Released two years ago, on July 26th, 2017, the openSUSE Leap 42.3 operating system was the third maintenance update to the openSUSE Leap 42 series, which is also the last to be based on the SUSE Linux Enterprise (SLE) 12 operating system series. openSUSE Leap 42.3 was based on the packages from SUSE Linux Enterprise 12 Service Pack 3 and was powered by the long-term supported Linux 4.4 kernel series. It was initially supposed to be supported until January 2019, but the openSUSE and SUSE projects decided to give users more time to upgrade to the major openSUSE Leap 15 series.
