+# v0.8.0
+- Added double hash mode, also known as lower power mode. `--av=2` and `--av=4`.
+- Added smart automatic CPU configuration. Default threads count now depends on size of the L3 cache of CPU.
+- Added CryptoNight-Lite support for AEON `-a cryptonight-lite`.
+- Added `--max-cpu-usage` option for auto CPU configuration mode.
+- Added `--safe` option for adjust threads and algorithm variations to current CPU.
+- No more manual steps to enable huge pages on Windows. XMRig will do it automatically.
+- Removed BMI2 algorithm variation.
+- Removed default pool URL.
+
+# v0.6.0
+- Added automatic cryptonight self test.
+- New software AES algorithm variation. Will be automatically selected if cpu not support AES-NI.
+- Added 32 bit builds.
+- Documented [algorithm variations](https://github.com/xmrig/xmrig#algorithm-variations).
+
+# v0.5.0
+- Initial public release.

 ### Windows
 It's complicated, you need [MSYS2](http://www.msys2.org/), custom libcurl build, and of course CMake too.
+
+Necessary MSYS2 packages:
+```
+pacman -Sy
+pacman -S mingw-w64-x86_64-gcc

+pacman -S mingw-w64-x86_64-cmake

 ```
 
+### Optional features
+`-DWITH_LIBCPUID=OFF` Disable libcpuid. Auto configuration of CPU after this will be very limited.
+`-DWITH_AEON=OFF` Disable CryptoNight-Lite support.
+
 ## Common Issues
 ### HUGE PAGES unavailable
 * Run XMRig as Administrator.
-* Enable SeLockMemoryPrivilege. For Windows 7 pro, or Windows 8 and above see [this article](https://msdn.microsoft.com/en-gb/library/ms190730.aspx).
+* Since version 0.8.0 XMRig automatically enable SeLockMemoryPrivilege for current user, but reboot or sign out still required. [Manual instruction](https://msdn.microsoft.com/en-gb/library/ms190730.aspx).
 
 ## Other information
-* Now only support 64 bit operating systems (Windows/Linux).
 * No HTTP support, only stratum protocol support.
 * No TLS support.
