What's New in Winrar 4.20 Final :

Version 4.20

   1. Changes in RAR compression:

      a) RAR general compression algorithm is optimized for better
         utilization of several processor cores. While some speed gain
         is possible even in single processor mode, best results
         are achieved in multi-core environment.

         Speed gain depends on data type and average file size.
         Several cores are utilized more efficiently when compressing
         large files.

      b) we had to increase memory requirements to achieve higher
         compression speed. General RAR compression algorithm allocates
         about 120 MB comparing to 40 MB in WinRAR 4.11;

      c) RAR text compression algorithm cannot utilize several CPU cores
         efficiently, so its performance in multiprocessor environment
         is much lower than for general algorithm. Also its decompression
         speed is much lower than in general algorithm regardless of
         CPU number. So we decided to disable the text algorithm by default.

         If you need maximum possible compression ratio for plain text data
         regardless of speed, you can enable the text compression
         in "Advanced compression parameter" dialog. Press "Compression..."
         button on "Advanced" page of archiving dialog to access it.
         You can also change this option permanently in default compression
         profile;

         In the command line mode the text compression can be enabled
         with -mct switch;

      d) "Fastest" (-m1) compression mode also supports several processor
         cores now. In 4.11 it could use only a single processor core.

   2. RAR 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 a number of cores.

   3. Changes in ZIP compression:

      a) now ZIP compression supports several processor cores resulting
         in noticeably higher performance in 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 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 solid state drive.

   5. Now the allowed value for -mt switch is 1 - 32,
      not 0 - 16 as before.

   6. "Find files" command can search data in 7-Zip archives.
      Previously "Find files" did not support .7z archive format.

   7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting
      modules anymore.

   8. "Save current settings" button in "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 SFX archive, only SFX options stored
      in default compression profile are used. Options saved
      in "Advanced SFX options" dialog are ignored for these operations.
