One of the key differences between CentOS 7 and CentOS 8 is the new version of the YUM package manager. YUM stands for Yellowdog Updater-Modified, and has been the package manager for CentOS for many years. This package manager allows users to modify, install, and manage packages used for software installation and execution. In CentOS 8, YUM was upgraded to the DNF package manager. While CentOS 8 is the most recent version of CentOS, it is important to note that it will no longer have official support by the end of 2021.ĭNF stands for Dandified-Yum, and this upgrade retains much of the functionality of YUM while offering increased performance and reduced RAM usage. At that time, CentOS will be continued in the form of CentOS Stream. Current users of CentOS 8 (also known as CentOS Linux), will need to switch to RHEL or CentOS Stream in order to continue receiving support for those platforms. What is CentOS Stream?ĬentOS Stream is the upstream development platform for RHEL, taking the place of CentOS 8.
