Both CurveExpert Professional and GraphExpert Professional have been updated today, which is a free upgrade for all existing customers.

[UPDATE: 2.5.1 and 1.5.1 are now released, this release fixes odd behavior when closing some graph properties dialogs with the 'x' instead of clicking cancel, and also non-operation of the simple function definition and transformation dialogs in GraphExpert Pro (bug occurred under Windows only). Also, some missing library files in the CurveExpert Pro distribution are now included.]

The major change in this release is that both applications are now 64 bit, on all platforms.  This is for compatibility going forward, and 64-bit operating systems have now been widely available for a number of years.  If you are still running a 32-bit operating system, the last version of CurveExpert Pro you can use is 2.4.0, and the last version of GraphExpert Pro you can use is 1.4.0.  These versions (and the versions below) are all 32-bit.

The second major change in this release is to fix the issues that Mac users were having with both CurveExpert Pro and GraphExpert Pro.  With the most recent operating systems, neither application would even start.  This issue has been fixed, as well as a list of other features specifically for Mac users, such as retina display support and an upgraded user interface.

This migration to 64-bit was an adventure, requiring a great deal of effort.  Much of the software has changed under the hood, although there are only few bugs fixed and no new features added in this release.  The last major migration of the software was back in the CurveExpert Basic days (circa 1997, with Windows 95), when the software was migrated from 16-bit to 32-bit on Windows.

The changelog for CurveExpert Professional is as follows:

• NEW: The software is now 64-bit.
• NEW: Intel Math Kernel libraries utilized for greater processing speed
• NEW: Under macOS, the application uses the Cocoa framework rather than the outdated Carbon framework  This results in more modern/standard graphical interface elements and greater stability in general.
• RESOLVED: The application would not start on OSX 10.11 (El Capitan) or 10.12 (Sierra).  Fixed.
• RESOLVED: Add retina support on macOS for retina displays. [bug 1527]
• RESOLVED: Under macOS, the Help, Preferences, and About menu choices are now moved under the Apple menu as is standard.  [bug 1942].
• RESOLVED: Digitizer did not work correctly on retina displays.  This has been fixed, with the caveat that the crosshair overlay and pink highlighting of points as they are pointed-at, has been disabled.  [bug 1932]
• RESOLVED: Crash when deleting a sorted dataset that was generated from a digitizer dataset.  Fixed. [bug 1900]
• RESOLVED: Background color of the number of divisions for minors control in the graph preferences dialog was miscolored under OSX.  Fixed.  [bug 1399]
