Upgrade to Azure Communication Services Calling JavaScript SDK 1.1.0 by 31 July 2021

Published date: July 06, 2021

On 24 August 2021, WebRTC APIs - specifically Plan B Session Description Protocol (SDP) API - will be retired in popular web browsers. To avoid browser compatibility risk and service disruption to your customers, please upgrade to Azure Communication Services’ Calling SDK 1.1.0 for JavaScript by 31 July 2021. While we still support earlier versions of JavaScript SDK 1.1.0, they will be marked as deprecated in NPM and other repositories.

Required action

Download the Calling JavaScript SDK 1.1.0 at NPM or using the commands below to upgrade your application:  

npm install @azure/communication-common --save

npm install @azure/communication-calling –save

This important but minor SDK update should be transparent to your application and does not require any change to your code.
