The Apache Wicket team is proud to announce the availability of the fourth maintenance release: Apache Wicket 1.3.4. A lot of bugs have been squashed and several improvements implemented. Two noteworthy bugs have been squashed:

  • cross session leakage due to a dangling thread local in exceptional circumstances
  • memory leak in localizer (WICKET-1667)

It is therefore recommended you update to Wicket 1.3.4 at your earliest convenience.

Apache Wicket

Apache Wicket is a component oriented Java web application framework. With proper mark-up/logic separation, a POJO data model, and a refreshing lack of XML, Apache Wicket makes developing web-apps simple and enjoyable again. Swap the boilerplate, complex debugging and brittle code for powerful, reusable components written with plain Java and HTML.

You can find out more about Apache Wicket on our website:
