OptiPath is continually in development. Please use it at your own risk. It is performing well for us on a Windows 8.1 operating system.
The version of OptiPath you are using is given on the splash screen at startup.
At any time you can get the version from the About OptiPath dialog by clicking on About on the Help menu. The version number will be of the form YY.MM.DD.N (for example 14.01.14.2) where YY.MM.DD is the date (year, month, date) of the release and N is the release number. More recent versions (15.01.22.1) will have a larger version number than older releases (14.01.14.2) (1501142 > 1401142).
Please let us know what you think of the OptiPath software. Any bugs you find, any suggestions you have for improving the interface or the functionality. We welcome it all. Thank you.
