 This is a list of major changes in SDL's version history.
 
+---------------------------------------------------------------------------
+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

+* 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
+* Added the hint SDL_HINT_IME_SHOW_UI to show native UI components instead of hiding them (defaults off)
+
+Windows/UWP:

+
+Linux:
+* Added the hint SDL_HINT_SCREENSAVER_INHIBIT_ACTIVITY_NAME to set the activity that's displayed by the system when the screensaver is disabled
+* Added the hint SDL_HINT_LINUX_JOYSTICK_CLASSIC to control whether /dev/input/js* or /dev/input/event* are used as joystick devices
+* Added the hint SDL_HINT_JOYSTICK_DEVICE to allow the user to specify devices that will be opened in addition to the normal joystick detection
+* Added SDL_LinuxSetThreadPriorityAndPolicy() for more control over a thread priority on Linux
+
+Android:
+* Added support for audio output and capture using AAudio on Android 8.1 and newer
+* Steam Controller support is disabled by default, and can be enabled by setting the hint SDL_HINT_JOYSTICK_HIDAPI_STEAM to "1" before calling SDL_Init()
+
+Apple Arcade:
+* Added SDL_GameControllerGetAppleSFSymbolsNameForButton() and SDL_GameControllerGetAppleSFSymbolsNameForAxis() to support Apple Arcade titles
+
+iOS:
+* Added documentation that the UIApplicationSupportsIndirectInputEvents key must be set to true in your application's Info.plist in order to get real Bluetooth mouse events.

-2.  Install the iPhone SDL Application template by copying it to one of Xcode's template directories.  I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/Xcode/Project Templates/" and placing it there.
-3.  Start a new project using the template.  The project should be immediately ready for use with SDL.
 
-Here is a more manual method:

-2.  Build the SDL static library (libSDL2.a) for iOS and include them in your project.  Xcode will ignore the library that is not currently of the correct architecture, hence your app will work both on iOS and in the iOS Simulator.
-3.  Include the SDL header files in your project.
-4.  Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iOS provides its own UIApplicationDelegate.  Remove MainWindow.xib -- SDL for iOS produces its user interface programmatically.
-5.  Delete the contents of main.m and program your app as a regular SDL program instead.  You may replace main.m with your own main.c, but you must tell Xcode not to use the project prefix file, as it includes Objective-C code.

