> Squash and rebase are functionally identical in this case. Sorry, but for me `git merge --squash` doesn't work. Currently, I have a global option --no-ff for master $ git config branch.master.mergeoptions --no-ff In this way `git merge --squash` crashes with message > fatal: options '--squash' and '--no-ff.' cannot be used together In other way it writes something like > Fast-forward > Squash commit -- not updating HEAD and... not updates parent branch. For example, GitHub propose for PR's: - Create a merge commit - the same as `git merge --no-ff` - Rebase and merge - the same as `git rebase ...; git merge --ff-only` - Squash AND commit - like two different operations. So after squash we still have to merge our commit properly into parent branch. The new option just dynamically selects between --ff and --no-ff for `git merge`. Nothing else. -- Ruslan
