So Red Hat was getting closer and closer to CentOS. Then a few years ago, instead of being in partiy, Red Hat, and supposedly CentOS council, agreed it’d be better for CentOS to lead RHEL. This became CentOS Stream. And then the original creator of CentOS started Rocky. Alma was another distro that moved in to fill the niche of CentOS. I believe there are others as well.

CentOS Stream is closer to RHEL, but if I remember correctly, it’s rolling. So supposedly you as a developer could target CentOS Stream for RHEL’s NEXT major release and be ready when RHEL’s next major release gets to beta and you should be good to go.

I’ve never heard of ANYONE actually using or targetting CentOS Stream personally, but maybe there are folks. Pretty much everyone I know that was using CentOS in any kind of unofficial capacity has pivoted to Rocky or Alma or something else.
