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.

The fullscreen renderer prompt no longer switches out from under active work

You'll notice
Useful3 Signal3
Terminal UI

Accepting the fullscreen renderer now queues the restart and backs out if new work arrives.

What

Accepting the "Try the new fullscreen renderer?" prompt now queues the switch instead of restarting immediately, shows a "Restarting into the fullscreen renderer…" notice, and backs out if the session picked up new work in the meantime, telling you it is keeping the current renderer.

Details
  • The queued action yields to open panels rather than interrupting them.
  • Applies to everyone shown the upsell dialog.
Evidence

Keeping the current renderer — the session picked up work a restart would drop.

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