CR Developer versions

Hi

Hoping for some clarity;

After some absence I have recently just reinstalled (CD Version) Crystal Reports Advantage 2008 CR Developer Version 12.0.0.683 on W7 64 bit machine and am trying to determine where I am in terms of the product updates.

A few hours trawling the forums/searches etc has left me none the wiser as even having found references to a service pack 5 can find not release notes.

Is this product still supported? Has it been superceeded? Are there product updates etc for it?

Could someone point me in the right direction please.

Thank You
