RAR - What's new in the latest version   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.
