 Here is a list of the problems identified in version 6.2 and that have been
 fixed in version 6.3:
 
-* OccBin with option `smoother_inversion_filter` would crash the MCMC estimation if the `filtered_variables` or `filter_step_ahead` options were used
-* OccBin with option `smoother_inversion_filter` would use the PKF if `mh_replic>0`
-* OccBin with option `smoothed_state_uncertainty` would crash Dynare if the MCMC smoother was run after the classical one
-* OccBin's smoother would crash when encountering an internal error due to the output of the linear smoother not having been computed
