a new filter argument to only include the stake pool ids (stake pool key hashes) that are needed.
  • The ledger events are not guaranteed to appear in any given order within a block. For this reason, motivated by the use case in db-sync, the TotalDeposits event now includes a transaction ID and emits the change in deposits instead of the value.
  • We changed the way deposits are tracked. See here for the details.
  • We changed the API function Cardano.Ledger.Shelley.API.Wallet(evaluateTransactionBalance) to take DPState as input. This can no longer be computed without the DPState
  • Some noticeable changes have been made which will only become apparent starting at major protocol version 9:
    • There is a new ledger era, namely conway.
    • We now have the ability to more easily change serializations when the major protocol version changes. Though this change is not immediately visible to the node, it enables visible changes in the future. See CIP-80 For the deprecation cycle.
    • Pointer addresses will no longer accrue rewards starting with version 9.
    • We fixed the incorrect conversion of the validity interval's upper bound in transVITime.
    • Starting in version 9, duplicate keys in CBOR maps and sets are no longer allowed.
    • Starting in version 9, CostModels can now be deserialized from any map of Word8 values to lists of integers. Only valid cost models are actually converted to evaluation contexts that can be used. Errors and unrecognized language versions are stored in the CostModel type so that:
      • They can accept cost models that they do not yet understand.
      • Upon deserializing after a software update, new cost models are available from the prior serialization.

Release tag ledger/1.0.0

The first release branch in the cardano-ledger repository, namely release/1.0.0, branches from the cardano-ledger commit used for the 1.35.0 release of cardano-node release.

Fixed

  • Ensure Babbage TxOut decoder can't fail due to malformed Ptr. This bug was manifesting in the cardano-node as: if a node is running in the Babbage era and shuts down, when it comes back up it has to re-sync from genesis. #2897
  • The Alonzo UTxO rule was previously using the incorrect minfee function (from Shelley). It now uses the Alonze minfee function. #2936
