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.
Requests to a dead cloud session fail immediately instead of hanging

Cloud Sessions
Requests to an inactive cloud session now fail instantly instead of waiting out the full timeout.
What's wrong with this entry?
Anonymous. No account, no email.
What
When a control request cannot be posted because the session is inactive or the request fails over http, it is now rejected right away with a not-delivered error. Previously the caller waited out the full per-request timeout.
Details
The pending request is cleared and its timer cancelled as soon as the post reports failure.
Evidence

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