After half a year of development, Spring Modulith 1.3 GA has been released). It is packed with new features, improvements, and – best of all – community contributions. Let me walk you through some of the most interesting ones.

Baseline Upgrades

As usual, a new minor version of Spring Modulith upgrades to the latest releases of both Spring Boot and Spring Framework, 3.4 and 6.2 respectively. That said, we still remain compatible with the previous generations of each of them so that you can selectively upgrade to Spring Modulith 1.3 without having to the latest Boot and Framework versions.

On behalf of the community, I am delighted to announce the avability of Spring Modulith 1.3 RC1, 1.2.5, and 1.1.10. While the service releases contain a few bugfixes and the usual dependency updates, the release candidate is packed with features and improvements such as (full change log here):

• An archiving event publication completion mode (thanks to Cora Iberkleid for the contribution).
• Support for MariaDB (thanks, @Fezlight) and Oracle DB (thanks to @DSXVII) in the JDBC-based event publication registry.
• Support to externalize events into a Spring (Integration) MessageChannel via the new spring-modulith-events-messaging artifact (thanks to Josh Long for the contribution).
• Event externalization now allows to add headers to the messages sent out and uses the Spring Message abstraction for broker interaction where feasible.
• Support for SpEL expressions in @Externalized.
• Deprecate event externalization for Amazon SQS and SNS in favor of the implementation in Spring Cloud AWS (thanks to Marcin Slowiak…

I am happy to announce the availability of Spring Modulith 1.3 M3, 1.2.4, and 1.1.9. While the latter two ship the usual bugfixes and service release bugfix upgrades, I am particularly delighted about the milestone releases as it contains two major community contributions. Here are the most significant new features:

• Support for change-aware test execution (contributed by @lukasdo and @davidbilge) which optimizes test runs along the changes made to the application by skipping tests not affected by those.
• A new deleting event publication completion mode to — as the name suggests — immediately delete completed event publications.
• Support for contributing application modules from other packages and external JARs.
• Support for Microsoft SQL Server in JDBC-based event publication registry (contributed by @oyjoh, GH-804).
• Deprecate spring.modulith.republish-outstanding-events-on-restart in favor of the variant residing in spring.modulith.test.… (GH-823…

It is my pleasure to announce the availability of Spring Modulith 1.3 M2, 1.2.3, and 1.1.8. They all contain bug fixes and upgrades to the latest versions of dependencies. Here are the most important features of the releases:

• Support for nested application modules (1.3 M2 only). See the reference documentation for details. – GH-578
• Event publication completion now issues a by-id query to significantly improve performance and reduce load on the database (1.3 M2 only). – GH-258
• Minor performance improvements for event completion (all releases). – GH-749

For details, please check out the change logs for 1.3 M2, 1.2.3, and 1.1.8. We appreciate any kind of feedback, in particular regarding the milestone release, in the GitHub discussions…

I am excited to announce the releases of Spring Modulith 1.3 M1, 1.2.2, and 1.1.7. The former ships with the following new features:

I am delighted to announce the availability of Spring Modulith 1.1.6 and 1.2.1. The releases contain a few bug fixes, minor new features and the usual dependency upgrades. The highlights are the following:

I am excited to announce the availability of Spring Modulith 1.2 alongside the service releases 1.1.5 and 1.0.8. The latter two contain a lot of bug fixes, improvements and dependency upgrades. 1.2 most notably ships with new features:

• Support for open application modules
• Support for a package-info.java alternative for Kotlin

I am happy to announce the release of Spring Modulith 1.0.7 and 1.1.4. it primarily ships an upgrade to ArchUnit 1.1.1 which in turn includes a fix to now support the new fat JAR format of Spring Boot. It had been improved in 3.2 but unfortunately broke ArchUnit's class scanning. Spring Modulith applications that were using the runtime, actuator and observability modules had been affected and should now properly work.
