Dear Spring community,

On behalf the team and everybody contributed, it’s my pleasure to announce that last week we released general availability for Spring Integration 5.4.

It can be downloaded from Maven Central:

compile 'org.springframework.integration:spring-integration-core:5.4.0'

Here is a summary of features and improvements for this Spring Integration generation:

• R2DBC channel adapters;

• ZeroMQ proxy, message channel and channel adapters;

• Redis Streams channel adapters (which are reactive);

• The spring-integration-kafka extension has been moved to the core project and, alongside with an upgrade to the latest Spring for Apache Kafka 2.6.2, includes some improvements;

• The RenewableLockRegistry is implemented for the JdbcLockRegistry.

See What’s New in documentation for more information.

This version is included into dependency management of Spring Boot 2.4.0-RC1.
