Gatherer 7.3.1 (r1186), which supports WoW 7.3 (Legion), has now been released.
New in this release:
* Updates for WoW 7.3
* Fixes issue with sounds
* Many 7.3 related localization updates
There are some known issues with this release:
* The cursor will sometimes show a green square rather than a proper gathering icon. This is a Blizzard bug, which they will need to correct.
* It includes some localizations, but many are not available yet (until we can get updates from Wowhead).
Also, GatherDB has not yet been updated. It too is awaiting data from Wowhead.
