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 v2.1.251

Worktree consistency check accepts merge commits

You'll notice
Useful3 Signal3
Worktrees

Worktrees with merge commits no longer fail the history consistency check.

What

The check that verifies a worktree's commit history looks as expected now accepts a commit with any number of parents, provided each one is in the known set, instead of insisting on a fixed three-parent shape. Histories containing merges no longer fail the check.

Evidence

i.length > jgt

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