 675   developmental version of GRUB officially.

 684
 685
 686 New in 0.7:
 687
 688 * Problems in cross-compiling PUPA are fixed.
 689
 690 * Use -mrtd and -mregparm=3 to reduce the generated code sizes. This
 691   means that any missing prototypes could be fatal. Also, you must take
 692   care when writing assembly code. See the comments at the beginning of
 693   startup.S, for more details.
 694
 695 * New utility, ``pupa-setup''. This sets up PUPA to make it bootable
 696   from a real disk.
 697
 698 * New commands, "prefix", "insmod", "rmmod" and "lsmod" are added into
 699   the rescue mode to manipulate PUPA modules.
 700
 701 * Linux support is added. Initrd is not support yet.
 702
 703 * Reduce the size of a core image significantly by compressing a large
 704   part of the core image and decompressing itself at boot time. The
 705   currently used algorithm is LZO (more precisely, LZO1X-999). So you
 706   have to install LZO to build PUPA. See
 707   <http://www.oberhumer.com/opensource/lzo/>, for more information.

 721   Standards.
