Hey everyone 
!
The PennyLane-Strawberry Fields plugin will not be supported in newer versions of PennyLane. It is compatible with versions of PennyLane up to and including 0.29 (at the time of writing, we are on 0.30).
We recommend that you use Strawberry Fields instead. In the event that you absolutely require the PennyLane plugin, please be aware of the message above!
