What’s New
The 4.6.0 version of Mule runtime introduces the following enhancements:
Java adoption:
-
MuleSoft is adopting Java’s long-term support (LTS) release cadence, beginning with Mule runtime 4.6, which adds support for Java 17 LTS. See Java Adoption.
The maximum supported version for running your applications is Java 17 for Mule runtime 4.6.x and later. During the packaging of your app, all code, including third-party dependencies, must be compiled for Java 8. -
Java 17 manages memory differently than Java 8. See Application Performance.
-
Mule runtime classes are now modularized per the Java module system introduced back in Java 9 (also known as JPMS or Project Jigsaw). Reflective introspection of Mule runtime classes is now limited. To maintain backward compatibility, reflective access to classes defined within the scope of your applications and domains remains open to access.
-
Java EE libraries are now removed from Mule runtime for Java 17.
Mule Gateway improvements:
-
You can now upgrade your policies and API proxies to Java 17. See Upgrading Policies and Upgrading API Proxies.
-
Mule Gateway now supports API analytics event logging. To enable event logging, see Log Analytics Event Data.
-
Mule Gateway now supports automatically deleting cached policy files. To enable this feature, see Cached Policy Assets Deletion.
Mule SDK improvements:
-
Mule SDK (Java SDK and XML SDK) now support Java 17. See Upgrading Custom Connectors.
-
Java SDK now includes the new
@JavaVersionSupport
annotation. See Supported Java Version Concept. -
XML SDK now supports TLS. See XML SDK TLS Support.
General improvements:
-
The Joda-Time library is upgraded to version 2.12.5.
-
The GraalJS library is upgraded to 22.3.3.
DataWeave Features
The 2.6.0 version of DataWeave introduces the following new features and enhancements:
Extended format support:
-
DataWeave now supports Java 17. See Java Format.
-
Mule expression language service are now modularized.

Upgrade
If you are upgrading to this version of Mule from an earlier Mule 4.x version, see Mule Upgrades and Patch Updates.
To ensure optimal performance with this version of Mule and avoid unexpected issues, update the following modules and extensions to their latest version at the time of this release:
Module or Extension | Version |
---|---|
APIkit for Mule 4 |
1.10.1 |
APIkit for OData |
2.2.1 |
APIkit for OData 4 |
1.3.4 |
APIkit for SOAP |
1.4.1 |

Considerations for Mule Extension Developers
If you update the version of your parent pom.xml
file to 1.4.0 or later when you build a Mule extension, ensure that the dependencies in your pom.xml
file do not override dependencies defined in the parent pom.xml
file, and declare only the dependencies you need. If you need to declare a dependency that is already declared in the parent pom.xml
file, do not specify a version so it uses the version from the parent pom.xml
file.
