+## 🚨Important: Migration to Python KCL 2.2.0 or later with MultiLangDaemon - Credential Provider Changes Required
+Java KCL version 2.7.0 and later uses AWS SDK for Java 2.x instead of AWS SDK for Java 1.x. For the KCL Python 2.x versions,
+v2.2.0 is the first Python release to use Java KCL 2.7.0. All MultiLangDaemon users upgrading from earlier versions must update
+their credential provider configuration in the `.properties` file to use credentials provider name for AWS SDK for Java 2.x.
+Failure to do this will cause your multilang KCL application to fail during startup with credential provider construction errors.
+Please check the following link for the credentials provider mapping and MultiLangDaemon credentials provider configuration guide
