The Apache Wicket PMC is proud to announce Apache Wicket 6.18.0!

This release marks another 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.

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

Upgrading from earlier versions

If you upgrade from 6.y.z 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

Have fun!
