tomscharbach 5.4 Leap, newly released, will be supported until November 2023
openSUSE and SLE
Yes. That's what the article I mentioned suggested as well. It also said that 5.5 Leap would be the end of Leap. I couldn't find an easy way to link to this, so here's a copy (emphasis mine):
"While much attention this week is focused on openSUSE 15.4 Leap, many in the openSUSE community have concerns about the future of this branch of their distribution. openSUSE 15.4 is the penultimate release of Leap and it looks like 15.5, likely to be released next year, will be the last of the line. Much of this concern has come in the wake of an announcement from Lubos Kocman which read, in part: "Since the announcement of next-gen SUSE Linux Enterprise has already landed, I'd like to take a moment and talk a bit about our last openSUSE Leap 15.X release and set some expectations."
"Stefan Behlert has stated the next release of SUSE Linux Enterprise will look a lot different than the current offering, which shares its code base with Leap. "The connection between Leap and SLE has changed. And while some bits and pieces got better, we firmly believe we can do better. SLE 15 is a great general purpose operating system, yet challenges with some use cases, new places of deployment, and the type of enhancement requests show that it's time for a successor."
