The data import dialog would display invalid data in the first row if a text file contained a title line only.
The settings for "Factor" and "Offset" are now properly taken into account when deciding if the ticks labels of a graph should be displayed in standard or scientific format.
Inserting columns into a data window could lead to an unexpected mask state in the new columns.
When running a boxplot with non-automatic y-range, pro Fit would erroneously report that there is no valid data to plot.
Exporting the "info" data of a data window into a text file now works properly.
Objects in eps files did not always fill correctly.

Changes between 6.0.6 and 6.1.0:

pro Fit 6.1.0 is the first version that runs natively also on Intel processors (universal binary). It comes with a number of new features. For a detailed (albeit not complete list), please refer to the file "What's new in 6.1". Some highlights are:

pro Fit is optimized for Intel processors.
pro Fit now provides built-in support for mutlidimensional fitting, i.e. for fitting a function with several x- and/or y-values to a data set of the corresponding number of x- and y-columns. The command for multidimensional fitting can be found under the Calc menu.
A new single command called Analysis combines the functionalities of the former Analysis submenu and lets you calculate the values, derivatives, integrals or roots of a function. The command is available in a non-modal window, which is updated dynamically when you e.g. change a function's parameter.
The menu structure and key equivalents have been revised for improved clarity and adherence to Apple's user interface guidelines. Even though this may cause some headaches to those who are used to the previous layout, we believe that it will make anyone's life easier in the long run.
Many dialog boxes have been improved, e.g. all the plotting and the graph options dialogs.

Changes between 6.0.5 and 6.0.6:

pro Fit 6.0.6 addresses the following issues:

DoShell now returns a correct result.

Changes between 6.0.3 and 6.0.4:

pro Fit 6.0.4 is primarily a bug fix release but does also bring some minor new features. The most important changes are:

A new preference option in the 'Drawing' panel allows to set default point line thickness for new plots.
Added a new item 'Special Characters...' in the 'Edit' menu.
EPS files now support a few more characters in addition to the isoLatin1 character set.
The "graph name", "legend name" and "group name" parameters of the plot commands now work properly in apple script
Syntax coloring: If no colored item is found, all text becomes standard text color now.
When plotting data points with the points connected by a line and with part of the points outside the graph, the intersection of the line with the graph frame was erroneously drawn as a data point.

Changes between 6.0.2 and 6.0.3:

pro Fit 6.0.3 provides support for Spotlight in Mac OS 10.4 (Tiger) and later. List of changes:

The whole text content in pro Fit text files (functions and programs) as well as all metadata in any pro Fit file will be indexed and be searcheable with Spotlight.
- This includes any "Comments" (these appear for example in the header of data windows, but they can be defined for all file types) as well as all entries under the Metadata tab in the "Window Properties" dialog box (accessed through the command "Window Properties" in the File menu).
- Copying pro Fit to your hard disk and/or running it once is all you need to make Spotlight aware of how to interpret pro Fit files.
- See the entry under "Changes between 6.0.0 and 6.0.1" below for a description of metadata and how to use it in pro Fit.
BoxPlots are now clipped properly to the range of the independent axis.
The yAxis parameter of the "plot" apple script commands is now interpreted correctly.

Changes between 6.0.1 and 6.0.2:

pro Fit 6.0.2 provides several bug fixes. The most important are:

"Draw Data Points" is now checked by default in the XY-scatterplot dialogbox
The Spline function works again.
Changing the text color for a legend now works correctly.
Changing the metadata for a window now correctly marks the window as modified.
Fixed a bug where specifying only y-errors in a linear fit would lead to a crash.

Changes between 6.0.0 and 6.0.1:

pro Fit 6.0.1 is primarily a bug fixing release. But it also contains some new features. The new features are:

pro Fit files now contain "metadata". Metadata is a set of properties that can be attributed to a document. The presently supported metadata are:
- projects: a list of strings
- keywords: a list of strings
- authors: a list of strings
- copyright: a string
- version: a string
- where from: a list of strings

To set the metadata of a document, bring the corresponding pro Fit window to the front and choose Window Properties... from the File menu. In the dialog box that comes up, select the metadata tab and edit the metadata.

To specify default values for the authors and copyright fields, choose Preferences from the pro Fit menu and go to the metadata tab. In that tab, you can also specify what metadata is to be copied from a data window to a drawing window when a plot of the data from the data window is created in the drawing window.

A "Save State and Quit" command has been added to the pro Fit menu. When you choose it, pro Fit quits immediately without promting you if you want to save any modified files -- rather, pro Fit saves its current state, including any unsaved changes, to a series of temporary files. Next time you start up pro Fit, it loads its state from those temporary files so you can continue your work immediately.

To disable loading the previous state upon starting pro Fit, hold down the Shift key when you start the application.

