Last week Red Hat made a fundamental change to their plan with CentOS, dramatically changing both the tracking of RHEL and the end of life, which went from 2029 to 2021. CentOS is going to become CentOS Stream, which means it's now on an upstream continual release schedule. This means CentOS is now a preview of what's to come in RHEL rather than a community edition of existing RHEL builds. Enterprises that rely on a stable Linux distribution that mirrors RHEL, will have to make a change away from CentOS soon.
