Plus42 history

2022-05-17: release 1.0.4

* TVM: Fixed error checks in N.

2022-05-13: release 1.0.3

* SOLVE now handles functions that are always positive or always negative a bit
  better, reporting Extremum when the iteration appears to be bouncing around
  without improving, instead of continuing indefinitely.
* PLOT now detects <Not a Number> in XMIN/XMAX/YMIN/YMAX and reports Invalid
  Data, instead of freezing.

2022-05-09: release 1.0.2

* Added code to prevent freeze in PLOT under certain circumstances.

2022-05-09: release 1.0.1a (Android only)

* Fix for crash on startup with Android versions before 4.3.

2022-05-05: release 1.0.1

* DIM "X", when X existed but was not a matrix, would cause a crash. Fixed.
* Equations: NOT was broken, not recognized as Boolean operator. Fixed.
* Equations: Added TYPE? and UNIT? functions.

2022-05-05: release 1.0a (Windows and Linux)

* More efficient display updating, so long-running programs that update the
  display a lot don't waste a lot of CPU time repainting the display faster
  than the human eye can see, and spend more time actually running the program
  instead. Note that this update is for Windows and Linux only, because the
  Android, iOS, and MacOS versions already worked this way.

2022-04-27: release 1.0

* Based on Free42 3.0.11, with the addition of: a larger and resizable display,
  algebraic equations, attached units, directories, time value of money and
  amortization schedules, and function plotting.
