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

This is version 2.1.242, built from commit 2482ce9083708842d832441fde1721626f306157. The CLI gained a first-argument mode --eval-mock-server taking two positional arguments, which prints the error and exits 1 on failure, and the build constants gained a URL for the bundled hooks worker script.

Evidence

--eval-mock-server:

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