vb3 beta 6 is relatively stable, that's why we decided to upgrade now. as the reindexing of all stats/searchindex... did take a very long time on the testboard i'm glad we can upgrade in more than one step
The fact, that we upgraded has nothing to to with the fact that vb3 hacks are currently not allowed to be released. You'll find the answer to that question on vb.com, too.
As a hint: purplestyle uses the vb3 images, so there shouldn't be any missing things
