• RpcClient keeps the entries of requests that fail without a reply

• Docs that contradict the code: MCP.md's adapter list, RcMap capacity eviction, disableChecks, an unbounded "max attempts" retry example, the @effect/vitest logging example, and names v4 does not have

• @effect/vitest: it.prop passes a property that returns an Effect, without running it

  Effect-TS/effect#9373 · Filter by author nick-inkeep opened on Oct 16, 2026

• RcMap, RcRef and ScopedCache: a dying release is lost on idle expiry, an interrupted lookup, or expiry during keys/values/entries

• PersistedCache: a stored entry that no longer decodes fails every get until it expires, instead of being recomputed

• HydrationBoundary: an atom the registry already holds keeps its old value after commit, until one of its readers re-renders

  Effect-TS/effect#9343 · Filter by author nick-inkeep opened on Oct 16, 2026

• Schema: a filter's message annotation drops the path the filter reported, moving the issue to path: []
