User visible changes for UPX
==================================================================
Changes in 1.12 beta (XX Jan 2001):
* UNSTABLE BETA VERSION - DO NOT USE EXCEPT FOR TESTING
* implemented several new options for finer compression control:
`--all-methods', `--all-filters' and `--brute'
* linux/386: added the option `--force-execve'
Changes in 1.11 beta (20 Dec 2000):
* UNSTABLE BETA VERSION - DO NOT USE EXCEPT FOR TESTING!!! REALLY.
* UNSTABLE BETA VERSION - DO NOT USE EXCEPT FOR TESTING
* vmlinuz/386: new format - UPX now supports bootable linux kernels
* linux/386: added the new direct-to-memory executable formats - no
more temp files are needed for decompression!
@ -188,7 +194,7 @@ Changes in 0.60 (06 Mar 1999)
* fixed a bug which could make UPX hang when an exe header contained
an illegal value
* added some compression flags for the win32/pe format
* added support for Atari ST executables (atari/tos)
* added support for Atari ST/TT executables (atari/tos)
* improved compression ratio
* improved compression speed
