This release fixes a serious simulation problem
that caused incorrect results for some functions
on the simulated Classic series calculators
(HP-35, HP-45, HP-55, and HP-80).
This release introduces 82143A printer support (including graphics) for the 41C family, with the ability to save the printer output as a PNG file. The 41C and Voyager keyboard support has been enhanced to provide two-key rollover matching the actual calculators.
