On behalf of the community, I am excited to announce the availability of Spring Modulith 2.1 M2, 2.0.4, and 1.4.8. The bug fix releases primarily ship the usual dependency upgrades. Besides the usual platform upgrades (Spring Boot 2.1 M2), the second milestone of the 2.1 release is packed with new features:

• Support for an outbox-based event externalization – As an alternative to the built-in, asynchronous, event-listener-based externalization, we now support the externalization through Namastack Outbox, supporting multi-instance, order-preserving publication. Find an example here. Big thanks to Roland Beisel, the lead of Namastack Outbox, for the contribution! #1517

• The ability to run an application module integration test is now combinable with Spring Boot's horizontal slice test capabilities. #1573

• The events captured in PublishedEvents and Scenario are bound from the entire application (previously thread-bound). This enables tests to see events from independent thread pools, such as the one used by the outbox integration mentioned above. #1564

1.4.2 ships with more detailed application module metadata generated into application-modules.json (either with our AOT support enabled during the build or via the documentation generated through the Documenter API). This has enabled our friends at Sonargraph, a tool to logically define application architectures and perform advanced exploration and verification, to build integration for Spring Modulith applications. As described in their announcing blog post, they now support creating an architecture definition by picking up the structure defined in you application…
