On the road to Spring Data 2022.0.0 and 2021.2.0, the first milestone releases have been made available. Version 2022.0.0-M1, codenamed Turing, is the first release in the Spring Data 3.0 release train featuring migration to the Jakarta EE 9 APIs and will require JDK 17+. Version 2021.2.0, codenamed Raj, features dependency upgrades and direct projections for Spring Data MongoDB, Spring Data for Cassandra, and Spring Data Neo4j.
