Official web site :

This new major version will be available in the official updates for fedora or in EPEL-6. The package available in my repository also provides the official and compatible themes (even if this is against the packaging Guidelines : 1 source = 1 package). So, it is available for fedora 11 to 17 and enterprise linux 5 to 6 (if you have the minimal required php version, also available in the repository).

As always :
yum --enablerepo=remi install phpMyAdmin

Discover this new version which come with a lot of new features (ajax, chart, preferences, ...), and post your feedback.
