What does this mean?

Sometimes when I see a diagram on the news here on chess.com, there is a strange 'N' after some moves. I don't mean a knight as in 'Nf3', but as in 'c4N'

 

Can somebody tell me what this means?

It stands for Novelty - indicating a reasonable move that hasn't been used in previous games.
