We just released the sixth maintenance release of Hibernate ORM 5.4.
This release adds the ability to perform build-time bytecode enhancement as part of a Gradle build via a dedicated EnhanceTask. Previous versions simply leveraged a doLast hook on the standard JavaCompile task. This allows a chain of enhancers to be run or to enhance classes produced by means other than the standard Gradle JavaCompile task.
All details are available and up to date on the dedicated page on hibernate.org.
