cPanel & WHM 11.50 has now reached End of Life, and cPanel & WHM 11.52 is set to reach End of Life at the end of September 2016.
In accordance with our EOL policy [https://go.cpanel.net/longtermsupport], 11.50 will continue functioning on servers where it is already installed. The last release of cPanel & WHM version 11.50, 184.108.40.206, will remain on our mirrors indefinitely. However, no further updates, such as security fixes and installations, will be provided for 11.50. Older releases of cPanel & WHM 11.50 will be removed from our mirrors.
Additionally, cPanel & WHM version 11.52 is set to reach End of Life at the end of September 2016.
We recommend that all customers migrate any existing installations of cPanel & WHM version 11.50 or 11.52 to newer version 54 or 56. 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.net/blockers), then cPanel is here to help.
