-			Building SDL
-		</H3>
-		<P>
-			Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. <CODE>SDL_VS2008.sln</CODE> This should open up the IDE.
-		</P>
-		<P>
-			There are different solution files for the various
-			versions of the IDE. Please use the appropriate version
-			2008, 2010, 2012 or 2013.
-		</P>
-		<P>
-			Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
-		</P>
-		<P>
-			This is done by right clicking on each project in turn (Projects are listed in 
-			the Workspace panel in the FileView tab), and selecting "Build".
-		</P>
-		<P>
-			You may get a few warnings, but you should not get any errors. You do have to 
-			have at least the DirectX 9 SDK installed, however. The latest 
-			version of DirectX can be downloaded from <A HREF="http://www.microsoft.com">Microsoft</A>.
-		</P>
-		<P>
-			Later, we will refer to the following .lib and .dll files that have just been

-			.
-			<br>
-			<STRONG><FONT color="#009900">VC7 Specific: Instead of doing this I find it easier to

 This is a list of major changes in SDL's version history.
 
+---------------------------------------------------------------------------
+2.0.22:
+---------------------------------------------------------------------------
+
+General:
+* Added the hint SDL_HINT_JOYSTICK_ROG_CHAKRAM to control whether ROG Chakram mice show up as joysticks
+
+
+---------------------------------------------------------------------------
+2.0.20:
+---------------------------------------------------------------------------
+
+General:
+* SDL_RenderGeometryRaw() takes a pointer to SDL_Color, not int. You can cast color data in SDL_PIXELFORMAT_RGBA32 format (SDL_PIXELFORMAT_ABGR8888 on little endian systems) for this parameter.
+* Improved accuracy of horizontal and vertical line drawing when using OpenGL or OpenGLES
+* Added the hint SDL_HINT_RENDER_LINE_METHOD to control the method of line drawing used, to select speed, correctness, and compatibility.
+
+Windows:
+* Fixed size of custom cursors
+
+Linux:
+* Fixed hotplug controller detection, broken in 2.0.18
+
+
+---------------------------------------------------------------------------
+2.0.18:
+---------------------------------------------------------------------------
+
+General:
+* The SDL wiki documentation and development headers are automatically kept in sync
+* Each function has information about in which version of SDL it was introduced
+* SDL-specific CMake options are now prefixed with 'SDL_'. Be sure to update your CMake build scripts accordingly!
+* Added the hint SDL_HINT_APP_NAME to let SDL know the name of your application for various places it might show up in system information
+* Added SDL_RenderGeometry() and SDL_RenderGeometryRaw() to allow rendering of arbitrary shapes using the SDL 2D render API
+* Added SDL_SetTextureUserData() and SDL_GetTextureUserData() to associate application data with an SDL texture
+* Added SDL_RenderWindowToLogical() and SDL_RenderLogicalToWindow() to convert between window coordinates and logical render coordinates
+* Added SDL_RenderSetVSync() to change whether a renderer present is synchronized with vblank at runtime
+* Added SDL_PremultiplyAlpha() to premultiply alpha on a block of SDL_PIXELFORMAT_ARGB8888 pixels
+* Added a window event SDL_WINDOWEVENT_DISPLAY_CHANGED which is sent when a window changes what display it's centered on
+* Added SDL_GetWindowICCProfile() to query a window's ICC profile, and a window event SDL_WINDOWEVENT_ICCPROF_CHANGED that is sent when it changes
+* Added the hint SDL_HINT_VIDEO_EGL_ALLOW_TRANSPARENCY to allow EGL windows to be transparent instead of opaque
+* SDL_WaitEvent() has been redesigned to use less CPU in most cases
+* Added SDL_SetWindowMouseRect() and SDL_GetWindowMouseRect() to confine the mouse cursor to an area of a window
+* You can now read precise mouse wheel motion using 'preciseX' and 'preciseY' event fields
+* Added SDL_GameControllerHasRumble() and SDL_GameControllerHasRumbleTriggers() to query whether a game controller supports rumble
+* Added SDL_JoystickHasRumble() and SDL_JoystickHasRumbleTriggers() to query whether a joystick supports rumble
+* SDL's hidapi implementation is now available as a public API in SDL_hidapi.h
+
+Windows:
+* Improved relative mouse motion over Windows Remote Desktop
