=== Important Notes ===
{{Attention|There are mandatory Xaml changes and existing customizings need to be updated. See {{#switchtablink:Xaml_Changes|Xaml Changes}} tab.}}
{{Attention|Starting with from this version, [https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1709_(Fall_Creators_Update) Windows 10 build 16299] or later builds are required.}}
{{Attention|Starting from this version, the WinX/UWP app will also be available on the public Microsoft Store (named UBIK.UWP). Unfortunately, this leads to a different app identity which means the previous versions (up till 3.5) of the app must be uninstalled first and existing app data (including and not limited to profiles, databases, XAML customizings will be lost unless they are manually saved and restored.}}
