Hi, Spring fans! In this installment I talk to Oracle VP and GraalVM founder Thomas Wuerthinger, recorded at Devoxx 2025!

On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 6.2.12 is available now.

Spring Framework 6.2.12 ships with 39 fixes and documentation improvements. This version will be shipped next week with Spring Boot 3.4.11 and 3.5.7.

Commercial customers using Spring Boot 2.7, 3.1, or 3.2 can make use of Spring Boot Hotfix releases 2.7.29.2, 3.2.18.2 and 3.3.15.2. Releases are available now on the Spring commercial artifact repository and can be accessed with a Spring Enterprise Subscription…

On behalf of the Spring Cloud and everyone who has contributed, I am pleased to announce that Spring Cloud Gateway 4.3.2, 4.2.5, 4.1.12, and 3.1.12 are out! In all cases, the releases are mostly composed of bug fixes, dependency upgrades.

Continuing our Road to GA series, this week we're exploring Share Groups in Apache Kafka 4.0.0 and their integration in Spring for Apache Kafka 4.0.0 - a feature that fundamentally expands how we can consume messages from Kafka topics.

When we first start working with Kafka, the mental model is straightforward: topics hold messages, consumers read them, and processing happens in order within partitions. This partition-based model has served countless applications well, providing ordered processing with strong guarantees. However, certain use cases involve creating topics with hundreds of…

It gives me great pleasure to announce that the Spring Session Hazelcast project will now be led by the Hazelcast Team.

NOTE: This announcement is in alignment with our announcement Spring Session MongoDB: Now Led by MongoDB Team.

For ten years Spring Session has provided the infrastructure for transparently replacing session stores in a vendor independent manner. With that infrastructure in place, it is just a matter of implementing SessionRepository javadoc in order to support storing session information in a new datastore.

I cannot think of a team who has more Hazelcast experience than the Hazelcast team themselves and so it gives me great pleasure to announce the Hazelcast team will be leading the next generation of Spring Session Hazelcast! To best enable this transition, the next generation of releases will be in a new GitHub repository and have new Maven coordinates. Support for existing generations of Spring Session Hazelcast will continue to be maintained by the Spring Session team as described by the Spring Support Policy…

It gives me great pleasure to announce that the Spring Session MongoDB project will now be led by the MongoDB Team.

I cannot think of a team who has more MongoDB experience than the MongoDB team themselves and so it gives me great pleasure to announce that the MongoDB team will be leading the next generation of Spring Session MongoDB! To best enable this transition, the next generation of code will be hosted in a new GitHub repository and have new Maven coordinates, both available in November. Support for existing generations of Spring Session MongoDB will continue to be maintained by the Spring Session team as described by the Spring Support Policy…

Hi, Spring fans! In this installment we talk to Spring Security contributor and legend Josh Cummings

I am pleased to announce that Spring Batch 6.0.0-M4 is now available from Maven Central!

The main changes in this milestone release are the following:

• Migration to nullability checks with jSpecify
• Improved domain model design

For the complete list of changes, please check the release notes here.

Null safety with JSpecify

Spring Batch 6.0 APIs are now annotated with JSpecify annotations to provide better null-safety guarantees and improve code quality. This change helps developers catch potential null-related issues at compile time, leading to more robust and reliable applications.

Improved…
