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.

Rewind now refuses more precisely when the client is behind

You'll notice
Useful2 Signal2
Sessions

A refused rewind now says "unseen later turn" instead of a vague stale-target message.

What

A rewind request can now include the id of the last user message the client actually saw. If turns exist after the rewind point that the client has not seen, the refusal says "unseen later turn" rather than the old catch-all "stale target".

Details
  • A prompt that is queued but has not started is now refused separately as "prompt pending".
  • The queue check counts the drainable main-thread queue rather than testing a boolean for pending user intent.
  • Unconditional in this build.

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