As an EasyApache 4 user, it is expected that you are able to deploy applications using a supported version of Ruby, and as such, there is a plan underway to upgrade EasyApache to a newer version of Ruby (2.6/2.7).
As part of the plan, new applications use the new, supported version and old applications continue to use the older version in order to ensure continued compatibility.
Since this is an ongoing project, it requires all the Ruby-related packages in our repositories to reflect the new changes. Therefore, there might be some Ruby-related packages that have not yet been published in our repositories for CentOS 8 and Cloudlinux 8. However, this plan is been actively worked on by our developers and these packages will be added to our repositories in the near future.
This is tentatively planned for cPanel version 94.
