It started off competitively, but it didn't end that way. Stockfish 180614 (i.e. the June 14, 2018 development version) drubbed Komodo 12.1.1 by a 60-40 score, 29-9 in decisive games to take the TCEC season 12 title. (All the games from this season, and previous seasons as well, can be found and downloaded from here.)
Stockfish is still the engine to beat - at least among those running on the sorts of hardware we "regular" people have access to. Congrats to the Stockfish developers, and thanks to them for keeping it free!
