Releasing Spring For Modern Challenges TL;DR: The Spring release train has been updated from a two week long train to a single day, the Thursday after the third Monday of the month. The next regular patch train will be on October 22nd. A milestone only train will occur on September 24th. Back in June, we wrote to you all about how AI has changed the rate in which new vulnerabilities are being found and exploited in the wild. That has not slowed down. We have averaged nearly 80 new community provided security reports a month since March, in addition to our own internal scanning with frontier…
TL;DR: As previously mentioned, the May Spring release train has been moved and condensed to June 8-14. The majority of projects within the Spring portfolio will require upgrades for newly released security patches. It is strongly recommended to upgrade as soon as possible to the latest patches. Details about the expected scheduling is available at calendar.spring.io. Everywhere one looks in 2026, generative AI dominates the news. Across our industry, we are seeing material impacts of generative AI and its ability to accelerate time to market for business capabilities, improve quality by…
UPDATE: The Spring release train needs to move one more time to June 8-12. Updates to https://calendar.spring.io are forthcoming. We thank you for your understanding and patience. In preparation for the May release train which will include updates across the portfolio and new minor versions (Spring Boot 4.1, etc) we are shifting the release train from the originally scheduled timeline from May 11-22 to the new timeline of June 1-5. This applies to all OSS versions including new minor releases and patch releases. https://calendar.spring.io will be updated soon in accordance with this. We look…
As you all should be aware by now, the Spring portfolio is in the process of driving towards the next major versions to be released in November of this year. This will be only the fourth major generation for Spring Boot and the seventh major generation for Spring Framework in its over 20 year history. We are excited to bring you a great set of new features that builds on the current foundations. While we are keeping the JDK baseline at JDK 17 because that is the industry consensus, we will upgrade to Jakarta EE 11 (Tomcat 11, Hibernate ORM 7, Hibernate Validator 9) and embrace other upgrades…
Spring Cloud Data Flow End of Open-Source TL;DR; Today we're announcing that going forward we will not be maintaining Spring Cloud Data Flow, Spring Cloud Deployer, or Spring Statemachine as open-source projects. Spring Cloud Data Flow 2.11.x, Spring Cloud Deployer 2.9.x, and Spring Statemachine 4.0.x will be the last open-source lines and any future releases will only be made available to Tanzu Spring customers. This change has no impact on the rest of the open-source Spring portfolio or the support obligations of the currently available OSS versions for existing users. Spring Cloud Data Flow…
TL;DR; The Spring portfolio enterprise support tier is aligning all support dates to Spring Boot and going to be extended for the last minor version of each major generation for an additional 5 years beyond the previous support arrangement providing 7 years of total support for those versions. Upgrading is hard. We get that. Whether it be technical difficulties, prioritization of upgrades against other business priorities, “if it ain’t broke, don’t fix it”, etc. While we already offer one of the most generous and predictable support policies in the industry for open source frameworks with one…
TL;DR; The Spring portfolio will begin releasing its milestones and release candidates to Maven Central starting with the releases related to the major versions due out in November. As we enter the new year, we look forward to many new opportunities for the Spring ecosystem. We see JDK 25 coming in the fall. We see both minor versions of the entire portfolio and a new major version coming out this year with a long list of new capabilities. And we see Spring AI going GA ushering in a new class of workloads for enterprise applications, bringing agentic AI to the enterprise through programming…

New Capabilities Abound Below is just a small sampling of the new and exciting capabilities included in the November releases of the Spring portfolio. We encourage you to check out the release notes for your favorite projects for further…
Upgrading takes time. We understand that. Spring Boot 3 came out in November of 2022 bringing with it a new, modernized baseline of Java 17 and the migration from Java EE to Jakarta EE. It included over 55 managed dependency updates. Native compilation via GraalVM was a first-class option across the portfolio and observability out of the box was a core capability of all Spring projects. However, it wasn't until Spring Boot 3.2 where we began to see that the community's adoption of Spring Boot 3 surpassing that of Spring Boot 2's adoption. Spring Boot 3 has quickly overtaken Spring Boot 2 but…
