Not only we merge it on master, we do a tag on it as well. Now to get the history/branch back you can always checkout the tag: git checkout <tag> and see the history: git log --graph --decorate --pretty=oneline --abbrev-commit —all So, it’s safe to delete a branch when it’s merged to a target/master branch. If you have never deleted a feature branch once it was merged, you should try and see for yourself. At the end of the day, git is all but link-list logic at the core. The branch too tracks just the HEAD, if you’ve refs/tag/sha of a branch you can checkout to get the branch back. When a branch is merged, git allows you do delete the branch with: git branch -d <release>, if branch is not merged you’ve to force it with -D: git branch -D <release> To cut a maintenance release from a release version, all you’ll have to do it: git checkout -b <support-branch> <tag> HTH. > I think the model the article proposes, fits the products like SAS, when > there are no maintenance releases and support is provided just for the > latest release.
