Did Diana Riggs really pass away??

So there was a thread a while back about Diana Riggs passing away... yet I see that she is playing Mrs. Pumphrey on the new PBS version of "All Creatures Great and Small"! Was it all filmed before she passed or are "rumors of her demise greatly exaggerated"?

She was a fantastic Mrs Emma Peel. šŸ˜Š
Yes indeed, she sure was.
