Apache Wicket 6.2.0 released

23 Oct 2012

The Apache Wicket PMC is proud to announce Apache Wicket 6.2.0!

This release marks the second minor release of Wicket 6. Starting with Wicket 6 we use semantic versioning for the future development of Wicket, and as such no API breaks are present in this release compared to 6.0.0.

New and noteworthy

SerializableChecker has been made easier to extend. It is now much easier to add your own checks at serialization time. For example, check whether your LoadableDetachableModels are detached, or no Hibernate entities are referenced directly from your component tree, etc.

For the full changelog see the release notes attached to the end of this announcement.

Using this release

With Apache Maven update your dependency to (and don’t forget to update any other dependencies on Wicket projects to the same version):


Or download and build the distribution yourself, or use our convenience binary package

Upgrading from earlier versions

If you upgrade from 6.0.0 or 6.1.0, this release is a drop in replacement. If you come from a version prior to 6.0.0, please read our Wicket 6 migration guide found at http://s.apache.org/wicket-6.0-migration

Have fun!
