scientific data processing, and many more.

CentOS Stream defines Enterprise Linux.
Shaun McCance 4f8721
Shaun McCance 4f8721
CentOS Stream is derived from Fedora Linux.
Shaun McCance 4f8721
It has a new major version release every three years,
Shaun McCance 4f8721
and each release is maintained for five years, matching the
Shaun McCance 4f8721
[full support phase](https://access.redhat.com/support/policy/updates/errata)
Shaun McCance 4f8721
of RHEL.
Shaun McCance afaef1
CentOS Stream development is open to all, but because CentOS Stream only
Shaun McCance afaef1
has updates intended for RHEL, it is maintained by the RHEL team.
