Incompatibility with latest Xamarin.Forms 2.1.x

Hi 
is this library still supported? 
I  gest this error while loading the nuget package:

```
Unable to resolve dependencies. 'Xamarin.Forms 2.1.0.6524' is not compatible with    
'SolTech.Xamarin.Forms 1.0.25 constraint: Xamarin.Forms (≥ 1.4.2.6359 && < 2.0.0)'
```

thanks
