On behalf of the team and everyone who contributed, I am pleased to announce the General Availability for Spring Integration 6.4.0 generation.

In addition the regular bug fixes and dependency upgrades were release as Spring Integration 6.3.6 and 6.2.11. The 6.2.11 is the last Open Source release. From now on updates to 6.2.x generation are going to be available via Commercial Support only.

Along side with bug fixes, dependency upgrades and internal improvements, here are some notable new feature in version 6.4:

• The new Control Bus interaction model is implemented in the ControlBusCommandRegistry.

A new ControlBusFactoryBean class is recommended to be used instead of deprecated ExpressionControlBusFactoryBean

• Also, a ControlBusController (together with an @EnableControlBusController) is introduced for managing exposed commands by the mentioned ControlBusCommandRegistry;
• The SpEL evaluation infrastructure now supports configuration for IndexAccessor;
• The outbound component ZeroMqMessageHandler (and respective API) can now bind a TCP port instead of connecting to a given URL.

Essentially, making it working as a server for the port folling regular ZeroMQ patterns;

• The DefaultSftpSessionFactory now exposes a Consumer<SshClient> configurer property to further customize an internal SshClient;
• The Python scripting support has been migrate to GraalVM Polyglot.

Now Python 3 language version can be used in your scripts. Plus all the benefits from third-party Python libraries;

• The RedisLockRegistry can now be configured with a TaskScheduler for automatic locks renewal in the store;
• The SourcePollingChannelAdapterSpec now can be configured with a custom TaskScheduler, e.g. for some TaskDecorator use-case;
• The @SpringIntegrationTest can now be used for test classes hierarchy, including @Nested configuration;
• The ZipTransformer now exposes a fileNameGenerator property to customize a target zip file (and optional zip entry) name generation;
• The BaseMessageBuilder has been extracted for easier custom MessageBuilderFactory implementation, e.g. when we would like to mask some sensitive information from message headers whenever the message is logged.

See What's New in 6.4 for more details.

Also a Migration Guide contains some breaking changes in this new version.

We are looking for any feedback on 6.4 to further improve the Framework and your experience for the next 6.5 generation planned in May 2025.

Cheers, 
Artem
