cPanel & WHM Version 54 Now EOL, Cent 5 & Cent 6-32bit in 3 Months
cPanel & WHM version 54 has reached End of Life. In accordance with our EOL policy (https://go.cpanel.com/longtermsupport) 54 will continue functioning on servers where it is already installed. The last release of cPanel & WHM version 54, build 54.0.36, will remain on our mirrors indefinitely. However, no further updates, such as security fixes and installations, will be provided for 54. Older releases of cPanel & WHM 54 will be removed from our mirrors.
cPanel & WHM version 56 will reach End of Life at the end of April 2016. You can read more about that in the cPanel blog post from last year: https://blog.cpanel.com/end-of-life-for-centos5/
We recommend that all customers migrate any existing installations of cPanel & WHM 54 to version 62, which you can read more about at the cPanel release site https://releases.cpanel.com
If your server setup complicates the process of migrating to a newer version of cPanel & WHM (an upgrade blocker list is available at https://go.cpanel.com/blockers), then cPanel is here to help. Simply open a support ticket at https://tickets.cpanel.net/submit so that our knowledgeable support team can provide recommendations, migration assistance, and more.
