What's new in WinRAR & RAR

What's new in the latest WinRAR and RAR version

All users of the Microsoft Windows' 64-bit version are strongly recommended to install the 64-bit-version of WinRAR as integration and performance have been highly improved compared to the 32-bit-version of WinRAR.

As always, we definitely recommend updating your WinRAR software now to the latest full version (below), so that you too can make full use of, the most recent, reliable, stable and secure version of WinRAR.

WinRAR 5.50 (released August 2017):

   1. WinRAR and command line RAR now use the RAR 5.0 archive format by default.

      You can change it to the RAR 4.x compatible format with the "RAR4" option in the
      archiving dialog or with the -ma4 command line switch.

     

      If you prefer to use the RAR 4.x format as the default, in WinRAR settings use the "Create
      default..." button on the "Compression" page and set it to  "RAR4" in the displayed dialog.

  
     This change will only affect new clean installs. So if you have already saved RAR format to
      a previous version's default compression profile, WinRAR will keep that stored setting after
      installing version 5.50.

 
  2. Use the "Set master password" button in the "Organize passwords" dialog to encrypt
      saved password records and protect them from unauthorized access. Once entered, the
      master password is valid until WinRAR is closed.

     

      If saved passwords are protected with a master password, you will need to enter the master
      password and press "OK" in the password prompt to access them. Once entered, the
      master password is valid until WinRAR is closed.
      If the entered password does not match the master password, it will be treated as a normal
      password for archive operations.


      Once entered, the master password is valid only until WinRAR is closed.

      If you wish to see how protection works, enter a valid and then emptymaster password. to
      remove encryption
from previously protected password records.


      WinRAR 5.50 uses a new data format for the password organizer, so passwords stored in
      "Organize passwords" dialog are not readable by older versions. This does not
 affect
      archive encryption formats and encrypted archives are still compatible with previous

      WinRAR versions. Organizer data is converted to the new format only when you save it
      and not
 immediately after installing WinRAR 5.50.


   3. The prompt proposing to set the master password is displayed when storing a password
      in compression profile. You can enter the master password to encrypt your password data
      stored in the Windows Registry and so protect it from unauthorized access. Then you will
      need to enter the master password in the password prompt dialog to access the
      compression profile after that.


      Once entered, the master password is valid until WinRAR is closed. Close WinRAR and
      open it again after specifying the master password if you wish to see how protection
      works. 


   4. By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives.

      While AES-256 is significantly more secure than ZIP 2.0 legacy encryption algorithm, it
      can be incompatible with some older unzip software. If compatibility with such tools is
      required, you can enable the "ZIP legacy encryption" option in the password dialog or
      use the -mezl switch in the command line mode.

  

   5. Added extraction support for .LZ archives when created by Lzip compressor.

  

   6. Modern TAR tools can store high precision file times, lengthy file names and large file
      sizes in special PAX extended headers inside of eachTAR archive. WinRAR now
      supports such PAX headers and uses them when extracting TAR archives.


   7. A new "Store modification time" option on the archiving dialog "Time" page can be
      used to prohibit storing the file modification time in RAR 5.x archives. The former "High
      precision modification time" option is then replaced by the "High precision time format".


   8. New "Full paths in title bar" option in the "Settings/General" dialog.

      If enabled, the full path of the currently opened folder or archive is displayed in the
      WinRAR title bar
.

   9. New "File types to open as archives first" option in "Settings/Compression". Here you
      can define how Enter or double click on a file with non-archive extension and archive
      contents should be processed in a WinRAR file list in file management mode.
      Examples of such files are .docx or self-extracting .exe archives. You can instruct
      WinRAR either to open such files as archives first or to execute or open them with
      associated programs.


      Default settings are: to open self-extracting exe and to run other types of archives with
      non-archive extensions.


      Regardless of these options, you can always open any such archive file by pressing
      Ctrl+PgDn on its name in the WinRAR file list.


      Default folders for archives and extracted files are now moved from "Settings/
      Compression" to "Settings/Paths".


  10. The new "Copy full names to clipboard" command in "File" menu places full names of
      any selected files to your clipboard.     


  11. Changes in the context menu displayed when right clicking the file list in WinRAR:


      a) several commands, which are also present on the toolbar or the main menu, such as
        "View" and "Repair", have been removed from this context menu;


      b) "Copy full names to clipboard" command is added;


      c) "Run" for executables, "Open in associated application" for associated files, and
        "Show archive contents" for archives are added. They allow you to choose a way to
        process SFX archives and archive files with non-archive extensions.


        These items are present only in the file management mode and are not available
        inside of archives.


  12. LZ and ZIPX are added to list of associations in the Settings/Integration dialog.


  13. LZ and ZIPX extensions are added to the default list of formats for the -ms switch
       ("Specify file types to store") invoked without parameters.


  14. You can specify 'f' charset value in -sc switch to use UTF-8 encoding. For example, to
       read the contents of filelist.txt as UTF-8 text:

 
       rar a -scfl arcname @filelist.txt

  

  15. RAR "lt" and "vt" commands now display file times with nanosecond  precision.
      This precision is used in RAR5 archives created by RAR/Unix 5.50 and newer.
      Archives created by WinRAR have 100ns file time precision.


  16. Only '+', '-' and '1' precision modifiers are now supported in -ts switch. Use '+' to store the
      file time with maximum precision, '-' to omit the file time and '1' to store it with 1 second
      precision. Intermediate precision modes previously defined with '2' and '3' modifiers are
      not available in RAR 5.0 archive format and are ignored by the -ts switch.


  17. If a wrong password is entered when unpacking an encrypted file in RAR5 archive,
      WinRAR allows you to enter a valid password for that file instead of aborting the extraction.

  

  18. File path information is displayed if your mouse pointer is placed over an archiving
      filename in the operation progress window.


  19. The name of a currently active compression profile is displayed in the archiving dialog
      above "Profiles..." button.


  20. If the "Find" command is invoked from inside an archive subfolder, "File names to find"
      will include the path to this subfolder.

      So "Find" will only start searching from this subfolder.


  21. Bugs fixed:

  

      a) fixed crashes and security vulnerability when unpacking corrupt RAR archives;


      b) WinRAR failed to unpack files in ZIP archives compressed with XZ algorithm and
        encrypted with AES;

     

      c) if "Windows progress bars" option in WinRAR settings was turned off and "Put each
        file to separate archive" archiving mode was used, the "gold" part of the total progress
        bar did not display the compressed data ratio correctly;


      d) SFX archive extraction progress was incorrect when a multivolume SFX archive with
        total volume size exceeded 4 GB;


      e) if an archived folder name included trailing spaces, a user selected and extracted
        some folders in a non-root archive folder and if the "Allow potentially incompatible
        names" extraction option was turned off, WinRAR could lose one or more leading
        characters in an extracted folder name;


      f) if only creation time or last access file time was stored in a RAR5 archive with 1
       second precision, such as with the  -ma5 -tsm- -tsa1 switches, this stored time was
       ignored when extracting.




WinRAR 5.40 (released August 2016):

1.  The "Name encoding" submenu in "Options" menu selects the type of encoding for archived
     file names.
     This selection affects archive browsing and extraction commands. You can use the Ctrl+E
     keyboard shortcut to access this menu quickly.
     It can be useful when unpacking an archive without Unicode file names.
     For example, unpacking a zip file with Chinese archived names in Windows when Russian
     is specified as a language for non-Unicode programs.

2.  If RAR recovery volumes (.rev files) are present in the same folder as ordinary RAR volumes,
     the archive test command verifies the .rev contents after completing testing the .rar files.
     If you wish to test only .rev files without checking .rar volumes, you can select .rev files in
     WinRAR file list and apply "Test" only to them or in the command line run:
     rar t arcname.part1.rev

3.  While the NTFS file system permits file names with trailing spaces and dots, a lot of
     Windows programs fail to process such names correctly. If the "Allow potentially
     incompatible names" option in the "Advanced" page of the extraction dialog is turned off,
     WinRAR removes trailing spaces and dots, if any, from file names when extracting.
     This option is turned off by default.
     Command line RAR also removes trailing spaces and dots when extracting unless the -oni
     switch is specified.
  
