++
++2006-05-02 Vesa Jaaskelainen <chaac@nic.fi>
++
++ * stage2/shared.h (vbe_mode): Back ported aligment fix from GRUB 2

++2006-04-20 Robert Millan <robertmh@gnu.org>
++
++ Fixes for kernel of FreeBSD:

++ 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>

++
++2005-09-29 Yoshinori K. Okuji <okuji@enbug.org>

++ Increased the version number to 0.6.94.
++
++2005-09-28 Yoshinori K. Okuji <okuji@enbug.org>
