Other general things I’m seeing in the tree (may need both SUPPORT.md and changelog updates):

* Support for zstd-compressed dom0 kernels
* vmtrace support
* named PCI devices in xl / libxl
* gnttab stupport for NetBSD
* viridian: Better virtualized IPI support, cpu hotplug, removal of 64-vcpu limit
* x86_emulate support for AVX-VNNI
* Expanded test-cases for x86_emulate
* HVM-specific MM code (shadow, p2m) code factored out into a separate file
* hypfs: Added cpupool directories and controls

Could probably use some input on the naming here from people who have contributed.

More things:

* Something about MSRs?
* CI loop: Added Ubuntu focal, alpine linux targets
* CI loop: Added “artifacts” support for more efficient testing
* CI loop: Added dom0less, alpine Linux dom0 tests

Again, this is just me trying to guess from skimming the changelog.

I guess that's rather something which needs mentioning in release notes.

This is inaccurate. Linux device model stubdomains went into 4.14, but
SUPPORT.md was only updated in 4.15.  Patch 2/3 removed "libxl support
for running qemu-xen device model in a linux stubdomain."

This was a downgrade iirc (by XSA-363).

Nit: This line looks overly long.
