Reading the changelog in my opinion it makes sense on the communication front since we have been working on getting communications improved for the better part of the year without much progress by some measures so a downgrade made sense.
But it is more than 1 (since there is communication and 0 would be the absense of it 1 seems a tad low)
The prisma was an issue but the way it was handled was good so seems like a fair decrease for now.
It did make me look at all the competitors quite a few.
Good stuff haven't checked in a while.
