Summary
Spring Boot 4.2.0-M1 adds generic AMQP 1.0 and RabbitMQ AMQP 1.0 support, and lets Cloud Native Buildpacks publish and restore build caches through an image registry. Its release notes also change forwarded-header configuration and stop test MeterRegistry beans entering Micrometer’s global registry by default.
Why it matters
