Does Xamarin forms supports Windows Phone 8.1 RT app development ?

i am new to Xamarin forms, i wanted to target the windows phone 8.1(RT) app instead of windows phone 8.
but, it seems that Xamarin forms doesnt support Windows phone 8.1 RT apps.
Also, System requirement at below link says "Xamarin.Forms applications that support Windows Phone Silverlight 8 require". Does that mean Xamarin forms only support windows phone 8 or windows phone 8.1 (silverlight) apps and not windows phone 8.1 RT apps ?
