WARNING - UNSTABLE BETA VERSION
===============================
All versions 1.1x are unstable beta releases - use them only for testing,
and never distribute a program that is packed with them !
There will be hidden bugs. Really.
The current stable release is 1.04, and the next stable release
will be called version 1.20.
The main news since 1.04 are support for bootable Linux kernels ("vmlinuz/386")
and direct Linux ELF-to-memory decompression ("linux/elf386"), so there's
no reason to use the unstable versions unless you want to try the new formats.
