Launched on July 26, 2017, the OpenSuSE Leap 42.3 operating system is based on SUSE Linux Enterprise (SLE) 12 Service Pack (SP) 3 and the long-term supported Linux 4.4 kernel series. Like previous openSUSE Leap 42 point releases, openSUSE Leap 42.3 was supposed to receive 18 months of support, until January 2019. However, both the openSUSE Project and parent company SUSE decided to give users more time to upgrade to the latest openSUSE Leap 15 release, which is based on the SUSE Linux Enterprise (SLE) 15 operating system series, by continuing to deliver updates to the openSUSE Leap 42.3 release, and the openSUSE Leap 42 series, for six more months.
