Thanks to all the people who contributed code and feedback, SDL 2.0.10 is now available!  
[http://www.libsdl.org/download-2.0.php](http://www.libsdl.org/download-2.0.php)

In addition to lots of bug fixes and build improvements, here are the major changes in this release:

General:

- The SDL\_RW\* macros have been turned into functions that are available only in 2.0.10 and onward
- Added SDL\_SIMDGetAlignment(), SDL\_SIMDAlloc(), and SDL\_SIMDFree(), to allocate memory aligned for SIMD operations for the current CPU
- Added SDL\_RenderDrawPointF(), SDL\_RenderDrawPointsF(), SDL\_RenderDrawLineF(), SDL\_RenderDrawLinesF(), SDL\_RenderDrawRectF(), SDL\_RenderDrawRectsF(), SDL\_RenderFillRectF(), SDL\_RenderFillRectsF(), SDL\_RenderCopyF(), SDL\_RenderCopyExF(), to allow floating point precision in the SDL rendering API.
- Added SDL\_GetTouchDeviceType() to get the type of a touch device, which can be a touch screen or a trackpad in relative or absolute coordinate mode.
- The SDL rendering API now uses batched rendering by default, for improved performance
- Added SDL\_RenderFlush() to force batched render commands to execute, if you’re going to mix SDL rendering with native rendering
- Added the hint SDL\_HINT\_RENDER\_BATCHING to control whether batching should be used for the rendering API. This defaults to “1” if you don’t specify what rendering driver to use when creating the renderer.
- Added the hint SDL\_HINT\_EVENT\_LOGGING to enable logging of SDL events for debugging purposes
- Added the hint SDL\_HINT\_GAMECONTROLLERCONFIG\_FILE to specify a file that will be loaded at joystick initialization with game controller bindings
- Added the hint SDL\_HINT\_MOUSE\_TOUCH\_EVENTS to control whether SDL will synthesize touch events from mouse events
- Improved handling of malformed WAVE and BMP files, fixing potential security exploits

Linux:

- Removed the Mir video driver in favor of Wayland

iOS / tvOS:

- Added support for Xbox and PS4 wireless controllers in iOS 13 and tvOS 13
- Added support for text input using Bluetooth keyboards

Android:

- Added low latency audio using OpenSL ES
- Removed SDL\_HINT\_ANDROID\_SEPARATE\_MOUSE\_AND\_TOUCH (replaced by SDL\_HINT\_MOUSE\_TOUCH\_EVENTS and SDL\_HINT\_TOUCH\_MOUSE\_EVENTS)  
SDL\_HINT\_ANDROID\_SEPARATE\_MOUSE\_AND\_TOUCH=1, should be replaced by setting both previous hints to 0.  
SDL\_HINT\_ANDROID\_SEPARATE\_MOUSE\_AND\_TOUCH=0, should be replaced by setting both previous hints to 1.
- Added the hint SDL\_HINT\_ANDROID\_BLOCK\_ON\_PAUSE to set whether the event loop will block itself when the app is paused.

Nice, thanks. Is OpenSL ES the default now? I did notice some latency in audio on Android in previous versions. Wonder if forcing OpenSL ES (if it’s not default) would be safe if targeting Android 6.0+?

Yes, OpenSL ES is the default.

I can’t to compile new downloaded version of SDL-2.0.10-12951via CMake on Android, previous version (2.0.9) compiled fine.  
I don’t even know why it compiled hidapi PS4 and Xbox for Android gradle project, seems to it was added in **macro(CheckHIDAPI)**

Basically I don’t need SDL\_JOYSTICK so I would like to disable it but with  
set(SDL\_JOYSTICK OFF CACHE BOOL “” FORCE)  
set(HIDAPI OFF CACHE BOOL “” FORCE)  
set(SDL\_HAPTIC OFF CACHE BOOL “” FORCE)

I also receive a lot of compiler errors. How can I disable hidapi library without too many modifications in code ?

Finally I found a solution but I had to link all libraries as static:

> file(GLOB MY\_HIDAPI\_SOURCES ${SDL2\_SOURCE\_DIR}/src/hidapi/android/hid.cpp)  
> set(SOURCE\_FILES ${SOURCE\_FILES} ${MY\_HIDAPI\_SOURCES})

Than link all together in one big SDL-static library

To note, this: [tvOS Menu button with GameController API](https://discourse.libsdl.org/t/tvos-menu-button-with-gamecontroller-api/25798) is still a problem on tvOS with 2.0.10. Just me experiencing this?

There is also a bug report here: [https://bugzilla.libsdl.org/show\_bug.cgi?id=4531](https://bugzilla.libsdl.org/show_bug.cgi?id=4531)

I’ll try and find what caused it sometime soonish.

EDIT: I’ve fixed most of the problems using some hints and by ignoring remotes with only a few buttons (not opening them.) For Menu to return to the OS from the toplevel of the game, I needed this patch:

```

         return SDL_SCANCODE_RETURN;
     case UIPressTypeMenu:
         /* HIG says: "returns to previous screen" */
- return SDL_SCANCODE_ESCAPE;
+ return SDL_SCANCODE_MENU;
     case UIPressTypePlayPause:
         /* HIG says: "secondary button behavior" */
         return SDL_SCANCODE_PAUSE;

```

For some reason Menu was changed to Escape which makes it impossible to exit to the OS which I believe is part of Apple’s requirements of tvOS apps. For the record, I use this code in my event filter to handle the Menu button properly (I set pass\_menu\_to\_os on the title screen to true.)

```
case SDL_APP_DIDENTERFOREGROUND:
    SDL_SetHint(SDL_HINT_APPLE_TV_CONTROLLER_UI_EVENTS, "0");
    return 0;
case SDL_KEYDOWN:
case SDL_KEYUP:
    if (event->key.keysym.sym == SDLK_MENU && pass_menu_to_os) {
	    SDL_SetHint(SDL_HINT_APPLE_TV_CONTROLLER_UI_EVENTS, "1");
    }
return 1;
```

I’m surprised this was done in a minor version increase, as it’s an API breaking change. I thought SDL was pretty keen on backwards compatibility? As I read, that’s why SDL\_ShowCursor is global instead of per window.

We do occasionally change the API, especially around hints, which are not guaranteed functionality. We don’t ever intentionally break the ABI in minor versions.

Excuse my ignorance, but isn’t this this breaking the ABI? If I would swap out SDL2 for a newer version without recompiling anything it would suddenly start generating mouse events for touch events on android.

Also, [https://wiki.libsdl.org/CategoryHints](https://wiki.libsdl.org/CategoryHints) still needs to be updated, not sure who does that.
