Available releases

The Linux build requires appropriate version of Qt to be installed.

The Windows build with vs13 suffix(built with Visual Studio 2013) has no external dependencies.

The Windows build with vs17 or vs19 suffix (built with Visual Studio 2017 or 2019) requires the redistributable package for Visual Studio 2015 - 2022.

The Windows build with vs10 suffix is built with Qt4 (legacy) - in contrast to the other builds that are with Qt5 (recommended). It is prepared for the purpose of backward compatibility with old versions of Windows (i.e. XP), and may be lacking some of the features.
