@cardano-ogmios/schema - npm Package Versions

[5.5.8] - 2023-01-25

Added

N/A

Changed

• Bump internal packages to match cardano-node@1.35.4 dependencies set.

• Bundle the docker image with more recent versions of the cardano-configurations.

• ![TypeScript][] Fix TxMonitorClient's nextTx wrongly throwing an error when called with no argument. The signature of that method has also been reworked slightly to provide better usage at call-site.

• ![TypeScript][] Add missing required constraints in the JSON schema for Byron witness representation that caused TypeScript types to be generated as optional.

Removed

[5.5.7] - 2022-10-27

Added

• delegationAndRewards and nonMyopicMemberRewards queries now both accept credentials in the form of bech32 strings as parameters, with the following expected prefixes and semantic (according to CIP-0005:

  • stake (resp. stake_test on test networks) for stake addresses
  • stake_vkh for stake key hash digests
  • script for stake script hash digests

  See also #277.

• ![TypeScript][] Allow additionalUtxoSet to be passed as argument in the repl.

Changed

• ![TypeScript][] Fixed additionalUtxoSet being ignored in the TxSubmissionClient of the TypeScript client.

Removed

[5.5.6] - 2022-10-21

Added

• Prometheus metrics exported at /metrics endpoint

• Schema definitions are now included in the 📘 API reference. This makes it a little easier to find a specific schema without having to drill into a messages definitions.

Changed

• Fixed network synchronization reporting 0.99999 even when fully synchronized. There was sometimes a possible discrepancy between the ledger internal clock and Ogmios' clock, causing a few seconds of drift time.

• ![TypeScript][] Fixed a couple of data-types with fields parsed as number instead of bigint. See #274

  [!WARNING] This is technically an internal breaking-change, however it actually comes as a bug fix since this does not change the announced interface in the TypeScript schema (which was correctly indicated 'bigint'). Still, this may cause issues with those using number where there will now be bigint.

• ![TypeScript][] Fixed browser detection for the IsomorphicWebSocket abstraction. See #273

Removed

[5.5.5] - 2022-08-19

Added

• ![TypeScript][] Support for the TxMonitor mini-protocol in the REPL.

• Link to a new Java client for Ogmios.

Changed

• ![TypeScript][] Fixed parsing of ScriptFailures coming out of the evaluateTx command. Before this patch, the client would simply throw undefined when such an error was encountered. They are now properly transcribed as EvaluateTxError.

Removed

• testnet has been removed from the target networks by the Docker workflow; which means that until further notice, there will be no more Docker images pushed for testnet. However, support for preprod and preview environment has been added.

[5.5.4] - 2022-08-11

Added

• Missing JSON specification (and therefore, documentation) for collectErrors. See #244.

Changed

• Slot lengths are now encoded as floating numbers (double precision) instead of integers (still representing a number of seconds). However, to maintain backward-compatibility, integers value are encoded without decimal, as they used to. #245

• ![TypeScript][] Blocks' properties (header, headerHash, body) are no longer marked as optional in the JSON specification (and consequently, in the TypeScript SDK). #238

Removed

[5.5.3] - 2022-07-31

Added

N/A

Changed

• Bumped cardano-node's version (continuous integration & docker image) to 1.35.2.

• ⚠️ Fixed Plutus' data / datum serialization function. See 3f614c3c for details. As a consequence, some datums (either inline or in the witness set) that have been reported in the past (since v5.5.0) may have been wrong. Note that the datum hashes were however correct, so it is possible to identify the "corrupted" ones by trying to re-hash (blake2b-256) them and see whether they match their associated hash digest.

• Changed the Docker image tagging's scheme of cardano-node-ogmios to now include the cardano-node's version. This allows to more easily bundle more recent version of cardano-node with old versions of Ogmios without the need to make a whole new release. This is in effect from v5.5.2 and onwards.

• Fixed incongruous error message from the command-line when failing to parse protocol parameters from genesis files. The error reporting has been slightly improved to give a more fine-grained error per invalid parameter. See #242.

Changed

• Bumped cardano-node's version (continuous integration & docker image) to 1.35.1.

• ![TypeScript][] Remove superfluous string concatenation in UnknownResultError's message. See #236.

[5.5.1] - 2022-07-05

Added

• ![TypeScript][] New isBabbageProtocolParameters helper function, and extended support of the existing ones to Babbage. See #234.

Changed

• Fixed Health endpoint wrongly reporting 'Alonzo' while in the 'Babbage era'. See #233.