4.  Previously the "Synchronize archive contents" update mode (the -as command line switch)
     aborted if some of the archiving folders could not be read. Now WinRAR continues
     performing the operation and preserves any archived files matching unreadable folders.

5.  The WinRAR Shift+Del delete command can now be used to delete folders containing non-
      standard file names with trailing spaces and dots.
      The usual delete to Recycle Bin with Shift+Del in previous WinRAR versions cannot delete
      such folders.
      Unlike the Del command, Shift+Del removes files permanently, they are not moved to the
      Recycle Bin. No additional prompts are issued for files with read-only and system
      attributes.

6.  You can drag folders from the  folder tree panel and drop them into other programs or the
     Desktop to copy or unpack them. Drag the archive icon in tree panel root to unpack the
     entire archive.

7.  The "New folder" button in the extraction dialog proposes a new folder name based on
     archive name instead of generic "New Folder".

8.  Command line RAR version information:

      a) when -iver switch is specified, RAR displays the version number and quits.
          You can run just "RAR -iver";

      b) "x86" or "x64" is displayed in the Windows RAR version information both for -iver and
      in the copyright title for other commands.

9.  If the -p switch is used without the optional parameter, a password can be also be set with
     file redirection or pipe.
    For example: rar -p myarc.rar myfiles < psw.txt

10. Command line RAR treats 'arcname.partN' as 'arcname.partN.rar' if 'arcname.partN' does
      not exist and 'arcname.part#.rar' exists.
      For example, to start an extraction from arcname.part01.rar run:
      RAR x arcname.part01

11. Improvements in 7z archives support:
  
      a) "Solid" status is correctly detected and reported for 7z archives with the WinRAR "Info"
           command;

      b) dictionary size is displayed for LZMA and LZMA2 7z archives in the WinRAR "Info"
          command;

      c) any unknown packed size for files inside of 7z solid block shows as '?' instead of '0'
          when browsing the archive contents in WinRAR.
  
12. The maximum comment length for RAR archives is increased from 64 to 256 KB.
       Since SFX script commands are stored in the archive comment, this allows for longer
       main and license text in SFX archives.

13. Size of the default WinRAR viewer font is scaled up properly in Windows high DPI mode.

14. Switch -scul can now be used to process big endian UTF-16 list files as well, provided that
      they have the correct byte order mark. Previously it allowed only little endian file lists.

15. The minimum supported Windows version is now Windows XP SP3. WinRAR will not run
      in Windows XP without service packs.

16. The "Settings/File list/Allow all uppercase names" option has been removed.
      This option was intended to simplify transition from MS DOS to Windows and is no longer
      needed.

17. Bugs fixed:

      a) WinRAR 5.31 x64 "Compress and email" command did not work with Microsoft Outlook
          x64;

      b) if WinRAR 5.31 version for one of right to left languages was installed in Windows with
          English or other not right to left system language, WinRAR could change Windows
          Explorer layout to right to left;

      c) if an archive was stored in a folder without "Write" permission and if the archive contents
          was extracted with drag and drop to a writable folder, WinRAR issued an unnecessary
          privileges elevation prompt.




WinRAR 5.31
 

1.  Following issues are corrected in Windows high DPI mode:

     a) if the text size in Windows settings was set to 150% or larger, the font size in WinRAR
         help was not increased accordingly, resulting in too small text;

     b) default columns width in a WinRAR file list was less than expected for 125% or larger
         Windows text setting.

2 . Interface improvements for right to left languages:

     a) proper text alignment in simple WinRAR prompts, such as confirmations to delete
         archived files or to clear the log file;

     b) "OK", "Cancel" and "Help" buttons in multi-page dialogs, such as archiving and
         extraction options or WinRAR settings, are now aligned correctly and translated to
         default Windows display language.

3.  Bugs fixed:

     a) The WinRAR SFX module could load DLL libraries from its own executable folder as a
         result of calling some Windows API functions.
         This could lead to security threat if DLL files with malicious code were stored in the same
         folder as SFX archive. Now the SFX module takes additional steps to prevent such a
         situation from Windows Vista onwards.
         Be aware that users without the latest Windows security patches installed as well as
         Windows XP users still can be affected, so they must be especially careful to run an SFX
         archive from a folder without any suspicious DLL files;
    
    b) WinRAR 5.30 failed to run .lnk files from the file list.



WinRAR 5.30 (released November 2015):

  1. Added extraction of multipart ZIP archives created by 7-Zip. Such archives have .zip.001, .zip.002, ... file extensions. You need to open .zip.001 file in WinRAR shell to browse or unpack such archive. All parts must be stored in the same folder before starting extraction. 
     

  1. Added extraction of files split to multiple parts with .001, .002, ..., extensions. You can open .001 file as a usual archive and then unpack its contents. WinRAR will combine all parts and save them to extracted file. All parts must be stored in the same folder before starting extraction. 
     
    "001" item is included to "Associate WinRAR with" list in "Settings/Integration" dialog. 
     

  1. WinRAR file list allows to use mouse Back and Forward buttons or Alt+Left and Alt+Right keyboard shortcuts to navigate in recently visited folders. 
     

  1. Folder wildcards are allowed in RAR command line in file names to archive. For example: 
     
    rar a backup c:\backup\2015*\* 
     
    will archive all "2015*" folders in c:\backup. Use -r switch to search for "2015*" also in c:\backup subfolders. 
     

  1. "Extract" button in SFX archive is changed to "Pause" when extraction is started, so it is possible to pause SFX extraction and resume it later. 
     

  1. "Skip encrypted" option in "Find files" dialog to silently skip encrypted archives while performing search command. 
     

  2. Archive test command works for tar.gz, tar.bz2 and tar.xz archives. Since TAR format does not provide file data checksums, WinRAR checks only validity of GZIP, BZIP2 or XZ container. 
     

  3. Adding a new string to WinRAR diagnostic messages window could be slow and affect the operation performance in case of thousands of errors. Now it works fast regardless of errors number. 
     

  1. New "R" object for -sc switch defines encoding of console RAR messages sent to redirected files and pipes. For example: 
     
    rar lb -scur data > list.txt 
     
    will produce Unicode list.txt with archived file names. 
     

  1. Sleep time parameter in -ri[:] switch is adjusted to lower its impact to RAR performance and especially to recovery record related operations. Higher sleep time values are needed to reduce the system load to same level as in previous versions. 
     

  1. Console RAR "l" and "v" commands display file time in YYYY-MM-DD format. 
     

  1. When extracting RAR and ZIP archives created in Unix, WinRAR maps decomposed Unicode characters to precomposed. Such conversion is required for some Unix and OS X archives to correctly unpack non-English archived names in Windows. It works for Windows versions starting from Windows Vista. 
     

  1. Modification time is set for all folders created when unpacking .7z archives. Previous versions set it only for non-empty folders. 
     

  1. WinRAR prevents a computer to go to sleep by inactivity timeout until current operation, such as archiving, extraction or another archive processing, is done. 
     

  1. Total progress bar is displayed when extracting .arj, .lzh and .cab archives (except multivolume archives). 
     

  1. Progress bar is displayed when deleting files after archiving and when clearing "Archive" attribute of archived files. 
     

  1. "Test" command also verifies contents of NTFS alternate data streams in RAR 3.x - 5.x archives. Previously their contents was checked only during extraction command. 
     

  1. SFX module sets sfxstime environment variable, which contains the module start time in "YYYY-MM-DD-HH-MM-SS-ms" format. You can specify it in Path command if you need to generate a time based unique installation path, such as "Path=myapp-%sfxstime%". 
     

  1. Bugs fixed: 
     

    1. console RAR crashed instead of displaying an overwrite prompt when attempting to add files to already existing volumes; 
       

    1. console RAR "lt" command did not display seconds in file timestamp; 
       

    1. WinRAR failed to decompress .xxe files if they did not include "section N of xxencode" string in the body; 
       

    1. WinRAR could not restore contents of NTFS alternate data stream saved with -os switch if it was split between different volumes.




