| Log4j | When a project is imported to 8.0 from an earlier version that only supports Log4j<br>1, Log4j 1 is used by default to provide logging in 8.0 if Log4j is enabled in the<br>earlier version. You can migrate to Log4j 2, which provides significant<br>improvements over its predecessor Log4j 1, by selecting it from the<br>Log4j version drop-down list on the<br>Log4j view in the Project<br>Settings dialog box. All POM files for the project will be<br>synchronized when you change the Log4j version.<br><br><ul>Available in:<li>Cloud API Services Platform</li><li>Cloud Big Data</li><li>Cloud Big Data Platform</li><li>Cloud Data Fabric</li><li>Cloud Data Integration</li><li>Cloud Data Management Platform</li><li>Data Fabric</li><li>Qlik Cloud Enterprise Edition</li><li>Qlik Talend Cloud Enterprise Edition</li><li>Qlik Talend Cloud Premium Edition</li></ul><br><br>Information noteNote: If you need to<br>deploy your Jobs to Talend Cloud, the use of Log4j 2 requires Talend Remote Engine 2.8.1 or higher.
