· PXELINUX: disable a hack that would make localboot work on some machines, but break just about as many. Some machines which worked with "localboot 0" in previous versions may need "localboot -1" in this one. If you have a machine which requires "localboot -1", a copy of the dmidecode or sysdump output would be appreciated.
· Include a set of diagnostics by Gene Cumm.

· ISOLINUX: recognize the directory names /boot/syslinux and /syslinux, and the filename syslinux.cfg in addition to the isolinux-specific names. Thus, syslinux.cfg is now a generic name, whereas isolinux.cfg or extlinux.conf is specific to different derivatives.

June 29th, 2010· Major code base changes; all filesystem rewritten in C. This work was done primarily by Liu Aleaxander (Yuanhan Liu).
· EXTLINUX: btrfs and ext4 support. btrfs support was done by Alek Du of Intel.
· EXTLINUX is no longer a separate derivative; extlinux and syslinux both install the same loader (ldlinux.sys); for the Linux-based installers the extlinux binary is used for a mounted filesystem; the syslinux binary for an unmounted filesystem.
· When loading a new configuration file with the CONFIG command, one can now also specify a new current directory with an APPEND statement.
· Full ADV support for Syslinux, so boot-once and MENU SAVE works.
· Full support of GPT-partitioned disks, including disks and/or parititions larger than 2 TiB (if supported by BIOS.)

· HDT: code cleanup, small bugfixes
· The "linux" syslinux installer (syslinux-nomtools) now has a command-line syntax closer to the extlinux installer. The mtools, dos and win32 installers will get this new syntax eventually, but it is not implemented yet.
· chain.c32: support booting GPT partitions by index, GUID, label.
· chain.c32: support booting the Syslinux partition with "fs".
· chain.c32: implement gpt.txt hand-over protocol.
· chain.c32: support for chainloading Grub stage 2.
· PXELINUX: TFTP URL syntax (tftp://) supported even when not running gPXE/gpxelinux.
· New ls.c32 module to display the contents of the disk from the command line, and pwd.c32 to display the current directory.
· rosh.c32 (read only shell) updated and hopefully usable.
· PXELINUX: Support "localboot -1", just like the other derivatives.
· gfxboot.com removed in favor of gfxboot.c32.
· New MENU HELP statement to display fullscreen help text as a result of a menu selection.
· memdiskfind utility that can be used with the phram driver in the Linux kernel to mount a memdisk.
· ifcpu.c32: Adding usage when no parameters are given, adding PAE support.
· ifcpu.c32, ifcpu64.c32: handle more than one argument per target.
· isohybrid: C version which does not require Perl.
· New command MENU IMMEDIATE to permit hotkeys to activate immediately without needing Enter.
· mdiskchk.com supports a --no-sequential (or -n) option to suppress the classic all-drive-probing heuristic. Useful on BIOSes who crash/hang when certain drive numbers are probed.
· ElTorito.Sys DOS driver now scans drive numbers upwards instead of downwards, in order to avoid a fairly common bug on some BIOSes where probing drive 0xFF causes a failure.
October 6th, 2009· This release adds some minor new features, including the ability to add overrides to DHCP options in the pxelinux binary, a new version of the Hardware Detection Tool, and some fixes to the Gfxboot module.

· MBR: produce alternate MBR variants which force the drive number to hd0 (_f variants), or force the drive number to hd0 if the Ctrl key is pressed (_c variants.) Furthermore, add an MBR variant (altmbr*.bin) which ignores the active flag and instead boots the partition number specified in the byte at offset 439 decimal.
· Add IPAPPEND strings to com32 modules, especially needed for linux.c32.
· New MENU SAVE directive which saves the latest menu selection until the next boot. Currently only implemented for EXTLINUX.