    Highlights of the WinRAR 5.21 release:

    1. "Drag and drop context menu" options in "Settings/Integration/Context menu items" dialog. These allow you to disable WinRAR archiving and extraction commands in the context menu displayed after dragging and dropping files with the right mouse button.

    2. If the winrar.ini file is present in the same folder as the WinRAR installer, winrar.ini will be copied to the WinRAR program folder after installation completion.

    3. While previous versions could sometimes produce RAR5 volumes slightly smaller than the requested size, this is less likely now. In most cases volume size will now be equal to the size you specify.

    4. By default WinRAR now skips symbolic links with absolute paths in the link target when extracting. You can enable the creation of such links with the "Allow absolute paths in symbolic links" option on the "Advanced" page of the extraction dialog or with the -ola command line switch.
        Such links pointing to folders outside of the extraction destination folder can present a security risk. So it is best practice to only enable their extraction if you are sure that the archive contents are safe, such as with your own compressed backup files.

    5. Bugs fixed:

      a) WinRAR 5.20 issued unnecessary user account control (UAC) prompts when running an executable from an archive stored in a UAC protected folder. This UAC prompt is not needed when nothing is extracted to the folder archive;

  b) When unpacking RAR and ZIP archive formats WinRAR could overwrite files with read-only attribute. These archive formats are now treated the same as with WinRAR;

  c) "Elapsed time" and "Time left" were displayed incorrectly when applying the "Convert" command to multiple archives when the "Add recovery record" option was enabled.



Highlights of the WinRAR 5.20 release:

The first completely new feature means that instead of using Windows Registry to store your WinRAR settings it now uses the WinRAR.ini file instead. This is extremely useful when you want to install WinRAR on USB removable media, such as a flash drive, enabling you to run WinRAR on different computers. For more details check out the WinRAR help section under; "Configuration settings", " WinRAR.ini file". 


The second new feature, the "Open with WinRAR" command is now available within Windows context menus for all archive formats supported by WinRAR. If you do not require it, this feature can be turned off with the "Open with WinRAR (for usual archives)" option in the WinRAR "Settings, Integration, Context menu items..." dialogue. 

WinRAR 5.20 also now allows you to; use your right mouse button to drag files within File Managers, to drop them into a folder, and to select WinRAR archiving commands from inside the context menu, and also to create an archive with these files within the destination folders. This feature will allow you to easily compress 
and to secure files, saving your time when working with a lot of files in different locations.

As with all WinRAR updates, version 5.20 also provides further improvements for increased usability and compatibility: it is now better integrated with Windows User Account Control (UAC), and to ensure enhanced compatibility with other archiving formats, extraction support for ZIP and ZIPX archives using the XZ compression algorithm has also been added. 

The full list of improvements, and bug-fixes can be found below.


Improvements and bug fixes for WinRAR 5.20 are:

 1. If Windows User Account Control prevents extracting or archiving commands from creating files in system protected folders, WinRAR now attempts to start a second copy with administrator privileges to complete that operation. So it is necessary to confirm the privileges elevation in response to the User Account Control prompt, to allow this second WinRAR copy to run.

 2.  You can now drag files in Explorer with the right mouse button, drop them into a folder and to select the WinRAR archiving commands in the context menu to create an archive with these files in the destination folder.

 3. It is now possible to use the WinRAR.ini file instead of Windows Registry to store WinRAR settings. You may prefer such an approach if you plan to install WinRAR on removable media, such as a USB flash drive, so that it can be used to run WinRAR on other computers without having to set up your favorite settings.
See the  "WinRAR.ini file" topic in the "Configuration settings" chapter of WinRAR Help for details.
 
 4. Added extraction support for ZIP and ZIPX archives using their XZ compression algorithm.
 
 5. If ZIP or ZIPX archives contain any compression algorithms apart from the usual "Store" or "Deflate", algorithm names are displayed in the "Version to extract" field of the archive information dialog.
Algorithms with names unknown to WinRAR will be assigned an "m" name, where "num" is a compression algorithm numeric identifier.
 
 6. The "Open with WinRAR" command is now available in Windows context menus for archive formats supported by WinRAR. It can be turned off with "Open with WinRAR (for usual archives)" option in the WinRAR "Settings, Integration, Context menu items..." dialog.
 
 7. Command line RAR can read the default set of switches from the rar.ini file stored in your RAR program folder. Previously it was only possible to define the same set of switches for all RAR commands with the  "switches=" string. Now rar.ini also allows you to specify separate switch sets for individual RAR commands using the following syntax:
      
     
 For example:
 switches_a=-m5 -s
 switches_x=-o+
 
 8. Command "ch" also supports switches -tl, -cu, -cl for ZIP archives. Previously "ch" only allowed these switches for the RAR archive format.

 9. For archive formats lacking file time information, such as .bz2, .xz and .Z, WinRAR now sets the container archive modification time to the extracted files. This does not apply to tar.bz2, tar.xz and tar.Z, which use the file time stored in the tar headers.
   
10. The "Keep broken files" extraction option is now supported for bzip2 archives.
 
11. The WinRAR icon in each Windows context menu is now scaled up correctly in high DPI screen modes such as 150 or 200 times normal text size.

12. It is now possible to disable the WinRAR "Benchmark" command with the  "Benchmark" variable in the HKEY_CURRENT_USER\Software\WinRAR\Policy Registry key. In a multi-user environment the "Benchmark" command might corrupt shared computational resources. See the  "Registry variables" topic in the "Configuration settings" chapter of WinRAR Help for more details.

13. In addition to the "sfxcmd" variable containing the entire command line, the SFX modulenow sets the "sfxpar" variable which contains just the command line parameters, without the leading SFX module name. These variables are set before starting a program as specified in the "Setup" command.

14. The file overwrite prompt in console RAR now displays the size and modification time for existing and new files.

15. When archiving from stdin with -si switch, RAR sets the current system time to the  modification time of archived files. Previous versions did not set this time at all.

16. It is now possible to use the  -si and -v switches together. Previous versions did not allow creation of volumes when archiving from stdin.

17. A warning is issued before starting to unpack 4 GB or larger files from a RAR or ZIP archive to a FAT32 partition, so that the user can cancel the operation as FAT32 does not support files of such size.
Also this warning is issued when starting to create a RAR archive with the "Store" (-m0) method if the estimated archive size is 4 GB or more.

18. the "Select all" button in the "Settings, Integration" dialog has been renamed to "Toggle all". It now deselects archive formats if all they have already been selected.

19. The "Delete archive" extraction option now correctly removes all .zip and .7z volumes. Previously it removed only the first volume in each set for these archive formats.

WinRAR 5.11 (released 2 September 2014)

WinRAR New Zealand in association with RARLAB.com and win.rar GmbH are very pleased to present to you our latest update, WinRAR 5.11, the world's leading compression and archive management software. 

We now offer a completely new option, WinRAR can now decompress TAR archives that contain folders with pax extended headers. 

WinRAR now supports the "Keep broken files" extraction option for 7-zip archives to maintain compatibility with the other formats. 

"By providing regular updates we are taking care to achieve high compatibility, up-to-datedness, stability and reliability of our software. With the latest version we have further improved the usability of alternative archiving formats to fulfill customers' wishes plus we have fixed several recent bugs", says Öncül Kaya, Managing Director of win.rar GmbH.

Since its first public release 20 years ago WinRAR has continuously maintained their advanced track-record for high compression rates and stability, alongside all the advantages associated with the RAR format: solid archiving, split archiving, recovery records to allow reconstructing damaged files, various conversion functionalities and its many security options. 

With the latest RAR algorithm, RAR5 encryption is now far more  powerful as it includes 256-bit AES encryption - further ensuring that user data is fully protected. Your data is always safe and sound with RAR. 


Improvements and bug fixes for WinRAR 5.11 are:

   1. WinRAR now unpacks TAR archives containing folders with pax extended headers. Previous versions did
       not have that ability.

