Several pre-order questions
 

Hello! Finally I decide to migrate on vBulletin from SMF 2.0, but I have several questions before I buy licence.

1) Is I right undertund that new 4.0 version are a bit buggy right now and unstable to use for big projects (I have more then 700 users online)?
2) If I will choose 3.8.5 stable version to use, can I be sure in receiving updates/but fixes and so one, or after 4 version will be more "stable" company will cancel provide updates for 3.x.x version?

Thanks for any comments!
