May 2025 — PostgREST/postgrest delivered security, reliability, and developer-experience improvements across JWT authentication, schema cache handling, RPC behavior, and configuration parsing. JWT enhancements include test coverage for aud, corrected error mappings for unknown roles, refined error presentation, and supporting docs/testing utilities. Schema cache integrity fixes address duplicates caused by OID collisions by introducing a classoid condition in pg_description joins, with updated tests. RPC: max-affected behavior for DELETE/PATCH introduced and documented, with boundary-case tests. Config: parsing and error handling improvements allow empty db-extra-search-path and enhanced logging of config values during schema cache load errors, plus cleanup of Config.hs. These efforts reduce misconfigurations, improve security and reliability, and raise developer productivity through clearer docs and tests.
