CentOS Linux 8.0-1905 has been released. The release
notes have more details. The CentOS project also introduces CentOS
Stream. “CentOS Stream is a rolling-release Linux distro that
exists as a
midstream between the upstream development in Fedora Linux and the
downstream development for Red Hat Enterprise Linux (RHEL). It is a
cleared-path to contributing into future minor releases of RHEL while
interacting with Red Hat and other open source developers. This pairs
nicely with the existing contribution path in Fedora for future major
releases of RHEL.“
