- LE_PARTY_CATEGORY_INSTANCE will query information about your "fake" group -- the group created by the instance/battleground matching mechanism.

MiniMapLFGFrameandMiniMapBattlefieldFrameis renamed/merged toQueueStatusMinimapButton. ShapeshiftBarFrameis removed; druid shapeshifting UI is now handled by theStanceBarFrame.
Observed bugs and notable differences
- UnitIsGroupAssistant - the new version of UnitIsRaidOfficer returns false if the player is leader. The old function returned true.
- UnitInRange - when not in a party/raid, the new version of UnitInRange returns false for "player" and "pet". The old function returned true.
- Texture:SetTexture - If the path passed into Texture:SetTexture(path) is invalid, the texture will display as solid green.
- Texture:GetTexture - If the path passed into Texture:SetTexture(path) is invalid, Texture:GetTexture() will still return whatever was passed in. Previously, it would return nil if the texture path was invalid. It seems that it is no longer possible to determine if a texture is valid or not (useful for validating user input).
- UnitGUID - requesting the GUID of another party member (possibly raid too - not tested) while responding to the new GROUP_ROSTER_UPDATE event during initial UI load while you are already in a group returns nil. This was not previously the case with the old PARTY_MEMBERS_CHANGED and RAID_ROSTER_UPDATE events.
- COMBAT_LOG_EVENT / ENVIRONMENTAL_DAMAGE - the environmental type reported from this event is now reporting non-localized proper case strings (e.g. "Falling") instead of non-localized capitalized strings (e.g. "FALLING").
