Didn’t have much time for writing lately. Still felt the topic of Apache Cayenne 4.0 is important enough to say a few words, even though this is coming to you months after the final release. So here is a belated overview of the release scope and its significance. Enjoy!
As you may know, Cayenne is a Java ORM, i.e. an intermediary between your Java objects and the database, that keeps object and relational worlds in sync and lets you run queries and persist data. The current stable version of Cayenne is 4.0 and it was released in August 2018.