   2. "Keep broken files" extraction option is supported for 7-Zip archives.

   3. Bugs fixed:

      a) WinRAR 5.10 did not set the "hidden", "read-only" and "system" file attributes when unpacking ZIP
          archives;

      b) WinRAR 5.10 failed to update self-extracting RAR archives containing nested ZIP archives stored
           without compression;

      c) ZIP archives created with the "Do not store paths" option included unnecessary empty name records
          for folders;

      d) archived files could have a 1 hour time difference error in Windows XP;

      e) deleting a file in a RAR5 solid archive containing files stored with the -ver switch caused such files to
          lose version information;

      f) black rectangles were displayed instead of toolbar buttons in 16- and 24- bit screen color modes and
         Windows custom text sizes larger than 100.


RAR for Android 5.10 build 24 update as of August 3, 2014 now includes: 


Lower memory requirements for .7z decompression. So it is now possible to unpack .7z archives larger than available random access memory.

RAR now prevents Android from sleeping while the archiving or extracting command is working and the RAR window is visible.

Since its initial launch in February 2014 been well over 5 million installs of RAR for Android 4.0!

You can find more information here.

WinRAR 5.10 (released 13 June 2014)

   1. Added extraction support for ZIP and ZIPX archives using BZIP2, LZMA and PPMd
       compression.

   2. Added extraction support for 7z split archives (.7z.001, .7z.002, ...).

   3. Added support for AES-NI CPU instructions allowing to improve RAR encryption and
       decryption performance.

   4. Default theme images are scaled up with better quality in high DPI display mode.

   5. Environment variables, such as %temp%, can be used in "Files to add" field of archiving
       dialog.

   6. Switch -ai can be used when creating RAR archive, so predefined values, typical for file and
       folder, are stored instead of actual attributes. Previously this switch could be used only
       when extracting.



WinRAR 5.01 (released December 2013)

  1. RAR 5.0 archives can include optional quick open information, this is
      controlled with the -qo[-|+] switch or the "Quick open information" options
      group in the archiving dialog. This opens the archive contents faster in
      WinRAR.
 
      This version provides better update performance for archives containing
      both quick open information and service records, such as NTFS file security.
      The default parameters for quick open information are optimized to achieve 
      a faster open time for such archives.
 
   2. Bugs fixed:
 
      a) "Find" command could fail when searching a text string in .7z archives;
 
      b) when opening a RAR 5.0 archive with encrypted file names stored in
         another such archive, WinRAR could issue an erroneous message that
         the password is incorrect. It happened only if passwords to the inner
         and outer archives were different. It did not affect extraction, all files
         could be unpacked regardless of this message;
 
      c) the option "Use for all archives" in a password dialog did not suppress
         additional password requests for RAR 5.0 archives with encrypted
         file names;
 
      d) the WinRAR address bar did not correctly process environment variable
         based paths, such as ";"
 
      e) storing NTFS file security and alternate data streams did not work for
         file pathnames longer than 260 characters;
 
      f) the "Test" command could erroneously report damaged data in a valid
         recovery record if only some of the files in a RAR 5.0 archive were
         tested. It did not happen if the entire archive contents was tested;
 
      g) "Test" command erroneously reported errors when verifying RAR 4.x 
          Unix symbolic links;
 
      h) WinRAR "View" command did not work for files inside of BZIP2 archives;
 
      i) if the "High precision modification time" option in an archiving dialog was
         turned off, WinRAR did not store the modification time at all instead of
         storing a lower precision time;
 
      j) destination paths containing .\ or ..\ components did not work when extracting
         non-RAR archives in the WinRAR command line mode;
 
      k) WinRAR failed to unpack multivolume CAB archives.




WinRAR 5.00 (released September 2013)

   1. A totally new RAR 5.0 archiving format. You can use the "RAR 5.0" 
      option from the archiving dialog or with the -ma command line switch to
      create RAR 5.0 archives.
      
      Older software including older WinRAR versions are not able to
      decompress RAR 5.0 archives. If you plan to send an archive to
      other people, you may need to take the compatibility issue into
      consideration. You can select the "RAR" instead of "RAR5" option
      in the archiving dialog to create RAR 4.x archives that are compatible 
      with previous WinRAR versions.
   
  2. Changes in the RAR 5.0 compression algorithm:

      a) maximum compression dictionary size is increased up to 1 GB
         in 64 bit WinRAR. 32 bit WinRAR version can use up to 256 MB
         dictionary when creating an archive. Both 32 bit and 64 bit
         versions can unpack archives with any dictionary size,
         including 1 GB.

      b) default dictionary size for RAR 5.0 is 32 MB, typically resulting
         in a higher compression ratio and lower speed than with RAR 4.x's
         4 MB dictionary.
         You can use the "Dictionary size" archiving dialog option or the
         -md switch in command mode to change this value.

      c) -md switch syntax is modified to support larger dictionary
         sizes. Append 'k', 'm' and 'g' modifiers to specify the size
         in kilo-, mega- and gigabytes, ie. -md64m for 64 MB dictionary.
         If modifiers are not present, megabytes are assumed, so -md64m 
         is equal to -md64.

      d) RAR 5.0 format includes Intel IA-32 executable and delta
         compression algorithms, but RAR 4.x text, audio, true color and
         Itanium algorithms are not supported. These excluded algorithms are
         not efficient for modern data types and hardware onfigurations.

      e) RAR 5.0 decompression can utilize several CPU cores. Though not to
         the same extent as in the compression algorithm, it improves the
         decompression speed on large files with poorly compressible data or
         when using BLAKE2 checksums.

   3. Changes in RAR 5.0 archive format:

      a) file times are stored as Coordinated Universal Time (UTC) instead
         of the former local time, making file exchange among different
         time zones more straightforward.

      b) file names and archive comments use UTF-8 encoding.
   
   4. RAR 5.0 recovery record is based on Reed-Solomon error correction
      codes. If the recovery record size is large enough (5 or more), the 
      new error correction scheme provides much higher resistance to 
      multiple damage ares compared to thr RAR 4.x recovery record.
      With smaller record sizes, such as 2 or less random damage would
      result in less difference between 4.x and 5.0. For single continuous
      damage 4.x and 5.0 efficiency is about the same.

      In additional to the usual data erasures, the new recovery record
      is able to detect deletions and insertions of much larger sizees
      than in previous RAR versions. Maximum insertion size is several
      megabytes. Maximum deletion size depends on the damage type
      and in some cases can be as large as the recovery record size.
      
      Still, the best recovery performance and efficiency is achieved
      if no deletions and insertions are present, so all data including
      damaged sectors preserve their original positions. Thus, if you use
      some special software to copy an archive from damaged media,
      it is better to choose the mode, where damaged sectors are filled by
      zeroes or other data instead of cutting them out completely from the
      resulting file.

      The RAR 5.0 recovery record is more resistant to recovery record       
      damage and can utilize partially corrupt recovery record data.
      Note, though, that the "Repair" command does not fix broken blocks
      in the recovery record. Only file data are corrected. After successful
      archive repair, you may need to create a new recovery record
      for saved files.

      The new recovery record is no longer based on 512 byte sectors, it 
      incorporates more complicated data structures. So it is impossible
      to specify its size in sectors. For RAR 5.0 archives the parameter of
      the -rr[N] switch and rr[N] command is always treated as a percent of
      archive size regardless of the presence of the 'p' or '%' modifier
      character. Typically the N recovery record can repair up to N of
      continuously damaged data and increases the archive size by only
      slightly more than N. The ability to fix multiple damages is      
      proportional to N.

      We used the "Screaming Fast Galois Field Arithmetic Using Intel SIMD
      Instructions" paper by James S. Plank, Kevin M. Greenan and Ethan L. 
      Miller to improve the  Reed-Solomon coding performance.
      Also we are grateful to Artem Drobanov and Bulat Ziganshin for samples
      and ideas that allowed us to make Reed-Solomon coding more efficient.

