Dear Spring community,

On behalf the team and external contributors, it’s my pleasure to announce a Milestone 3 release for Spring Integration 5.5, plus Spring Integration 5.4.5 patch version.

The latest one can be downloaded from Maven Central:

compile 'org.springframework.integration:spring-integration-core:5.4.5'

and it is recommended to upgrade your projects or just pull it transitively from just released Spring Boot 2.4.4!

The Milestone is available from the https://repo.spring.io/milestone/ repository:

compile 'org.springframework.integration:spring-integration-core:5.5.0-M3'

The 5.5 generation of Spring Integration is the last one in the line before we start 6.0 and it is mostly based on the community feedback and usability needs. For example we have reworked some warning messages in logs to the fail-fast errors during configuration phase. Plus some API was deprecated with possible removal in the next major version. So, be sure check the Migration Guide…
