Current Release Version

Mule 3.1 Improvements

The biggest enhancements in Mule 3.1 are the new features for Mule Cloud-Connect. It is now very simple to, for instance:

• Invoke a cloud service
• Use the data it returns to invoke other services
• Combine the data returned by all of these services
• Use the result to invoke yet another service (or write it to a database, or persist it as XML, or format it as a web page, or...There's really no limit but your imagination.)

Migration from Previous Versions

For instructions on migrating from a previous version, consult the Mule Migration page.

Invocation Improvements

The three main innovations here are

• <strong>invoke</strong>, which makes calling a cloud service a snap.
• <strong>poll</strong>, which makes it easy to poll a service for incoming data.
• <strong>enricher</strong>, which lets you combine data from many different calls into one rich message.

Improvements to Logging

In addition, Mule configurations now support a simple yet powerful logging facility, which provides access to log4J levels and categories together with the full range of Mule expressions. For instance,

• CXF 2.3.0 support includes WS-Addressing, WS-Reliable Messaging, and WS-Secure Conversation

Major Improvements

• MULE-4689 - The crytpix libs used by the PGP module replace with bouncycastle
• MULE-4774 - EndpointMessageNotification now provided for response messages of synchronous transports
• MULE-5110 - Defining attribute "processEngine-ref" of connector "jbpm-connector" as IDREF in mule-bpm.xsd is now less restrictive
• MULE-5114 - JBPM 4.4 now supported
• MULE-5152 - MULE_HOME no longer needs to be set before starting Mule
• MULE-5204 - Hibernate version 3.6.0 now supported
• MULE-5224 - Generates warnings for deprecated schema elements
• MULE-5228 - Variable expression evaluator/enricher for temporary storage during flow
• MULE-5248 - JCA packaging from CE removed
