 Version 3.x is a major revamp of the SDK and comes with **many breaking changes**. The new implementation takes advantage of React Context along with many popular community libraries such as Reanimated V2 to deliver a superior chat experience. **Upgrading will require re-implementing** your integration but will yield performance and functional benefits. It is highly recommended you read the Cookbook and examine the SampleApp / TypeScriptMessaging apps before upgrading to understand what is required.
