Only 18 months ago, IBM bought Red Hat. Now, according to their latest announcement on Tuesday, they shift focus from CentOS Linux to CentOS Stream. The most recent release of CentOS Linux 8 is going to be EOL by the end of the 2021.
(EDITED on December 9, 2020). As you probably already know CentOS 6 is reaching its End Of Life in November of this year. So if you still have a distribution of CentOS 6 it’s high time to upgrade.
