Derived from and fully binary identical with the recently released SUSE Linux Enterprise 15 SP4 (Service Pack 4), openSUSE Leap 15.4 comes a year after the openSUSE Leap 15.3 release and it's powered by the Linux 5.14 kernel series, which is maintained by SUSE.
This release comes with a unified feature set, as well as a seamless migration experience for those who want to move their workloads from the commercial SUSE Linux Enterprise Server to the free openSUSE Leap operating system.
