Use in conjunction with repo updates-testing

The [updates] repository only keeps the last versión of the package, so to use yum downgrade reliably you should enable [updates-testing] repository and issue a yum update ... and then, if it does not work, you can rollback to the previous version in [updates] or in [fedora] repo with yum downgrade ....
Another alternative is to keep a local repository with these versions with yum-plugin-local extension.