[5.5.0] - 2022-06-29

Added

• Added Vasil/Babbage support, including:
  • A new block type babbage with:
    • New (optional) transaction fields references, collateralReturn, totalCollateral;
    • New (optional) transaction output's fields datum and script;
  • A new plutus:v2 script language;
• New transaction error submission failures in the Babbage era:
  • mirNegativeTransfer: return when attempting to perform a negative MIR transfer from a reward pot to another;
  • totalCollateralMismatch: returned when totalCollateral is set but does not match what is actually computed by the ledger (i.e. sum of collateral inputs minus collateral return);
  • malformedReferenceScripts: returned when the script specified in an output isn't actually a well-formed Plutus script;
  • malformedScriptWitnesses, occurs when a script witness specified in the transaction does not properly deserialize to a Plutus script.
• New script evaluation failures in the Babbage era:
  • corruptCostModelForLanguage: An artifact from a distant past. This is unused but somehow still present in the ledger internal definitions. Should be removed eventually.
• New server evaluation failures:
  • NotEnoughSynced: Happens when attempting to evaluate execution units on a node that isn't enough synchronized. This is, if the node is still in an era prior to Alonzo, evaluation of execution units won't be possible.
  • CannotCreateEvaluationContext: Happens when the ledger fails to create an evaluation context from a given transaction. This is mostly due to the transaction being malformed (e.g. wrong redeemer pointer, missing UTxO).

<p align="right">See the <a href="https://ogmios.dev/api">📘 API reference</a> for more details.</p>

Changed

• Updated cardano-configurations to include the vasil-dev network and switch to cardano-world as a source instead of Hydra artifacts -- now being deprecated.

• Partially fixed an issue causing websocket connection to be terminated by the server when p2p is enabled on the underlying node. Ogmios now has a workaround which makes the issue less likely, but the real fix belongs in the upstream networking stack. See #230, #208.

• The missingRequiredScripts error now contains an extra field resolved that is a map of (pointer → script hash) that have been correctly resolved by said pointers.

• The introduction of the Babbage era comes with some minor (albeit possibly breaking) changes and deprecations:

  • ⚠️ datums, redeemerData and plutus:v1 scripts are no longer encoded as base64 strings, but are encoded as base16 strings. The data payload remains however identical. This change is meant for more compatibility across the API since those data-types can now also be submitted to the server when evaluating execution units for transactions. Using base64 for input data here is a bit awkward since most existing interfaces in the ecosystem favor base16;

  • ⚠️ When passing transaction outputs to the server (e.g. when providing an additional UTxO for script evaluation), datum hashes in output must now be specified as datumHash (instead of datum). However, the server does a best-effort for the sake of backward compatibility and should still work if provided with a valid hash under datum. However, after the Vasil hard-fork, it'll be possible to also pass inline-datums using datum, while datum hash digest are expected to be specified as datumHash. Said differently, existing applications relying on this functionality will keep working without a change on this release, but applications willing to make use of the new inline-datum functionality coming in Vasil must abide by the new notation;

  • ⚠️ Similarly, Alonzo transaction outputs will now contain a datumHash field, carrying the datum hash digest. However, they will also contain a datum field with the exact same value for backward compatibility reason. In Babbage however, transaction outputs will carry either datum or datumHash depending on the case; and datum will only contain inline datums;

  • ⚠️ The outputTooSmall errors from transaction submission will slightly change format for transactions submitted during the Babbage era. Instead of an array of outputs, it is an array of objects with output and minimumRequiredValue fields;

  • ⚠️ A slightly modified block header: leaderValue and nounce fields are gone and replaced by a single inputVrf field;

  • ⚠️ Few protocol parameters changes:

    • A new protocol parameter coinsPerUTxOByte comes to replace coinsPerUtxoWord with a slightly different semantic. coinsPerUTxOByte is meant to compute the minimum Lovelace requirement on transaction outputs, and is simply a coefficient in a linear function of the serialized (CBOR) output:

      minUTxOValue(output) =  |serialise(output)| * coinsPerUTxOByte
      

    • The decentralizationParameter no longer exists.<br/> The block production is forever decentralized :tada:!

    • The extraEntropy no longer exists.

Removed

• UnknownInputs and UncomputableSlotArithmetic errors have been removed from the top-level possible cases of EvaluationFailure. Instead, those errors are now comprised in the CannotCreateEvaluationContext case.

• The corruptCostModelForLanguage error has been removed from the top-level possible cases of ScriptFailure. This one was effectively dead-code that couldn't be reached and was there for completeness. The code has now been removed upstream.
