================================

Bugs fixed:
-----------
* Fix for selecting area in graph window using pen (zoom box, selecting integration area) not working on OS 5 devices.


Version: 3.1.1
==============

Bugs fixed:
-----------
* Fix for graphics not working on Sony hi-res OS 5 devices.
* Windows installer should no longer cause a GPF or other failure for some Palm user names (including 20 character names).


Version: 3.1
============

Bugs fixed:
-----------
* Has hi-res (320x320) support for OS 5.0 devices including hi-res Launcher icon, hi-res graphics for keypads, hi-res graphing.
* Has support for graphing on AlphaSmart Dana device in upright or sideways full screen mode.
* Uses p1 Finance lib v1.0 if available, does not complain if an incompatible is detected.


Version: 3.0.6
==============

Bugs fixed:
-----------
* Does not try to use any libraries - therefore should only be for users that have p1 Finance 4.x installed which has a Finance Library that is incompatable with p1 Graph 3.0.x


Version: 3.0.5
==============

Bugs fixed:
-----------
* Not being able to do rref correctly on matrices that contain all negative numbers and a single zero


Version: 3.0.4
==============

Bugs fixed:
-----------
* Under certain circumstances the unary operator preference of "-2^2=4" was ignored and instead functioned as "-2^2=-4".


Version: 3.0.3
==============

Bugs fixed:
-----------
* When there are too many variables in a solver equation to fit on one screen, cannot enter values for variables that are not in the first screen.
* Manual is updated with information on the integral, derivative and rectangular/polar converson functions.
* Max decimal places reduced to 12 to fix floating point display problem - certain fractional numbers would be represented by recurring decimals, eg:
"CE/C,3.4+4.5+4.8+7.5+18.1+26.6+31.9,=,+/-,+,100,=" yields "3.19999999999999" instead of "3.2"
* The rightmost number of the results in the stats results worksheet can be clipped
* Could not select integral range in graph mode by drawing a box from right to left.

* Has two lines for entering solver expression


Version: 3.0.1
==============

Bugs fixed:
-----------
* While entering a solver equation, hit the place where the "recycle/last result" button normally appears will bring in your last result, or if the last result was a table/matrix it switches to the table/matrix view screen.
