* In our testing against its predecessor, Stockfish 16.1 shows a
notable improvement in performance, with an Elo gain of up to
27 points and winning over 2 times more game pairs than it loses.
* Updated neural network architecture: The neural network architecture
has undergone two updates and is currently in its 8th version.
* Removal of handcrafted evaluation (HCE): This release marks the
removal of the traditional handcrafted evaluation and the transition
to a fully neural network-based approach.
* Dual NNUE: For the first time, Stockfish includes a secondary neural
network, used to quickly evaluate positions that are easily decided.
* Use NNUE and UCI_AnalyseMode have been removed as they no longer had
any effect. SlowMover has also been removed in favor of Move Overhead.
- Use %autosetup macro. Allows to eliminate the usage of deprecated PatchN.

%description
|
|
Stockfish is a UCI chess engine derived from Glaurung 2.1. It is not a
|
|
complete chess program, but requires some UCI compatible GUI (like XBoard with
|
|
PolyGlot, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in
|
|
order to be used comfortably. Read the documentation for your GUI of choice for
|
|
information about how to use Stockfish with your GUI.
