The PTR realm is now live and the PTR patch notes for Patch 3.1.0 are now available. You can read them in their entirety (courtesy of MMO Champion ) after the jump. They include the highly anticipated dual spec feature, a new Gear Manager to save gear sets for easy switching, and limited Ulduar testing. Also, ground mounts will now be able to swim. And here's a quote from Zarym regarding upcoming class changes:

The class changes are not nearly complete. We want to get the test realms out to begin testing the new content, but that means launching without all planned class changes ready. We're making numerous new class changes each day and will continue to add them in future PTR builds.

If you'd like to discuss the patch notes, Allakhazam user RPZip has started a thread in our general forum. Keep reading below for the full notes, which are subject to change as testing begins.
