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 v2.1.245

Version bumped to 2.1.245

Under the hood
Useful2 Signal1
Elsewhere

The version number moves to 2.1.245; nothing else about this area changed.

What

The build stamp moves from 2.1.243 to 2.1.245. Nothing else in this area changed.

Details
  • Build time is now 2026-08-25T04:00:18Z, up from 2026-08-24T21:05:22Z.
  • The version string is copied into every place that reports it: the CLI version output, the claude-code/ and claude-cli/ user-agent strings, update and downgrade messages, daemon start logs, and the SDK binary-version response.
  • Around 110 of the 118 changes in this group are the same constant repeated across bundled modules, so this release carries almost no other code change here.
Evidence

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