The openSUSE project reminded its users that openSUSE Leap 42.3 will reach the end of its development cycle on June 30, 2019, recommending that they prepare to upgrade to openSUSE Leap 15.1.
Released on July 26, 2017, openSUSE Leap 42.3 is based on SUSE Linux Enterprise 12 Service Pack 3 Powered by Linux Kernel 4.4 series.
Initially, this version would be supported until January 2019, but the openSUSE project decided to extend its development cycle for a further six months to give users time to upgrade to openSUSE Leap 15.
Now that openSUSE Leap 15.1 is the latest release of openSUSE Leap, it's time for openSUSE Leap 42.3 users to update their installations and they have one month to do that, until June 30, 2019.
