[CentOS] Support policy CentOS 5

Hi list

Can someone tell me what the exact CentOS policy for end-of-life is for 5.0?

Let me explain: I have been using RHEL for a number of years and had to
switch to Fedora for installing some packages only supported under F6.

As I find Fedora's policy for release life duration too stringent (and I
do no longer need the packages that made me choose F6), I'm considering
switching over to CentOS5.0
I know, 5.0 is not the most recent release, but that one is supported by
Parallel Pro (new package I need)

Thanks
