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.
Apache Airflow versions
The following Apache Airflow versions are supported on Amazon Managed Workflows for Apache Airflow.
Note
-
Beginning with Apache Airflow v2.2.2, Amazon MWAA supports installing Python requirements, provider packages, and custom plugins directly on the Apache Airflow web server.
-
Beginning with Apache Airflow v2.7.2, your requirements file must include a

Important
You are responsible for keeping your Amazon MWAA versions current. AWS urges all customers to upgrade their Amazon MWAA environments to the latest version in order to benefit from the most current security, privacy, and availability safeguards. If you operate your environment on an unsupported version or software past the deprecation date, referred to as the legacy version, you face a greater likelihood of security, privacy, and operational risks, including downtime events. By operating your Amazon MWAA environment on a legacy version, you confirm that you understand and knowingly assume these risks, and you agree to complete your upgrade to the latest version as soon as possible. Continued operation of your environment on a legacy version is subject to the agreement governing your use of the AWS services.
Legacy versions are not considered generally available, and AWS no longer provides support for the legacy version. As a result, AWS may place limits on the access to or use of any legacy version at any time, if AWS determines that the legacy version poses a security or liability risk, or a risk of harm, to the services, AWS, its Affiliates, or any other third party. Your decision to continue running Your workloads on a legacy version might result in Your content becoming unavailable, corrupted, or unrecoverable. Environments running on a legacy version are subject to Service Level Agreement (SLA) exceptions.
Environments, and related software, running on a legacy version might contain bugs, errors, defects, and harmful components. Accordingly, and notwithstanding any information to the contrary in the agreement, or the terms of service, AWS provides the legacy version as is.
