CentOS Stream
Rolling preview branch ahead of RHEL—where Red Hat lands changes before they freeze in a major RHEL release.
Why it is included
Important to understand the modern RHEL pipeline; useful for contributors and early adopters validating upcoming RHEL behavior.
Best for
Developers and CI that want to track the next RHEL without a subscription.
Strengths
- Upstream of RHEL
- Predictable integration point for Fedora→RHEL
Limitations
- Not a traditional ‘stable CentOS Linux’ replacement for every workload
