Articulate '09 patch release

Every so often I receive a message when I start up PowerPoint (2003) that there is a new version of Articulate Studio available. 

I am currently running Presenter '09 version 6.2.907.1413 Pro

Is there a patch release of Studio '09 that I should install or is the message I receive just trying to tease me about Studio '12 coming soon?

Thanks!
