Patch 2.1 is here

As announced yesterday, patch 2.1 has gone live this morning. It brings many, many changes; here are some highlights:
That's just the big stuff -- there's tons more. For well-organized compendia of 2.1 information, check MMO-Champion or World of Raids. The full patch notes are as usual available at Blizzard's site; if you can't get there, I have them mirrored on our site (in three parts, because the notes are ridiculously long: 1, 2, 3). And if you can't get the patch downloader to work, WoWWiki has a list of patch mirrors.

Most realms were supposed to come back up at 11:00 AM PDT; there was a bit of a delay, although most realms appear to be up now. However, some realms needed extended maintenance, and are expected to come up at 2:00 PM PDT. Those realms are listed after the cut.
