Ok so 3.1 dropped today and I was able to download a ton of updated addons thanks to the curse client. I only had to turn off Gatherer and SKG(Client side of our guild loot mod) neither of which really apply to the UI as a whole.
I was then able to get into Ulduar 25 and test it out. We downed Flame Leviathan tonight in 3 shots! Then we went into the 10 man version and killed him again!
So far no errors with the major addons that make up the UI. Im going to give it one more night tomorrow to ensure everything is still error free.
Expect a download up for the new version of my UI on Thrusday.
