phpMyAdmin-4.2.6 requires MySQL-5.5, what should we do on CentOS 6?

Dear all,

Since phpMyAdmin-4.2.3, it enforces the minimum PHP (5.3) and MySQL (5.5) versions, but RHEL/CentOS 6 ships MySQL-5.1.x, so we can NOT use the latest phpMyAdmin-4.2.6 on RHEL/CentOS 6.

Here comes the question, on RHEL/CentOS 6, which choice do you prefer?

1. Ship phpMyAdmin-4.2.2 which has known bugs and security issues, because it works with MySQL-5.1.x. And allow public access from external network.

2. Ship phpMyAdmin-4.2.2 and restrict access to 127.0.0.1 by default.

3. Don't provide phpMyAdmin in iRedMail

Also, some addition questions:

*) Do you use it frequently or rarely?
*) Is it hard for you to install phpMyAdmin (or other tools) manually?
*) Do you prefer to use a desktop application to connect to SQL database for management or a web application running on your server?
*) Are you satisfied to run a out-of-date phpMyAdmin version which has known bugs and security issues on your server?

NOTE: This applies only on RHEL/CentOS 6.
