Andrey,

This update is a huge leap forward in the SMath functionality and performance.

Thank you very much for your hard work. I have seen up to 2.5X increase in performance in my worksheets that rely heavily on user defined formulas and excel_IO functionality.

• Numeric library improved to avoid displaying unnecessary "1" in expressions like "1*'unit";

That's really nice, but needs some tweak.
Now, sometimes desirable ones are not displayed, like here:

Discussion regarding calculation issues moved to Why doesn't work in 0.98? topic.

Best regards.

I must admit that I am disappointed by this project. There are so many small bugs that would be easy to fix like SS-48 but instead you optimize speed which is irrelevant with nowadays computer capacity or cloud versions. Also one release per year with minor improvements is not enough for a program that is still under development.

I'd share your disappointment if the speed issues/enhancements were about milliseconds, but there is a bottleneck in the speed for any task related to big matrices (signal processing, image processing, ...), where you can do stuff in seconds or less than a second in the underlying framework, but these actions requires minutes in the worksheet

(Just to mention because was done, I understand that each one has his own priorities and would like to see different things in top of the list)

How can I get rid of the (annoying) reminder to update to latest nightly build? IMHO, it is not applicable to user who choose to go with stable release only.

SS-2291: Displaying of large matrices in equation output improved

How do I view the rest of a large matrix???
