Thanks for providing the update! We just did a quick check applying the update with ZHA and everything still seems to work as expected. We've not noticed any visible changes from this update.

I've slightly adjusted the user-facing release notes (shown in HA) to just mention generic "Bug fixes and improvements", as most users won't know what "This release includes a full HA 1.2 feature set" means.

After applying the update, we also found that non-values for quirks v2-created entities showed as 65535 (for VOC), instead of "Unknown" briefly. This is something we may still be able to fix with zigpy/zha#758 in the next HA release tomorrow, so I'll hold off a bit on publishing the update, even if it is a minor thing. But feel free to already submit other updates.
