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.

Multi-select edits can be vetoed by the handler

You'll notice
Useful2 Signal1
Terminal UI

Multi-select lists can reject an edit outright, and space no longer toggles on the submit button.

What

In multi-select option lists, a change handler returning false now aborts the edit outright: no text written, no cursor move, no selection. Image removal can be vetoed the same way, and pressing space while the submit button is focused no longer toggles an option.

Details
  • Submit-button focus is guarded by a new refuseSubmitFocus prop.
  • The underlying hook now also exposes a way to read the currently selected values.
Evidence

refuseSubmitFocus

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