Mantissa,
an UCI compatible open source chess engine by Jeremy Wright, written in Rust,
licensed under the GPL v3.0, first released in September 2021 [2].
Supported by Zahak author Amanj Sherwany, Mantissa v3.0.0, released in December 2021, came with an NNUE implementation of a 769 -> 128 -> 1 net topology.
In Mantissa v3.3.0, released in January 2022, the net topology was changed due to an inspiration from reading Koivisto's source code, considering board symmetry.
Now instead of a 769th feature for side to move, the new net uses 2 sets of 128 neurons in the hidden layer with mirrored weights to reflect the game from the point of views of both sides.
