The BUGs were fixed:

  • multi-volume archive in one command.
  • 7-Zip 9.24 alpha - 9.30 alpha versions could not extract ZIP archives
  • encrypted with PKWARE-AES method.

Some BUGs of 7-Zip 9.31 alpha were fixed:

  • 7-Zip could not unpack some RAR archives
  • 7-Zip File Manager could work incorrectly for unpacking from solid archives, if archive was open in 7-Zip File Manager. Also 7-Zip File Manager could leave some unpacked files in TEMP folder of Windows.
  • So look your TEMP folder and remove folders that have "7z" prefix in name.
