- Allow for on-the-fly variable declaration in equation tags (see 01d5a1308244ffb5a85e7f8f1d6a9e104b458715)
- Previously, when some MEX files were missing, Dynare would automatically use a slower M-file functional alternative; this is no longer the case. It is however still possible to manually add these alternatives in the MATLAB path (they are located under `matlab/missing/mex`; this only applies to the `mjdgges`, `gensylv`, `A_times_B_kronecker_C`, `sparse_hessian_times_B_kronecker_C` and `local_state_space_iteration_2` DLLs)
