Version 4.20
============
- From Windows version of 7-zip 4.19 and 4.20 :
- BZip2 code was rewritten. Now it supports 3 modes: Normal, Maximum and
Ultra. In Normal mode it compresses almost as original BZip2 compressor.
Compression ratio in Maximum and Ultra modes is 1-3% better for some files,
but Maximum Mode is about 3 times slower and Ultra Mode is about 8 times
slower than Normal mode.
- Console version now prints all messages to stdout by default,
and if -so switch is specified, 7-Zip prints messages to stderr.
- Some bugs were fixed
- Updating "contrib/VirtualFileSystemForMidnightCommander/" with u7z-4.16beta.tar.bz2
- bug #1204993 (does not find broken filenames)
- bug #1201244 (Missing files in p7zip_4.18_x86_linux_bin.tar.bz2)
- makefile.linux_x86_ppc_alpha : flag "-fPIC" added
