Apache Wicket 6.3.0 released

16 Nov 2012

The Apache Wicket PMC is proud to announce Apache Wicket 6.3.0!

This release marks the third 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

This release fixes some javascript errors in IE7 and IE8 with Wicket 6.

We have upgraded the embedded JQuery library to 1.8.2 (the most recent stable release of JQuery). If you depend on an earlier version of JQuery, you can instruct Wicket to use your older version. See the Wicket Ajax Guide for more information.

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, 6.1.0, or 6.2.0 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!
