If you've been waiting for the 2.3.2 Public Test Realms to come back up again, you're definitely in luck. Hortus has announced the return of the PTRs, though it comes with some additional announcements World of Warcraft players should all know about.

First off, Hortus has also announced that the PTR authentication servers were not updated between 2.3 and 2.3.2. This means that only those folks who recently changed their passwords or who were ineligible for PTR duties before October 8 will not be allowed onto the PTRs.

Second, and perhaps more importantly for all of those folks who're eligible, there are premade characters for your use! As Hortus notes, "You can copy 4 per account on the PTR character copy page. They have Season 2 and heroic gear. There will be no changes to the premades for this test push."

Third, Warlocks currently have a bugged Seed of Corruption spell, and Blizzard is working hard to try and fix the problem.

Lastly, the patch notes you picked up for 2.3.2 build 7705 are the mostly-final patch notes, though some things in the notes will be implemented in a later build.
