What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **changed** — Colors now preserve analogous sets of missing channels during conversions, per the CSS spec, so color.to-space(lch(50% none none), lab) now returns lab(50% none none) instead of lab(50% 0 0)

#### Changes

* **Potentially breaking compatibility fix:** Colors now preserve "analogous sets" of missing channels during conversions, per the CSS spec. For example, `color.to-space(lch(50% none none), lab)` now returns `lab(50% none none)` instead of `lab(50% 0 0)`.