   5. "Test" command verifies the validity of the RAR 5.0 recovery record.
      The recovery record is tested after processing all archived files.

      If a corrupt archive contains the recovery record, it might be 
      possible to repair it even if the recovery record validity test failed.
      The "Repair" command attempts to utilize even a partially damaged
      recovery record. So do treat the negative recovery record test result
      as a reason to re-create the archive if the original files are still
      available, but not as a reason to avoid "Repair" the command.

   6. Changes in RAR 5.0 encryption algorithm:

      a) encryption algorithm is changed from AES-128 to AES-256 in CBC mode.
         Key derivation function is based on PBKDF2 using HMAC-SHA256.

      b) special password verification value allows the detection of most
         wrong passwords without the necessity to unpack the entire file.

      c) if archive headers are not encrypted ("Encrypt file names" option
         is off), file checksums for encrypted RAR 5.0 files are modified
         using a special password dependent algorithm, to make it impossible
         to guess the file contents based on checksums. Do not expect such
         encrypted file checksums to match usual CRC32 and BLAKE2 values.  

   7. RAR 5.0 archives allow the utilization of 256 bit length BLAKE2sp hash
       ( https://blake2.net ) instead of 32 bit CRC32 as a file checksum.
      To do this enable the "Use BLAKE2 file checksum" option in the       
      "Options" page of the archiving dialog or specify the -htb command line
      switch to use BLAKE2 checksums.

      While producing slightly larger archives, BLAKE2 can be used for file
      contents identification. If two files have the same BLAKE2 value, it 
      practically guarantees that the file contents are the same.
      BLAKE2 error detection is also stronger than in the much shorter
      CRC32.

   8. Features removed:

      a) authenticity verification feature did not provide the required
         level of reliability and was removed.
      
      b) switch -en (do not add "end of archive" block) is not supported
         by RAR 5.0 archives, which always have an end of archive block.
         This block helps WinRAR to safely skip external data like digital
         signatures appended to archive.

      c) old style extension based arcname.rNN volume names are not
         supported by RAR 5.0 archives, which use only arcname.partN.rar
         volume names.
      
      d) file comments are not supported anymore both in RAR 4.x and RAR 5.0
         archives. The console RAR 'cf' command is removed.
         It does not affect the archive comment support, which is present
         in both versions of archive format and is not planned for removal.

   9. "Set password" command and "Dictionary size" option are moved to the
      "General" page of the archiving dialog.
   
  10. You can use the "Save symbolic links as links" option on the "Advanced" 
      page of the archiving dialog to save and restore NTFS symbolic links
      and reparse points as links, so their contents are not archived.
      The command line equivalent of this option is the -ol switch.

      The similar option for NTFS hard links is "Save hard links as links".
      Its command line equivalent is -oh switch.

      Both options are available only for the RAR 5.0 archive format.
   
  11. Added extraction is only supported for the XZ archive format.
   
  12. Changes in recovery volume processing in RAR 5.0 archive format:

      a) maximum number of RAR+REV volumes in RAR 5.0 format is 65535
         instead of 255.

      b) recovery volume operations are faster than in RAR 4.x.

      c) in addition to recovery data, RAR 5.0 REV files also store
         service information such as the checksums of protected RAR files.
         So they are slightly larger than the RAR volumes which they protect.
         If you plan to copy individual RAR and REV files to some removable
         media, you need to take this into account and specify the RAR volume
         size a few kilobytes smaller than the media size.
  
  13. Maximum path length for files in RAR and ZIP archives is increased
      up to 2048 characters.
  
  14. The command line RAR returns the exit code 11 if it detects that the
      user entered a wrong password. This code can be returned only for RAR 
      5.0 archives. It is impossible to distinguish a wrong password and data
      damage for RAR 4.x archives.

  15. 'v' and 'l' commands display archived file names in the end of the 
      line, not in that beginning as before. Also some fields previously
      available in 'l' and 'v' output are now shown only by 'lt' and 'vt'.
      
      'vt' and 'lt' commands provide the detailed multiline information
      for every archived file.

      'vta' and 'lta' also include service headers into list.

   16. Now the default charset for filelists in commands like 'rar a arcname 
       @filelist' is ANSI for both WinRAR and console RAR.
       In previous versions it was ANSI for WinRAR and OEM for console RAR.
       You can use -scl switch to override this default.

   17. Internal WinRAR viewer can now detect and display files in UTF-8
       and UTF-16 little endian encodings.

   18. UTF-16 little endian encoding is used in the RAR and WinRAR log file
       rar.log, so Unicode file names are stored in the log correctly.
       WinRAR automatically truncates the old rar.log file in non-Unicode
       format to avoid mixing different encoding in the same log file.
       For console RAR you need to delete the old rar.log manually, otherwise
       RAR will append UTF-16 messages to the existing rar.log.

       You can use the -scg switch to change the default log file encoding,
       such as -scag for ANSI encoding.

   19. Command line 'r' (repair) command can include an optional destpath\
       parameter defining the destination folder for the repaired archive:
       rar r archive.rar destpath\



   Version 4.20  (June 2012)
   1. Changes in RAR compression:
      a) The RAR general compression algorithm is now optimized for better
         utilization with multiple processor cores. While some speed gain
         is possible in single processor mode, best results will be
         achieved in a multi-core environment.
         Speed gain depends on data type and average file size.
         When compressing large files, several cores are now utilized more 
         efficiently.
      b) to acheive higher compression rates we have had to increase memory
         requirements. The RAR compression algorithm now allocates
         about 120 MB compared to 40 MB in WinRAR 4.11;
      c) the RAR text compression algorithm cannot utilize several CPU cores
         efficiently, so its performance in multiprocessor environments
         is much lower than for the general algorithm. Also its decompression
         speed is much lower than the general algorithm regardless of the
         number of CPU's. So we decided to disable the text algorithm by default.
         If you need the maximum possible compression ratio for plain text data
         regardless of speed, you can enable the maximum text compression in
         the "Advanced compression parameter" dialog. Click the "Compression..."
         button on the  "Advanced" page of the archiving dialog to access it.
         You can also change this option permanently in the default compression
         profile;
         In the command line mode text compression can be enabled with the
         -mct switch;
      d) "Fastest" (-m1) compression mode now also supports several processor
         cores. In 4.11 it could only use a single processor core.
   2. RAR's 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 the number of cores.
   3. Changes in ZIP compression:
      a) ZIP compression now supports several processor cores resulting
         in noticeably higher performance in a multi-core environment.
         Single CPU ZIP compression is also faster than in 4.11;
      b) memory use for ZIP compression is increased to about 15 MB.
   4. Recovery volume creating and processing can now use several CPU cores
      resulting in higher speed. Though, typically hard drive seek speed is a
      limiting factor for recovery volumes, so this gain is most noticeable
       when working with a solid state drive.
   5. Now the allowed  value for -mt switch is 1 - 32, not 0 - 16 as before.
   6. "Find files" command can now search data in 7-Zip archives.
      Previously "Find files" did not support the .7z archive format.
   7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting
      modules anymore.
   8. "Save current settings" button in the "Advanced SFX options" dialog
      is now available only when converting an existing archive to SFX.
      Options saved with this button are applied only to convert to SFX
      operation.
      If you create or update an SFX archive, only the SFX options stored in
      the default compression profile are used. Options saved in the
      "Advanced SFX options" dialog are ignored for these operations.


 Version 4.11
   1. Bugs fixed:
      a) WinRAR 4.10 did not store the NTFS "Compressed" attribute, when creating RAR archives;
      b) WinRAR crashed in command line mode if the @filelist parameter was present and
          'filelist' did not exist. This bug affected only WinRAR.exe, not RAR.exe;
      c) if -x*\somefolder\* exclusion mask was specified when archiving and if the name of the 
          current folder contained 'somefolder', WinRAR excluded all files and stopped creating an
          archive;
      d) GUI self-extracting archives did not work in Windows Preinstallation Environment (Windows
          PE).

