0.6.0

Released on October 14, 2025 With this release the ECS worker now uses an event-based architecture that receives task state changes via EventBridge and SQS, replacing the previous polling-based design. This dramatically improves crash detection responsiveness and reduces API overhead. The worker gracefully degrades to limited functionality if SQS is unavailable, ensuring continued operation even during infrastructure issues. See the ECS worker documentation for setup instructions. Features

• Move ECS worker to event-based crash detection #18804 by @desertaxle

​

0.5.14

Released on August 26, 2025 This release introduces significant improvements to ECS worker management and observability. The new prefect-aws CLI simplifies ECS worker deployment with commands to deploy and manage ECS workers using CloudFormation templates. Additionally, event replication capabilities have been added to the ECS worker, enabling real-time monitoring of ECS task state changes through SQS and EventBridge. This creates a foundation for more stateless ECS worker operations and ensures events aren’t lost if workers go down during flow execution. See the ECS worker documentation for CLI usage examples and deployment guides. Features

• Add prefect-aws Docker images #18750 by @desertaxle
• Add CDK stacks for ECS worker infrastructure #18755 by @desertaxle
