Some latest improvements include:

• Implemented playlist support in Audio component. Now TTS can be mixed together with flash-hosted files. Example usage - alarm jingle followed by TTS audio description.
• Implemented proper GPIO cleanup on Audio component destruction.
• Implemented proper GPIO cleanup on Temp Sensor destruction.
• General stability improvements, including audio decoding library updates.
• Improvements in ksIotFrameworkLib targeting Device Portal (device info, input data types) and device config storage.
