+https://github.com/maxximino/grub2/commit/f12806f43a969a654dee7bb89b2e8fd5c42f0e2e
+
+A minor change was made to account for d8a0feb6 from upstream. This change
+prevents a compile time failure that is caused by a change in the callback
+interface used by mzap_interate().
+
+The initial feature flag support patches were written by Delphix while the LZ4
+support was written by Saso Kiselkov. The work porting this to GRUB2 was done
+by Massimo Maggi, while the adaption to Gentoo's GRUB2 package was done by
+Richard Yao.
