　　WinRAR 5.20 Final:

　　Version 5.20

　　1. If Windows User Account Control prevents extracting or archiving

　　commands to create files in system protected folders, WinRAR attempts

　　to start its another copy with administrator privileges to complete

　　the operation. It is necessary to confirm privileges elevation

　　in response to User Account Control prompt to allow such second

　　WinRAR copy to run.

　　2. You can drag files in Explorer with right mouse button, drop them

　　to some folder and select WinRAR archiving commands in context menu

　　to create an archive with these files in the destination folder.

　　3. It is possible to use WinRAR.ini file instead of Registry to store

　　WinRAR settings. You may prefer such approach if you plan to install

　　WinRAR to removable media, such as USB flash drive, and then run it

　　on different computers.

　　See "WinRAR.ini file" topic in "Configuration settings" chapter

　　of WinRAR help for details.

　　4. Added extraction support for ZIP and ZIPX archives using

　　XZ compression algorithm.

　　5. If ZIP or ZIPX archive contains any compression algorithms except

　　usual "Store" or "Deflate", algorithm names are displayed

　　in "Version to extract" field of archive information dialog.

　　Algorithms with names unknown to WinRAR will be assigned "m"

　　name, where "num" is a compression algorithm numeric identifier.

　　6. "Open with WinRAR" command is available in Windows context menus

　　for archive formats supported by WinRAR. It can be turned off

　　with "Open with WinRAR (for usual archives)" option in WinRAR

　　"Settings/Integration/Context menu items..." dialog.

　　7. Command line RAR can read the default set of switches from rar.ini

　　file stored in RAR program folder. Previously it was possible to

　　define only the same set of switches for all RAR command with

　　"switches=" string. Now rar.ini also allows to specify

　　separate switch sets for individual RAR commands using

　　the following syntax:

　　switches_=

　　For example:

　　switches_a=-m5 -s

　　switches_x=-o+

　　8. Command "ch" supports switches -tl, -cu, -cl also for ZIP archives.

　　Previously "ch" allowed these switches only for RAR archive format.

　　9. For archive formats lacking file time information, such as .bz2,

　　.xz and .Z, WinRAR sets container archive modification time

　　to extracted files. It does not apply to tar.bz2, tar.xz and tar.Z,

　　which use file time stored in tar headers.

　　10. "Keep broken files" extraction option is supported for bzip2 archives.

　　11. WinRAR icon in Windows context menus is scaled up correctly

　　in high DPI screen modes such as 150% or 200% of normal text size.

　　12. It is possible to disable WinRAR "Benchmark" command with

　　"Benchmark" variable of HKEY_CURRENT_USERSoftwareWinRARPolicy

　　Registry key. In multi-user environment "Benchmark" command might

　　abuse shared computational resources. See "Registry variables" topic

　　in "Configuration settings" chapter of WinRAR help for more details.

　　13. Additionally to "sfxcmd" variable containing the entire command line,

　　SFX module sets "sfxpar" variable containing command line parameters

　　only, without leading SFX module name. These variables are set before

　　starting a program specified in "Setup" command.

　　14. File overwrite prompt in console RAR displays the size and modification

　　time for existing and new files.

　　15. When archiving from stdin
