The main feature is an architectural change allowing me to add new functions and operations easily. The current release comes with more than 50 new commands, among them solving the quartic equation, solving linear equations in 1 to 9 unknowns, a prime number test, matrix operations and more. All of them are programmable, of course.

Above all, I've finally implemented numerical integration and a root finder, loosely patterned after the HP-34. I'd love to hear from the community if these functions work for you. Did I miss anything? Examples of use may be found here.

I'd also like to hear if there are still functions or operations you're missing on RPN-67/97. Any suggestions or wishes?

Congratulations, what a beautiful and powerful simulator pair, you've raised the ante! It's worth buying an iPad just to have it ;-)

PS. Definitely an android version will be *great*.