In addition to these new features, pro Fit contains a large number of minor bug fixes. Here's a partial list:

Slightly modified the algorithm for interpolating contour plots to make it consistent with the algorithm for making color plots.
Plotting a contour plot with a new Z-axis now works correctly.
Fixed an issue where undo would not work properly after updating a graph with new data.
Fixed a bug that could lead to an unnecessary error message when saving drawings.
Writing to TEXT files now works as described, including reopening and appending text to an existing TEXT file.
Bundled pro Fit plug-ins now have the correct icon in the Finder.
Calling SetFunctionProperties(function '', defaultInput 0) produced a wrong error message.
Made various corrections regarding the line thickness of data points.
Goodness of fit is now set correctly also for Robust fit algorithm.
Ungrouping legend now adds point symbols only if necessary.
The "draw points" attribute is now applied correctly when applying a graph style to a graph.
Improved reliability of text representation in Postscript code, in particular for various types of minus signs and other non-standard characters, as well as for italic and bold text.
Improved visual feedback when creating polygons.
Changed a title in the coords window. The rotation angle display now goes from -180 to 180.
Improved performance when generating PDF files containing large bitmaps.
Imported PDF shapes are now correctly scaled (by double-clicking) and rotated (only in 90 degree steps).
File names may now contain several dots (.), i.e. not only before the extension.
Fixed a problem with text sizes when importing drawings saved with pro Fit 5.0 or older.
Text shapes editing dialog box: The option for synchronizing the Symbol font with the Greek keyboard can now be toggled correctly.
Provided a work-around for a bug in MacOS 10.3.x that would lead to parts of rotated texts in drawing windows being clipped when exported as pictures or printed.
Duplicating a legend now retains a picture of the original legend in the copy. Note, however, that this picture is a simple bitmap without high-resolution info.
Improved support of various types of dashes for representing minus signs.
Postscript printing was broken in pro Fit 6.0.0. This has now been fixed.
Disabled the option "Use Quickdraw for Text" for Poscript printing because it is obsolete in MacOS X.
Category axes are now generated automatically generated correctly also along the y-axis.
Improved the interpolation algorithm used in XYZ-contour plots. It now uses a fallback algorithm (Nearest Neighbor interpolation) if the standard modified Shepard algorithm fails. Note: the Nearest Neighbor interpolation does not allow to extrapolate values beyond the beyond the convex hull of the points in the x-y-plane.
Added a checkbox "extrapolate" to the dialog of the command Contour Plot / XYZ Columns. Unchecking this box will prevent the interpolation algorithm from extrapolating beyond the convex hull of the points in the x-y-plane.
When recording some commands to a pascal program, string parameters appeared without the quotes.
Updated the JCAMP-DX reader to recognize all file types.
Corrected a potential crash when closing a function window while syntax coloring was prepared.
Plotting multiple data columns at once works now also if data point symbols are not drawn.
Rotation of circle shapes within a group works now correctly.
Corrected a potential bug with legend positioning if the drawing window is zoomed.
Corrected the parameter name 'onlyActiveParams' in the 'Fit...' command template.
The Draw Points checkbox in the Contour Plot -> XYZ Columns command now defaults to unchecked and its value is observed correctly.
The algorithm for deleting columns now erases the residual columns at the end of the data window.
When entering a registration code in the personalization dialog, the code is stripped now from leading and trailing spaces, tabs, etc.
For some data import settings, the maximum number of columns was fixed to 100. This limit has been increased to 5000.

Changes between 6.0.0 and 5.6.7:

pro Fit 6.0.0 comes with a large number of new features. For a detailed (albeit not complete list), please refer to the file "What's new in 6.0". Some highlights are:

Changes between pro Fit 5.6.0 and pro Fit 5.5.3

pro Fit 5.6 is a Carbon version of pro Fit that runs natively on Mac OS X.
The user application has been redesigned for the Aqua user interface.
On-line help is now based on html and uses Apple's Help Viewer.
Many new or updated external modules (plug-ins) are available. In particular, the 3DPlotterGL module has been updated to export graphs as quicktime movies, and modules for plotting trigraphs (ternary plots), importing HDF data and solving coupled equations have been added.
The pro Fit application is now a "bundle" that contains all the files (including help files) required to run pro Fit .
We have added predefined procedures "SelectShape" and "ExistsShape" and apple script support for selecting shapes and checking for the existence of shapes in drawing windows.
Tags can now also be attached to shapes, not only to windows and programs.
Scrolling by wheel mouse is now supported on Mac OS X.
Exported files now default to a creator code of zero, i.e. no creator code is set per default, so that the choice of which application to use to open those exported files is left to the operating system (other non-zero creator codes can still be set in preferences).
Document files can now be opened even if it is not possible to gain write-access to them. If such a file is opened, the resulting window is immediately dissociated from its origin, so that issuing the "save" command results in the "save as" dialog box.
Added the functions trunc, floor, ceil for internal functions and programs.
Bug fixes.

