Hello!
With the opening of the new 0.3.3.x branch, the git master branch for tor is now 0.3.3.x. Feature patches should still be based on master. If you are writing any bugfix patch that should go into an earlier version, please base it on the appropriate maint branch. For example, if you're fixing a bug in Tor 0.3.2.x, you should base your git branch on the "maint-0.3.2" branch.
best wishes,