   
   Version 4.10
   1. WinRAR can create ZIP archives of practically any size:
      The 2 GB archive size and 65535 files maximum ZIP limitations of previous
      WinRAR versions are no longer valid.
   2. WinRAR can create multivolume ZIP archives, which are also known as
      split ZIP files.
      ZIP volumes have names like 'volname.zip', 'volname.z01', 'volname.z02'.
      Use a volume with ".zip" file extension in all archive processing
      operations like starting extraction or opening an archive.
      Unlike RAR volumes, ZIP volumes cannot be self-extracting.
      WinRAR needs to have access to all ZIP volumes of the multivolume file set
      at the same time, when creating or unpacking them. So it is impossible
      to create or unpack ZIP volumes on removable disks with one volume
      per disk. You need to place them all in the same folder.
   3. Added the high precision file time support in ZIP archives.
      WinRAR can store and extract modification, creation and last access
      file time in ZIP archives with 100 nanosecond precision.
      You need to set "High precision modification time" option in the "Time"
      part of the archiving dialog to store all 3 times in an archive.
      Set appropriate the "File time" options in the "Advanced" part of the extraction
      dialog to choose times to extract.
   4. Added support for Unicode names stored in ZIP extra field data.
      Different ZIP tools store Unicode names either in the file header
      or in the ZIP extra field and now WinRAR can correctly process both types
      of Unicode names.
   5. "Synchronize archive contents" option and -as command line switch are
      supported in ZIP format.
   6. Modifications of switch -ag behavior:
      a) -ag can be used with all RAR and WinRAR commands, not just
         with archiving only;
      b) 'N' format character behavior differs in archiving and non-archiving
         operations. When archiving, it is incremented until the first unused
         name is found. In non-archiving operations like extracting it selects
         the existing archive preceding the first unused name;
      c) 'I' format character allows you to specify minutes regardless of presence
         and position of 'H' (hours) in the format string. It can be used
         instead of 'M' (minutes), when you wish to place minutes before hours,
         or do not need hours at all.
   7. By default, WinRAR proposes to update an archive if you modified
      an open file or created any new files. New "Ignore modifications for"
      option in "Settings/Viewer" dialog allows for disabling such behavior.
      You can enter one or several file masks separated by spaces here
      and WinRAR will not prompt to update an archive if the file created
      or modified by viewer matches one of these masks.
   8. Changes in the volume size input field. Now you can select size units
      in the drop down list to the right of volume size. The previous way
      to define size modifiers, by entering 'k', 'm', etc. characters
      after the numeric size value, is also supported.
   9. Changes in "Predefined sizes" in "Define volume sizes" dialog.
      Floppies and ZIP disks are replaced by 5 MB and 100 MB volumes,
      added new entries for maximum FAT32 file size and for Blu-ray disks.
  10. New "Wipe files if password is set" option in "Options" page of
      archiving dialog. If you prefer to always delete encrypted files
      securely, you can enable "Wipe files if password is set"
      in the default compression profile.
  11. New "Wipe temporary files/Encrypted only" option in "Settings/Security".
      This is a slower and more secure delete for temporary files
      extracted from archives identified by WinRAR as encrypted.
      Quick delete is used for all other temporary files.
  12. Changes in "Convert archives" command:
      a) now it is possible to convert encrypted archives. Previously
         "Convert archives" command skipped them.
         Though, if you still prefer to skip them, you can do it by enabling
         the "Skip encrypted archives" option in the "Convert archives"
         dialog. This might be useful if you wish to run the conversion
         command in unattended mode, avoiding password prompts;
      b) special "rar2" archive type, which was specific for RAR 1.x
         and 2.x archives, has been removed. Now "rar" archive type controls
         conversion of all versions of RAR archives.
         Since the convert command does not need to detec thet RAR archive
         version any more, the initial search for archives is performed
         faster, resulting in a shorter delay before displaying the
         "Convert archives" dialog.
  13. New -log[fmt][=name] switch allows you to write archive and file names
      to the log file in the archiving command for RAR and ZIP formats and also
      in extracting, deleting and listing commands for RAR format.
      This switch is especially useful, when you need to further process
      an archive created with -ag or -v switches, because -log provides
      the archive name generated by WinRAR.
  14. New -@[+] switch allows processing of all parameters starting from
      '@' character either as file names (-@) or as file lists (-@+).
  15. "Setup program" SFX options are moved from "General" to the "Setup" page
      of the "Advanced SFX options" dialog. Both "Run after extraction"
      and "Run before extraction" are now multiline, so it is possible
      to specify several setup programs for the same SFX archive.
  16. "SetupCode" SFX script command instructs the SFX archive to wait
      for termination of the setup program and to return the exit code of that
      setup program, increased by 1000 as the exit code of SFX executable.
      GUI equivalent of this command is the "Wait and return exit code" option
      on the "Setup" page of the "Advanced SFX options" dialog.
  17. SFX does not support "S" (create in the top level of Start Menu)
      "Shortcut" command mode any more. Recent Windows versions do not allow
      programs to add items to the top of the Start Menu.
  18. Volume size in archiving and wizard dialogs can be specified as
      a decimal fraction. The decimal mark is defined by your Windows regional
      settings.
      -v command line switch also allows decimal fractions.
      In command line mode the dot (.) is always used as the decimal mark.
      For example, -v1.5g switch means 1.5 gigabytes.

   
Version 4.01
   1. Added support for file sizes stored in binary format in TAR archives.
      Some TAR archives use the binary size format instead of octal
      for files larger than 8 GB.   
   2. Bugs fixed:
      a) "Repair" command failed to properly reconstruct the structure
         of RAR archives which contained at least one file with a packed
         size exceeding 4 GB.
         This bug did not affect the recovery record based repair.
         It happened only if the recovery record was not found and WinRAR
         performed reconstruction of the archive structure;
      b) even if "Do not extract paths" option in "Advanced" part of
         extraction dialog was set as the default, WinRAR still unpacked
         file paths if called from Explorer context menu;
      c) after entering a wrong password for encrypted ZIP archive,
         sometimes WinRAR ignored subsequent attempts to enter a valid
         password;
      d) "Wizard" command did not allow creation of self-extracting 
         and multivolume archives, when compressing a single folder
         or a file without an extension;
      e) "Import settings from file" command did not restore multiline
         comments in WinRAR compression profiles;
      f) when converting RAR volumes having name1.name2.part#.rar name format,
         the "Convert archives" command erroneously removed the ".name2" name part.
         So the resulting archive had only a name1.rar filename instead of the expected
         name1.name2.rar;
      g) RAR could crash when creating a new archive with -agNNN switch
         if the archive number in a generated name was 110 or larger;
      h) WinRAR failed to display non-English file names in 7-Zip archives
         properly if they used a non-default code page. It was a display
         only problem, such names were unpacked correctly.

