Download p7zip 4.47

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 4.47 as the version number, which runs parallel with the 7-Zip program on the Windows platform. The list of customizations looks like this:

Version 4.47:

• From Windows version of 7-zip 4.47:
  • Bugs of 7-Zip 4.46 beta were fixed: BZip2 could work incorrectly
• From Windows version of 7-zip 4.46:
  • New fast compression mode for Deflate method in Zip and GZip.
  • Some bugs were fixed.
• LZMA Benchmark:
  • cygwin : RAM size detection
  • computation of the CPU %
• fixed #1721827 : install.sh now copies 7z.so
• Client7z now uses 7z.so instead of 7za.so
• new target : cygwin with asm
• LZMA SDK added in the source package (CPP/7zip/Compress/LZMA_Alone)
• fixed #1716987 : 7zr removed from 4.45 binary distribution
• fixed #1706002 : make and install.sh use the same variables in the same order.

Version 4.45:

• From Windows version of 7-zip 4.45:
  • Default dictionary size was increased: Normal: 16 MB, Max: 32 MB.

  • x86 or x86_64 : ASM version of crc32 available
• better detection of executable file (scripts do not need BCJ/BCJ2 filter)
• default permissions are now:
  • for a file : -rw——-
  • for a directory : drwx——
• on MacOSX, locale is always utf8 (because the MacOSX filesystem supports only utf8 filenames)
