2004-02-19 Brett Johnson <[e-mail]>
        * Fixed bug where default image initrd would carry over to another
          image that was selected interactively (iff the newly selected image
          did not have an initrd).
        * Added support for subnet-specific config files in netfs.
2004-02-17 Brett Johnson <[e-mail]>

2003-08-19 Stephane Eranian <[e-mail]>
	* integrated ia32 updates from Matt
	  Tolentino <[e-mail]>
2003-08-13 Stephane Eranian <[e-mail]>
	* updated elilo.txt and netbooting.txt
	* fix a bug in choosers/simple.c:print_infos().
	  it needs to check if config file path is absolute
	  when printing filename.
	* move definitions of CHAR_SLASH CHAR_BACKSLASH to elilo.h
	* fix a bug in read_config() where it would try other
	  filename even when the user explicitely specified one
	  via -C, now it fails it that file cannot be opened.
	* updated simple chooser set of builtin command keys
	* command keys are only valid if first on the line
	* increase default buffer size and increment when netbooting
2003-06-04 Stephane Eranian <[e-mail]>
	* fix fs/netfs.c to work with recent version
	  of EFI (14.61 or higher) which do not have the 
	  TFTP problem anymore. fix submitted by Guy Laborde
2003-04-21 Stephane Eranian <[e-mail]>
	* ext2fs support is turned off by default to avoid
	  problems with ext3-formatted partitions.

	* clean up in glue_localfs.c w.r.t. CHAR16 in set_default_path()

	  open via netfs. Suggestion and initial patch by Guy Laborde from HP.
2003-01-28 Stephane Eranian <[e-mail]>
	* fix the set_default_path() routine in glue_localfs.c. It would not

	  to avoid conflicts with \\ as a path separator
2002-06-11 Stephane Eranian <[e-mail]>
	* fixed the return value in efi_main(). elilo was always returning
	  success even in case of failure. Bug reported by Egan Ford <[e-mail]>
	* applied patch from Richard Hirst <[e-mail]> to fix an
	  initialization bug in choosers/textmenu.c 
	* applied patch from Richard Hirst <[e-mail]> to make elilo

	  syspdeps_getopt()
	* added IA-64 command line option (-r) for relocation

	  a strXcmp() on a NULL string.

2001-08-01  Stephane Eranian <[e-mail]>
	* fixed bug in fs/netfs.c where it would not handle the small buffer 
	  error correctly. The retry path was not allocating a bigger buffer.

	  load target, i.e. a kernel image file.

	* added support for user to abort a load of a compressed file.
	* added 2 new ia-64 only config file options allowing kernel relocation: 
	  'relocatable' as a global or per image option.

	  Brent Casavant <[e-mail]>.
	* added slash/backslash conversion for filenames on vfat filesystems.

	* fixed error in netfs.c where the kernel name was not correctly set in
	  netfs_query_layer()
	* fixed to wait_timeout() to correct the problem with the interactive prompt when
	  return is hit directly when no text
	* fixed command line argument destruction problem, now we make a copy of them. This
	  was affecting elilo when called directly from bootmanager with NVRAM options.

2001-06-28  Stephane Eranian <[e-mail]>
	* removed W2U() hack to get from wide-char to unicode. Use -fshort-wchar option instead.
	* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
