OOjs UI 0.8.0 has been released today. It will be in MW from 1.25wmf19+.
*Breaking changes since last release:*
- [BREAKING CHANGE] Make default distribution provide SVG with PNG fallback (Bartosz Dziewoński)
We've tagged this as a breaking change, but the only breakage is renaming the stylesheet files. This will only "break" for systems which are responsible for importing the library. This is fixed for MediaWiki and for VisualEditor standalone; no other users should be affected.
As part of this change, from MediaWiki 1.25wmf19 onwards, OOjs UI will provide raster icon fallbacks for the vector icons, which we were previously not using.
*Deprecations since last major release:*
- DEPRECATION: TextInputWidget: Deprecate 'icon' and 'indicator' events (Bartosz Dziewoński)
The functionality they expose (user clicking on the icon/indicator) is fundamentally not accessible: the icon/indicator is not focusable (has no tabindex), has no keyboard events, doesn't have a label associated or a tooltip, and has no sensible way of fixing all of this. If something needs to be clickable separately, it should probably be a separate Widget with the appropriate mixins added.
- DEPRECATION: ButtonWidget: Rename nofollow config option to noFollow (C. Scott Ananian)
We're switching this feature (added just last release) to use consistent camel case. The old `nofollow` property still works for backward compatibility, but it is deprecated and will be removed in the next major release but one.
If you have any further questions or need help dealing with deprecations, please let me know.
