*`perfect_foresight_with_expectation_errors` command crashes with `homotopy_marginal_linearization_fallback` option if there are several distinct `shocks` or `endval` blocks with the `learnt_in` option (bug fixed in 85bea5a68bcee16fe3c707c62e34bef56608e056)
*`model_diagnostics` with the `bytecode` option will crash if the static Jacobian is singular (bug fixed in e58c12555798c3cdb1b1bf991502b08b32dcd299)
*`discretionary_policy` with the `noprint` option will crash when encountering a problem instead of continuing (bug not yet fixed, see https://git.dynare.org/Dynare/dynare/-/merge_requests/2349)
* Using the `forecast` command with a model solved at `order=2` with `varexo_det`, Dynare would return uncertainty bands based on a first-order approximation (bug not fixed, see #1940)
