Red Hat and CentOS Roadmap Changes
Red Hat and CentOS announced that the lifecycle of the CentOS Linux 8 operating system has been cut short and CentOS Linux 8 – as a rebuild of RHEL 8 – will end December 2021. Red Hat and CentOS have announced several significant changes to the CentOS Linux roadmap that may affect your PostgreSQL deployments.
Red Hat revealed it would be shifting focus from CentOS Linux to CentOS Stream. CentOS Stream is not a replacement for CentOS Linux; it tracks just ahead of a current RHEL release serving as its upstream (development) branch. The news around CentOS Stream is new and evolving. Red Hat mentions CentOS Stream as a “rolling preview” of RHEL and recommends that its customers use Red Hat Enterprise Linux for production deployments. EDB will continue to monitor progress and adoption around CentOS Stream and will provide more information by Q3 2021.
