I don't normally rush when it comes to upgrading services. MySQL 5.6 has been recently
released and I prefer until the RPM package has been included in most YUM repos and it
has been throughly tested. I still remember how painful was to install a new system with
MySQL (5.5 I believe) under Ubuntu last May. I had to report a bug and make some tweaks
in order to get the mysql service installed.
