Efficient Error Handling: Mule 4 streamlines error handling by categorizing errors during the design phase, reducing the need to comb through extensive code to locate issues. It also allows for well-defined error handling blocks, improving error management with details like error descriptions, types, causes, and clear error messages.

Streamlined Error Event Processing: Mule 4 introduces the “Try” scope, eliminating the need for separate error flows and optimizing error handling time and costs. This enhances default error handling, increasing error visibility, and offering more control over error management.

Better configurability with Maven: Mule 4 seamlessly integrates with Maven, making all applications Maven-ready by default. This simplifies application development and management.

Simplified Event Processing: Mule 4 streamlines event processing by merging inbound and outbound properties under the “Attributes” category. It also offers improved payload handling and data transformation.