+# Mac OS X (aka macOS).
+
+These instructions are for people using Apple's Mac OS X (pronounced
+"ten"), which in newer versions is just referred to as "macOS".
+
+From the developer's point of view, macOS is a sort of hybrid Mac and
+Unix system, and you have the option of using either traditional
+command line tools or Apple's IDE Xcode.
+
+# Command Line Build
+
+To build SDL using the command line, use the standard configure and make
+process:
+
+```bash
+mkdir build
+cd build
+../configure
+make
+sudo make install
+```
+
+CMake is also known to work, although it continues to be a work in progress:
+
+```bash
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release ..
+make
+sudo make install
+```
+
+
+You can also build SDL as a Universal library (a single binary for both
+64-bit Intel and ARM architectures), by using the build-scripts/clang-fat.sh
+script.
+
+```bash
+mkdir build
+cd build
+CC=$PWD/../build-scripts/clang-fat.sh ../configure
+make
+sudo make install
+```
+
+This script builds SDL with 10.6 ABI compatibility on 64-bit Intel and 11.0
+ABI compatibility on ARM64 architectures.  For best compatibility you
+should compile your application the same way.
+
+Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
+(even if you target back to 10.6 systems). PowerPC support for Mac OS X has
+been officially dropped as of SDL 2.0.2. 32-bit Intel, using an older Xcode
+release, is still supported at the time of this writing, but current Xcode
+releases no longer support it, and eventually neither will SDL.
+
+To use the library once it's built, you essential have two possibilities:
+use the traditional autoconf/automake/make method, or use Xcode.
+
+
+# Caveats for using SDL with Mac OS X
+
+If you register your own NSApplicationDelegate (using [NSApp setDelegate:]),
+SDL will not register its own. This means that SDL will not terminate using
+SDL_Quit if it receives a termination request, it will terminate like a
+normal app, and it will not send a SDL_DROPFILE when you request to open a
+file with the app. To solve these issues, put the following code in your
+NSApplicationDelegate implementation:
+
+
+```objc
+- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
+{
+    if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) {
+        SDL_Event event;
+        event.type = SDL_QUIT;
+        SDL_PushEvent(&event);
+    }
+    
+    return NSTerminateCancel;
+}
+    
+- (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
+{
+    if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) {
+        SDL_Event event;
+        event.type = SDL_DROPFILE;
+        event.drop.file = SDL_strdup([filename UTF8String]);
+        return (SDL_PushEvent(&event) > 0);
+    }
+    
+    return NO;
+}
+```
+
+# Using the Simple DirectMedia Layer with a traditional Makefile
+
+An existing autoconf/automake build system for your SDL app has good chances
+to work almost unchanged on macOS. However, to produce a "real" Mac binary
+that you can distribute to users, you need to put the generated binary into a
+so called "bundle", which is basically a fancy folder with a name like
+"MyCoolGame.app".
+
+To get this build automatically, add something like the following rule to
+your Makefile.am:
+
+```make
+bundle_contents = APP_NAME.app/Contents
+APP_NAME_bundle: EXE_NAME
+	mkdir -p $(bundle_contents)/MacOS
+	mkdir -p $(bundle_contents)/Resources
+	echo "APPL????" > $(bundle_contents)/PkgInfo
+	$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
+```
+
+You should replace `EXE_NAME` with the name of the executable. `APP_NAME` is
+what will be visible to the user in the Finder. Usually it will be the same
+as `EXE_NAME` but capitalized. E.g. if `EXE_NAME` is "testgame" then `APP_NAME`
+usually is "TestGame". You might also want to use `@PACKAGE@` to use the
+package name as specified in your configure.ac file.
+
+If your project builds more than one application, you will have to do a bit
+more. For each of your target applications, you need a separate rule.
+
+If you want the created bundles to be installed, you may want to add this
+rule to your Makefile.am:
+
+```make
+install-exec-hook: APP_NAME_bundle
+	rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
+	mkdir -p $(DESTDIR)$(prefix)/Applications/
+	cp -r $< /$(DESTDIR)$(prefix)Applications/
+```
+
+This rule takes the Bundle created by the rule from step 3 and installs them
+into "$(DESTDIR)$(prefix)/Applications/".
+
+Again, if you want to install multiple applications, you will have to augment
+the make rule accordingly.
+
+But beware! That is only part of the story! With the above, you end up with
+a barebones .app bundle, which is double-clickable from the Finder. But
+there are some more things you should do before shipping your product...
+
+1. The bundle right now probably is dynamically linked against SDL. That
+   means that when you copy it to another computer, *it will not run*,
+   unless you also install SDL on that other computer. A good solution
+   for this dilemma is to static link against SDL. On OS X, you can
+   achieve that by linking against the libraries listed by
+
+   ```bash
+   sdl-config --static-libs
+   ```
+
+   instead of those listed by
+
+   ```bash
+   sdl-config --libs
+   ```
+
+   Depending on how exactly SDL is integrated into your build systems, the
+   way to achieve that varies, so I won't describe it here in detail
+
+2. Add an 'Info.plist' to your application. That is a special XML file which
+   contains some meta-information about your application (like some copyright
+   information, the version of your app, the name of an optional icon file,
+   and other things). Part of that information is displayed by the Finder
+   when you click on the .app, or if you look at the "Get Info" window.
+   More information about Info.plist files can be found on Apple's homepage.
+
+
+As a final remark, let me add that I use some of the techniques (and some
+variations of them) in [Exult](https://github.com/exult/exult) and
+[ScummVM](https://github.com/scummvm/scummvm); both are available in source on
+the net, so feel free to take a peek at them for inspiration!
+
+
+# Using the Simple DirectMedia Layer with Xcode
+
+These instructions are for using Apple's Xcode IDE to build SDL applications.
+
+## First steps
+
+The first thing to do is to unpack the Xcode.tar.gz archive in the
+top level SDL directory (where the Xcode.tar.gz archive resides).
+Because Stuffit Expander will unpack the archive into a subdirectory,
+you should unpack the archive manually from the command line:
+
+```bash
+cd [path_to_SDL_source]
+tar zxf Xcode.tar.gz
+```
+
+This will create a new folder called Xcode, which you can browse
+normally from the Finder.
+
+## Building the Framework
+
+The SDL Library is packaged as a framework bundle, an organized
+relocatable folder hierarchy of executable code, interface headers,
+and additional resources. For practical purposes, you can think of a 
+framework as a more user and system-friendly shared library, whose library
+file behaves more or less like a standard UNIX shared library.
+
+To build the framework, simply open the framework project and build it. 
+By default, the framework bundle "SDL.framework" is installed in 
+/Library/Frameworks. Therefore, the testers and project stationary expect
+it to be located there. However, it will function the same in any of the
+following locations:
+
+* ~/Library/Frameworks
+* /Local/Library/Frameworks
+* /System/Library/Frameworks
+
+## Build Options
+
+There are two "Build Styles" (See the "Targets" tab) for SDL.
+"Deployment" should be used if you aren't tweaking the SDL library.
+"Development" should be used to debug SDL apps or the library itself.
+
+## Building the Testers
+
+Open the SDLTest project and build away!
+
+## Using the Project Stationary
+
+Copy the stationary to the indicated folders to access it from
+the "New Project" and "Add target" menus. What could be easier?
+
+## Setting up a new project by hand
+
+Some of you won't want to use the Stationary so I'll give some tips:
+
+(this is accurate as of Xcode 12.5.)
+
+* Click "File" -> "New" -> "Project...
+* Choose "macOS" and then "App" from the "Application" section.
+* Fill out the options in the next window. User interface is "XIB" and
+  Language is "Objective-C".
+* Remove "main.m" from your project
+* Remove "MainMenu.xib" from your project
+* Remove "AppDelegates.*" from your project
+* Add "\$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
+* Add "\$(HOME)/Library/Frameworks" to the frameworks search path
+* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
+* Add your files
+* Clean and build
+
+## Building from command line
+
+Use `xcode-build` in the same directory as your .pbxproj file
+
+## Running your app
+
+You can send command line args to your app by either invoking it from
+the command line (in *.app/Contents/MacOS) or by entering them in the
+Executables" panel of the target settings.
+    
+# Implementation Notes
+
+Some things that may be of interest about how it all works...
+
+## Working directory
+
+In SDL 1.2, the working directory of your SDL app is by default set to its
+parent, but this is no longer the case in SDL 2.0. SDL2 does change the
+working directory, which means it'll be whatever the command line prompt
+that launched the program was using, or if launched by double-clicking in
+the finger, it will be "/", the _root of the filesystem_. Plan accordingly!
+You can use SDL_GetBasePath() to find where the program is running from and
+chdir() there directly.
+
+
+## You have a Cocoa App!
+
+Your SDL app is essentially a Cocoa application. When your app
+starts up and the libraries finish loading, a Cocoa procedure is called,
+which sets up the working directory and calls your main() method.
+You are free to modify your Cocoa app with generally no consequence
+to SDL. You cannot, however, easily change the SDL window itself.
+Functionality may be added in the future to help this.

