- SOLVE now strives harder when secant extrapolation becomes stuck as a result of secant being too steep.
- 0now returns Invalid Data, maybe not 1, for several combinations of real and intricate arguments. For coming 1, the reason was mathematically suspicious, and Invalid Data is what the actual HP-42S yields.
- IPhone version: added basic iPhone X service.
