THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
Wicket-Guice's InjectionFlagCachingGuiceComponentInjector is removed. The replacement is GuiceComponentInjector. The caching mechanism that InjectionFlagCachingGuiceComponentInjector provided is moved to org.apache.wicket.injection.Injector so that the caching is re-used for both Wicket-Spring and Wicket-Guice.
Visitors
Visitors have been cleaned up. Dependency on magic return values defined in Component#IVisitor have been replaced with a Component#IVisit object that allows the visitor to control the flow of the traversal.

\[1] The new style visitor no longer returns a value, instead the value can be returned using visit.stop(value)
\[2] The new visit object is introduced to control the visitor traversal
\[3] Instead of relying on magic return values the traversal is stopped by using the new visit object
\[4] Same as \[3] but a different method on IVisit is used |
