  • Bugfix for the extraction progress bar for some 7z files.

New in The Unarchiver 3.3 (Sep 7, 2012)

  • Fixes for Tar and RPM files.
  • There are now two command-line utilities available, unar and lsar, which can be used to unpack and list archives, respectively. They are still in development and not really feature-complete, but they should work. These are available as precompiled binaries for both OS X and Windows on the download page, and can also be built on Linux.

  • Updated French localization by Ronald Leroux.
  • Can now join simple split files (those named .001, .002 and so on).

  • Fixes to the LZMA parser.

New in The Unarchiver 2.0 (Aug 23, 2009)

  • Support for many new formats and algorithms:
  • Partial support for SITX archives. Most archives should open fine, but SITX's special JPEG compression is unsupported. (If you are a programmer and want to help out with getting this working, I'd be happy to hear from you!) Some preprocessing filters are also nsupported.
  • Other new formats: XAR, ALZip, LZMA-utils, Compact Pro, PackIt, ARJ
  • Encrypted RAR archives.
  • WinZip-style encrypted Zip files using AES.
  • Can decompile NSIS installers to get the files inside. This seems to work for versions all the way back to 1.1o or so, but a lot of guessing is involved so it might fail on some files.
