Taking a lot of packages. I hope to get them all done this weekend.

2.0.6:

* 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 many game controllers, including the Nintendo Switch Pro Controller
* 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
* Added an experimental JACK audio driver
* 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

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