Yesterday I branched for the Bugzilla 3.2 development. Moving forward, the tip will slowly be converting to the Bugzilla 3.2 codebase while the branch will stick to 3.0.x code.
This is an experiment for me to see if I, in all my ADHD glory, can manage to keep two active branches of development going simultaneously. For those of you interested, the TESTOPIA_2-1_BRANCH is the branch name in CVS.
Right now my thinking is that this will be kept up to date for Bugzilla 3.0.x primarily for bug fixes while new development and new features will stay on the tip. I guess it will depend on how much has to change between Bugzilla 3.0 and 3.2 in the areas where Testopia hooks or patches in. Where a clean patch can be applied, it won't hurt to have new features on both.
