Search parameters were tuned at 60+0.6 8-thread. Link to the tuning attempt: https://tests.stockfishchess.org/tests/view/65b84e8dc865510db0276030 The most significant change is the triple extension parameter, from 200 to 78. This presumably improves scaling. Additionally, the value < singularBeta - 2 condition for double extensions was removed. This can simply be considered a parameter tweak from 2 to 0.
