++2006-05-02  Pavel Roskin  <proski@gnu.org>
++
++	* stage2/stage2.c (run_menu): Fix "savedefault" to save only top
++	level menu positions.  Remember current position when calling a
++	submenu.  Don't recalculate it when booting from a submenu.
++
++	* grub/main.c (main): Make sure the boot drive number doesn't
++	exceed 255.
++
++2006-05-02  Vesa Jaaskelainen  <chaac@nic.fi>
++
++	* stage2/shared.h (vbe_mode): Back ported aligment fix from GRUB 2
++	to GRUB Legacy.  Problem reported by Gerardo Richarte.
++
++2006-04-23  Robert Millan  <robertmh@gnu.org>
++
++	* grub/asmstub.c (get_diskinfo): Optimize sysctl routine.
++
++2006-04-20  Robert Millan  <robertmh@gnu.org>
++
++	Fixes for kernel of FreeBSD:
++	* grub/asmstub.c (get_diskinfo): Toggle "kern.geom.debugflags" sysctl
++	before opening a device for writing.
++	* util/grub-install.in: Devices don't have this "r" prefix anymore.
++
++2006-04-16  Yoshinori K. Okuji  <okuji@enbug.org>
++
++	* docs/multiboot.texi: Correct the offset of address
++	fields. Reported by Jeroen Dekkers.
++
++2006-03-21  Yoshinori K. Okuji  <okuji@enbug.org>
++
++	* stage2/builtins.c (setup_func): Specify the size of DEVICE to
++	grub_strncat instead of a strange number 256. Reported by Vitaly
++	Fertman <vitaly@namesys.com>.
++
++2005-09-29  Yoshinori K. Okuji  <okuji@enbug.org>
++
++	* docs/multiboot.texi: Fix a bug in the byte order of
++	boot_device. I hope this won't affect any OS image.
++	Increased the version number to 0.6.94.
++
++2005-09-28  Yoshinori K. Okuji  <okuji@enbug.org>
++
++	* stage2/boot.c (load_image): Even if an OS image is an ELF
++	object, use the a.out kludge if MULTIBOOT_AOUT_KLUDGE is
++	specified.
++
+ 2005-05-08  Yoshinori K. Okuji  <okuji@enbug.org>
