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.

Cloud event uploader can keep undelivered events on close

Under the hood
Useful2 Signal2
Cloud Sessions

The cloud event uploader can keep pending events on close and splits oversized batches.

What

The batching uploader can now retain in-flight and pending events when closed, exposes peek/take/discard accessors, and splits an enqueued array larger than the queue cap into successive batches instead of deadlocking.

Evidence

retainUndelivered

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