 This is a list of major changes in SDL's version history.
 
+---------------------------------------------------------------------------
+2.24.0:
+---------------------------------------------------------------------------
+
+General:
+* New version numbering scheme, similar to GLib and Flatpak.
+    * An even number in the minor version (second component) indicates
+      a production-ready stable release such as 2.24.0, which would have
+      been 2.0.24 under the old system.
+      * The patchlevel (micro version, third component) indicates a
+        bugfix-only update: for example, 2.24.1 would be a bugfix-only
+        release to fix bugs in 2.24.0, without adding new features.
+    * An odd number in the minor version indicates a prerelease such
+      as 2.23.0. Stable distributions should not use these prereleases.
+      * The patchlevel indicates successive prereleases, for example
+        2.23.1 and 2.23.2 would be prereleases during development of
+        the SDL 2.24.0 stable release.
+* Added SDL_bsearch() and SDL_utf8strnlen() to the stdlib routines
+* Added SDL_size_mul_overflow() and SDL_size_add_overflow() for better size overflow protection
+* Added functions to get the platform dependent name for a joystick or game controller:
+    * SDL_JoystickPathForIndex()
+    * SDL_JoystickPath()
+    * SDL_GameControllerPathForIndex()
+    * SDL_GameControllerPath()
+* Added SDL_GameControllerGetFirmwareVersion() and SDL_JoystickGetFirmwareVersion(), currently implemented for DualSense(tm) Wireless Controllers using HIDAPI
+* Added SDL_JoystickAttachVirtualEx() for extended virtual controller support
+* Added joystick event SDL_JOYBATTERYUPDATED for when battery status changes.
+* Added SDL_GUIDToString() and SDL_GUIDFromString() to convert between SDL GUID and string
+* Added SDL_HasLSX() and SDL_HasLASX() to detect LoongArch SIMD support
+
+Windows:
+* Added a D3D12 renderer implementation and SDL_RenderGetD3D12Device() to retrieve the D3D12 device associated with it
+* Added the hint SDL_HINT_WINDOWS_DPI_AWARENESS to set whether the application is DPI-aware. This hint must be set before initializing the video subsystem.
+* Added the hint SDL_HINT_WINDOWS_DPI_SCALING to control whether the SDL coordinates are in DPI-scaled points or pixels.
+
+Linux:
+* Added the hint SDL_HINT_VIDEO_WAYLAND_MODE_EMULATION to control whether to expose a set of emulated modes in addition to the native resolution modes available on Wayland
+* Added the hint SDL_HINT_LINUX_DIGITAL_HATS to control whether to treat hats as digital rather than checking to see if they may be analog
+* Added the hint SDL_HINT_LINUX_HAT_DEADZONES to control whether to use deadzones on analog hats
+
+---------------------------------------------------------------------------
+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
+
+
+---------------------------------------------------------------------------
+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
+

+Nokia N-Gage
+============
+
+SDL2 port for Symbian S60v1 and v2 with a main focus on the Nokia N-Gage
+(Classic and QD) by [Michael Fitzmayer](https://github.com/mupfdev).
+
+Compiling
+---------
+
+SDL is part of the [N-Gage SDK.](https://github.com/ngagesdk) project.
+The library is included in the
+[toolchain](https://github.com/ngagesdk/ngage-toolchain) as a
+sub-module.
+
+A complete example project based on SDL2 can be found in the GitHub
+account of the SDK: [Wordle](https://github.com/ngagesdk/wordle).
+
+Current level of implementation
+-------------------------------
+
+The video driver currently provides full screen video support with
+keyboard input.
+
+At the moment only the software renderer works.
+
+Audio is not yet implemented.
+
+Acknowledgements
+----------------
+
+Thanks to Hannu Viitala, Kimmo Kinnunen and Markus Mertama for the
+valuable insight into Symbian programming.  Without the SDL 1.2 port
+which was specially developed for CDoom (Doom for the Nokia 9210), this
+adaptation would not have been possible.
+
+I would like to thank my friends
+[Razvan](https://twitter.com/bewarerazvan) and [Dan
+Whelan](https://danwhelan.ie/), for their continuous support.  Without
+you and the [N-Gage community](https://discord.gg/dbUzqJ26vs), I would
+have lost my patience long ago.
+
+Last but not least, I would like to thank the development team of
+[EKA2L1](https://12z1.com/) (an experimental Symbian OS emulator). Your
+patience and support in troubleshooting helped me a lot.

