An update with a little bit of bad news. It's impossible to meaningfully migrate the branches into the split-off repositories. The reasons are: 1) the build on those release branches won't be able to cope with being split-off, unless I manually fix them one by one (= big changes, very impractical) 2) the git command to split-up the repository doesn't support it if a split-off repositories contains multiple directories. *So, branches/tags will not be migrated to the split-off repositories.* All history of master will be migrated. The 4 topic branches (lr_unlinking_20101116, ...) will need to be manually migrated by their owners. Sorry. The monolithic droolsjbpm git repository will be kept around for a short time to give them the time to do this. The 5 community release branches (up to 5.1.x) will be moved back to subversion (to rejoin their SOA release branch brothers), so we can remove the monolithic droolsjbpm git repository before it causes to much confusion. The community release branch 5.2.0.M1.x will be lost.

We don't really need the 5.2.0.M1.x branch if we have the tag, but I have a feeling that we will lose that one too. We don't usually need the minor release branches or tags after the release, but they are nice to have. The M1 is codes are saved in the src.zip in our downloads page. So if somebody needs them they can get them from there.
