Jul 1, 2025July 2025: Delivered a major Epoch API expansion, data-model simplification, reliability improvements, and governance updates for MystenLabs/sui. Key features include GraphQL Epoch API enhancements with extensive new fields and a flattened, lazy-loaded Epoch data model, plus fixes to epoch end bounds and updated tests. Reliability improved via indexer error handling (From<bcs::Error> for RpcError). Governance ownership clarified with CODEOWNERS update to the devx-indexers-and-rpcs team. These changes enable richer epoch analytics, faster queries, more robust indexing, and clearer team responsibility.
