* A new menu command (View > Display Mode > Toggle) and a new keyboard shortcut (Ctrl+<keypad 5>) switch the display mode from Normal to Outline and back.

* An object with mask and/or clipping path, when viewed in Outline mode, now displays both the object itself and its clipping path and mask as objects, using different outline colors. By default, clippaths use green outlines, and masks use blue. These colors, as well as the colors of the regular object outlines (default black on light background and white on dark background) are now changeable by editing the "wireframecolors" group in the preferences file (~/.inkscape/preferences.xml).

* An object with no fill and no stroke, invisible and not selectable by mouse clicking in normal more, can now be picked by a mouse click in the Outline mode using its visible outline.

* To cater for specialized uses, such as preparing input for personal media cutters, Inkscape now has an option to start in the Outline mode upon launch. To enable this, add the following line to your preferences.xml file:

<group id="startmode" outline="1"/>

placing it after the <group id="options"> opening tag.
