Source Intelligence

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.

Most of this release is the version stamp and compiler churn

Under the hood
Useful1 Signal1
Elsewhere

Nearly all of this release is repeated build-constant updates and renamed variables, not real changes.

What

About 90 of the changes are the same build-constant block re-emitted at each place it is used. The rest, including the GitLab merge-request URL pattern, git worktree paths, test and typecheck command detection, the login-error check and a long tail of reformatting in the MCP and plugin sync code, are identical apart from renamed internal variables.

Evidence

GIT_SHA: "d235569e3f61fc4d9aacd7c85e6d1b6253e03f52"

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