No security patches would be issued for this release in the future.
Version-Release number of selected component (if applicable):
yum list mysql*
Steps to Reproduce:
1. yum list mysql*
2. watch for mysql-packages
3. notice only 5.1-packages there
only packages flagged with version number 5.1 present
mysql in version 5.5 present as on RHEL 5.10 or on RHEL 7.0 - whereas there it is mariadb albeit in version 5.5, too.
MySQL 5.5 is unfortunately not compatible with 5.1, so upgrading is not possible withing RHEL-6. MariaDB 5.5 is included in RHEL-7 then.
Howerver, MySQL 5.5, as well as MariaDB 5.5, are now available as part of Red Hat Software Collections (RHSCL) V1.0, now V1.1 is also released. It is included as part of most RHEL subscriptions.
