There are too many changes to list between these versions,
but here's what's important for Nixpkgs:
- Enabled xen.efi building, allowing the nixos/xen module to
support EFI booting.
- Renamed xen-light to xen-slim, and removed the old xen-slim
package, as qemu-traditional has been removed per an upstream
recommendation.
- xen-slim (formerly xen-light) no longer builds iPXE.
- You can now use the OVMF from Xen's repos.
- Further generalised generic.nix. Maintaining three versions
at once is finally doable.
- Removed as many recursions as possible.
- Split the package output.