   
Version 4.00
   1. RAR decompression speed is improved. Depending on data type,
      decompression can be up to 30% faster than in previous versions.
      Both the general RAR algorithm and most of the special RAR multimedia
      methods benefit from this improvement. The only module of the RAR
      algorithm, which is not affected, is "Text compression" method.
   2. Changes in ISO support:
      a) UDF support is upgraded to UDF 2.50 revision. This makes it possible
         to unpack most Blu-ray ISO files;
      b) when browsing a UDF ISO file, the UDF revision number is displayed
         after the "UDF" format name in the WinRAR address bar and in the
         archive information dialog;
      c) WinRAR sets the folder modification date when unpacking folders
         stored in UDF and ISO9660 files.  
   3. Changes in password dialog:
      a) WinRAR uses the same format of password dialog both when archiving
         and extracting, so now the "Show password" option is also available
         when extracting;
      b) "Organize passwords..." button in the password dialog provides
         access to the password organizer interface, where you can specify
         your frequently used passwords. You will be able to access these
         saved passwords using the drop down list or autocomplete feature
         in the password dialog.
         It is important to know that saved passwords are not encrypted
         and anybody having access to your computer can view them.
         Use the  "Organize passwords" feature only if your computer is
         protected from unauthorized access;
      c) "Use for all archives" option is available in the password dialog
         when unpacking several archives at once. You can utilize it
         to apply an entered password to all archives.
         If you use this option with an empty password, WinRAR will skip
         all encrypted archives;
      d) Unlike previous versions, the password from the default compression
         profile is not used for extraction.         
         If you wish to use the same password for all extracting archives, press
         the "Organize passwords..." button in the password dialog
         and define a new password entry, specifying "*" file mask 
         in "Select for archives" field.   
   4. In Windows 7 WinRAR will also display the total operation progress on the
       WinRAR icon on the Windows taskbar. You can disable it using the
       "Taskbar progress bar" option on the WinRAR settings "General" page .
   5. Numerous Unicode support improvements allow for processing non-English
      file names more smoothly. These improvements include:
      a) better Unicode handling in WinRAR; "Rename", "Convert", "Find"
         and in other commands in the folder tree panel, in the password 
         request dialog and in many other parts of the WinRAR interface;
      b) correctly displayed Unicode names in WinRAR items in Explorer
         context menus;
      c) Unicode support in .lng files, making WinRAR localization
         possible for Unicode only languages.   
   6. Changes in -x switch syntax. Now you can specify a wildcard
      exclusion mask for folders. Such a mask must have the trailing '\'
      character, like -x*tmp*\ or -x*\temp\
   7. New "Extract relative paths" option in the "Advanced" part of the extraction
      dialog. If you browse an archive subfolder in a WinRAR shell and enable
      the "Extract relative paths" option, the path part up to and including
      the current subfolder will be removed from the extracted file paths.
         
      For example, if you are inside your "Backup\MyData" archive folder
      and extract the "Images" folder, it will be extracted as "Images",
      not as "Backup\MyData\Images".
      This option is the new default extraction mode, but you can change
      the default back to WinRAR 3.x style. Just select "Extract full paths"
      and then click "Save settings" in the "General" part of extraction dialog.   
   8. Windows 98, Windows Me and Windows NT are no longer not supported by WinRAR
      and WinRAR self-extracting modules. The minimum Windows version
      required for WinRAR 4.0 is Windows 2000.      
      If you need to run WinRAR on older Windows, you can download the
      previous WinRAR versions from ftp://ftp.rarlab.com/rar
   9. If a TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links
      and if the destination file system is NTFS, WinRAR will create these
      links when unpacking that archive. WinRAR will create symbolic links
      as symbolic and hard links as hard in Windows Vista and newer
      and it will create all links as hard in older Windows.
      If a destination file system is FAT32 or any other not supporting
      file links, WinRAR will skip links when unpacking TAR, TAR.GZ
      and TAR.BZ2 archives.   
  10. Recovery volume processing involves less disk seek operations
      resulting in higher performance.
  11. You can select the Windows 7 library in it's tree panel extraction dialog
      and WinRAR will use its default save location as the destination path.
  12. "Report" command allows selection of HTML, Unicode text and usual text
      as the output format for report files. Unlike previous WinRAR versions,
      WinRAR now preserves Unicode characters in reports when using HTML
      or Unicode text format. So non-English characters in file names
      will be displayed properly in such reports.   
  13. Message list in GUI SFX archives displays only operation status
      and error messages. It no longer contains the names of all extracted files.
      This change improves the speed and reduces the memory requirements
      for SFX archives containing a large number of files. This also makes it
      easier to locate error messages, because they are not hidden among
      extracted file names.
  14. GUI SFX archives displays the "Extract" button instead of "Install"
      if no "Setup" or "Presetup" commands are present in the archive
      comment. If you prefer the "Install" button, but do not need to
      execute any setup programs, you can add the "Setup=<>" command.  
  15. WinRAR displays the current percent above the operation progress bar
      when repairing an archive containing the recovery record and when
      processing recovery volumes.
  16. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte
      when creating RAR volumes on a disk using the FAT or FAT32 file system
      in volume size autodetecting mode. These file systems do not support
      4 GB and larger files.
  17. If the "Wait if other WinRAR copies are active" option is enabled
      and WinRAR waits for another copy, you can press the "Continue" button
      in the command progress window to force WinRAR to stop waiting.
      The "Continue" button now allows you to override the state of the
      "Wait if other WinRAR copies are active" option for the current operation.
  18. WinRAR displays one password request instead of two, when saving
      an encrypted file back to RAR or ZIP archive after modifying it
      in an external editor. Previous WinRAR versions usually requested
      the password twice, both when extracting the original file and when
      archiving its modified copy. Only RAR archives with encrypted
      file names were processed with the single password prompt.
  19. New error code 10 ("no files") is added to the list of error codes
      returned in command line mode by RAR and WinRAR. This new code
      can be returned by the archive, extract, delete and repair commands.
      It means that RAR did not find any files that matched the specified
      file or archive mask.  
  20. File name area in file overwrite dialog now occupies several lines 
      makeing it possible to display much longer names.  
  21. Switch -ep3 now converts not only disk letters, but also UNC paths.
      So \\server\share will be converted to __server\share when archiving and 
      it will be restored to the original \\server\share when extracting with -ep3.
  22. New "Background extraction" option in the "Advanced" part of the extraction
      dialog, puts WinRAR into the background when extracting files.
      You can save its default state with "Save settings" the button in the "General"
      part of the extraction dialog, just like other extraction options.
      "Background archiving" option from the default compression profile
      does not affect the extraction behavior anymore.
  23. "Mode..." button in the operation progress window is also enabled 
      when extracting or testing archives. It provides access to the 
      "Command parameters" dialog, where you can set the "Turn PC off when done"
      option for extraction and test operations.
      Previously this dialog was accessible only when archiving.
  24. Bugs fixed:
      a) renaming a file in an archive could also rename all other files
         with the same name in other folders of the same archive;
      b) previous versions displayed the wrong total packed size
         in "Info" command for multivolume CAB archives;
      c) in ZIP archives 'U' (update) and 'F' (fresh) commands could
         erroneously update even files not specified in the command line.
         It happened only for files in the current folder withs names matching
         files in the ZIP archive. This bug was not present in the 'A' (add)
         archiving mode.

 
  Version 3.93

   1. Bugs fixed:
      a) in WinRAR 3.92 -xd:\path\folder switch could also exclude folders,
         which path does not match the path specified in the switch
         and only the folder name is the same as specified;      
      b) switches -y -or did not work correctly together. Switch -or was
         ignored in presence of -y.

   
   Version 3.92
   1. If you start WinRAR command from Explorer context menu in multiple
      monitor configuration, the command dialog will be displayed
      on the same monitor as context menu. In previous versions it was
      always displayed on primary monitor.
   2. WinRAR "Compress and email..." context menu command adds the archive
      name to email subject. Previous versions left the subject blank.
   3. In RAR 3.91 -x switch could also exclude folders from archiving
      even if mask contained wilcard characters and did not contain a path.
      For example, -x*. excluded all those folders, which do not have
      the extension in the name. Now -x switch uses RAR 3.80 approach
      for masks without path, excluding folders only if mask does not
      contain wildcards and matches the folder name exactly.
   4. Bugs fixed:
      a) WinRAR 3.91 reported the incorrect "Unexpected end of archive"
         error, when opening an empty ZIP archive created with
         "New WinRAR ZIP archive" context menu command;
      b) if "Delete archive" option was enabled when unpacking several
         ZIP archives and if one of archives was damaged, WinRAR did not
         delete archives after the damaged one, even if they were unpacked
         successfully;
      c) if file matched two different masks in RarFiles.lst, WinRAR
         could select the last match. Normally, if neither of masks
         is a subset of another, the first match must be chosen.

