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 embedded build constants move to version 2.1.227 with a new build time and commit hash. These show up in -v, --version, the claude-code/ and claude-cli/ user agents, the x-environment-runner-version header, npm install and view targets, doctor output, bug report metadata, daemon start and version-mismatch messages, auto-updater hints, remote-control minimum-version errors, and the SDK binary version reply.

Evidence

VERSION: "2.1.227", BUILD_TIME: "2026-08-10T18:40:15Z"
