The Phoronix Forums have just been upgraded to vBulletin v3.6.0 from the previous v3.5.4. The vBulletin 3.6 branch was officially released last week. I just ran through the updates, and rebuilt the forum information for the new update, and it looks like all is running smooth.
However, there could be things that are still being overlooked, so if anyone runs into any vBulletin problems, please report them. Thanks.
