ZFSBootMenu v2.2.2 contains no runtime changes relative to v2.2.1. The creation of UEFI bundles (so-called unified kernel images, or UKIs) in generate-zbm has been updated to properly support newer UEFI stub loaders that were known to cause boot failures in the past. These changes were inspired by similar functionality in mkinitcpio and the ukify utility included with systemd.
