- performance optimization to pruned state space system and lyapunov solvers (Dynare/dynare!1749, Dynare/dynare!1745, Dynare/dynare#1737)
-`debug`-option of `perfect_foresight_solver` allows checking singularity of Jacobian for `sim1` and `sim1_linear`(https://git.dynare.org/Dynare/dynare/-/merge_requests/1834)
-`stoch_simul` now supports theoretical moments at `order=3` with `pruning` (dfc73576) and will report second moments based on the pruned state space if the `pruning`-option is set (https://git.dynare.org/Dynare/dynare/-/commit/4cf9f7d1a7fa5dac8f91ff3344a6114c7f15959c)
-`discretionary_policy` is now able to solve nonlinear models (it will then use their first-order approximation, and the analytical steady state must be provided) (!1792)
