Hello all,

we are pleased to announce the second public beta release of our
new executable packer: UPX. The Ultimate Packer for eXecutables
is a portable, extensible, high-performance executable packer for
five different executable formats. It achieves an excellent compression
ratio and offers *very* fast decompression.

UPX can pack the following executable formats:
        dos/exe, dos/sys, dos/com, djgpp2/coff and watcom/le

Here are some compression results, just to show you how UPX performs:

       File size        Compressed size  Ratio    Type     Name
   -----------------   ----------------- -----  --------   --------
  1239040 ->  524884  1236992 ->  522122 42.2% djgpp2/coff cc1.exe
   341444 ->  121732   328188 ->  121429 37.0%   dos/exe   gws.exe
  1267629 ->  450513  1013327 ->  437311 43.2%  watcom/le  descent2.exe

Compare these values with:

     cc1.exe [DJP 1.07]       1239040 ->  649684
     gws.exe [APACK 0.82b]     341444 ->  121992
     gws.exe [WWPACK 3.05b5]   341444 ->  125422
descent2.exe [PMWLITE 1.33]   1267629 ->  670635

As we mentioned above this is a BETA TEST release, so DO NOT USE THIS
VERSION EXCEPT FOR TESTING. Only compress backups of your executables.

You can find UPX 0.20 at:

Please report all problems or suggestions to the authors. Thanks.

Enjoy,
Laszlo & Markus

P.S. UPX is the successor of the DJP executable packer
