Enhancements

  • Add soft button object and states, which allow for declaratively designing soft buttons with multiple states
• Allow the car window orientation exception to be disabled (Allow CarWindow to use multiple orientation ViewControllers (but not by default) #867)

• You can now batch send RPCs either as a batch, or sequentially, waiting for the previous RPC request to respond before sending the next one. This may be useful for batch sending addCommands or for sending a performInteraction immediately after the createInteraction finishes [SDL-0087] ([SDL 0087] Sequentially Send Multiple RPCs #723)

• Fix EA session not closing on RPC service timeout (EA session is not closed when start session for RPC service timed out #869)
• Fix EA session background not always receiving data in background (Cannot receive data from iAP session when app is suspended on iOS11 #835)
• Silence an output stream write warning (Silence output stream write error  #850)
• Improve SDLAddCommand initializer to fix an iconValue error (SDLAddCommand iconValue of nil results in INVALID_DATA #846)
• Fix SDLUploadFileOperation not finishing on error (SDLUploadFileOperation is not finished on error #860)
• Fix AudioStreamingState not being notified when LifecycleManager is ready (AudioStreamingState should be notified to SDLManagerDelegate when SDLLifecycleManager becomes ready #863)
• Fix some runtime main thread warnings ([UIApplication applicationState] called not from main thread #852)
• Work around a module ListFiles bug on previous SDL Core versions (Work around module ListFiles bug #827)
