+- Added a cache to all the filesystem drivers except for ext2fs. This cache
+ greatly improves performance in VirtualBox, and offers modest performance
+ improvements on a few "real" computers. The ext2fs driver loads blocks in
+ a strange non-linear fashion that causes the cache to degrade
+ performance, so I've disabled the cache for ext2fs. (Ext4fs doesn't
+ suffer from this problem.)
+- Filter boot loaders based on a test of their validity; keeps out Linux
+ kernels without EFI stub loader code, loaders for the wrong architecture,
+ non-EFI loaders, etc.
+- New Btrfs driver, contributed by Samuel Liao based on GRUB 2.00 Btrfs
+ code.
