On behalf of the team and everyone who contributed, I am pleased to announce the Third Milestone of Spring Integration 7.0.0 generation. For convenience, the 7.0.0-M3 artifacts are also available in Maven Central.

In addition, the 6.5.2 and 6.4.7 versions with bug fixes and dependency upgrades have been released.

Some notable changes in 7.0.0-M3 are:

• JUnit 6 upgrade;
• The Nullability via JSpecify and Nullaway is applied to every single package in the project;
• The AbstractPersistentAcceptOnceFileListFilter implementations now deal with full remote file to avoid conflict with the same file name in different directories;
• The AbstractInboundFileSynchronizer now caches the Session.list() result (after filtering) between polls when maxFetchSize is limited;
• The Spring Retry dependnecy has been removed and its API has been replaced with similar one in the Spring Framework Core;
• All the available major/minor dependency upgrades.

See What's New in 7.0 for more details.

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

We are heading now to code freeze in Release Candidate 1 in October. Don't hesitate to reach us out in GitHub issues for the project with any feedback!

Cheers, 
Artem
