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.

Theme and terminal capability state moved onto objects

Under the hood
Useful2 Signal1
Elsewhere

Themes and terminal probe results moved onto objects, and huge theme files are skipped.

What

Custom theme bases, user and plugin themes and the detected system theme now sit on one object with a change notifier, and terminal probe results (version query, synchronized output, background colour query, native cursor) sit on another that can be reset. User themes can also be listed and read in bulk through the storage backend, with paging capped and individual theme files over 256KB skipped. If that listing fails or hits its cap, already-loaded themes are kept instead of being cleared.

Evidence

exceeds 256KB; skipping

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