WinRAR 5.11 Detail

Version 5.11 final

   1. WinRAR can unpack TAR archives containing folders with pax
      extended headers. Previous versions failed to unpack them.

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

   3. Bugs fixed:

      a) WinRAR 5.10 did not set "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 archive created with "Do not store paths" option
         included unnecessary empty name records for folders;

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

      e) deleting a file in RAR5 solid archive containing files stored
         with -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 size
         larger than 100.

1. New RAR 5.0 archiving format. You can use "RAR 5.0" option
      in archiving dialog or -ma command line switch to create
      RAR 5.0 archives.
      Older software including older WinRAR versions is not able to
      decompress RAR 5.0 archives, so if you plan to send an archive
      to other people, it is necessary to take the compatibility issue
      into consideration. You can select "RAR" instead of "RAR5" option
      in archiving dialog to create RAR 4.x archives compatible with
      previous WinRAR versions.

   2. Changes in 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 higher compression ratio and lower speed than RAR 4.x 4 MB.
         You can use "Dictionary size" archiving dialog option or -md
         switch 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, like -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 configurations;

      e) RAR 5.0 decompression can utilize several CPU cores.
         Though not to same extent as in 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 former local time, making file exchange among
         several 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 recovery record size is large enough, 5 and more,
      the new error correction scheme provides much higher resistance to
      multiple damages comparing to RAR 4.x recovery record.
      Smaller record, such as 1 - 2, or less random damage type 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.

      Additionally to usual data erasures, the new recovery record
      is able to detect deletions and insertions of much larger size
      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, when damaged sectors are filled by
      zeroes or any other data instead of cutting them out completely
      from resulting file.

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

      New recovery record is not based on 512 byte sectors anymore 
      and incorporates more complicated data structures. So it is impossible
      to specify its size in sectors. For RAR 5.0 archives the parameter of
      -rr[N] switch and rr[N] command is always treated as a percent of
      archive size regardless of presence of  character. Typically N
      recovery record can repair up to N of continuously damaged data
      and increases the archive size by only slightly more than N.
      Ability to fix multiple damages is proportional to N.

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

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

      If corrupt archive contains the recovery record, it might be possible
      to repair it even if recovery record validity test is failed.
      "Repair" command attempts to utilize even a partially damaged
      recovery record. So treat the negative recovery record test result
      as a reason to re-create the archive if original files are still
      available, but not as a reason to avoid "Repair" 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 to detect most of
         wrong passwords without 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 impossible
         guessing 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 to utilize 256 bit length BLAKE2sp hash
      ( ) instead of 32 bit CRC32 as a file checksum.
      Enable "Use BLAKE2 file checksum" option in "Options" page of
      archiving dialog or specify -htb command line switch to use BLAKE2

      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 file contents
      is the same. BLAKE2 error detection property is also stronger
      than in 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 the 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. 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
      "General" page of archiving dialog.
  10. You can use "Save symbolic links as links" option on "Advanced" page
      of archiving dialog to save and restore NTFS symbolic links
      and reparse points as links, so their contents is not archived.
      Command line equivalent of this option is -ol switch.

      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 RAR 5.0 archive format.
  11. Added extraction only support for 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) additionally to recovery data, RAR 5.0 REV files also store
         service information such as checksums of protected RAR files.
         So they are slightly larger than RAR volumes which they protect.
         If you plan to copy individual RAR and REV files to some removable
         media, you need to take it into account and specify RAR volume
         size by a few kilobytes smaller than media size.
  13. Maximum path length for files in RAR and ZIP archives is increased
      up to 2048 characters.
  14. Command line RAR returns the exit code 11 if it can detect that
      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 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 detect and display files in UTF-8
       and UTF-16 little endian encodings.

   18. UTF-16 little endian encoding is used in 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.
       In case of console RAR you need to delete the old rar.log manually,
       otherwide RAR will append UTF-16 messages to existing rar.log.

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

       rar r archive.rar destpath\
