I've not seen it mentioned in any of the official 3.0 changes lists - but has anyone seen any mention of them fixing GetWeaponEnchant() so that it tells you WHICH enchant a weapon has - instead of making you scrape the weapon tooltip???
Also - it doesn't seem to return values for DK RuneForging 'enchants' which suggests there's possibly separate (AGAIN!) API functions for those - again I've not seen any mention of this tho??
Sniffing the itemlink and getting the enchant ID, then checking it against a static list is your best bet, unless there is API that I'm unfamiliar with, that returns the localized enchant name.
