Oct 31, 2018
  • General:
  • Added a new sensor API, initialized by passing SDL_INIT_SENSOR to SDL_Init(), and defined in SDL_sensor.h
  • Added an event SDL_SENSORUPDATE which is sent when a sensor is updated
  • Added SDL_GetDisplayOrientation() to return the current display orientation
  • Added an event SDL_DISPLAYEVENT which is sent when the display orientation changes

  • Added support for many other popular game controllers
  • Added SDL_JoystickGetDevicePlayerIndex(), SDL_JoystickGetPlayerIndex(), and SDL_GameControllerGetPlayerIndex() to get the player index for a controller. For XInput controllers this returns the XInput index for the controller.
  • Added SDL_GameControllerRumble() and SDL_JoystickRumble() which allow simple rumble without using the haptics API
  • Added SDL_GameControllerMappingForDeviceIndex() to get the mapping for a controller before it’s opened
  • Added the hint SDL_HINT_MOUSE_DOUBLE_CLICK_TIME to control the mouse double-click time
  • Added the hint SDL_HINT_MOUSE_DOUBLE_CLICK_RADIUS to control the mouse double-click radius, in pixels
  • Added SDL_HasColorKey() to return whether a surface has a colorkey active
  • Added SDL_HasAVX512F() to return whether the CPU has AVX-512F features
  • Added SDL_IsTablet() to return whether the application is running on a tablet
  • Added SDL_THREAD_PRIORITY_TIME_CRITICAL for threads that must run at the highest priority
  • Mac OS X:
  • Fixed black screen at start on Mac OS X Mojave
  • Linux:
  • Added SDL_LinuxSetThreadPriority() to allow adjusting the thread priority of native threads using RealtimeKit if available.
  • iOS:
  • Fixed Asian IME input
  • Android:
  • Updated required Android SDK to API 26, to match Google’s new App Store requirements
  • Added support for wired USB Xbox, PS4, and Nintendo Switch Pro controllers
  • Added support for relative mouse mode on Android 7.0 and newer (except where it’s broken, on Chromebooks and when in DeX mode with Samsung Experience 9.0)
  • Added support for custom mouse cursors on Android 7.0 and newer
  • Added the hint SDL_HINT_ANDROID_TRAP_BACK_BUTTON to control whether the back button will back out of the app (the default) or be passed to the application as SDL_SCANCODE_AC_BACK
  • Added SDL_AndroidBackButton() to trigger the Android system back button behavior when handling the back button in the application
  • Added SDL_IsChromebook() to return whether the app is running in the Chromebook Android runtime
  • Added SDL_IsDeXMode() to return whether the app is running while docked in the Samsung DeX

  • General:
  • Added an API to get common filesystem paths in SDL_filesystem.h: SDL_GetBasePath(), SDL_GetPrefPath()
  • Added an API to do optimized YV12 and IYUV texture updates: SDL_UpdateYUVTexture()
  • Added an API to get the amount of RAM on the system: SDL_GetSystemRAM()
  • Added a macro to perform timestamp comparisons with SDL_GetTicks(): SDL_TICKS_PASSED()
  • Dramatically improved OpenGL ES 2.0 rendering performance
  • Added OpenGL attribute SDL_GL_FRAMEBUFFER_SRGB_CAPABLE
  • Linux:
  • Fixed float audio support with the PulseAudio driver
  • Fixed missing line endpoints in the OpenGL renderer on some drivers
  • X11 symbols are no longer defined to avoid collisions when linking statically
  • Android:
  • IMPORTANT: You MUST get the updated SDLActivity.java to match C code
  • Moved EGL initialization to native code
  • Fixed the accelerometer axis rotation relative to the device rotation
  • Fixed race conditions when handling the EGL context on pause/resume
  • Touch devices are available for enumeration immediately after init
  • Raspberry Pi:
  • Added support for the Raspberry Pi, see README-raspberrypi.txt for details

New in SDL 1.2.14 (Oct 21, 2009)

  • General Notes:
  • Fixed flicker when resizing the SDL window
  • Fixed crash in SDL_SetGammaRamp()
  • Fixed freeze in SDL_memset() with 0 length when assembly code is disabled.
  • Added SDL_DISABLE_LOCK_KEYS environment variable to enable normal up/down events for Caps-Lock and Num-Lock keys.
  • Fixed audio quality problem when converting between 22050 Hz and 44100 Hz.
  • Fixed a threading crash when a few threads are rapidly created and complete.
  • Increased accuracy of alpha blending routines.
  • Fixed crash loading BMP files saved with the scanlines inverted.
  • Fixed mouse coordinate clamping if SDL_SetVideoMode() isn't called in response to SDL_VIDEORESIZE event.
  • Added doxygen documentation for the SDL API headers.
  • Unix Notes:
  • Fixed potential memory corruption due to assembly bug with SDL_revcpy()
  • Fixed crashes trying to detect SSE features on x86_64 architecture.
  • Fixed assembly for GCC optimized 50% alpha blending blits.
  • Added configure option --enable-screensaver, to allow enabling the screensaver by default.
  • Use XResetScreenSaver() instead of disabling screensaver entirely.
  • Removed the maximum window size limitation on X11.
  • Fixed SDL_GL_SWAP_CONTROL on X11.
  • Fixed setting the X11 window input hint.
  • Fixed distorted X11 window icon for some visuals.
  • Fixed detecting X11 libraries for dynamic loading on 64-bit Linux.
  • SDL_GL_GetAttribute(SDL_GL_SWAP_CONTROL) returns the correct value with GLX_SGI_swap_control.
  • Added SDL_VIDEO_FULLSCREEN_DISPLAY as a preferred synonym for SDL_VIDEO_FULLSCREEN_HEAD on X11.
  • The SDL_VIDEO_FULLSCREEN_DISPLAY environment variable can be set to 0 to place fullscreen SDL windows on the first Xinerama screen.
  • Added the SDL_VIDEO_FBCON_ROTATION environment variable to control output orientation on the framebuffer console. Valid values are: not set - Not rotating, no shadow; "NONE" - Not rotating, but still using shadow; "CW" - Rotating screen clockwise; "UD" - Rotating screen upside down; "CCW" - Rotating screen counter clockwise.
  • Fixed DirectFB detection on some Linux distributions.
  • Added code to use the PS3 SPE processors for YUV conversion on Linux.
  • Updated ALSA support to the latest stable API
  • ALSA is now preferred over OSS audio. (SDL_AUDIODRIVER=dsp will restore the previous behavior.)
