• Prism has a new Fringe slider: set it to 0 for crisp copies with no color split
• Painting a Lens Effects layer's mask no longer makes the effect shift or soften while you paint
• The color picker's OK and Cancel buttons fix rare bug that left the picker stuck open
• Holding Space to pan now shows the hand steadily, with no cursor flicker in the selection tools and the eyedropper included
• The Hand tool has a new open-palm icon
