The CentOS Project announced the availability of CentOS Stream 9 in a blog post that lays out what Stream is supposed to be in the Enterprise Linux ecosystem.
There is also a page on the site dedicated to what’s happening in Stream 9.
The question What is CentOS Stream? is answered in the first paragraph of the announcement:
CentOS Stream is a continuous-delivery distribution providing each point-release of Red Hat Enterprise Linux (RHEL). Before a package is formally introduced to CentOS Stream, it undergoes a battery of tests and checks — both automated and manual — to ensure it meets the stringent standards for inclusion in RHEL. Updates posted to Stream are identical to those posted to the unreleased minor version of RHEL. The aim? For CentOS Stream to be as fundamentally stable as RHEL itself.
Sounds pretty good to me. The announcement is a must-read, so do.
There isn’t much there just yet, but hopefully developers for Fedora and EPEL — which stands for Extra Packages for Enterprise Linux — can start building everything for EPEL 9.
For me, EPEL is the secret sauce of Enterprise Linux (CentOS, RHEL and all clones). There are so many things you can’t do without it.
And even though it’sfinally a Flatpak, I want to thank Carl for building an EPEL 8 package of gThumb for me when it was the missing piece in my CentOS Stream 8 workflow.
