  CentOS Stream
  CentOS Stream is a "continuously delivered distro that tracks just ahead of Red Hat Enterprise Linux (RHEL) development, positioned as a midstream between Fedora Linux and RHEL." which is designed for "anyone interested in participating and collaborating in the RHEL ecosystem".
  Because prior CentOS releases were derived directly from RHEL (RHEL was essentially upstream of CentOS), Stream thus represents a change from prior CentOS releases, being situated between the upstream development in Fedora and the downstream development for RHEL. That said, CentOS Stream 9 and RHEL 9 started from the same codebase and thus CentOS Stream could reasonably be seen as "closer" to RHEL than Fedora.
  The initial release, CentOS Stream 8, was released on 24 September 2019, at the same time as CentOS 8. As CentOS 8 became unsupported, The CentOS Project provided a simple means of converting from CentOS Linux 8 to CentOS Stream 8.
