Quarkus 4.0.0.Beta1 is tagged! Java 21 becomes the minimum, with Jackson 3, Hibernate ORM 8, Jakarta REST 4, and CDI 5 among the changes. A good time to test a familiar application against the beta and report any rough edges. I’d start with JSON serialization and persistence tests. Thanks to everyone building and testing this release. https://github.com/quarkusio/quarkus/releases/tag/4.0.0.Beta1