+- eComStation:
+
+  If you have previously installed SDL2, make a Backup copy of SDL2.dll
+  located in D:\ecs\dll (where D: is disk on which installed eComStation).
+  Stop all programs running with SDL2. Copy SDL2.dll to D:\ecs\dll
+
+- OS/2:
+
+  Copy SDL2.dll to any directory on your LIBPATH.  If you have a previous
+  version installed, close all SDL2 applications before replacing the old
+  copy.  Also make sure that any other older versions of DLLs are removed
+  from your system.
+
+
+Joysticks in SDL2:
+------------------
+
+The joystick code in SDL2 is a direct forward-port from the SDL-1.2 version.
+Here is the original documentation from SDL-1.2:
+
+The Joystick detection only works for standard joysticks (2 buttons, 2 axes
+and the like). Therefore, if you use a non-standard joystick, you should
+specify its features in the SDL_OS2_JOYSTICK environment variable in a batch
+file or CONFIG.SYS, so SDL applications can provide full capability to your
+device. The syntax is:
+
+SET SDL_OS2_JOYSTICK=[JOYSTICK_NAME] [AXES] [BUTTONS] [HATS] [BALLS]
+
+So, it you have a Gravis GamePad with 4 axes, 2 buttons, 2 hats and 0 balls,
+the line should be:
+
+SET SDL_OS2_JOYSTICK=Gravis_GamePad 4 2 2 0
+
+If you want to add spaces in your joystick name, just surround it with
+quotes or double-quotes:
+
+SET SDL_OS2_JOYSTICK='Gravis GamePad' 4 2 2 0
+
+or
+
+SET SDL_OS2_JOYSTICK="Gravis GamePad" 4 2 2 0
+
+   Note however that Balls and Hats are not supported under OS/2, and the
+value will be ignored... but it is wise to define these correctly because
+in the future those can be supported.
+
+   Also the number of buttons is limited to 2 when using two joysticks,
+4 when using one joystick with 4 axes, 6 when using a joystick with 3 axes
+and 8 when using a joystick with 2 axes. Notice however these are limitations
+of the Joystick Port hardware, not OS/2.

