The changes from Komodo 12 to 13 in MCTS mode (which is where most of the changes were made) are so vast and pervasive that it is hopeless to even try to enumerate them. The elo gains are in the 300 to 400 range on any number of threads, so it's really a very different engine. Virtually every aspect was improved, some of the changes being rather radical. Most cannot be explained without describing in detail how Komodo MCTS works, which is pretty unique. As for regular Komodo, there were quite a few changes, but only a few that show up as measurable elo gains on one to four threads. To be honest, if you never use [[Principal Variation#MultiPV|MultiPV]] or MCTS mode, don't have more than a few cores, and already own Komodo 12, I wouldn't recommend spending the money for Komodo 13 unless the cost is insignificant to you. But I think that most people do use MultiPV, and if so Komodo 13 MCTS is clearly better than Komodo 12 in either mode.
