 ### Input Recording Service improvements
 
 `InputRecordingService` and `InputPlaybackService` can now record and play back eye gaze input. Recording has been optimized to ensure a consistent framerate throughout the recording period while recording file size and save time are also reduced by about 50%. Saving and loading of recording files can now be performed asynchronously. Note the file format of the recording has changed in this MRTK version, please see [here](InputSimulation/InputAnimationFileFormat.md) for more information on the new version 1.1 specifications.
