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.

Cleaning up stale locks no longer removes the caller's own

Stale lock cleanup no longer deletes the lock the running process holds.

What

The helper that sweeps away leftover lock files can now be told to spare one path, so a process cleaning up stale siblings does not delete the lock it is currently holding.

Evidence

.filter((o) => o !== t)

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