For the previous releases, this was almost entirely done by Tom. But he is a bit swamped in his PVM work at the moment.
I will be looking into the next release as one of my upcoming tasks and I can use every bit of help available.
It involves going over all the bugs (not the new features for a service release), looking if they are really bugs, validating them wether we will fix them or not or if they possibly have been fixed already, fixing them if necessary (according to their importance) and then releasing the new release.
Simple huh ;-)
