Quarkus 3.35 - @Transactional for Hibernate Reactive, PGO for native, JAR tree-shaking, and more

Quarkus 3.35 has been released with several notable features. JAR tree-shaking (experimental) uses bytecode reachability analysis to eliminate unused classes, reducing JAR size by up to 39.5% in testing. Profile-Guided Optimization (PGO) is now available for native builds via Oracle GraalVM, using integration tests as profiling workloads. IBM Semeru AOT support is added, cutting startup times roughly in half in initial tests. The @Transactional annotation is now supported for Hibernate Reactive via a new quarkus-reactive-transactions extension, managing transaction lifecycle within reactive pipelines. Additional improvements include dedicated CORS configuration for the management interface, testing infrastructure changes that remove System Properties for config propagation, and a new snapshot distribution via GitHub Releases instead of Sonatype.
