Functional Changes
------------------

FreeType processed fonts will appear spaced more closely and slightly taller and narrower due to a correction in the determination of height to width ratio.

There has been a change in the way printing is handled. ``HOutputHandlerOptions::UseSubscreen`` is now deprecated in favor of ``HOutputHandlerOptions::Layout(HOutputHandlerOptions::Print_Layout)``. The layout parameter can specify one of WYSIWYG, FULL_PAGE, or MAPPED_CAMERA.
