Thanks for the interesting digest! I didn't know about the $unionWith feature, great to know one can combine different collection results 😀

No problem! We're aiming to provide one every Monday :)

Yes! $unionWith has been a highly requested aggregation pipeline stage, so we're pretty happy it was released in 4.4! I'd be happy to hear your thoughts on the tutorial and see if anything's missing or unclear.
