The following features and improvements were introduced with WSO2 Micro Integrator 4.4.0.
Enhanced VS Code User Interface
The VS Code-based user interface has been optimized for a more intuitive and efficient developer experience.
Simplified Setup and Onboarding
WSO2 Micro Integrator 4.4.0 simplifies setup and onboarding by enabling direct installation via the VS Code plugin. Users are automatically prompted to download Java and WSO2 Micro Integrator, while the system configures the Maven Wrapper and JAVA_HOME—eliminating manual configurations and expediting a seamless setup.
Simplified Expressions
A new expression system with an innovative expression editor and simplified syntax reduces the complexity of creating, testing, and debugging expressions. This enhancement makes expression management more intuitive for both new and experienced users. See the Synapse Expressions documentation for more information.
Simplified Connector Creation
A new tool auto-generates connectors using OpenAPI specifications directly within the VS Code extension. This feature streamlines connector development, enabling faster integration without the usual manual overhead.
Enhanced Mediator Testing Capabilities
The new "Trying Out Mediator" feature introduces an interactive testing environment. Developers can now input test payloads at the start node of their integration flow, observing mediator behavior from both diagram and form views in real-time significantly reducing iteration time. See the Try-out Feature documentation for more information.
New Mediators, Connectors, and UI Enhancements
New Scatter-Gather, ForEach, and Variable mediators have been added to address common integration scenarios. In addition, the mediator UI has been simplified for improved usability, and a new HTTP connector has been introduced to ease integration with HTTP/S systems.
