better wording IMO: "libvirt probes the underlying platform in order to fill in these SEV attributes automatically before launching a guest." Regards, Erik

The news comes from "5422f60e2f virt-aa-helper: allow hard links for mounts" In my understanding, it means apparmor allows the guest to create hard links on shared file system like 9pfs

That would be a 'bugfix' at best. IMO it's not really worth documenting. If you do think it's worth mentioning, put it into the 'Bug fixes' section and make sure to mention that it's to do with shared filesystems using p9fs, otherwise it's too vague to help anybody.

NACK, checkpoints as part of incremental backups are still not enabled due to the missing 'blockdev-reopen' capability of qemu, so there's no point in documenting this.
