Why is Netware 6.5 sp6 labeled evaluation?

Is sp6 still in beta or testing?

Am I looking at this wrong?

I am currently on Netware 6.5 sp5 and am looking to go to sp6 and whatever
post-patches are required.

Should I install sp6? Where do I download disks?

SP5 is very stable!!!! Good job with SP5!!!! Some servers running over
200 days!!!!

Also need to know if there is any compeling reason to move to sp6 at this
