Apache Wicket 7.4.0 released

21 Jul 2016

The Apache Wicket PMC is proud to announce Apache Wicket 7.4.0!

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 7. We use semantic versioning for the development of Wicket, and as such no API breaks are present breaks are present in this release compared to 7.0.0.

New and noteworthy

  • improves stateless AJAX support by integrating the Wicket Stuff wicket-stateless module (WICKET-6183)

  • improves compatibility for playing videos on iOS devices due to missing media type in MediaComponent

  • upgrades provided JQuery to 1.12.4 and 2.2.4

  • improves compatibility with CGLIB when using wicket-jmx
