Once I ran build of my codecs collection on AppVeyor where my CMake script downloads latest SDL2 from HG repo, failed to link because of math functions conflict:
https://ci.appveyor.com/project/Wohlstand/audiocodecs/build/1.0.44
The revision is b9ff5f8b2303
There are both vanilla MinGW and MinGW-w64 are failed to build.

SDL_AddDisplayMode returns an SDL_bool corresponding to whether or not the given display mode was added or not. It will return SDL_FALSE if a matching display mode already exists in the display's list of display modes, which causes ownership of the mode driverdata to remain with the caller. Some video drivers ignore the return value of SDL_AddDisplayMode, so leak the driverdata memory when SDL_AddDisplayMode returns SDL_FALSE.

There is a typo in CMakeLists.txt that makes CMake exit with failure.
Change that causes the problem: (Notice the double ending brackets)
${SDL2_SOURCE_DIR}/src/video/*.c)
+ ${SDL2_SOURCE_DIR}/src/video/yuv2rgb/*.c)
Fix:
Just remove the first ending bracket resulting in:
${SDL2_SOURCE_DIR}/src/video/*.c
${SDL2_SOURCE_DIR}/src/video/yuv2rgb/*.c)

Here is the bug in latest SDL 2.0.8 development repo. It is obvious and simple to fix by correcting typos on six lines of code.
In src/video/SDL_yuv.c on lines 217, 249, 280, 321, 353, and 384 the wrong conversion functions are called for SDL_PIXELFORMAT_ABGR8888 and SDL_PIXELFORMAT_BGR888. Instead of ABGR functions, BGRA functions are called. These are typos.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

Remove static int vm_error and vm_event, use local variables instead.
This fixes unused variable errors when compiling with SDL_VIDEO_DRIVER_X11_XINERAMA undefined.
src/video/x11/SDL_x11modes.c:505:22: error: unused variable 'vm_error' [-Werror,-Wunused-variable]
src/video/x11/SDL_x11modes.c:505:12: error: unused variable 'vm_event' [-Werror,-Wunused-variable]

Add support to be able to set EGL_SURFACE_TYPE bits when creating an EGL config. This is usefule when wanting to create pixel buffer surfaces in custom video drivers.

In src\joystick\android\SDL_sysjoystick.c in SDL_SYS_JoystickDetect when SDL_GetTicks return number grater 2147483648 (after 24.85 days uptime) SDL_TICKS_PASSED(SDL_GetTicks(), timeout) return FALSE and Android_JNI_PollInputDevices is never calling.
And in JoystickByDeviceId - when search for newly added joystic - after SDL_SYS_JoystickDetect item not reinitilized, and always stay NULL, cause return NULL instead of added joystick.

A listener thread has been added to know when the native thread would end.
But now, it is more easy to only check that after the main function has returned. It's one thread less.

I noticed that after updating SDL to 2.0.6 my application now exports SDL_main.
At GitHub SDL mirror (branch 2.0.5) SDL_main prototyped as
extern C_LINKAGE int SDL_main(int argc, char *argv[]);
but at branch 2.0.6 prototype is
extern C_LINKAGE DECLSPEC int SDL_main(int argc, char *argv[]);
