+## Unreleased
+
+### Breaking Changes
+
+* Upgrade `htmlparser2` from version 9 to version 12.
+* Require Node.js `^20.19.0 || >=22.12.0` for synchronous loading of the ESM-only backend.
+* Require TypeScript 5.3 or later for the published type declarations.
+
+### Compatibility
+
+* Preserve HTML directives and custom declarations, including PHP instructions, with the updated parser callbacks.
+* Preserve XML processing-instruction delimiters and verify native CommonJS/ESM loading and consumer types.
+* Preserve source locations immediately after XML instructions and the `lowerCaseTags` option for SVG elements.
+
+### Changed
+
+* With `decodeEntities: true`, entities in `textarea` content are now decoded, consistent with other text content. Previously `htmlparser2` left them encoded in this case.
