Hi all, at the end of last week we released OOUI v0.52.0. It will roll out on the normal train tomorrow, Tuesday, 17 June 2025.
This release contains several breaking changes and highlights since v0.51.0: Breaking changes: - We dropped support for PHP < 8.1 - Custom OOUI\Exception class was removed entirely. Rely on the default exception handler instead. - Dialog: Remove Dialog.static.escapable - SelectFileInputWidget: Remove alias for SelectFileWidget. SelectFileWidget got superseded by SelectFileInputWidget with dropped IE11 support a while back.
Additionally - OOUI is now fully supporting dark mode with a number of fixes in different widgets, most complex fix provided to DropdownInputWidget - DropdownInputWidget also received a fix for missing accessibility labels on mobile - And PopupToolGroup won't close anymore if the scrollbar is used
Thanks to Func, Taavi Väänänen, Zoë, Umherirrender and SomeRandomDeveloper for their volunteer contributions since the last minor release.
