+             <api name="general"/>
+             <summary>Added a way how to define UI component for non-leaf category node in project customizer</summary>
+             <version major="1" minor="22"/>
+             <date day="5" month="1" year="2007"/>
+             <author login="mkubec"/>
+             <compatibility addition="no" binary="compatible" deletion="no" deprecation="no" modification="yes" semantic="incompatible" source="compatible">
+                 Semantic change of handling files according to location and name on layer filesystem - File of particular filename 
+                 under category folder is handled differently.
+             </compatibility>
+             <description>
+                 Allow to define UI component for non-leaf category node in project customizer by setting name of the 
+                 file in folder on layer filesystem. If there is category Cat1 with some subcategories and 
+                 UI component is needed for Cat1, the folder that defines Cat1 in layer needs to contain file with name
+                 'Cat1.itself.instance'. Instance of the file will be used to create customizer component for the category.
+             </description>
+             <class package="org.netbeans.spi.project.ui.support" name="ProjectCustomizer"/>

          <change id="ProjectCustomizer.Category.buttonListener">
              <api name="general"/>
              <summary>Ability to attach a ok button listener on single customizer category.</summary>
