Rocky Linux

Rocky Linux is the idea of a Linux distribution to replace CentOS. The idea was born after Red Hat decided not to honor the decision to provide full updates for CentOS 8 until 2024 and maintainence updates until 2029 as initially announced.
Gregory Kurtzer, founder of the CentOS project made this announcement and the community is actively working on the project.
Change in End of life for CentOS 8.
CentOS was acquired by Red Hat in 2014. On December 8, 2020, it was announced that the CentOS project, previously a downstream branch of Red Hat Enterprise Linux, would be moving to CentOS Stream, an upstream development branch of RHEL. 
The maintenance schedule for CentOS 8 was also changed, ending full updates and maintenance updates on December 31, 2021. As an aside, the maintenance schedule for CentOS 7 is unchanged, with maintenance updates ending on June 30, 2024.
