介绍：（哥就不翻译了，有兴趣的同学想必也看得懂）

我就简单总结一下吧：
1. 新的RAR5.0可以进一步提高压缩率，比如原来一个100M的文件你压了之后是50M，现在使用5.0算法可能就可以压到40M；
2.高压缩率要以付出内存为代价，8G内存的机器可以勉强使用512M的字典；
3.RAR5.0兼容老版本，但老版本不兼容5.0；
4.RAR5.0使用了更好的修复算法。

Version 5.00 beta 3

1. Fixed XZ archive support, which did not work in beta 2.

2. "Convert" command did not allow to use compression dictionaries
   exceeding 4 MB.

3. If both encryption password and archive comment were specified
   when creating RAR archive, archive comment was not added.

4. "View as Unicode (UTF-8)" command in internal viewer did not work,
   so UTF-8 files were displayed correctly only if their encoding
   was detected by viewer automatically.

5. Maximum compression dictionary size when running in Windows XP x86
   is reduced to 128 MB. WinRAR cannot allocate enough memory to
   create archives with 256 MB dictionary in Windows XP x86.

6. Corrections in relative path processing, such as "..\arcname.rar" name
   in archiving dialog or "WinRAR foldername" in the command line.

Version 5.00 beta 2

1. When adding an incompressible file to non-solid RAR archive,
   beta 1 could duplicate the first megabyte of archived file,
   resulting in damaged file.

2. "Add to archive..." context menu command could place a created archive
   to a wrong folder.

Version 5.00 beta 1

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
   ( https://blake2.net ) 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
   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 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\
