[keycloak-dev] map Red Hat Single Sign-On version to git tag

I've got "Red Hat Single Sign-On - Version 7.0.0.GA" installed and I need to see the source code matching that version. Normally I would look at the git tags to find a release but there doesn't seem to be a tag related to this release. How do I map what is in version.txt to a git tag? Is there a document somewhere? What is the matching tag for "Red Hat Single Sign-On - Version 7.0.0.GA" -- John
