I'm sure Derek will correct me if I am wrong. You should go ahead and create the DRUPAL-6--3 branch (but no tags), then the -dev from HEAD will go to that.

Subject: [development] dev release of contrib module using CVS HEAD

I maintain a contrib module with multiple branches in drupal.org CVS.

Until recently, my HEAD branch corresponded to the 2.x release.

Now, I've created a DRUPAL-6--2 branch for the 2.x release. HEAD is now
3.x.

My problem is that drupal.org gives me no way to change the version
associated with the HEAD branch. Right now, my project page offers two
releases both called "6.x-2.x-dev". One of those should be 6.x-3.x-dev.
How can I change it?

Thanks!
