This is a minor update that updates the wxWidgets library, the compiler used and fixes a bug with skin families.
A new version of model viewer is planned that will use SharpLife and WPF Core (slated for release with NET Core 3 in the second half of the year). A port to Avalonia will be done when that framework is stable to provide cross platform support.
Note: this release contains wxWidgets binaries that will not overwrite the older ones. Manually remove the old binaries from your installation if you do not want them to take up space.
You will need the VS 2017 x86 redistributable, which you can download here: https://support.microsoft.com/en-gb/help/2977003/the-latest-supported-visual-c-downloads