 

 Version 3.91
   1. This version can decompress 7-Zip archives created with
      LZMA2 algorithm.
   2. Now a password is requested only once when unpacking 7z archives
      with encrypted file names from context menu. WinRAR 3.90 asked it
      twice.
   3. This version can unpack tar.bz2 archives consisting of several
      smaller bz2 streams merged together. Previous versions unpacked
      only the first nested bz2 stream in such composite archive.
   4. WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz)
      archives. Previous versions left this field blank for GZIP files.
   5. Bugs fixed:
      a) WinRAR 3.90 displayed "Save" button instead of "Open" or "OK"
         in "Find archive" dialog ("Open archive" command in "File" menu
         and "Browse..." command in archiving dialog);
      b) WinRAR could display incorrect file names when browsing malformed
         ZIP archives;
      c) WinRAR 3.90 failed to decompress LZH archives created with
         "-lh7-" algorithm;
      d) WinRAR 3.90 could fail to delete a part of files after archiving
         if delete to Recycle Bin was enabled. This bug was present
         when working in Windows XP, but not in Windows Vista and Windows 7;
      e) when unpacking ISO file using WinRAR "Extract files..." command
         in Explorer context menu, WinRAR could unpack same archived files
         twice during the same operation. It displayed the overwrite prompt
         when unpacking files for the second time;
      f) hexadecimal search in WinRAR 3.90 "Find" command and console RAR
         "ih" command failed to find matches if first byte in search string
         was greater than 127.

   
   Version 3.90
   1. WinRAR version for Windows x64 is available. If you use
      Windows x64, it is strongly recommended to install 64 bit
      WinRAR version. It provides a higher performance and better 
      shell integration than 32 bit version.
   2. RAR compression speed is improved for multi-core
      and multi-CPU systems. This improvement is most noticeable
      in Windows Vista and Windows 7 operating systems.
   3. "Remove duplicate folders from extraction path" option
      in "Settings/Compression" dialog is replaced by more universal
      "Remove redundant folders from extraction path" option.
      This option will eliminate redundant archive name based folders
      from extraction path if you unpack an archive with
      "Extract to DestName\" context menu command and if archive
      root folder contains only one folder and no files.
   4. Changes in "Extraction path and options" dialog:
      a) "New folder" button creates a new subfolder in currently
          selected folder;
      b) F2 key renames a selected folder in the folders tree;
      c) F5 key updated the tree pane contents;
      d) Del key removes a selected folder in the folders tree.
   5. You can enable "Show seconds" option in "Settings/File list"
      dialog if you wish to see seconds in file dates in file list
      in WinRAR shell.
   6. "Where to check for SFX archives" options group
      in "Settings/Integration/Context menus items" dialog lets
      you to control processing of SFX archives in context menus.
      For example, if you frequently right click ".exe" files
      on slow network disks, you can turn off "Network disks" options
      to minimize the delay before displaying the context menu.
   7. If you sort files by name in the file list in WinRAR shell,
      WinRAR will use the new logical file name sorting,
      same as in Windows Explorer, considering digits in file names
      by their numerical value. So files will be sorted as
      1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt.
      This new sort behavior is available in Windows XP Service Pack 2
      and newer.
   8. Ctrl+W key combination can be used to close the main WinRAR window
      also as WinRAR viewer windows. "View as Windows text" shortcut
      in WinRAR viewer changed from Ctrl+W to Ctrl+I.   
   9. New command line switch -r- disables recursion completely.
      So 'rar a -r- arc dirname' command will add only the empty
      dirname folder and ignore its contents. By default, if dirname
      does not include wildcards, RAR adds its contents even if
      -r switch is not specified.
  10. If used when extracting, the new command line switch -ai forces
      RAR to ignore file attributes. When using this switch,
      extracted files will always have attributes assigned by
      operating system to a newly created file by default.
  11. If output file name is not specified in "cw" command, console RAR
      will send comment data to stdout.
  12. When compressing stdin data with -si[name] switch, RAR sets 
      modification time of archived entry to current system time.
      Previous RAR versions did not fill this field, resulting in
      meaningless modification time for stdin.
  13. Message displayed when you place the mouse cursor on WinRAR
      tray icon includes the archive name now. Previously only
      time left and total percent were displayed for archiving operations.  
  14. New 'Shutdown' variable in 'Software\WinRAR\Policy' registry key
      allows to disable "Turn PC off when done" option for security reasons.
      Read "Configuration settings/Registry variables" for more details.
  15. Better shell extension performance. Now WinRAR context menu will be
      more responsive when working with thousands of selected files.
  16. Improved compatibility with high DPI Windows display mode.
  17. Bugs fixed:
      a) WinRAR could fail to open tar or tar.gz archive if such archive
         contained a file larger than 8 GB;      
      b) WinRAR context menu did not work properly in Windows 7 beta
         if icons in context menus were enabled and user clicked
         a file inside of Windows 7 Library folder;  
      c) previous WinRAR versions failed to rename files having 5 or more
         continuous spaces in the name. WinRAR shell does not display
         such spaces for safety reasons, because they can hide an actual
         file extension. But this security measure prevented the rename
         command to work properly.

   
Version 3.80
   1. Added support for ZIP archives containing Unicode file names
      in UTF-8 format. When creating ZIP archive, WinRAR stores 
      names in Unicode only if they cannot be stored correctly using 
      the current single byte character set.
   2. Added decompression support for WinZip AES encrypted ZIP archives.
   3. Improved Unicode support for RAR and ZIP archive names.
   4. "Ask before overwrite" and "Skip existing files" update modes
      are now available in archiving dialog. They allow to specify
      WinRAR behavior when updating already existing files in archive.
      Unlike already available "Fresh existing files only" and
      "Add and update files", these new modes ignore file date
      and compare only file names.
      Command line equivalents of these modes are:
      a) switch -o enables "Ask before overwrite" archiving mode;
      b) switch -o- enables "Skip existing files" archiving mode;
      c) switch -o+ enables "Overwrite all" mode (default for archiving).
   5. New "Add to context menu" option in "Profile parameters" dialog.
      If this option is on, the profile name will be displayed in Explorer
      context menus allowing to activate a profile from context menu. 
   6. New -cp switch allows to select a compression profile
      in command line mode. It is supported only by GUI WinRAR.exe,
      not by rar.exe.
   7. New "Options" page of archiving dialog contains the group of
      settings modifying the behavior of "Delete files after archiving"
      option from "General" page:
      a) Delete files. Delete files normally like in previous WinRAR
         versions.
      b) Move files to Recycle Bin. Deleted files are placed to
         Recycle Bin.
         Command line equivalent of this option is -dr switch.
      c) Wipe files. Before deleting file data are overwritten by
         zero bytes to prevent recovery of deleted files.
         Command line equivalent of this option is -dw switch.
      All these options have an effect only if "Delete files
      after archiving" is on. You can enable any of these options
      in the default compression profile to change the default
      behavior of "Delete files after archiving".
   8. WinRAR "Extraction path and options" dialog is now resizable.
      You can use the mouse to drag its border to the desired size 
      and provide more space for folder tree pane. WinRAR will store
      new dimensions of this dialog.
   9. New "Update" SFX script command and "Update mode" group
      of options in "Update" page of "Advanced SFX options" dialog.
      These command and options allow to check time and implement
      file time based updating;
  10. SFX script "Shortcut" command and "Add shortcut..." command
      in "Advanced SFX options" dialog now allow to specify
      an icon file containing an icon associated with shortcut.
  11. New "Wipe temporary files" option in "Settings/Security" dialog
      provides more secure, though slower, way to delete temporary
      WinRAR files.
  12. WinRAR and RAR display the total progress bar when unpacking
      a multivolume RAR archive if all volumes are present
      in the same folder.
  13. WinRAR and RAR automatically expand names of environment
      variables in list files. For example, a list file can contain
      lines like:
        %windir%\*.exe
        %USERPROFILE%\Desktop
      This feature is available only in Windows RAR version.
  14. Added support of TAR archives with non-zero "extra field" data.      
  15. Added support of TAR archives, which does not contain
      the end of archive entry consisting of 512 zero bytes.
  16. Improved Unicode support when dragging files from WinRAR window.
  17. Shift+Tab key combination can be used in main WinRAR window to 
      switch the input focus between interface elements (files, comment, 
      tree, address) in reverse order. In previous versions Shift+Tab 
      used the same order as Tab.
  18. Corrected a possible WinRAR crash when opening truncated 
      UDF ISO files.
