This version fixes an issue where video was briefly stuttering after connecting to another user.

This version adds support for Single Peer Connection. When enabled, it reduces OS resource consumption, improves rate control, and in the case of mobile native devices, supports large sessions. See the documentation for otc_session_settings_set_single_peer_connection().
This version adds support for advanced noise suppression. This uses the Vonage Media Library to provide enhanced noise cancellation. See the documentation for the otc_publisher_set_audio_transformers() function. This was previously a beta feature.
This version adds support for advanced audio controls. See the documentation for otc_publisher_settings_set_stereo(), otc_publisher_settings_set_auto_gain_control(), otc_publisher_settings_set_noise_suppression(), otc_publisher_settings_set_echo_cancellation(), and otc_publisher_settings_set_disable_audio_processing(). This was previously a beta feature.

This version adds support for reading the Certificate Authority certificates in the trust store of the host so that it can use them as valid root certificates when connecting to OpenTok services.
This version adds support for Apple's requirement of the signature for the SDK.
This version adds support for advanced noise suppression. This uses the Vonage Media Library to provide enhanced noise cancellation. See the documentation for the otc_publisher_set_audio_transformers() function. This is a beta feature.
This version adds support for advanced audio controls. See the documentation for otc_publisher_settings_set_stereo(), otc_publisher_settings_set_auto_gain_control(), otc_publisher_settings_set_noise_suppression(), otc_publisher_settings_set_echo_cancellation(), and otc_publisher_settings_set_disable_audio_processing().

This version reduces the size of the SDK by removing the Vonage Media Library code. In order to use methods that use the Vonage Media Library, you must load the Vonage Media Library separately from the Vonage Video macOS SDK. This includes using the otc_publisher_set_video_transformers() and otc_publisher_set_audio_transformers() functions to apply audio and video transformers to the stream. For more information, see Vonage Media Library integration.
