On behalf of the team and everyone who has contributed, I am pleased to announce a new milestone for the next Spring Framework generation. The fifth milestone continues delivering new features and refinements on top of 7.0.0-M1, 7.0.0-M2, 7.0.0-M3 and 7.0.0-M4.

Jackson 3.0 support

As of #33798, we default to supporting Jackson 3.x in our entire stack, falling back to Jackson 2.x. Support for the Jackson 2.x generation has been deprecated in Spring Framework, and our current plan is to disable its auto-detection in 7.1, and remove its support entirely in 7.2.

Jackson 3.x uses a new tools.jackson package, which differs from the usual com.fasterxml.jackson. Classes from the "jackson-annotation" artifact (like @JsonView, @JsonTypeInfo) remain in the com.fasterxml.jackson…

On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 6.1.20 and 6.2.7 are available now.

Spring Framework 6.1.20 ships with 4 fixes and documentation improvements. This version will be shipped next week with Spring Boot 3.3.12.

Spring Framework 6.2.7 ships with 25 fixes and documentation improvements. This version will be shipped next week with Spring Boot 3.4.6 and 3.5.0.

CVE-2025-22233:

The releases address CVE-2025-22233 for Spring Framework DataBinder Case Sensitive Match Exception (2nd update).

Open source support for Spring Framework 5.3.x and 6.0.x generations has ended and will expire for the 6.1.x generation next month, see our support page for more information…

Notable Changes in the 2025.0.0 Release Train

This release is based on Spring Boot 3.5.0-RC1.

For a complete list of changes made in this release see this project on GitHub.

Spring Cloud Config

• Support YAML specific profile documents in AWS S3 buckets (#2825)

Spring Cloud Gateway

• Support setting Spring.webflux.base-path and supporting it in path predicate (#2984)

• Support for reloading httpClient connectTimeout Configuration (#3679)
…

After reviewing our API design and deprecations post M7, we determined that several significant changes would become breaking changes in an RC1 release. Therefore, we've introduced this additional milestone to provide developers with a transitional release where deprecated APIs coexist alongside their replacements, enabling a smoother upgrade experience before RC1.

Here are the key changes in this release.
