There's a couple of changes that need to made to reflect changes in Masque as of 11.2.7:

- `UdateCharge` has been renamed to `UpdateChargeCooldown`. It still works, but is deprecated.

- Masque now supports the AssistedCombatHighlightFrame and hooks SetAssistedHighlightFrameShown. The code 

if Masque and Masque.UpdateAssistedCombatHighlight then
Masque:UpdateAssistedCombatHighlight(self)
end

added to UpdatedAssistedHighlightFrame enables Masque's skinning in LBA..
