Summary
The release adds shareable visual-revision URLs, a code-diff view, mention email notifications, and major List View performance work; selecting all 1,000 paragraphs fell from 16.8 seconds to 0.4 seconds in the release notes’ test. It also adds inner-block templates to registerBlockType(), React 19 import support, DataViews time and aspect-ratio fields, and public Calendar and RangeCalendar components.
Why it matters
The release improves both large-site editing performance and the primitives available to WordPress block developers.
