       * Feature: MusE now has two mixers, with selectable track type display. (T356)
         - Changes to .med file were needed. Tested OK so far with old and new song files.
+      * Fixed: Builtin freeverb and TAP reverb ladspa GUIs, or custom user GUIs not showing controls. (T356)
+        - Broken since removal of musewidgetsplugin library months ago.
+          Added PluginWidgetFactory class to handle local creation of controls.
+          (Custom user GUIs must be done by hand since the removal of musewidgetsplugin library).
