-6.6 brings many new features, in addition to many improvements and fixes.
+Hibernate 6.6 includes a complete implementation of the current Jakarta Data 1.0 Release Candidate. As [discussed here](https://in.relation.to/2024/04/18/jakarta-data-1/), our implementation:
+
+- is based on compile-time code generation via an annotation processor, enabling unprecedented compile-time type safety, and
+- is backed by Hibernate's `StatelessSession`, which has been enhanced especially to meet the needs of Jakarta Data.
+
+This implementation already passes the Jakarta Data TCK, and we have a request for certification pending.
+
+To make use of _Hibernate Data Repositories_, you'll need to depend on:
+
+- our annotation processor, `hibernate-jpamodelgen`, and
+- the Jakarta Data API, `jakarta.data-api.
+
+For example, in Gradle:
+
+[source,groovy]
+----
+implementation 'jakarta.data:jakarta.data-api:1.0.0-RC1'
+implementation 'org.hibernate.orm:hibernate-core:6.6.0.Alpha1'
+
+annotationProcessor 'org.hibernate.orm:hibernate-jpamodelgen:6.6.0.Alpha1'
+----
