Cardano Rosetta Java v2.1.0 Brings Full Governance Support

The Cardano Foundation has released an updated version of the Rosetta Java API, which is used by developers working with the Cardano blockchain. This latest update, v2.1.0, includes full support for Conway-era governance operations, which allows for decentralized decision-making and on-chain voting.

With this release, SPO Voting, DRep Delegation, and CIP-129 are now available in both construction and data endpoints. This means that developers no longer need to work around these features, making it easier to build applications that utilize governance operations.

The update also includes a breaking change in error handling. Previously, validation and not-found errors returned a 500 Internal Server Error status code, but now they will return a 400 Bad Request status code. This requires clients built with the previous version of the API to be updated accordingly.
