- Full visibility of all data and program memory.

- A paper tape register that supports manual print-out as well as automatic and program trace modes.

Release notes:
Fixed a problem with operations such as rounding (RND function,) on numbers that did not use period for a decimal point.

Removed outdated save behavior on quit. It now conforms better to default behavior and should no longer hang on quit.
