Apache Wicket 10.0.0-M2 released

16 Oct 2023

The Apache Wicket PMC is proud to announce Apache Wicket 10.0.0-M2!

Apache Wicket is an open source Java component oriented web application framework that powers thousands of web applications and web sites for governments, stores, universities, cities, banks, email providers, and more. You can find more about Apache Wicket at https://wicket.apache.org

This release marks another minor release of Wicket 10. We use semantic versioning for the development of Wicket, and as such no API breaks are present in this release compared to 10.0.0.

New and noteworthy

In order to improve JPMS adoption, this release introduces the new module wicket-tester containing common classes for unit testing. Users of class WicketTester must now include this module as test dependency.

Or download and build the distribution yourself, or use our convenience binary package you can find here:
