A coordinated wave of releases pushed Claude Code to 2.1.241 across the entire agent SDK stack, and you need to know where it matters.

Claude Code 2.1.241 shipped overnight with "Bug fixes and reliability improvements" [1], immediately cascading through the ecosystem. The TypeScript SDK hit v0.3.241 in lockstep, with the release notes stating "Updated to parity with Claude Code v2.1.241" [2]. Your GitHub Actions are covered too: claude-code-action tagged v1.0.201 [3], and the Python SDK bumped its bundled CLI to match [4]. The patch train moved fast, with v2.1.240 [5] and v0.3.240 [6] both shipping in the same window. If you're on the previous versions, the delta is minor, but staying current avoids drift across repos. Ten commits and six releases this period, all pointing one direction: update your pins and move on.
