Git Tag

Major Releases: Commit these changes to the master branch.

Minor Releases: Commit changes to the support branch.

git commit -v -a -m "Release version $VERSION"

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

git tag -s -m "Version $VERSION" v$VERSION

Push the tag:

git push --tags

For major releases: Create a new support branch:

git checkout master
git push

git checkout -b support/2.11
git push -u origin support/2.11

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

git push -u origin support/2.10
git checkout master
git cherry-pick support/2.10
git merge --strategy=ours support/2.10
git push origin master
