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.
When a background worker crashes and is respawning, a visible message is now written to the worker's output stream: [worker crashed (<reason>) — respawning…]. Previously, crashes were silent from the user's perspective.
Evidence
New crash notification (search for "[worker crashed (")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
