 Currently, our MQ emulation offers only fundamental capabilities, and it comes with certain limitations:
 
-- **ActiveMQ Version Limitation:** Presently, only ActiveMQ version 5.16.6 is supported.
+- **ActiveMQ Version Limitation:** LocalStack pins Apache MQ 5.18 to the patched version 5.18.7.
+Since June 2025, [5.18 is the only supported version on AWS](https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/activemq-version-management.html).
   RabbitMQ is not supported at this time.
 - **IAM User Management:** IAM Users are not actively enforced, although they are necessary for making correct calls within the system.
 - **Configuration Enforcement:** While it is feasible to create configurations, they are not actively enforced within the broker.
