A Community Provider's Changelog Surfaced an Undocumented Claude Agent SDK Option: `resumeDropsTurn`
ai-sdk-provider-claude-code v4.1.0 (2026-08-10) exposes `resumeDropsTurn`, which maps a Claude Agent SDK option that drops the turn containing a given chain-entry UUID from the restored context when resuming a session — the companion to `resumeSessionAt` for forking a resumed session at a precise point. The release also bumps its exact SDK pin from 0.3.226 (from 0.3.205), noting `resumeDropsTurn` was the only new `Options` key. It is not yet in the public Agent SDK session docs, so the provider's changelog is currently the best reference.
