WinRAR - What's new in the latest version


   Version 5.30

   1. Information about the critical vulnerability in WinRAR self-extracting
      archives published in news in September and October 2015 is incorrect.
      Unfortunately mass media failed to recognize that what was described
      as WinRAR vulnerability is Windows OLE vulnerability patched
      in November 2014:

      https://technet.microsoft.com/en-us/library/security/ms14-064.aspx

      Even if unpatched, this Windows OLE vulnerability does not introduce
      new risk factors for WinRAR SFX archives.

      Please read http://rarlab.com/vuln_sfx_html2.htm for more details.

      No patches for WinRAR are needed.

   2. 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.

   3. 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.
         
   4. 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.

   5. 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.

   6. "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.

   7. "Skip encrypted" option in "Find files" dialog to silently skip
      encrypted archives while performing search command.
   
   8. 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.
   
   9. 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.

  10. 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.

  11. Sleep time parameter in -ri<priority>[:<sleep_time>] 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.

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

  13. 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.

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

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

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

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

  18. "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.

  19. 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%".

  20. Bugs fixed:

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

      b) console RAR "lt" command did not display seconds in file timestamp;

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

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