> The latest updates to Daily's real-time audio and video APIs.

## Overview

May brings daily-js 0.90.0 and react-native-daily-js 0.85.0 with a critical fix for a Firefox 149 regression that prevented remote participant media from playing, and new `provider` and `sipCallId` fields across all dial-in and dial-out events for improved telephony observability. On the server side, presence endpoints now include `mtgSessionId`, and the VCS simulator gains video mode support along with a layer pinning fix.
