The openSUSE project has released Leap 16, its first major release since openSUSE Leap 15 in May 2018. This release brings some changes to the core of the distribution aside from the usual software upgrades; YaST has been retired, SELinux has replaced AppArmor as the default mandatory access control (MAC) system, and more.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

All of YaST is deprecated because it was too difficult to maintain, and the devs are constantly telling people to stop using it over on the official forums. We're supposed to have switched to Cockpit and Myrlyn by now.
I had no idea! It seems like it was a really unruly project to manage, but it's a shame to lose the centralization of having one app that can configure anything. I don't see any problem in having package management split off into Myrlyn, but it sounds like Cockpit is much more limited in scope, which is a shame, since handling the edge cases gracefully was what made YaST so useful.
