[CentOS] 4.2 upgrade and kernels

Just curious about kernel requirements after the upgrade. I've been running the 2.6.9-11.106.unsupported kernel for some time. Now I see that the base kernel is up to 2.6.9-22.EL.

Are there any plans to upgrade the unsupported kernel? Should I be using the newer kernel after the upgrade? Does it make any difference?

Not trying to be pushy; just looking for information.

Thanks for all the good work, and tons of it.
