Ignoring git for a moment our setup is that each major version (9.6) gets a branch when it is finally released. For each minor release the last commit on each branch that is included in the release is tagged with both the branch/major-version AND the patch/minor-version. I'm sure the internet can provide a better overview of the differences, within git, between tags and branches. One way to look at it, though is that tags are explicit labels pointing to commits whereas b ranches are implicit labels. When you do: git checkout branch you are asking for whatever HEAD - for that branch - points to. Committing to a branch causes a new commit to be created and then HEAD - for that branch - to be moved. So you are, by default, dealing with the implicit HEAD label within the branch "namespace".