+
+## Since 2.23.0
+
+SDL follows an "odd/even" versioning policy, similar to GLib, GTK, Flatpak
+and older versions of the Linux kernel:
+
+* The major version (first part) increases when backwards compatibility
+    is broken, which will happen infrequently.
+
+* If the minor version (second part) is divisible by 2
+    (for example 2.24.x, 2.26.x), this indicates a version of SDL that
+    is believed to be stable and suitable for production use.
+
+    * In stable releases, the patchlevel or micro version (third part)
+        indicates bugfix releases. Bugfix releases should not add or
+        remove ABI, so the ".0" release (for example 2.24.0) should be
+        forwards-compatible with all the bugfix releases from the
+        same cycle (for example 2.24.1).
+
+    * The minor version increases when new API or ABI is added, or when
+        other significant changes are made. Newer minor versions are
+        backwards-compatible, but not fully forwards-compatible.
+        For example, programs built against SDL 2.24.x should work fine
+        with SDL 2.26.x, but programs built against SDL 2.26.x will not
+        necessarily work with 2.24.x.
+
+* If the minor version (second part) is not divisible by 2
+    (for example 2.23.x, 2.25.x), this indicates a development prerelease
+    of SDL that is not suitable for stable software distributions.
+    Use with caution.
+
+    * The patchlevel or micro version (third part) increases with
+        each prerelease.
+
+    * Each prerelease might add new API and/or ABI.
+
+    * Prereleases are backwards-compatible with older stable branches.
+        For example, 2.25.x will be backwards-compatible with 2.24.x.
+
+    * Prereleases are not guaranteed to be backwards-compatible with
+        each other. For example, new API or ABI added in 2.25.1
+        might be removed or changed in 2.25.2.
+        If this would be a problem for you, please do not use prereleases.
+
+    * Only upgrade to a prerelease if you can guarantee that you will
+        promptly upgrade to the stable release that follows it.
+        For example, do not upgrade to 2.23.x unless you will be able to
+        upgrade to 2.24.0 when it becomes available.
+
+    * Software distributions that have a freeze policy (in particular Linux
+        distributions with a release cycle, such as Debian and Fedora)
+        should usually only package stable releases, and not prereleases.
+
+## Before 2.23.0
+
+Older versions of SDL followed a similar policy, but instead of the
+odd/even rule applying to the minor version, it applied to the patchlevel
+(micro version, third part). For example, 2.0.22 was a stable release
+and 2.0.21 was a prerelease.

+## LLVM and Intel C++ compiler support
+
+SDL will build with the Visual Studio project files with LLVM-based compilers, such as the Intel oneAPI C++
+compiler, but you'll have to manually add the "-msse3" command line option
+to at least the SDL_audiocvt.c source file, and possibly others. This may
+not be necessary if you build SDL with CMake instead of the included Visual
+Studio solution.

+Details are here: https://github.com/libsdl-org/SDL/issues/5186

+
+## OpenGL ES 2.x support
 
 SDL has support for OpenGL ES 2.x under Windows via two alternative
 implementations.
+
 The most straightforward method consists in running your app in a system with
 a graphic card paired with a relatively recent (as of November of 2013) driver
 which supports the WGL_EXT_create_context_es2_profile extension. Vendors known
 to ship said extension on Windows currently include nVidia and Intel.
 
-The other method involves using the ANGLE library (https://code.google.com/p/angleproject/)
-If an OpenGL ES 2.x context is requested and no WGL_EXT_create_context_es2_profile
-extension is found, SDL will try to load the libEGL.dll library provided by
-ANGLE.
-To obtain the ANGLE binaries, you can either compile from source from
-https://chromium.googlesource.com/angle/angle or copy the relevant binaries from
-a recent Chrome/Chromium install for Windows. The files you need are:

 If you compile ANGLE from source, you can configure it so it does not need the
 d3dcompiler_* DLL at all (for details on this, see their documentation).
 However, by default SDL will try to preload the d3dcompiler_46.dll to
