+## Release Highlights
+
+- **Audit Logging (Enterprise) :** Consul on ECS now captures authentication events and processes them with the HTTP API. Audit logging provides insight into access and usage patterns. Refer to [Audit Logging](/docs/ecs/enterprise#audit-logging) for usage information.
+
+- **AWS IAM Auth Method :** This feature provides support for Consul's AWS IAM auth method. This allows AWS IAM roles and users to authenticate with Consul to obtain ACL tokens. Refer to [ECS Configuration Reference](/docs/ecs/configuration-reference#consullogin) for configuration information.
+
+- **Mesh Gateways :** This feature introduces support for running mesh gateways as ECS tasks. Mesh gateways enable service mesh communication across datacenter and admin partition boundaries. Refer to [ECS Installation with Terraform](/docs/ecs/terraform/install#configure-the-gateway-task-module) for usage information.
