- Update to 17.1:
  * Quality of chess play
    In our testing against its predecessor, Stockfish 17.1 shows a
    consistent improvement in performance, with an Elo gain of up
    to 20 points and winning close to 2 times more game pairs than
    it loses.
  * New speedtest command
    The new speedtest command benchmarks your computer's performance (measured
    in nodes per second) using a realistic and stable test. To run it, you'll
    need command line access—give it a try and share your results with the community!
  * Improved hardware support
    Stockfish is no longer limited to 1024 threads and will allow users to specify
    whatever their system is capable of. Additionally, hardware such as ppc64 and
    Loongson is now better supported at build time.
  * Bug fixes for tablebase support
    Our previous release introduced improved engine lines (principal variations)
    ending in mate as soon as a mate score is announced. A side effect of this
    improvement was a rare corner case involving cursed tablebase wins, only relevant
    in correspondence chess when the 50-move rule does not apply, which has now been
    fixed. Relatedly, time management has also been improved to avoid potential time losses.
