Happy now to announce a successful release of Hibernate ORM 5.5.4.Final! It is already available for download from your favourite Maven Central mirror.

Physical Naming Strategy

A new CamelCaseToUnderscoresNamingStrategy has been introduced (see HHH-14728), the new strategy is the equivalent of the Spring SpringPhysicalNamingStrategy.

The CamelCaseToUnderscoresNamingStrategy replaces all dots with underscores, all camel casing with underscores and generates all table names in lower case.

For example, the LineItem entity will be mapped to the line_item table.


Hibernate can now get IdentifierGenerator definitions from BeanContainer when not registered (see HHH-14688).

Java 18

We are running tests with an early version of JDK 18 and all tests are green.


Some other defects have been fixed, for a full list see the Release Notes.
