+- Update to 4.2.0.
+  * Changes in RAR compression:
+    a) Multithreaded RAR compression is enabled by default. You can
+       disable it with -mt1 switch.
+       Comparing to RAR 4.11, some speed gain is possible in single
+       processor mode as well.
+       Speed gain depends on data type and average file size.
+       Several cores are utilized more efficiently when compressing
+       large files.
+    b) We had to increase memory requirements to achieve higher
+       compression speed. General RAR compression algorithm
+       allocates about 120 MB comparing to 40 MB in RAR 4.11.
+    c) RAR text compression algorithm cannot utilize several CPU
+       cores efficiently, so its performance in multiprocessor
+       environment is much lower than for general algorithm. Also
+       its decompression speed is much lower than in general
+       algorithm regardless of CPU number. So we decided to disable
+       the text algorithm by default.
+       If you need maximum possible compression ratio for plain
+       text data regardless of speed, you can enable the text
+       compression with -mct switch.
+  * RAR general decompression algorithm speed is slightly improved
+    though not to same extent as RAR compression. RAR
+    decompression is not able to use several processor cores, so
+    its performance does not depend on a number of cores.

-      and bearer of the worldwide exclusive usage rights to reproduce
-      and distribute RAR and WinRAR is win.rar GmbH, Schumannstr. 17,
-      10117 Berlin, Germany.
-
-   2. Anyone may use this software during a test period of 40 days.
-      Following this test period of 40 days or less, if you wish to
-      continue to use RAR, you must purchase a license.
-
-   3. There are 2 basic types of licenses issued for RAR, these are:
-
-      a.  A single computer usage license. The user purchases one license
-          to use RAR archiver on one computer.
-
-          Home users may use their single computer usage license on
-          all computers which are in property of the license owner.
-
-          Business users require one license per computer RAR is
-          installed on.
-
-      b.  A multiple usage license. The user purchases a number of usage
-          licenses for use, by the purchaser or the purchaser's employees
-          on the same number of computers.
-
-          In a network (server/client) environment you must purchase
-          a license copy for each separate client (workstation)
-          on which RAR is installed, used, or accessed. A separate
-          license copy for each client (workstation) is needed regardless
-          of whether the clients (workstations) will use RAR simultaneously
-          or at different times. If for example you wish to have
-          9 different clients (workstations) in your network with access
-          to RAR, you must purchase 9 license copies.
-
-      A user who purchased a RAR license, is granted a non-exclusive
-      right to use RAR on as many computers as defined by the licensing
-      terms above according to the number of licenses purchased,

                 RAR - What's new in the latest version
 
 
+   Version 4.20
+
+   1. Changes in RAR compression:
+
+      a) Multithreaded RAR compression is enabled by default.
+         You can disable it with -mt1 switch.
+
+         Comparing to RAR 4.11, some speed gain is possible
+         in single processor mode as well.
+
+         Speed gain depends on data type and average file size.
+         Several cores are utilized more efficiently when compressing
+         large files.
+
+      b) we had to increase memory requirements to achieve higher
+         compression speed. General RAR compression algorithm allocates
+         about 120 MB comparing to 40 MB in RAR 4.11;
+
+      c) RAR text compression algorithm cannot utilize several CPU cores
+         efficiently, so its performance in multiprocessor environment
+         is much lower than for general algorithm. Also its decompression
+         speed is much lower than in general algorithm regardless of
+         CPU number. So we decided to disable the text algorithm by default.
+
+         If you need maximum possible compression ratio for plain text data
+         regardless of speed, you can enable the text compression
+         with -mct switch.
+
+   2. RAR general decompression algorithm speed is slightly improved,
+      though not to same extent as RAR compression. RAR decompression
+      is not able to use several processor cores, so its performance
+      does not depend on a number of cores.

       modification time of archived entry to current system time.
       Previous RAR versions did not fill this field, resulting in
       meaningless modification time for stdin.
-
-   
-   Version 3.80
-
-   1. Switch -o[+|-] can now be specified when archiving to control
-      RAR behavior when updating already existing files in archive.
-      Unlike already existing -f and -u, switch -o[+|-] ignores
-      the file date and compares only file names.
-
-      Available overwrite modes are:
-
-        -o           Ask before overwrite
-                     (default for extracting files);
-
-        -o+          Overwrite all
-                     (default for updating archiving files);
-
-        -o-          Skip existing files.
-
-   2. New -dw switch enables "Wipe files" mode when deleting archived files.
-      Before deleting file data are overwritten by zero bytes to prevent 
-      recovery of deleted files.
-
-   3. RAR displays the total progress bar when unpacking a multivolume
-      archive if all volumes are present in the same folder.
-
-   
-   Version 3.71
-
-   1. Archive names in rar.log error log file always include
-      the full path.
-
-   2. Bugs fixed:
-
-      a) if -ag switch mask contained archive number, month and minute
-         characters, RAR placed 'I' character instead of minute value
-         into generated archive name for archive numbers exceeding 1;
-
-      b) RAR could crash when decompressing some of corrupt RAR archives.
-
-
-   Version 3.70
-
-   1. New switch -sc<charset>[objects] allowing to select character
-      sets for archive comments and list files. It replaces -fcu switch
-      introduced in RAR 3.60, which was removed from list of supported
-      switches. Now you need to specify -scuc instead of -fcu to use
-      Unicode comments. Unlike -fcu, -sc also supports OEM and ANSI charset.
-
-   2. Operation progress is displayed when adding the recovery record.
-
-   3. RAR displays "Calculating the control sum" message when calculating
-      CRC32 control sum for newly created RAR volume. Previous versions
-      also calculated the volume control sum, but they did it silently.
-
-   4. Stack overflow vulnerability has been corrected in password
-      processing module of console RAR and UnRAR. GUI WinRAR is not
-      affected. We are thankful to the iDEFENSE LABS for reporting this bug.
-
-
-   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.

                 RAR - What's new in the latest version
 
 
+   Version 4.20
+
+   1. Changes in RAR compression:
+
+      a) Multithreaded RAR compression is enabled by default.
+         You can disable it with -mt1 switch.
+
+         Comparing to RAR 4.11, some speed gain is possible
+         in single processor mode as well.
+
+         Speed gain depends on data type and average file size.
+         Several cores are utilized more efficiently when compressing
+         large files.
+
+      b) we had to increase memory requirements to achieve higher
+         compression speed. General RAR compression algorithm allocates
+         about 120 MB comparing to 40 MB in RAR 4.11;
+
+      c) RAR text compression algorithm cannot utilize several CPU cores
+         efficiently, so its performance in multiprocessor environment
+         is much lower than for general algorithm. Also its decompression
+         speed is much lower than in general algorithm regardless of
+         CPU number. So we decided to disable the text algorithm by default.
+
+         If you need maximum possible compression ratio for plain text data
+         regardless of speed, you can enable the text compression
+         with -mct switch.
+
+   2. RAR general decompression algorithm speed is slightly improved,
+      though not to same extent as RAR compression. RAR decompression
+      is not able to use several processor cores, so its performance
+      does not depend on a number of cores.

-   Version 3.80
-
-   1. Switch -o[+|-] can now be specified when archiving to control
-      RAR behavior when updating already existing files in archive.
-      Unlike already existing -f and -u, switch -o[+|-] ignores
-      the file date and compares only file names.
-
-      Available overwrite modes are:
-
-        -o           Ask before overwrite
-                     (default for extracting files);
-
-        -o+          Overwrite all
-                     (default for updating archiving files);
-
-        -o-          Skip existing files.
-
-   2. New -dw switch enables "Wipe files" mode when deleting archived files.
-      Before deleting file data are overwritten by zero bytes to prevent 
-      recovery of deleted files.
-
-   3. RAR displays the total progress bar when unpacking a multivolume
-      archive if all volumes are present in the same folder.
-
-   
-   Version 3.71
-
-   1. Archive names in rar.log error log file always include
-      the full path.
-
-   2. Bugs fixed:
-
-      a) if -ag switch mask contained archive number, month and minute
-         characters, RAR placed 'I' character instead of minute value
-         into generated archive name for archive numbers exceeding 1;
-
-      b) RAR could crash when decompressing some of corrupt RAR archives.
-
-
-   Version 3.70
-
-   1. New switch -sc<charset>[objects] allowing to select character
-      sets for archive comments and list files. It replaces -fcu switch
-      introduced in RAR 3.60, which was removed from list of supported
-      switches. Now you need to specify -scuc instead of -fcu to use
-      Unicode comments. Unlike -fcu, -sc also supports OEM and ANSI charset.
-
-   2. Operation progress is displayed when adding the recovery record.
-
-   3. RAR displays "Calculating the control sum" message when calculating
-      CRC32 control sum for newly created RAR volume. Previous versions
-      also calculated the volume control sum, but they did it silently.
-
-   4. Stack overflow vulnerability has been corrected in password
-      processing module of console RAR and UnRAR. GUI WinRAR is not
-      affected. We are thankful to the iDEFENSE LABS for reporting this bug.
-
-
-   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.
