Blizzard has now posted the patch notes for the 1.10 patch on the official WoW community site (the patch itself is not yet on the testing servers). Changes include ambient zone weather, new armor sets, some druid changes, and too many others to list.

Read the patch notes and discuss the 1.10 changes (http://wow.forums.thedruidsgrove.org/showthread.php?p=130803).
