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.
Escape and navigation keys no longer wipe a selection

Terminal UI
Escape and page/arrow navigation no longer wipe your text selection or get swallowed by the scroll view.

What
Escape used to clear the current text selection and be swallowed by the scroll view. It now falls through to whatever else handles Escape, and the same exemption covers page up, page down, Ctrl+Home, Ctrl+End and shifted or modified arrow keys.
Details
Ordinary typing still clears the selection, as does the selection:clear binding.
Evidence
selection:clear
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
