v7.0.0

Added

• Preliminary support for the Dijkstra era and PlutusV4. The Dijkstra era is not officially available, so expect (breaking) changes in the schema moving forward; though a best effort will be done to avoid any important breaking changes.

• Missing plutusCostModels and minFeeReferenceScripts properties from Conway's genesis object.

Changed

• Dependencies and compatibility to cardano-node==11.0.1.

• Ogmios not returning a success error code when interrupted by the user (e.g. CTRL+C / SIGINT).

• When evaluating transactions, additional utxos provided manually are now preferred over those automatically resolved (allowing to override more easily existing utxos for testing).

• The treasury field on transaction was sometimes ommitted when it should've been present; this is now fixed.

• ⚠️ BREAKING-CHANGE ⚠️: on ProtocolParameters and ProposedProtocolParameters, the field maxReferenceScriptsSize has been renamed to maxReferenceScriptsSizePerTransaction to disambiguate it from maxReferenceScriptsSizePerBlock.

• ⚠️ BREAKING-CHANGE ⚠️: transaction object now omits the validityInterval and outputs fields when they're empty.

• ⚠️ BREAKING-CHANGE ⚠️: Byron bootstrap witness encoding has changed from a single 64-bytes key payload to a combo key + chain-code.

Removed

• ⚠️ BREAKING-CHANGE ⚠️: transaction submission and evaluation no longer include shelley, allegra and mary parsing hints on errors. Only alonzo onwards is included.

v6.14.0

Added

• queryLedgerState/delegateRepresentatives now returns the list of delegators also for the pre-defined always-abstain and always-no-confidence dreps.

Note

Couldn't get the query available in the cardano-node on-time, so this is still not available in this release, but should be ready for the next as soon as a version of cardano-node with support for the GetDRepsDelegations ledger state query is released.

Changed

• Bump dependencies to cardano-node==10.5.1.

• queryLedgerState/stakePools will also include the stake of pools that have just retired. This is useful to consider the voting power granted to such pool for the upcoming epoch ratification.

• Ogmios will now attempt to negotiate older versions of the client protocols, so that it can work with tools and libraries that are lagging behind. Ogmios will go as low as node-to-client version 17. Beyond that, some queries will no longer work and the overall user experience would be degraded.

Removed

• queryLedgerState/proposedProtocolParameters is no longer available in the underlying node and was already returning dummy data for a few versions. It's been removed.

v6.13.0...v6.14.0

v6.13.0

Added

• A new query queryLedgerState/rewardsProvenance which now re-implements and exposes the intermediate rewards calculation. The query name already exists, but the schema is now different. The previous behaviour can be recovered by using the new queryLedgerState/stakePoolsPerformances instead. (🔨 @KtorZ)

Changed

• ⚠️ BREAKING-CHANGE ⚠️: queryLedgerState/dump no longer return a hex-encoded CBOR dump as part of the JSON response, but instead, serialise directly to a specified on-disk location. (🔨 @jeluard, @KtorZ)

• ⚠️ BREAKING-CHANGE ⚠️: queryLedgerState/rewardsProvenance has been renamed to queryLedgerState/stakePoolsPerformances. The schema remains otherwise unchanged. (🔨 @KtorZ)

• ⚠️ BREAKING-CHANGE ⚠️: queryLedgerState/rewardAccountSummaries now returns a list of results instead of a map. While this is technically a breaking change, it is necessary to fix scenarios where a credential exist as both script and verification key and would therefore lead to conflict in the key space. The response is otherwise similar to its previous form. (🔨 @KtorZ)

Additional contributors through reports and suggestions: @xray-robot, @mpizenberg. Thank you ❤️.

v6.12.0

Added

• Two new ledger-state queries:
  • queryLedgerState/nonces: internal node's rolling nonces calculations used in consensus.
  • queryLedgerState/operationalCertificates: internal stake pool operational certificates states used in consensus.

Changed

• The queryLedgerState/rewardAccountSummaries now includes the delegate representative -- a.k.a DRep -- (if any) for each summary under a field delegateRepresentative. The field delegate has also been renamed to stakePool to disambiguate both. Also, the stakePool field is now optional and may be omitted in case where a particular account is only delegated to a DRep. Similarly, the field delegateRepresentative will be ommitted when the account is only delegated to a stake pool.

• The queryLedgerState/delegateRepresentatives no longer discards registered DReps that have unregistered but whose stake is still available. This may happen when a DRep is already unregistered, but his stake distribution is still available because still needed to ratify votes on the next epoch boundary. As a consequence, some of the fields for the registered drep summaries are now optional instead of required."

v6.11.0

Added

• The queryLedgerState/stakePools query now take an optional includeStake: bool parameter. When provided and set to true, each stake pool result will include an additional stake field with its current absolute live stake (reflecting its governance power).

• A new query [queryLedgerState/delegateRepresentatives] to fetch all registered (and pre-defined) DReps, alongside their metadata and live stake. In a similar fashion to many other queries, DReps can be filtered using keys or scripts credentials in the query parameters. When both are omitted, all representatives are returned.

• New ledger-state query ledgerState/dump which dumps the ENTIRE ledger-state as base16-encoded CBOR. That query is mostly for advanced used only, and spits out a lot of data. Use only if you know what you're doing.

v6.8.0...v6.9.0

v6.8.0

Added

• Integrate cardano-node==9.2.0 and associated dependencies.

• Add new ledger-state query: queryLedgerState/governanceProposals to retrieve currently active governance proposals and their ratification state (i.e. ongoig votes).

Caution

This new ledger-state query requires cardano-node >= 9.2.0

Changed

• Fix automatic transaction upgrade to NOT change underlying binary format during upgrade. The previous implementation would on some occasions alter the serialized form, thus causing transaction hash to change and invalidating all signatures on it. The new approach does always preserve binary serialisation, but as a result, makes more scenario not translatable (e.g. trying to translate a multi-asset UTxOs containing a 0 quantity is impossible when targetting Conway).

• Fix JSON deserialization of metadata on web platforms. 🔨 @Sluder
