Pending review by Unity. Not sure if it will take longer over the holiday weekend, but it's normally up pretty quickly.
NOTE: 1.2 is a big update with lots of changes, so PLEASE BACKUP YOUR PROJECTS BEFORE IMPORTING THE UPDATE!!
There are a couple of things that didn't quite make it into 1.2, so we're already working on a 1.2.1. Please report any problems you have with 1.2 so we can address them quickly in 1.2.1.
Thanks!
