05 February 2008 - Apache Cayenne 3.0M3 Now Available

The Apache Cayenne team is pleased to present the third milestone of Cayenne 3. This is a development branch of Cayenne and still undergoing significant changes. A number of developers are using it in production systems, however if you want the most stable and tested version of Cayenne you should use version 1.x or 2.x which have a proven track record and are widely used in deployment.

This milestone release adds some exciting new features, including enhancements to the Cayenne modeler for lifecycle listeners and callbacks and the ability to merge changes to the model back to the database, extensive new work toward full JPA compliance, updates to cgen and the templates, and much more.

This release requires Java 5 as a minimum. The decision to change the required JDK was made after a poll of users revealed no substantial need for Java 1.4 and plenty of benefits in moving forward. Generics are only partially completed in the public API at this time and we continue to try and balance the opportunities and headaches of a clean generics interface.

Cayenne is a powerful, full-featured, opensource framework created for developers working with relational databases. it seamlessly maps any relational database to Java objects, reducing development time and adding considerable functionality to any application which requires a database. Developers using Cayenne will be able to concentrate on the core business requirements and the data model instead of the SQL details. The application can then be easily moved to any JDBC-capable database. In addition to management of persistent Java objects mapped to relational databases, Cayenne provides a plethora of features including single method call queries and updates (including atomic updates of all modified objects), seamless integration of multiple databases into a single virtual data source, three tier persistence with caching on the remote client, paging of results, record locking, and many more features. JPA compliance is in progress.
