$git checkout -b release-3.4 origin/release-3.4rfc.sh is being updated to send patches to the appropriate branch. The plan is to have all 3.4.x releases happen off this branch. If you need any fix to be part of a 3.4.x release, please send out a backport of the same from master to release-3.4 after it has been accepted in master.
Thanks, Vijay
