Minimum Java version is now 1.5.

Spring Support

The biggest API break is to the getModel() method. In 1.3, Component had a method getModel() that returned the model object of the default model of the component. This was renamed to getDefaultModel(), as well as it's supporting methods (i.e. getDefaultModelObject() and getDefaultModelObjectAsString()). This method returns IModel<?>. This change was made as part of the 1.4-M3 release. In the M1 and M2 releases, getModel() returned IModel<T> because Component had the generic type T. In M3 and subsequent releases, only certain components (including FormComponent and all subclasses, as well as Link and several other core components) were genericized. This included defining them as ComponentName<T> and including a getModel() method that returned IModel<T>.

If you are migrating from 1.3 to 1.4, simply replace getModel() calls with getDefaultModel() wherever your compiler indicates an error for this change.
