CoreELEC 20.0-Nexus Amlogic-ng Discussion

I am new to using CoreELEC. This is the first time I have updated, going from 19.5 → 20.0. Can anyone tell me how to go about installing Inputstream Adaptive? I see that it was an issue with installing on rc1 but according to this it should have been fixed with an update. Has it been fixed and if so could someone please tell me how to install the update?
