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.

Claude Code v2.1.243

Version constant bumped to 2.1.243

Under the hood
Useful2 Signal1
Elsewhere

The version number now reads 2.1.243 everywhere it shows up.

--version/status
What

The build stamp changed from 2.1.242 to 2.1.243. Everything that reports a version now reports the new one, including --version, the /status version row, the updater's npm commands, the user-agent strings and the bug-report Environment Info block.

Details
  • Only the version, build time and git commit fields changed; the package URL, README URL, issues explainer, feedback channel, hooks worker URL and sourcemap group are untouched.
  • The same build-metadata object is inlined at roughly 118 places, so the daemon start log line, the x-environment-runner-version request header and the Remote Control minimum-version message all pick it up together.
  • No behaviour change beyond the reported string.
Evidence

BUILD_TIME: "2026-08-24T21:05:22Z"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