+RISC OS
+=======
+
+Requirements:
+
+* RISC OS 3.5 or later.
+* [SharedUnixLibrary](http://www.riscos.info/packages/LibraryDetails.html#SharedUnixLibraryarm).
+* [DigitalRenderer](http://www.riscos.info/packages/LibraryDetails.html#DRendererarm), for audio support.
+* [Iconv](http://www.netsurf-browser.org/projects/iconv/), for `SDL_iconv` and related functions.
+
+
+Compiling:
+----------
+
+Currently, SDL2 for RISC OS only supports compiling with GCCSDK under Linux. Both the autoconf and CMake build systems are supported.
+
+The following commands can be used to build SDL2 for RISC OS using autoconf:
+
+    ./configure --host=arm-unknown-riscos --prefix=$GCCSDK_INSTALL_ENV --disable-gcc-atomics
+    make
+    make install
+
+The following commands can be used to build SDL2 for RISC OS using CMake:
+
+    cmake -Bbuild-riscos -DCMAKE_TOOLCHAIN_FILE=$GCCSDK_INSTALL_ENV/toolchain-riscos.cmake -DRISCOS=ON -DCMAKE_INSTALL_PREFIX=$GCCSDK_INSTALL_ENV -DCMAKE_BUILD_TYPE=Release -DSDL_GCC_ATOMICS=OFF
+    cmake --build build-riscos
+    cmake --build build-riscos --target install
+
+
+Current level of implementation
+-------------------------------
+
+The video driver currently provides full screen video support with keyboard and mouse input. Windowed mode is not yet supported, but is planned in the future. Only software rendering is supported.
+
+The filesystem APIs return either Unix-style paths or RISC OS-style paths based on the value of the `__riscosify_control` symbol, as is standard for UnixLib functions.
+
+The audio, loadso, thread and timer APIs are currently provided by UnixLib.
+
+GCC atomics are currently broken on some platforms, meaning it's currently necessary to compile with `--disable-gcc-atomics` using autotools or `-DSDL_GCC_ATOMICS=OFF` using CMake.
+
+The joystick, locale and power APIs are not yet implemented.

