Hibernate ORM Roadmap
Hibernate ORM Roadmap
Hibernate ORM is community driven! Therefore, the roadmap is extremely fluid and evolves frequently. The most detailed and up-to-date roadmap is consists of the issues and planned release versions in JIRA: issue tracker. However, the following is a decent view of where we’re headed.
