1. WinRAR properly recognizes archives with a wrong file extension,
containing an archive in another format stored without compression.     

     For example, if host.rar, storing nested.zip inside, was renamed to
     host.zip, previous versions could display nested.zip contents
     when opening such host.zip. This version displays host.zip contents.

  2. Similarly to Windows Explorer, the first click on size and time columns
     in WinRAR file list sets the reverse sort mode with largest and latest
     files at the top.

  3. Switch -s=e performs the case insensitive file extension comparison
     in Windows. Unlike previous versions, solid statistics isn't reset
     anymore for file extensions differing only by case.

  4. If self-extracting archive attempts to extract files to a folder
     requring administrator rights and elevation prompt is cancelled by user,
     the archive quits silently instead of issuing the folder access error.

  5. Bugs fixed:

     a) WinRAR 7.20 couldn't unpack ZIP archives containing file comment
        fields;

     b) switch -tl didn't set the latest time when used with RAR 7.20
        "ch" command;
     
     c) extraction command didn't automatically replace device names
        like "aux", when unpacking archives containing such reserved names;
     
     d) if folder shortcut was double clicked in "Save WinRAR settings as"
        dialog when exporting WinRAR settings, folder shortcut itself was
        overwritten with settings data instead of opening a target folder
