Posted on Friday, November 18 2005 @ 22:27 CET by LSDsmurf

Changelog:

Files 7zFMn.exe, 7zGn.exe, 7-zipn, 7za.exe, 7zC.sfx were removed from 7-zip package
7-Zip now uses uncompressed SFX: 7z.sfx
Sfx modules 7z.sfx and 7zCon.sfx now use msvcrt.dll
Speed optimizations in LZMA maximum/ultra compressing.
LZMA now supports word size up to 273
7-Zip now reduces dictionary size for LZMA, if you compress files smaller than specified dictionary size.
7-Zip now can use large memory pages:
- GUI: 7-Zip File Manager / Options / Settings / Use large memory pages.
- Command line version: -slp switch.
  This feature allows to increase speed of compressing. But 7-Zip can make some pause at starting of compressing for allocating large pages. Also Task Manager doesn't show real memory usage of program, if 7-Zip uses large pages. This feature works only on Windows 2003 / XP x64 / Vista. Also you must have administrator's rights for your system. Recommended size of RAM: 1 GB or more. To install this feature you must run 7-Zip File Manager at least once, close it and reboot system.
Some bugs were fixed
