There is a filter preset for fix version 3.4.0. * React-native and react-navigation upgraded to version 4 * Cleaned up the way that assessment and evaluation data is handled * Removed a number of deprecated react native components * Removed legacy reducers including * assessment details reducer, assessment save progress reducer, & assessment draft reducer * Improved navigation flows * moved all navigation logic to root * updated navigation stacks * removed deprecated navigation code * **New and updated API endpoints**. Please upgrade your API version to 3.x (compatible with ME 1.16 and 1.17 releases) or you will encounter difficulties with triggering assessments.

You will also need this PR to receive the flag from ME: * --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
