* PAC: iterative OLS is broken (bug fixed in 3aeb1ff7)
* Perfect foresight simulations
* the `debug`-mode did not preserve sparsity, causing out of memory errors (bug not yet fixed, see https://git.dynare.org/Dynare/dynare/-/merge_requests/2111)
* the `debug`-mode did not preserve sparsity, causing out of memory errors (bug fixed in bbdcdc89)
* Estimation:
* the computation of prior/posterior statistics would crash if `filter step_ahead > 1` without requesting `forecast` or the `smoother` (bug not yet fixed, see https://git.dynare.org/Dynare/dynare/-/merge_requests/2114)
* Forecasts are only based on the DSGE-model, not the DSGE-VAR (bug not yet fixed; see #819)
* The `contemp_reduced_form`-option of the `sbvar`-command is broken (bug not yet fixed, see #1716)
