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.

==Komodo 14==
Komodo '''14''', released in May 2020 with following improvements announced by [[Larry Kaufman]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=73916 Komodo 14 released] by [[Larry Kaufman]], [[CCC]], May 12, 2020</ref>:
The improvements cover a wide range of issues, including [[Extensions|extensions]], [[Null Move Pruning|null move]], [[King Safety]], [[Time Management|time management]], and many more. There is one new feature added since Komodo 13.3, "[https://en.wikipedia.org/wiki/Fast_chess#Armageddon Armageddon]" mode, which tells Komodo that White (or Black) must win, draws are scored as losses for that color. When draws are counted as losses for White, knowing this improves Komodo's performance as White by about 30 elo according to our tests. In Armageddon mode, the specified color (usually White) not only avoids clear draws, but adjusts [[Contempt Factor|Contempt]] by an amount we determined was most helpful for Armageddon play. Testing on one thread in Armageddon mode suggests that on a modern laptop, if White gets one minute total plus 1% increment, and Black gets half a minute plus 1% increment plus draw odds, then chances are fairly close to balanced. Other features added since Komodo 13 include more levels, Personalities, and Auto-Skill. Standard mode remains the strongest when [[Principal Variation#MultiPV|Multi-PV]] is not in use, while [[Monte-Carlo Tree Search|MCTS]] mode is generally strongest when both are using Multi-PV.