Changes between pro Fit 5.5.3 and pro Fit 5.5.2

Stationery files are now handled correctly.
A constant JPEGType has been defined for saving drawing windows as JPEG files from programs.
Saving JPEG files with millions of colors does not bring up a floating point error anymore.
The thickness of graph frames is now saved correctly.
Flipping shapes in zoomed graph windows has been fixed to avoid incorrect offsets.
The pop-up menu for date/time conversion in the preferences dialog box has been reworked for better clarity.
Various minor bug corrections and cosmetic changes.

Changes between pro Fit 5.5.2 and pro Fit 5.5.1

User-defined check boxes, radio boxes and other controls in drawing windows can now be disabled by unclickin "Enabled" in the Shape Properties command
Legends load from files with the proper font.
Histograms and skyline plots copy correctly as bitmaps and enlarged pictures.
A window-popup displayed by the Input-command works correctly now.
Columns of types "date" and "time" can be read and set via AppleScript.
Selections in data windows are now always restored properly when opening a data file.
Various minor corrections.

Changes between pro Fit 5.5.0 and pro Fit 5.5.1

Fixed a bug that would generate repetitive "Floating Point" error messages with some polygons.
Fixed several bugs connected with permanent calculations.
Generating a JPEG file with more than 256 colors now works correctly
Fixed a bug that would cause unnecessary network activity when pro Fit had a file open on a remote server.
Fixed a bug that would not allow saving of custom lengths for minor ticks in an axis when saving a file.
The routine to interpret strings with a time format now better handles negative times.
Apple script:
- The script
  set column 1 to {1,3}
  will now only affect the first two cells in the column, while
  set column 1 to 0
  will set the whole column to zero. In other words, passing a list for setting a column only affects the first n entries of the column, wherein n is the number of elements in the list.
- The property "error alerts" of pro Fit is now false by default, i.e. pro Fit returns an error but does not display it locally. If the property is set to true, errors are now displayed correctly.
The calls PlotData and PlotFunction have an additional optional parameter called 'legendEntry'. If this parameter is true, the plot appears in the legend, if it is false it does not appear in the legend. Default is true.
Data windows now remember their scroll state when they are saved and reloaded.
The function window menus now use the latest (1998) CODATA recommended values of the Fundamental Physical Constants.

Run-time errors when a divergent function was displayed in the preview window.
Incorrect display of drawing coordinates in a zoomed drawing window.
Wrong return values of GetResult(chisquared) after a robust fit.
Incorrect parameter standard deviations after fitting with linear regression and no y-errors.
Wrong results when fitting with the Polynomial algorithm and y-errors different from one.
The FPU version inserted wrong signs for data pasted or dragged as text into a data window.
Input('$C...') could display the columns of the wrong data window when it was not used in conjunction with a windows pupup menu.
The align command did not work correctly with polygons that had been rotated as part of a group.
Error-analysis was not possible after robust fitting.
Text columns could sometimes become corrupted when reading data files.
Some menus could be erroneously disabled when closing a window from a program

a module by hand before loading a new build of the modules.

New features in pro Fit 5.1.1:

Added new functions 'InsertString' and 'CopyString' for string manipulation.
Automatic horizontal scrolling while selecting text in text windows.
Improved the data import algorithms for better handling of space-characters.
When re-linking an already linked module to pro Fit (ppc), the previous version of the module is now unlinked before the new one is linked. This obviates the need for removing a module by hand before loading a new build of the modules.

New features of pro Fit 5.1.0

Recording: pro Fit 5.1 can automatically record your actions into a program or an Apple Script. The program or script can then be run to repeat your actions. This makes it possible to tap pro Fit's powerful programming features without having to learn the programming syntax.
New data types and syntax elements: The built-in programming syntax has undergone major improvements. In addition to the data type "real", pro Fit now supports "string", "char" and "comlex" types. Parameters can passed as "var". Many new commands have been added for fitting, plotting and other operations.
Large data windows: Data windows can now have up to 16 millions of rows and columns as long as sufficient memory is available.
Print preview: A command "Print Preview" allows you to preview how your documents will look in print.
Editing axes: New features are provided for editing graphs: Axis labels can have prefix and postfix. Axes can be inverted (i.e. an axis can extend from 1 to -1).
Saving parameter sets: The mechanism for storing parameter sets has been redesigned. You now can attach parameter sets to every pro Fit document. For example, you can store a function's parameters together with its source file.
MacOS 8 support: The new user interface style and contextual menus introduced with MacOS 8 are supported.
... and more: pro Fit 5.1 comes with a large number of other improvements, such as a context sensitive help for programming, improved menu layout, optimization for the new 604e and G3 Power PC processors, enhanced Apple Script syntax, etc.
