About to ugrade to vB v.4 - any issues with VBSEO?

The title says it all, really.
I'm a bit worried as the upgrade seems rather more serious than the usual security upgrades.

Hi Bankfodder,

vBSEO 3.5, which supports vBulletin 4.0, is currently in RC2 stage. While we don't recommend running non-Gold software on a production site, many people (including myself) are, with little to no issue.

Going to vB4 is a major step, have you created a testbed to play with it? We can issue a temporary testing vBSEO license if needed. Just put in a Support Ticket to request.

Thanks
