The basis for the open-source Linux distribution CentOS 7.9.2009 is now Red Hat Enterprise Linux 7.9, which was released at the end of September.
The CentOS project creates an (almost) complete copy from the source code packages of the commercial Red Hat Enterprise Linux. CentOS carries the release date in the version number. For example, CentOS 7.9.2009 uses the source code published by Red Hat in September 2020.
News from RHEL 7.9
The distribution also contains all new features from RHEL 7.9, which, as usual, are extremely manageable. The Performance Co-Pilot (PCP) now also records “per-thread” metrics. The MariaDB database, the System Security Services daemon SSSD and the cluster manager Pacemaker are included as bug-fixed versions. All changes are revealed in the RHEL 7.9 release notes, which also apply without restriction to CentOS.
The CentOS developers essentially only change the branding for their distribution. This manifests itself, for example, in a different background image. The official “CentOS-7 (2009) Release Notes” ready.
Processor architecture support
Older CentOS 7 installations are updated with the command “yum update” to the 2009 version. The latter also replaces all previous versions from the 7.x series, which is why the CentOS developers recommend an update. Just like RHEL 7, version 7 of CentOS will also be supported until June 30, 2024.
The newer CentOS 8, which in turn is based on Red Hat Enterprise Linux 8, has been available since last year. The CentOS version 7.9.2009 is primarily aimed at users who are still using CentOS 7 or who use a system with i386, ARM32 or PPC64 architecture. CentOS 8 no longer supports these three processor architectures.
