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.

Sending work to a remote session can now be cancelled mid-upload

Sessions

Cancelling a handoff to a remote session now stops mid-upload instead of waiting.

What

The upload that hands your work to a remote session checks for cancellation around bundling, environment resolution and the network request itself, so cancelling no longer waits for the whole upload. The caller is also told when the request has been sent.

Details
  • A progress callback fires with request_sent at the point the log line [teleport] phase: POST-sent is written.
  • Applies to every remote handoff; not gated.
Evidence

[teleport] phase: POST-sent

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