Vbulletin has announced that they will no longer be updating vbulletin 3.0 and 3.5

It does make sense as they might be spending a lot of time fixing old bugs for older versions rather than improving vbulletin for newer features.

They will also be increasing the price of vbulletin. So for those who haven’t bought a vbulletin license yet I would recommend getting it before they officially increase the price.
They also will not be asking for recurring fees for addons for vbulletin. Which is a nice outcome of this.
