The HTTPS clone works also with the rtems.org server, but it lacks user 
feedback and is quite slow.

For some users the Github mirror is currently the only stable way to 
clone the RTEMS repositories.

Even with frequent releases, I would recommend to clone the Git 
repositories. I thought that a release is just a certain Git commit (the 
only one with the release version) with a bootstrap packed as an archive?
