• corrects an error in handling of colour burst amplitude within the OpenGL scan target that could cause a bright green display if a colour screen was paired with a machine that does not provide a colour burst — in practice, the Apple II in text mode was the primary victim;


• corrects an error in my Qt bindings which object sliced a keyboard class, potentially affecting any keyboard that deviates from the default — in practice, the Apple II was the primary victim as it uses non-positional, logical input almost exclusively;


• improves the SDL target's handling of logical key symbols, affecting any and all machines with the logical keyboard mapping enabled; and


• increases the range of keys that can be used as reset on an Apple II. It's now any F key, or those in the page up/down/delete/etc cluster on a standard PC keyboard.
