DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

What

The version reported by claude --version, the /status Version row, update checks and telemetry is now 2.1.231, up from 2.1.229, with a matching new build time and commit hash. Nothing else changed.

Details
  • The same version, build timestamp (2026-08-13T07:25:27Z) and commit hash are stamped into roughly 50 places across the bundle, including the claude-code/ and claude-cli/ user-agent strings, the environment runner version header, the daemon-vs-CLI mismatch warning, the Remote Control minimum-version check, /doctor and updater output, the npm lookup for the latest published version, transcript headers, OpenTelemetry attributes and cache keys.
  • No logic differs anywhere in the group; only the constants.
