CentOS 8 has been released on September 24th, 2019. You now may be looking to try the world’s best opensource enterprise operating system. CentOS 8 is derived from the source of Red Hat Enterprise Linux 8 and uses Linux kernel 4.18.

There is a new distribution called CentOS stream,  a rolling-release Linux distro that sits between the upstream development in Fedora Linux and the downstream development for Red Hat Enterprise Linux. You can read about it on ContOS Stream release notes.
