v2.1
No changes in any of the numerical algorithms, all changes in this version are interface related. There is a new user interface for problem definition. Natural language can be used to specify a problem, for example 'solve y = cos(y)'. In this new interface, graphs are automatically generated. For experienced users who prefer the original user interface, that interface is still available.
Autoscaling is now the default behavior of graphs but can be disabled whenever axis properties are modified. Clicking on a graph component, an axis for example, or a title, or a curve, brings up the corresponding editor.
Curves, points, and links now have the ability to switch solvers automatically. This can be a convenient feature during problem development, when different solvers are being tested until the right solver is found.
