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.

Version bump to 2.1.226

The version number ticks up to 2.1.226; nothing else changes.

What

The build-constant stamp is rewritten: VERSION moves from 2.1.225 to 2.1.226, BUILD_TIME from 2026-08-07T19:37:58Z to 2026-08-08T00:42:40Z, and GIT_SHA to e140b3281c1e8d834468889bd0a5c3fd2f15507c. Nothing changes beyond the reported version.

Details
  • The constant is inlined at every use site, so all 52 changes in this group are the same object re-stamped.
  • Visible in the startup banner, --version output, the Current version: line in the update flow, and the update/downgrade console messages.
  • Sent in the claude-code/ and claude-cli/ User-Agent strings and in the x-environment-runner-version header, where it is prefixed shr-.
  • Also drives the daemon-vs-CLI mismatch warning, the /doctor and feedback reports, the SDK get_binary_version control response, the npm update check's npm view <package>@<tag> version call, the Datadog sourcemap group identifiers, and the version field on numerous telemetry events.
  • Not gated; everyone on this build sees it.
Evidence

x-environment-runner-version, VERSION: "2.1.226"
