GraphExpert Professional 1.6.0 has been released for both Windows and macOS (Linux version is to come). Along with the changes noted below, the application is now code-signed for your security. You might get SmartScreen alerts because this is a new release, but it should soon no longer interfere with the installation process.

GraphExpert Pro has had a mountain of under-the-hood modernization updates that are necessary to carry it forward with future development. The underlying Python distribution has been upgraded to Python 3, and the UI toolkit has been upgraded. With this, the overall stability of the software is improved, and common problems like being unable to run the software from a directory that has "exotic" characters is possible. Also, the calculation speed has been nearly doubled because of the leveraging of optimized machine-specific algorithm implementations particularly for the nonlinear regression algorithm.

Two new graph themes have been introduced; Dark Pastel, and Light Pastel. These modern themes let you easily apply very attractive styling to your plots; an example is below:

In addition to what has been discussed above, the following changes have been implemented:

• Application is now signed with an SSL certificate
• Improvements to locale/region behavior; application now always conforms to region settings for numerical formatting.
• SVG equations in documentation
• General documentation improvements
• Creation of over 700 unit tests for continuous integration
• PDF documentation now included with the software along with HTML.
• Added support for macOS High Sierra, Mojave, and Catalina

• Two new graph themes: Dark and Light Pastel
• Application is now signed with an SSL certificate
• Upgraded to Python 3 and wxPython 4.1.0. Stability improved. Should be able to run CurveExpert Pro from any directory now.
• Improved speed to due to leveraging optimized machine-specific algorithm implementations
• Improvements to locale/region behavior; application now always conforms to region settings for numerical formatting.
• SVG equations in documentation
• General documentation improvements
• Creation of over 700 unit tests for continuous integration
• PDF documentation now included with the software along with HTML.
• Added support for macOS High Sierra and Mojave

and the following defects have been addressed:

• Even if a plot's coloring was dark, a white border was imposed when that plot was saved as svg/png/jpeg/etc. Fixed.
• Changing visibility of graph title via the small dialog did not work. Fixed.
• Digitizer: points did not properly highlight on macOS, so point cannot be deleted. Fixed.
• Improved UI in the graph theme manager
• fixed trial license manager not working on macOS
• fixed that points in key and number of columns in a legend could be erroneously set to zero
• fixed bug where reading in datasets over 5000 points would cause serious graphing problems.
• removing rows is disallowed if the data set has none (spreadsheet)
• fixed sorting errors in the graph interactivity section
• plus (+) graph addition button did not work correctly in certain situations. Fixed.
