Hi Nima,
as for 1) just look who did the last commit and bug that person to merge on his own. As for 2) I have the suspicion that it will be only Joel who pumped up the version number for the release, so we should be fine (did you make a diff, just to see what changed). We could then bump up the version number to 2.2b1 for dotlrn packages from 5.2.
Other than that: GREAT WORK!!!!!
Thanks a lot for this productive weekend.
