[Joseph Walrath]

Hi Kurt, 
Thanks for taking the time.  Is 6.2 fully backwards compatible with 6.1?

> •	Built-in Python support. Python within pro Fit is a full equivalent of pro Fit's own, built-in Pascal scripting language and can be used for defining pro Fit programs and functions. Python is a mature programming language with a rich feature set well-suited for scientific calculus, and it allows you to tap a vast choice of scientific libraries, such as numpy and scipy. For more information, search pro Fit's on-line help for Python, and have a look at "Example Files/Python", and in particular the "Python Read Me" file therein.

> Various built-in functions that had arguments named 'from' and 'to' have the names of these arguments changed (in most cases to 'first', 'last') in order to avoid incompatibilities with Python. For pascal scripts, the old names are still supported for backwards compatibility.

> •	Pascal: New type UnicodeString for Pascal scripts. It can be used more or less in the same manner as a normal string, but it has unlimited length and supports unicode characters
> •	Pascal: Some of the functions that can be called by Pascal-Macros now have named parameters: OpenDataSet, OpenCurve, AddDataPoint, SetLineStyle, SetFillPattern, DrawText (the old-versions of these calls without named parameters are still supported, though, for backwards compatibility).

> •	Added a command Apply Style to the Plot menu which allows to apply a graph style to one or more graphs in a drawing window, thereby simplifying the creation of a series of graphs with common style settings
