 This is a list of major changes in SDL's version history.
 
+---------------------------------------------------------------------------
+2.0.22:
+---------------------------------------------------------------------------
+
+General:
+* Added SDL_RenderGetWindow() to get the window associated with a renderer
+* Added floating point rectangle functions:
+    * SDL_PointInFRect()
+    * SDL_FRectEmpty()
+    * SDL_FRectEquals()
+    * SDL_FRectEqualsEpsilon()
+    * SDL_HasIntersectionF()
+    * SDL_IntersectFRect()
+    * SDL_UnionFRect()
+    * SDL_EncloseFPoints()
+    * SDL_IntersectFRectAndLine()
+* Added SDL_IsTextInputShown() which returns whether the IME window is currently shown
+* Added SDL_ClearComposition() to dismiss the composition window without disabling IME input
+* Added SDL_TEXTEDITING_EXT event for handling long composition text, and a hint SDL_HINT_IME_SUPPORT_EXTENDED_TEXT to enable it
+* Added the hint SDL_HINT_MOUSE_RELATIVE_MODE_CENTER to control whether the mouse should be constrained to the whole window or the center of the window when relative mode is enabled
+* The mouse is now automatically captured when mouse buttons are pressed, and the hint SDL_HINT_MOUSE_AUTO_CAPTURE allows you to control this behavior
+* Added the hint SDL_HINT_VIDEO_FOREIGN_WINDOW_OPENGL to let SDL know that a foreign window will be used with OpenGL
+* Added the hint SDL_HINT_VIDEO_FOREIGN_WINDOW_VULKAN to let SDL know that a foreign window will be used with Vulkan
+* Added the hint SDL_HINT_QUIT_ON_LAST_WINDOW_CLOSE to specify whether an SDL_QUIT event will be delivered when the last application window is closed
+* Added the hint SDL_HINT_JOYSTICK_ROG_CHAKRAM to control whether ROG Chakram mice show up as joysticks
+
+Windows:
+* Added support for SDL_BLENDOPERATION_MINIMUM and SDL_BLENDOPERATION_MAXIMUM to the D3D9 renderer
+
+Linux:
+* Compiling with Wayland support requires libwayland-client version 1.18.0 or later
+* Added the hint SDL_HINT_X11_WINDOW_TYPE to specify the _NET_WM_WINDOW_TYPE of SDL windows
+* Added the hint SDL_HINT_VIDEO_WAYLAND_PREFER_LIBDECOR to allow using libdecor with compositors that support xdg-decoration
+
+Android:
+* Added SDL_AndroidSendMessage() to send a custom command to the SDL java activity
+

-.TH sdl2-config 1 "2012-02-20" "SDL 2.0"
-.SH NAME
-sdl2-config \- script to get information about the installed version of SDL
-.SH SYNOPSIS
-.B sdl2-config
-[ --prefix=
-.IR DIR ]
-[ --exec-prefix=
-.IR DIR ]
-[ --version ] [ --libs | --library-libs | --plugin-libs ] [ --cflags ]
-.SH DESCRIPTION
-.B sdl2-config
-is a tool that is used to configure and determine the compiler and linker
-flags that should be used to compile and link programs, libraries, and
-plugins that use SDL.  It is also used internally by the m4 macros that are
-included with SDL.
-.SH OPTIONS
-.TP
-.B --cflags
-Print the compiler flags that are necessary to compile a program or library
-that uses SDL.
-.TP
-.BI --exec-prefix= DIR
-If specified, use
-.I DIR
-instead of the installation exec prefix that SDL was build with when
-computing the output for the --cflags, --libs, --library-libs, and
---plugin-libs options.  This option must be specified before any of the
---cflags, --libs, --library-libs, and --plugin-libs options.
-.TP
-.B --libs
-Print the linker flags that are necessary to link a program that uses SDL.
-.TP
-.B --static-libs
-Print the linker flags that are necessary to statically link a program that uses SDL.
-.TP
-.B --library-libs
-Print the linker flags that are necessary to link a library that uses SDL.
-(This excludes any static objects required for linking, since these must be
-linked only by executable programs.)
-.TP
-.B --plugin-libs
-Print the linker flags that are necessary to link an SDL-using object that
-is to be accessed via
-.IR dlopen (3).
-This may include static objects with PIC symbol information.  This option
-should
-.B not
-be used for ordinary shared libraries or standalone applications.
-.TP
-.BI --prefix= DIR
-If specified, use PREFIX instead of the installation prefix that SDL was
-built with when computing the output for the --cflags, --libs,
---library-libs, and --plugin-libs options.  This option is also used for
-the exec prefix if --exec-prefix was not specified.  This option must be
-specified before any of the --cflags, --libs, --library-libs, and
---plugin-libs options.
-.TP
-.B --version
-Prints the currently installed version of SDL on standard output.
-.SH EXAMPLES
-.TP
-gcc -o main.o $(sdl2-config --cflags) main.c
-is how you might use
-.B sdl2-config
-to compile a C source file for an executable program.
-.TP
-gcc -o my_app $(sdl2-config --libs) main.o util.o
-is how you might use
-.B sdl2-config
-to link compiled objects into an executable program.

-gcc -o libSDL_nifty-2.0.so.0.0.1 $(sdl --library-libs) read.o write.o munge.o
-is how you might use
-.B sdl2-config
-to link compiled objects into a shared library.
-.TP
