### Enhancements
 * Show hex colours when `#` is missing. See [#1738](https://github.com/eclipse-lemminx/lemminx/pull/1738).

## [0.30.1](https://github.com/eclipse-lemminx/lemminx/milestone/47?closed=1) (April 9, 2025)

### Breaking Changes
 * Update to Java 11. See [#1721](https://github.com/eclipse-lemminx/lemminx/pull/1721).
    * _Rationale_: Several of lemminx's dependencies now require Java 11, so we were unable to update to the latest versions until we adopted it.
