In December 2020, CentOS announced on their blog the future of the CentOS Project is CentOS Stream serving as the upstream (development) branch of Red Hat Enterprise Linux.
At least 2 RHEL forks have been announced and seem to be worth checking out:
Rocky Linux (release candidate available)
AlmaLinux OS (stable release already available)
Also… you can try CentOS Stream 🙂
Later Edit: This article was updated May 3, 2021 after Rocky Linux announced the availability of their release.
