Hibernate is a powerful, high performance object/relational persistence and query service. Hibernate lets you develop persistent classes following object-oriented idiom - including association, inheritance, polymorphism, composition, and collections. Hibernate allows you to express queries in its own portable SQL extension (HQL), as well as in native SQL, or with an object-oriented Criteria and Example API.

Hibernate 3.1.2 has been released with new features and promises on Jan 17, 2006. This maintenance release focused on bug fixes and improvements, especially regarding:

This release fixes, amongst other minor bugs/enhancements:
    * bugs with Session closure checking
    * some potential bugs in HQL parameter binding - especially mixing named and ordinal parameters
    * issues with "borrowed connections" (i.e. Session.connection()) with aggressive connection releasing.

Changes:
