Release Notes: The default graphics device for non-interactive use is now pdf() rather than postscript(). The default width and height for pdf() and bitmap() have been changed to 7 inches to match the screen devices. Most users of the X11() device will see a new device that has different fonts, anti-aliasing of lines and fonts, and supports semi-transparent colors. Considerable efforts have been made to make the default output from graphics devices as similar as possible (and in particular close to that from postscript/pdf). There were many other enhancements.
