This is an improvement in Wicket 7.0 which should not affect any application migrating from Wicket 6.x. But if you use Servlet 3.0's AsyncContext in IResource in Wicket 7 then make sure that your code flushes the http response after completing the request.

API changes

Changes to org.apache.wicket.ajax.json.*  Image AddedWICKET-6287 - Switch from json.org to open-json RESOLVED

Because of license issues all classes in the mentioned package have been replaced by classes of open-json (https://github.com/tdunning/open-json) which means that the basic functionality is nearly the same. Some classes however (example: org.json.HTTP) are throwing WicketRuntimeExceptions because there is no corresponding implementation in open-json, yet. json.org can be used in this case (can be found in the central maven repository) if the license conditions are accepted.

DecimalConverters' number format WICKET-5853 WICKET-5861

org.apache.wicket.util.convert.converter.AbstractDecimalConverter's #getNumberFormat() and #setNumberFormat() has been removed in favour of #newNumberFormat(). Applications using the old methods should override the new one, where they configure specifics or preserve a reference to the created NumberFormat.

org/apache/wicket/core/util/io/SerializableChecker is replaced with org.apache.wicket.core.util.objects.checker.CheckingObjectOutputStream WICKET-4817

...

Note: MountMapper and its related classes are still available in 7.x but deprecated and not used by Wicket itself. They will be completely removed in Wicket 8.0.0

Renamed all *AjaxResponse classes to *PartialPageUpdate WICKET-5929

XmlAjaxResponse was renamed to XmlPartialPageUpdate (see git commit 7c40e4dafa75973bf99b34567d977f310a5f02d0)
