Ben Cotton 82eac3
CentOS Stream is a distribution that community members can use to take advantage of a stable ABI/API for development and testing, while still seeing some updates on an accelerated basis.

Note: CentOS Stream does not include container images.
Ben Cotton 82eac3
The current recommendation is to use Red Hat Universal Base Image (UBI) and include centos-release-stream (link coming!).

##What happens when CentOS Stream switches from RHEL 8 to RHEL 9 based content?
Ben Cotton 82eac3
Ben Cotton 82eac3
Around the time the RHEL 9 Public Beta is issued, an additional set of CentOS Stream repositories and ISOs will be available.
Ben Cotton 82eac3
The existing CentOS Stream repositories representing RHEL 8 bits will continue to be available, and changes to these bits will continue as before, until approximately one year after the general availability of RHEL 9.
Ben Cotton 82eac3
At that time, the older repositories will be discontinued, although sources will continue to be available.
Ben Cotton 82eac3
Ben Cotton 82eac3
As the cut-over approaches, Red Hat will evaluate the situation at that time to determine how long the overlap will be.
Ben Cotton 82eac3
CentOS Stream is envisioned for primary use in situations where pinning to a specific set of binaries for the long-term is not required.
Ben Cotton 82eac3
Therefore the goal of the overlap is to serve either specific development needs or to allow for time for testing and upgrades.

##What does this mean for CentOS Linux?
Ben Cotton 82eac3
Ben Cotton 82eac3
CentOS Stream is separate from CentOS Linux.
