The keyboard issue in cupcake has been fixed in this version. Further cupcake support will come in the future version.
And the % button in the screen keypad has been removed. People always complain about 100-25% doesn’t equals 75%, while handyCalc take 25% as 0.25 (there is no data type for percentage in the core). The logic is confusing, so I do not recommend to use it. But you can still type % in your hardware keyboard to use it.
