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.
Terminal mouse wheel events now properly dispatch as wheel DOM events with deltaY, deltaX, and modifier key tracking (ctrl, shift, meta), enabling scroll-based interactions in the UI.
Evidence
Wheel event class (search for "wheelup" and "wheeldown")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
