Java Spring Boot 3.0.0 RC1 Rocks Socks!

Phil Webb announced two days ago on the Spring blog that the much anticipated Spring Boot 3.0.0 RC1 is now available.

The release includes a whooping number of 135 improvements and features marking an important milestone for the most popular and cheered Java framework.

As we can read:

This release is the culmination of 11 months of work and is the first release to fully realize the themes that we set out to deliver in Spring Boot 3.0. Most notably, this release builds on the multi-year R&D effort that started with the experimental Spring Native project to provide support for GraalVM native images.
