Download p7zip 4.61

The compression format 7z is increasingly used for compressing files. The program p7zip is specially written for various Unix, BSD and Linux platforms and offers full support for the 7z format. The developer has released a new version with 4.61 as the version number, which runs parallel with the 7-Zip program on the Windows platform. The list of changes since the previous entry in the Meuktracker looks like this:

Version 4.61:

• 7-Zip now supports LZMA compression for .ZIP archives.
• Ask for password twice when creating encrypted archive
• 7zG added (read GUI/readme.txt)
• p7zip didn’t use the BCJ /BCJ2 filters for executables (:
• makefile.linux_amd64_asm_icc added (tested with Intel Compiler 11 on Ubuntu 8.04 x64)
• 7-Zip now can unpack UDF, XAR and DMG/HFS archives.
• It’s allowed to use -t switch for “list” and “extract” commands.

Version 4.58:

• From Windows version of 7-zip 4.58:
  • Some speed optimizations.
  • 7-Zip now can unpack .lzma archives.
  • Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes
  • Default mode: 7-Zip uses UTF-8, if the local code page doesn’t contain required symbols.
  • -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
  • -mcl switch: 7-Zip uses local code page.
  • Now it’s possible to store file creation time in 7z and ZIP archives (-mtc switch).
  • 7-Zip now can unpack multivolume RAR archives created with “old style volume names” scheme and names *.001, *.002, …
  • Now it’s possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on

• Bug #1941574 : gzip files always marked as OS FAT, Now p7zip uses “Unix”.
• Bug #1947700 : file containing excluded files not read When using the -xr flag to list files not to be included in the archive the file is not read if it is a symbolic link.
• Feature Requests #1868080 : add support to compile for NetWare (makefile.netware_asm_gcc_3.X)
• Patch #1883893 : Incorrect path ref to docs in man pages (When using the last ($DEST_DIR) argument with install.sh)

• bug : p7zip used to build a zip file with an “FAT” header instead of “Unix” header If LANG was set, “unzip” tried to translate the filenames from “FAT” to locale …
