## 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.
