v29.0.0

Compare Source

Breaking changes:

• Node.js v22.13.0+ is now the minimum supported v22 version (was v22.12.0+).

Other changes:

• Overhauled the CSSOM implementation, replacing the @acemir/cssom and cssstyle dependencies with fresh internal implementations built on webidl2js wrappers and the css-tree parser. Serialization, parsing, and API behavior is improved in various ways, especially around edge cases.
• Added CSSCounterStyleRule and CSSNamespaceRule to jsdom Windows.
• Added cssMediaRule.matches and cssSupportsRule.matches getters.
• Added proper media query parsing in MediaList, using css-tree instead of naive comma-splitting. Invalid queries become "not all" per spec.
• Added cssKeyframeRule.keyText getter/setter validation.
• Added cssStyleRule.selectorText setter validation: invalid selectors are now rejected.
• Added styleSheet.ownerNode,...
