      Its purpose is to apply switches like -av, -tl and -cl to archive.

   2. New command line -sl<size> and -sm<size> switches to set size
      limits of processing files.

   3. 7Z added to list of formats stored without compression
      when using -ms switch without a parameter.

      operations including extracting and deleting files. Previously
      it was supported by only archiving command.
