If you enable this, you'll need to link with CoreBluetooth.framework and add something like this to your Info.plist:
<key>NSBluetoothPeripheralUsageDescription</key>
<string>MyApp would like to remain connected to nearby bluetooth Game Controllers and Game Pads even when you're not using the app.</string>
Note that apps submitted to the iOS App Store *must* use a modern iOS SDK (currently iOS 10 is probably the minimum), however the SDK used to build is separate from the minimum iOS version an app supports at runtime.

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.
The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.
It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.
And there's an additional error message for when ftell fails.
This work was done by Jacob Lifshay and Mark Callow; I'm just merging it
into revision control.

- Added new custom launch screen code. It uses the launch screen nib when available on iOS 8+, the launch images dictionary if the launch screen nib isn't available, and the old standard image names if the launch image dictionary isn't in the plist.
The launch screen is now hidden during the first call to SDL_PumpEvents rather than SDL_CreateWindow so apps can have the launch screen still visible if they do time-consuming loading after creating their window. It also fades out in roughly the same way as the system launch screen behavior.
It can be disabled by setting the SDL_IPHONE_LAUNCHSCREEN define in SDL_config_iphoneos.h to 0.
- A blank UIView is now created and displayed when the window is first created. The old behavior was to defer creating any view until SDL_GL_CreateContext, which prevented rotation, touch events, and other windowing-related things from working until then. This also makes it easier to use SDL_GetWindowWMInfo after creating a window.
- Moved the keyboard and animation callback code from SDL's UIView subclasses to its UIViewController subclass, which lets them work properly in all cases when a SDL window is valid, even before SDL_GL_CreateContext is called and after SDL_GL_DeleteContext is called.
- SDL_GL_CreateContext, SDL_GL_SwapWindow, SDL_GL_MakeCurrent, and SDL_GL_DeleteContext are more robust.
- Fixed some edge cases where SDL windows weren't rotating properly or their reported sizes were out of sync with their actual sizes.
- Removed all calls to [UIApplication setStatusBarOrientation:]. It doesn't seem to work as expected in all cases in recent iOS versions.
- Some code style cleanup.

SDL's code for exposing the accelerometer as a joystick on iOS currently uses UIAccelerometer, which was superseded by the CoreMotion framework and deprecated since iOS 5.
The UIAccelerometer code still works (for now), but it also throws deprecation warnings whenever SDL is built for iOS, since SDL's deployment target is no longer below iOS 5.
I've created a patch which replaces the old UIAccelerometer code with a replacement based on the CoreMotion framework. It has identical functionality (to SDL users), however iOS apps are now required to link to the CoreMotion framework when using SDL.

Now that SDL for iOS requires at least iOS 5.1 at runtime, there are several old codepaths in the UIKit backend which can be removed. I've attached a patch which does so.
Changed the CAS return value to bool, so it's efficient with OSAtomicCompareAndSwap32Barrier()
Added an atomic test adapted from code by Michael Davidsaver
