Hey

Recently upgraded my project to 2021.1.17f1 and got several compilation errors. Turned out in my Assembly Definiton assets all of the HDRP references are none now:

Is this something which is known already?
Thanks!

Seems like that’s related to High Definition RP removed from the Packages folder. Is that intended?
