    PhotonVoiceAPI:
FIXED: null reference when trying to set DebugEchoMode of dummy voice
FIXED: sending voice remove event to oneself when in DebugMode

v1.16
    PUNVoice:
CHANGED: removed all RequestUserAuthorization calls: crashes iOS builds, useful only in WebPlayer which is not supported since Unity 5.4.0
CHANGED: PhotonVoiceRecorder.updateAudioSource renamed to UpdateAudioSource and made public (call it when AudioSourceFactory has changed e.g.), it recreates local voice for any audio source (was Microphone only)
CHANGED: PhotonVoiceCreated receiver parameter updated in DelayProcessor
CHANGED: PhotonVoiceSettings.Encrypt option added to toggle encryption of all voice streams from settings
CHANGED: PhotonVoiceSettings.WorkInOfflineMode option added to allow voice client to connect in PUN offline mode
CHANGED: when connecting to self hosted server PUN's Nickname and UserId are used
CHANGED: updated Standard Assets' CrossPlatformInput inside PhotonVoice to remove warnings from newer Unity versions
CHANGED: updated PUN to 1.91v
CHANGED: PhotonVoiceSpeaker routes audio data to IAudioOut instance instead of AudioStreamPlayer; AudioStreamPlayer implements IAudioOut
ADDED: PS4AudioOut component that implements IAudioOut used in PS4 builds. 
NOTE: Audio output on the PS4 is now routed through Sony's native audio output APIs instead of through Unity's audio output APIs, when headphones are connected. This change was necessary to be able to support Sony's requirement that Voice Chat audio output must go to the headphones (when such are connected) even when other audio output goes to the speakers (which is not currently supported by Unity's audio output APIs).
    PhotonVoiceAPI:
FIXED: VoiceClient.removePlayerVoices iterated local voices channels list instead of remote
MINOR: not used 'encoder' parameter removed from VoiceClient.createLocalVoice (encoder passed implicitly in voiceFactory parameter if required)
CHANGED: VoiceClient.RemoveLocalVoice made public
FIXED: LocalVoiceFramed.PushDataBufferPool.Release always called with 'info' parameter to avoid reusing of buffers of wrong size during pool element size change with Init call (this happens for windows AudioIn native capturer e.g.) 
CHANGED: LocalVoice.IsTransmitting set to true if sendFrame was called in PushData or service (for readers) calls instead of checking built-in threshold based voice detector status
ADDED: AudioUtil::ForceToStereo()
