DO NOT DOWNLOAD THEM!
Apparently Curse moderators took it upon themselves to claim some Ace2 addons are 3.0.2 compatible when they are not without permission from the authors. DO NOT DOWNLOAD THEM as updates. They will error on you.
GOOOOOOOOOOOO curse!
I've been lucky enough to find a few of the oddball addons i haven't heard of anyone else using by going to the developers' sites directly. Many of them it seems are now using a number of free/virtually free hosting options to distribute their code such as google code. I'm glad to see many of the addon developers continuing to update and make available to the public their hard work in spite of the Ace/Curse situation forced upon them. Granted...i haven't had a chance to test any of them yet.