+Using SDL with Microsoft Visual C++
+===================================
+
+### by [Lion Kimbro](mailto:snowlion@sprynet.com) with additions by [James Turk](mailto:james@conceptofzero.net)
+
+You can either use the precompiled libraries from the [SDL](https://www.libsdl.org/download.php) web site, or you can build SDL
+yourself.
+
+### Building SDL
+
+0. To build SDL, your machine must, at a minimum, have the DirectX9.0c SDK installed. It may or may not be retrievable from
+the [Microsoft](https://www.microsoft.com) website, so you might need to locate it [online](https://duckduckgo.com/?q=directx9.0c+sdk+download&t=h_&ia=web).
+_Editor's note: I've been able to successfully build SDL using Visual Studio 2019 **without** the DX9.0c SDK_
+
+1. Open the Visual Studio solution file at `./VisualC/SDL.sln`.
+
+2. Your IDE will likely prompt you to upgrade this solution file to whatever later version of the IDE you're using. In the `Retarget Projects` dialog,
+all of the affected project files should be checked allowing you to use the latest `Windows SDK Version` you have installed, along with
+the `Platform Toolset`.
+   
+If you choose *NOT* to upgrade to use the latest `Windows SDK Version` or `Platform Toolset`, then you'll need the `Visual Studio 2010 Platform Toolset`.
+
+3. Build the `.dll` and `.lib` files by right clicking on each project in turn (Projects are listed in the _Workspace_ 
+panel in the _FileView_ tab), and selecting `Build`.
+
+You may get a few warnings, but you should not get any errors.
+
+Later, we will refer to the following `.lib` and `.dll` files that have just been generated:
+
+-   `./VisualC/Win32/Debug/SDL2.dll` or `./VisualC/Win32/Release/SDL2.dll`
+-   `./VisualC/Win32/Debug/SDL2.lib` or `./VisualC/Win32/Release/SDL2.lib`
+-   `./VisualC/Win32/Debug/SDL2main.lib` or `./VisualC/Win32/Release/SDL2main.lib`
+
+_Note for the `x64` versions, just replace `Win32` in the path with `x64`_
+
+### Creating a Project with SDL
+
+- Create a project as a `Win32 Application`.
+
+- Create a C++ file for your project.
+
+- Set the C runtime to `Multi-threaded DLL` in the menu:
+`Project|Settings|C/C++                  tab|Code Generation|Runtime Library `.
+
+- Add the SDL `include` directory to your list of includes in the menu:
+`Project|Settings|C/C++ tab|Preprocessor|Additional include directories `
+
+*VC7 Specific: Instead of doing this, I find it easier to add the
+include and library directories to the list that VC7 keeps. Do this by
+selecting Tools|Options|Projects|VC++ Directories and under the "Show
+Directories For:" dropbox select "Include Files", and click the "New
+Directory Icon" and add the [SDLROOT]\\include directory (e.g. If you
+installed to c:\\SDL\\ add c:\\SDL\\include). Proceed to change the
+dropbox selection to "Library Files" and add [SDLROOT]\\lib.*
+
+The "include directory" I am referring to is the `./include` folder.
+
+Now we're going to use the files that we had created earlier in the *Build SDL* step.
+
+Copy the following file into your Project directory:
+
+-   `SDL2.dll`
+
+Add the following files to your project (It is not necessary to copy them to your project directory):
+
+-   `SDL2.lib`
+-   `SDL2main.lib`
+
+To add them to your project, right click on your project, and select
+`Add files to project`.
+
+**Instead of adding the files to your project, it is more desirable to add them to the linker options: Project|Properties|Linker|Command Line
+and type the names of the libraries to link with in the "Additional Options:" box. Note: This must be done for each build configuration
+(e.g. Release,Debug).**
+
+### Hello SDL2
+
+Here's a sample SDL snippet to verify everything is setup in your IDE:
+
+```
+    #include "SDL.h"
+
+    int main( int argc, char* argv[] )
+    {
+        const int WIDTH = 640;
+        const int HEIGHT = 480;
+        SDL_Window* window = NULL;
+        SDL_Renderer* renderer = NULL;
+
+        SDL_Init(SDL_INIT_VIDEO);
+        window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN);
+        renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
+ 
+        SDL_DestroyRenderer(renderer);
+        SDL_DestroyWindow(window);
+        SDL_Quit();
+        return 0;
+    }
+ ```               
+
+### That's it!
+
+I hope that this document has helped you get through the most difficult part of using the SDL: installing it. 
+Suggestions for improvements should be posted to the [Github Issues](https://github.com/libsdl-org/SDL/issues).

+* gles1/gles2 support and renderers are disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PVR=ON`
+  These renderers support 720p and 1080i resolutions. These can be specified with: 
+  `SDL_setenv("VITA_RESOLUTION", "720", 1);` and `SDL_setenv("VITA_RESOLUTION", "1080", 1);`
+* gles2 support via PIB is disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PIB=ON`
+* By default SDL emits mouse events for touch events on every touchscreen.  
+  Vita has two touchscreens, so it's recommended to use `SDL_SetHint(SDL_HINT_TOUCH_MOUSE_EVENTS, "0");` and handle touch events instead.
+  Individual touchscreens can be disabled with:
+  `SDL_setenv("VITA_DISABLE_TOUCH_FRONT", "1", 1);` and `SDL_setenv("VITA_DISABLE_TOUCH_BACK", "1", 1);`
+* Support for L2/R2/R3/R3 buttons, haptic feedback and gamepad led only available on PSTV, or when using external ds4 gamepad on vita.
