Cardano Rosetta Java v2.1.0 is stay with full Conway-era governance assist, SPO Voting, DRep Delegation, and CIP-129 throughout all endpoints.
The Cardano Basis shipped one thing builders have been ready on. Cardano Rosetta Java v2.1.0 is stay, and it brings full Conway-era governance assist to each building and information endpoints. As Cardano_CF introduced on X, the replace covers SPO Voting, DRep Vote Delegation, CIP-129, and extra.
That’s not a small factor. Governance operations are actually seen contained in the API. Builders now not want workarounds.

What Modified Contained in the API
Based on the official v2.1.0 launch notes on GitHub, the replace was authored by matiwinnetou two weeks in the past. SPO Voting and DRep Vote Delegation now seem in each building and information endpoints. Operations kind by index in ascending order. That final half is small, however it was inflicting complications.
CIP-129 assist is now baked in. DRep IDs with a 29-byte prefixed header now not want an specific kind discipline. The API infers the kind robotically from the header byte. Uncooked 28-byte IDs nonetheless want kind declared manually.
The /block, /block/transaction, and /search/transactions endpoints now return VOTE_DREP_DELEGATION and POOL_GOVERNANCE_VOTE operations for Conway-era transactions.

The Breaking Change Builders Should Know
There’s one breaking change. HTTP standing codes are actually aligned with precise error classifications. All non-retriable errors return 400 Dangerous Request now. Beforehand, validation and not-found errors returned 500 Inner Server Error. Purchasers constructed round catching 500s must replace their error dealing with earlier than upgrading.
The Cardano Basis was direct about it within the launch notes. No mushy framing.
Improve Path and What Will get Reset
For customers coming from v2.0.0, this launch is absolutely suitable. No resync wanted. That’s a clear path for many present deployments.
Coming from v1.x.x is a distinct story. A full genesis resync of the yaci-indexer is required. Cardano Node information can keep; solely the indexer information must go. The discharge notes embrace a knowledge quantity elimination process.
Node model strikes from 10.5.3 to 10.5.4. Yaci additionally bumps from 0.10.5 to 0.10.6. And there may be now an experimental admin UI for the indexer sitting at http://yaci-indexer:9095/admin-ui/.
The Cardano Basis confirmed this isn’t a compulsory launch. Groups can plan the improve on their very own timelines.

What the Conway Period Really Means Right here
The Conway period is Cardano’s Voltaire section. Decentralized governance. On-chain voting. DReps. SPO participation in governance selections. It’s the a part of the roadmap that turns ADA holders into precise decision-makers on protocol modifications.
Rosetta is the API layer that exchanges and builders work together with. With out governance operations in it, these establishments had a blind spot. v2.1.0 closes that.
As @Cardano_CF put it on X, full Conway-era governance assist is now out there. That phrasing issues. Not partial. Not experimental. Full.
The contributors behind the pull requests embrace @matiwinnetou, @linconvidal, and @Sotatek-DucPhung. A number of PRs went in to get this throughout the road, together with governance information endpoint exams with golden examples and an Allure3 migration for the take a look at suite.
