Red Hat Enterprise Linux 8 (RHEL 8) was released officially on 2019-05-07. I know everyone, including myself, is eagerly waiting for the GA release CentOS 8 to install and play with the new features that come with it.
The CentOS 8 development team is currently committed to rebuilding CentOS 8 Linux distribution from RHEL 8 code base. As RHEL 8 is based on a much newer version of Fedora than previous versions, this means there is more work to be done around CentOS 8 installer, packages, packaging, and build systems before we can get the final product.
To keep you updated, the development team have created a status Wiki page that you can use to track development progress. Here is the link to it.
This article will be updated when CentOS 8.0 release is available for general use.
