You might have gathered that this year's Hugo Awards have, to put it mildly, a bit of a problem. If not:
Two related groups, calling themselves Sad/Rabid Puppies, respectively, created nomination slates of what they felt should be on the final shortlist (predominantly right-wing, white, male et al) and animated a good number of people to stuff the nomination ballots with these slates. With the results that a good amount of the shortlist now indeed comprises of these artificially elevated entries.
The hubbub surrounding this is not edifying - go read about it at your own peril, regardless what your thinking is in regards to what should be considered 'Good Science Fiction' (it's a question of taste, I suspect).
But here is The Day the World Turned Upside Down by Thomas Olde Heuvelt - the only entry in the Novelette category which was NOT nominated by slate voting - and, given the backlash against said tactics this might well mean that the awards will equate 'only' with 'best' and will thus award Heuvelt a Hugo Award for it.
I would suggest you have a read yourself, and make up your own mind if this story, published in Lightspeed Magazine in April 2014, can be considered the best short story of the year (that one is a question of taste, too!).
