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 v2.1.241

Version stamped to 2.1.241

Under the hood
Useful2 Signal1
Elsewhere

The version number moved from 2.1.240 to 2.1.241; nothing else changed.

What

The embedded build constants advance from 2.1.240 to 2.1.241, with a new build timestamp and commit hash. Nothing changes but the numbers.

Details
  • The version string is inlined at roughly 120 places, so it moves everything that reports a version: --version, the /status and /doctor panels, the claude-code/ and claude-cli/ User-Agent strings, the shr- prefixed environment-runner version header, the update and downgrade messages, the Remote Control minimum-version check, the daemon start log line, and telemetry group names built from the version.
  • Build time is 2026-08-22T22:46:48Z.
Evidence

GIT_SHA: "c87e2742fc9ad269ec8920460d00a091b1e410f0", BUILD_TIME: "2026-08-22T22:46:48Z"

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