 Currently (October 2025) module is **NOT supported for Jackson 3.x** due to lack of active maintainer.
 It is considered Deprecated as part of [JSTEP-9](https://github.com/FasterXML/jackson-future-ideas/wiki/JSTEP-9).
 
-Note: Hibernate 4.x, 5.x, 6.x and 7.x are supported (5.x starting with Jackson 2.6; 6.x with Jackson 2.15 and 7.x with Jackson 2.20) but they require different jars, and Maven artifact names (and jar names differ).

 This document refers to "Hibernate 5" version, but changes with 4.x/6.x/7.x should require
 little more than replacing "5" in names with "4", "6" or "7".

 ### JDK requirements
 
-Before Jackson 2.15, baseline JDK needed for building for JDK 8 and all
-module variants worked on Java 8.
-
-With Jackson 2.15, JDK 11 will be required to build: all modules run on
-Java 8 except for Hibernate 6.x module which requires Java 11 like
-Hibernate 6.x itself.
-
-With Jackson 2.20, JDK 17 will be required to build: 4.x and 5.x modules run on
-Java 8, 6.x on 11 and Hibernate 7.x module requires Java 17 like
-Hibernate 7.x itself.
+Java 17 or above is required.
