The last release, OOUI v0.24.3, caused some annoying issues. The next release was planned to be OOUI v0.25.0 and it has a few breaking changes already merged. We should release OOUI v0.24.4 before it, with some backported patches, so that we can have the fixes for v0.24.3 deployed separately from the inevitable new breakage from v0.25.0.
Patches to backport:
* (T182359) https://gerrit.wikimedia.org/r/398207 ClippableElement: Fix JS error when Floatable is mixed in but disabled
** (already backported to MW in https://gerrit.wikimedia.org/r/#/q/I764a96780e418830e5c92ec57c50f549951ff47f, we must include this to avoid regressing)
* (T183069) https://gerrit.wikimedia.org/r/398195 Introduce OO.ui.getDefaultOverlay
* (T183069) https://gerrit.wikimedia.org/r/398196 Put menus/popups of infused PHP widgets into the default overlay
* …
@Volker_E and @matmarex are both available to do this on Wednesday.
