| Child flows of Serverless Workflow | To reduce flow complexity, a flow is divided into multiple child flows. Flows can be reused more easily. You can put some common steps in a flow and reuse these steps in other flows. This feature breaks some limits of a flow, such as the maximum number of events (5,000 by default) and the maximum execution time (1 year). Error handling is implemented for the overall output of the flow. For example, you can design a parallel step as a child flow and handle errors that occur in the execution of the child flows in the parent flow. | 2020-02-29 | Child flows of Serverless Workflow |

| Support for calling functions by version and alias | You can call a version-specific function in a flow to update the function without affecting the flow execution. You can also call functions by alias in a flow and use the alias feature of Function Compute to perform phased tests on the functions and use functions with reserved resources. | 2019-11-13 | Schedule reserved resource functions or functions with specified versions |
| Availability in China (Beijing) | Serverless Workflow became available in China (Beijing). You can use Serverless Workflow to orchestrate functions and distributed tasks in China (Hangzhou), China (Shanghai), China (Shenzhen), and China (Beijing). | 2019-11-01 | None |
| Integration of Message Service and support for callback | This feature enables Serverless Workflow to coordinate distributed applications that are running on different architectures, networks, and languages. Serverless Workflow serves as a coordinator when applications transit from Apsara Stack to the hybrid cloud (Apsara Stack and Alibaba Cloud) or Alibaba Cloud or evolve from a monolithic architecture to a microservices architecture. By integrating Message Service (MNS) queues, Serverless Workflow allows all applications that can access message queues to be part of a flow and cooperate to achieve business objectives. | 2019-11-01 | Integrate MNS and use callback to orchestrate any type of tasks |
