Percona yum Testing Repository
Percona offers pre-release builds from our testing repository. To subscribe to the testing repository, you’ll need to enable the testing repository in /etc/yum.repos.d/percona-release.repo. To do so, set both percona-testing-$basearch and percona-testing-noarch to enabled = 1 (Note that there are 3 sections in this file: release, testing and experimental - in this case it is the second section that requires updating). NOTE: You’ll need to install the Percona repository first (ref above) if this hasn’t been done already.
