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

 

 ---------------------------------------------------------------------------

+2.0.6:

+---------------------------------------------------------------------------

+

+General:

+* Added cross-platform Vulkan graphics support in SDL_vulkan.h

+	SDL_Vulkan_LoadLibrary()

+	SDL_Vulkan_GetVkGetInstanceProcAddr()

+	SDL_Vulkan_GetInstanceExtensions()

+	SDL_Vulkan_CreateSurface()

+	SDL_Vulkan_GetDrawableSize()

+	SDL_Vulkan_UnloadLibrary()

+  This is all the platform-specific code you need to bring up Vulkan on all SDL platforms. You can look at an example in test/testvulkan.c

+* Added SDL_ComposeCustomBlendMode() to create custom blend modes for 2D rendering

+* Added SDL_HasNEON() which returns whether the CPU has NEON instruction support

+* Added support for inverted axes and separate axis directions in game controller mappings

+* Added functions to return information about a joystick before it's opened:

+	SDL_JoystickGetDeviceVendor()

+	SDL_JoystickGetDeviceProduct()

+	SDL_JoystickGetDeviceProductVersion()

+	SDL_JoystickGetDeviceType()

+	SDL_JoystickGetDeviceInstanceID()

+* Added functions to return information about an open joystick:

+	SDL_JoystickGetVendor()

+	SDL_JoystickGetProduct()

+	SDL_JoystickGetProductVersion()

+	SDL_JoystickGetType()

+	SDL_JoystickGetAxisInitialState()

+* Added functions to return information about an open game controller:

+	SDL_GameControllerGetVendor()

+	SDL_GameControllerGetProduct()

+	SDL_GameControllerGetProductVersion()

+* Added SDL_GameControllerNumMappings() and SDL_GameControllerMappingForIndex() to be able to enumerate the built-in game controller mappings

+* Added SDL_LoadFile() and SDL_LoadFile_RW() to load a file into memory

+* Added SDL_DuplicateSurface() to make a copy of a surface

+* Implemented non-power-of-two audio resampling, optionally using libsamplerate to perform the resampling

+* Added the hint SDL_HINT_AUDIO_RESAMPLING_MODE to control the quality of resampling

+* Added the hint SDL_HINT_RENDER_LOGICAL_SIZE_MODE to control the scaling policy for SDL_RenderSetLogicalSize():

+	"0" or "letterbox" - Uses letterbox/sidebars to fit the entire rendering on screen (the default)

+	"1" or "overscan"  - Will zoom the rendering so it fills the entire screen, allowing edges to be drawn offscreen

+* Added the hints SDL_HINT_MOUSE_NORMAL_SPEED_SCALE and SDL_HINT_MOUSE_RELATIVE_SPEED_SCALE to scale the mouse speed when being read from raw mouse input

+* Added the hint SDL_HINT_TOUCH_MOUSE_EVENTS to control whether SDL will synthesize mouse events from touch events

+

+Windows:

+* Added hints SDL_HINT_WINDOWS_INTRESOURCE_ICON and SDL_HINT_WINDOWS_INTRESOURCE_ICON_SMALL to specify a custom icon resource ID for SDL windows

+* The hint SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING is now on by default for compatbility with .NET languages and various Windows debuggers

+* Updated the GUID format for game controller mappings, older mappings will be cautomatically converted on load

+

+Linux:

+* Added an experimental KMS/DRM video driver for embedded development

+
