SUSE Enterprise Server (SLES) 15 SP3 has been released in June 2021.
It is the first of the two enterprise platforms to move to a 5.x kernel.
RHEL 9 is currently in beta and also comes with a 5.x kernel.
Most other plaforms (Debian, Ubuntu, PhotonOS) already moved to a 5.x kernel a while ago. The only platform missing is RHEL. But they are on a good way.
Beginning with SP3, SLES and OpenSUSE Leap are source code and binary compatible, which might make it a new interesting platform for customers.
IMHO having the 5.x kernel supported in Domino 12.0.1 would be important!.
See details below for the SLES / OpenSUSE Leap compatibility.

This is the first release that provides binary compatibility with the latest openSUSE Leap release:
"With the release of SLES 15 SP3 we now have 100% binary compatibility with openSUSE Leap 15.3 (our developer platform).
That means that you can smoothly move workloads from development to production environments that run SLE 15 SP3 - and back again - with assured application compatibility.
This is an important milestone for openSUSE and SUSE, our users and our customers: Leap 15.3 is the first release where openSUSE Leap and SUSE Linux Enterprise share the same source code and use the exact same binary packages.
The bottom line is that we are providing a seamless developer experience that drives faster digital transformation."
Changed from SUSE to CentOS a few years ago - so agree on kernel 5, but have no feelings for SUSE :-)
