Create a signed tag (tags/v<VERSION>) on the "master" branch (for major
releases) or the "support" branch (for minor releases).

    $ git tag -u EE8E0720 -m "Version <VERSION>" v<VERSION>

Push the tag.

    $ git push --tags

For major releases: Create a new "support" branch:

    $ git checkout master
    $ git checkout -b support/2.4
    $ git push -u origin support/2.4

For minor releases: Push the support branch, cherry-pick the release commit
into master and merge the support branch:

    $ git push -u origin support/2.4
    $ git checkout master
    $ git cherry-pick support/2.4
    $ git merge --strategy=ours support/2.4
    $ git push origin master
