About Amazon MWAA versions
Amazon MWAA builds container images that bundle Apache Airflow releases with other common binaries and Python libraries. The image uses the Apache Airflow base install for the version you specify. When you create an environment, you specify an image version to use. Once an environment is created, it keeps using the specified image version until you upgrade it to a later version.
Latest version
Amazon MWAA supports more than one Apache Airflow version. If you do not specify an image version when you create an environment, Amazon MWAA creates an environment using the latest supported version of Apache Airflow.
