Reverts change from tagged versions to sha.
Removes tag ambiguity on what version a sha points to when multiple tags available.
Makes comparing versions from previous releases more straight forward, without parsing potentially incorrect comment.
Fixes sync issue between tag in comment and sha, the selinux comment was incorrect here.
Updates reflect2 library to correctly tagged version, includes global variable fix.
