Evil, I know but:
git tag -d v1.0.0-beta.4
git tag -a v1.0.0-beta.4 -m "Examples for Substance 1.0 Beta 4 release."
git push -f --tags
When you want to rebase onto a force-pushed branch.
git rebase --onto new_base old_base mybranch
This selects the commits between old_base and mybranch and replays them on top of new_base.
