Dear Spring community,
It is my pleasure to announce that the first Spring Framework 6.0 milestone release is available from htts://repo.spring.io/milestone now. This initial milestone covers our baseline upgrade efforts, in particular requiring JDK 17+ and migrating to the Jakarta EE 9 APIs; see my recent baseline blog post for the rationale. At the same time, it removes many long-deprecated classes, including several support packages for outdated third-party infrastructure.
For current upgrade notes, please refer to our Upgrading to Spring Framework 6.0 page which we will keep updating. Follow our main branch on GitHub for the latest changes, as we prepare for 6.0 M2 and the corresponding Spring Boot 3.0 M1 release in January. At that point, you will also be able to consume Spring Framework 6.0 through https://start.spring.io/. For the time being, feel free to grab 6.0 M1 from https://repo.spring.io/ and let us know how it goes.
