StockNemo A Chess Engine written in C# trying to find good moves like Stockfish. UCI Compatible. Author: Shaheryar Sohail v.4.0.0.1: Implement UCI Go Command: Moves To Go. by @TheBlackPlague in #51 This release is a UCI command improvement. Thus, does not require ELO Difference. You may notice positive ELO Difference on repeating TCs, though, as it targets that. Stocknemo Sea  Hammerhead  4.0.0.0  download from page

KhepriChess - java (UCI) chess engine v.2.0.0: This release features a full code rewrite of v1. Much of the core logic is the same, but the code has been improved (both in readability and in performance). KhepriChess 2.0.0 download from page

Larry Kaufman: "We have released Dragon 3.1 at komodochess.com, which today won the World Computer Chess Championship after a tiebreak match with Lc0. Dragon uses NNUE (Neural Network Updated Efficiently) technology, originally developed for the game of shogi. Komodo has a great deal of chess knowledge in its evaluation. Training an NNUE network based on this evaluation was both an advantage and a challenge, requiring experimentation with architectures and data generation of billions of positions. The reinforcement learning phase for Dragon is in its infancy, but is already showing great promise." More

Avalanche - UCI (NNUE Chess Engine) Author: SnowballSH  Rating CEDR=2620 v.1.1.0: This version includes an optimization of NNUE (using Zig comptime features), addition of Singular Extension, Multicut, and more aggressive pruning factors. Choice of binary Avalanche currently does not support 32-bit systems. First, find your OS name (linux, macos, windows). Then, if your CPU is 2013 or newer (Intel Core i3 or newer, or any CPU supporting POPCNT), you should select the Haswell one (This should be the case for most users reading this sentence). If you have a 2013 or older CPU, choose the one without haswell. Haswell binary performs a lot faster than the general one. If you are unsure, use the haswell first and if it crashes, use the general one.
