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.

The version everywhere moves to 2.1.248.

What

Every embedded copy of the build constants moves from version 2.1.247 to 2.1.248 with a new build time and git sha, visible in the update checker, /status, bug reports, the User-Agent header and the npm install and view commands it prints.

Evidence

BUILD_TIME: "2026-08-27T19:29:54Z", "2026-08-27T19:29:54Z"

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