Configs that work with older versions of Syslinux usually work with
newer versions as well, it happens very seldom that an option gets
deprecated. You should however note, that the .c32 modules are not
compatible across versions. But this should not affect our/your/my ISO
images since all the (U)EFI boot files reside on the EFI El-Torito FAT16
image while the BIOS boot files reside directly in the ISO filesystem.
On USB thumb drives that use the most primitive boot method (one single
FAT32 partition) to boot both on UEFI and on BIOS you have to take care.
For this reason in Desinfec't and current builds of LessLinux I
partition thumb drives and give them one legacy boot partition and one
EFI boot partition. Combined with gptmbr.bin those thumb drives work
very well on both UEFI and BIOS. Currently I use Shim+GRUB (for
Desinfect) and Preloader+Gummiboot (for LessLinux), but I really look
forward to be able to switch to PreLoader+Syslinux to get back to one
config.

Mattias
