Every patch has its patch notes listing changes. However, for reasons that are not entirely clear to me, every patch also comes with a bunch of undocumented changes, not listed in the patch notes. Thanks to WoW's tireless army of enthusiasts, many of these changes come to light, and are collected in places like this World of Raids post. There's nothing that looks terribly important to my eye; however, for the sake of completeness, it's all copied after the jump. The changes that look the least unimportant:
- New items have been added to SSC bosses loot tables (some of them can be viewed here)
- the Monstrous Kaliri [changed] to not attack people on the ground (Skettis)
- Fire Elemental Totem now cause guards to aggro them when dropped in neutral cities.
