UpdappLumia exclusive Call+SMS Filter app, which is currently the only working contact blocking and filter app on Windows 10 Mobile has received an update. The app is not available in Windows 10 web store somehow and there are no visible changes for the app.

We can certainly assume bug fixes and performance improvements though. The install link given below should work on devices directly but will give you an error if your try to open in the Web store.
