cPanel & WHM versions 56 & 60 have reached End of Life and will no longer be supported by cPanel except when upgrading to a supported version.
In accordance with our EOL policy (https://go.cpanel.com/longtermsupport), 56 & 60 will continue functioning on servers where they are already installed. The last releases of cPanel & WHM version 56 & 60, 56.0.52 & 60.0.48, will remain on our mirrors indefinitely. However, no further updates, such as security fixes and installations, will be provided for versions 56 & 60. Older releases of cPanel & WHM Versions 56 & 60 will be removed from our mirrors.
We recommend that all customers migrate any existing installations of cPanel & WHM versions 56 & 60 to the most recent version of cPanel & WHM, version 68, which you can read about on https://releases.cpanel.com.
