## October 5, 2021

## What’s New

Mule 4.4.0 includes important enhancements and fixes.

### Enhancements

- Correlation ID Management

  Mule 4.4 enables you to modify the correlation ID associated with a Mule event. You can also
  change the algorithm Mule uses to generate each correlation ID.

  See [Correlation ID](https://docs.mulesoft.com/mule-runtime/latest/correlation-id) for additional information and
  configuration instructions.

- Improved Logging Capabilities

  Mule 4.4 incorporates the Mule Tracing module, which you can use to add, remove, and clear
  variables from the logging context for a given Mule event.

  See [MDC Logging](https://docs.mulesoft.com/mule-runtime/latest/logging-mdc) for additional information and
  configuration instructions.

- Feature Flagging Mechanism

  Mule 4.4 incorporates a feature flagging mechanism, which enables you to disable certain features
  that change core functionality in Mule to avoid backward compatibility issues.

  The following are the feature flags introduced in this release and its corresponding fixed issue
  ID:

  <table><colgroup><col> <col></colgroup><thead><tr><th>Feature Flag</th><th>Issue ID</th></tr></thead><tbody><tr><td><div><div><p><code>HONOUR_RESERVED_PROPERTIES_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-17659</code></p></div></div></td></tr><tr><td><div><div><p><code>HANDLE_SPLITTER_EXCEPTION_PROPERTY</code></p></div></div></td><td><div><div><p><code>DW-383</code></p></div></div></td></tr><tr><td><div><div><p><code>BATCH_FIXED_AGGREGATOR_TRANSACTION_RECORD_BUFFER_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19218</code></p></div></div></td></tr><tr><td><div><div><p><code>COMPUTE_CONNECTION_ERRORS_IN_STATS_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19020</code></p></div></div></td></tr><tr><td><div><div><p><code>TO_STRING_TRANSFORMER_TRANSFORM_ITERATOR_ELEMENTS_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19323</code></p></div></div></td></tr><tr><td><div><div><p><code>ENABLE_POLICY_ISOLATION_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19226</code></p></div></div></td></tr><tr><td><div><div><p><code>ENTITY_RESOLVER_FAIL_ON_FIRST_ERROR_PROPERTY</code></p></div></div></td><td><div><div><p><code>EE-7827</code></p></div></div></td></tr><tr><td><div><div><p><code>ENABLE_PROFILING_SERVICE_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19588</code></p></div></div></td></tr><tr><td><div><div><p><code>SET_VARIABLE_WITH_NULL_VALUE_PROPERTY</code></p></div></div></td><td><div><div><p><code>MULE-19443</code></p></div></div></td></tr></tbody></table>

  See [Feature Flagging](https://docs.mulesoft.com/mule-runtime/latest/feature-flagging) for a detailed description of
  each feature flag and configuration instructions.

## Upgrade

If you are upgrading to Mule 4.4 from an earlier Mule 4.x version, see
[Upgrading Mule Runtime Engine (Versions 4.x to 4.n)](https://docs.mulesoft.com/release-notes/mule-runtime/updating-mule-4-versions) for upgrade
instructions.

To ensure optimal performance with Mule 4.4 and avoid unexpected issues, update these modules and
extensions to their latest version at the time of this release:

<table><colgroup><col> <col></colgroup><thead><tr><th>Module or Extension</th><th>Version</th></tr></thead><tbody><tr><td><p>APIkit for Mule 4</p></td><td><p>1.5.5</p></td></tr><tr><td><p>APIkit for SOAP</p></td><td><p>1.2.9</p></td></tr><tr><td><p>Spring module</p></td><td><p>1.3.6</p></td></tr><tr><td><p>MUnit plugin</p></td><td><p>2.3.6</p></td></tr><tr><td><p>Module Testing Framework (mtf-tools)</p></td><td><p>1.1.1</p></td></tr></tbody></table>

### Considerations for Mule Extensions 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.
