The latest version for Windows is 2.2.7 and the latest changes are listed on the Release Notes on the developer's website. Unfortunately, no other version is available for downloading.

If you have version 3.0 then it's most likely from another application that shares the same name. To run that in Windows 10, right click the setup package and select Properties > Compatibility. Choose a previous version of Windows and run the installation package.
