                RAR - What's new in the latest version


   Version 3.60

   1. New 'ch' (change archive parameters) command line mode command.
      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.

   4. Switch -e[+]<attr> is now supported by most of command line
      operations including extracting and deleting files. Previously
      it was supported by only archiving command.


   Version 3.51

   1. Bugs fixed:

      a) previous version tried to create symbolic links even when
         testing an archive;

      b) symbolic links unpacked with -ow switch had a wrong owner;

      c) RAR failed to restore setuid and setgid access rights
         when unpacking files with -ow switch.


   Version 3.50

   1. New -n<mask> and -n@<listfile> switches set additional include
      filters, so only files matching the mask will be processed.

   2. New -id[c,d,p,q] switch. Additionally to previously available
      -idp switch (disable percentage indicator), switches -idc, -idd
      and -idq instruct the console RAR to hide the copyright message,
      "Done" message and all information messages.

   3. Switch -e+<attr> allows to specify file include attributes mask.

      It is possible to use 'd' and 'v' characters in -e[+]<attr> switch
      to denote directory and device attributes.

   4. Switch -ver[n] supports the optional 'n' parameter also when
      archiving. It limits the maximum number of file versions.


   Version 3.41

   1. When adding new files to already existing RAR solid archive,
      RAR 3.40 compression ratio was lower than in RAR 3.30.
      Corrected in this version.

   2. If archived Unicode name is invalid, RAR 'l' and 'v' commands
      display ASCII file name instead of corrupt Unicode.


   Version 3.40

   1. "Fastest" (-m1) RAR compression method has been modified
      to provide much higher compression speed and lower ratio.
      It may be useful for tasks requiring the high speed like
      regular backups.

      You may increase "Fastest" speed even more selecting 64KB
      compression dictionary instead of default 4MB.

   2. Starting from this version, RAR volumes contain the volume number
      field. Volume number is displayed by 'L' and 'V' commands
      in the line with the total volume information.

      This feature may be useful if original volume names are lost
      and you need to rename them to correct names.

   3. Commands 'L' and 'V' display NTFS "Compressed" attribute
      in archive listing.

   4. Switch -ag may include an optional text enclosed in '{' and '}'
      characters. This text is inserted into archive name.
      For example: -agHH{hours}MM{minutes}

   5. Removed the erroneous "CRC error" message when unpacking symlinks
      from archive created with -hp<pwd> switch. In fact, such symlinks
      were unpacked correctly.

   6. RAR displays the operation progress while repairing
      an archive containing the recovery record.


   Version 3.30

   1. Several -v<size> switches can be specified in the command
      line mode to set different sizes for different volumes.
      For example, 'rar a -v100k -v200k -v300k arcname' command
      sets 100 KB size for first volume, 200KB for second
      and 300KB for all following volumes.

   2. New -st[name] switch to compress data from stdin
      (standard input).

   3. Data analyzing module is tuned to detect executable and audio
      data more accurately. Erroneous selecting of executable
      and audio algorithms could reduce the compression ratio
      in some situations.

   4. 'vt' and 'lt' commands display symlink target names,
      when listing RAR/Unix archives contained symbolic links.
      These commands also display NTFS stream names, when listing
      WinRAR archives contained streams.


   Version 3.20

   1. Previous RAR versions stored only the file modification time
      and only in DOS FAT format with 2 seconds precision.
      While it was enough for FAT, modern file systems provide
      a higher precision. Now RAR format can preserve modification,
      creation and last access time with the precision up to 0.0000001
      second. RAR/Unix supports modification and last access time
      with 1 second precision.

      You may use the command line -ts<m,c,a> switch to choose time
      fields to process and precision of these fields.

   2. 'rn' command allows to rename files inside of RAR archives.

   3. 'lb' and 'vb' commands list contents of archive in the bare mode -
      file names without any additional information.

   4. RAR displays the operation percentage when creating recovery
      volumes or reconstructing missing or corrupt volumes.

   5. Directories are archived after files which they contain,
      so directory time and owner information is set after unpacking
      its contents. Otherwise unpacking files may modify
      the directory time.
