Public API Changes

1. Change

   New request: `vx_req_session_set_presence_custom_metadata` .

6. Deprecation

   Deprecated: `vx_get_noise_suppression_enabled` , `vx_set_noise_suppression_enabled` , `vx_get_noise_suppression_level` , and `vx_set_noise_suppression_level` . Use the new `vx_noise_reduction_webrtcns_*` functions instead.

7. Change

   New jitter compensation API: `vx_set_jitter_compensation_periods` and `vx_get_jitter_compensation_periods` .

8. Change

   New audio callbacks: `pf_on_local_audio_unit_before_signal_processing` , `pf_on_local_audio_unit_after_signal_processing` , and `pf_on_local_audio_unit_before_render` .
