Apache Wicket 6.1.0 released

04 Oct 2012

The Apache Wicket PMC is proud to announce Apache Wicket 6.1.0!

This release marks the first maintenance 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

Wicket CDI has been integrated as a core module, and can be used to manage conversations in your Wicket application with ease.

Wicket Experimental:

  • Wicket Bootstrap has been upgraded to 2.1.1
  • Several issues with Wicket Atmosphere have been resolved

Known issues

This release has two known issues, which will be solved shortly in 6.1.1 and 6.2.0:

  • WICKET-4789 The way URLs are encoded was changed (WICKET-4645) and now the first request (with ;jsessionid in path) generates invalid internal links.
  • WICKET-4759 FilterForm/FilterToolbar don’t work when there’s more than one IColumn to be filtered

Any other issues will be released in 6.2.0

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, 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!
