Dear all,

We are pleased to announce the release of Dynare 6.3. This maintenance release fixes various bugs.

The Windows, macOS, MATLAB online and source packages are available for download at the Dynare website. This release is compatible with MATLAB versions ranging from 9.5 (R2018b) to 24.2 (R2024b), and with GNU Octave versions ranging from 7.1.0 to 9.4.0 (NB: the Windows package requires version 9.4.0 specifically).

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 * Calling model_info with differentiate_forward_vars would crash * The identification command would compute the asymptotic Hessian via simulation instead of via moments as intended * The identification command would crash during prior sampling if the initial draw did not solve the model * The gsa_sample_file was broken * Optimization algorithm mode_compute=5 (newrat) would crash with analytic_derivation * The discretionary_policy command would crash if the model was purely forward-looking * The dsample command would crash * The conditional_forecast_paths block did not accept vector inputs * For MCMC chains with fewer than 6000 draws, the default number of sub_draws used to compute posterior moments was incorrect * Bi-annual dates (e.g. 2024S1 or 2024H1) were not accepted within Dynare statements * Plotting dseries did not correctly show dates on the x-axis

As a reminder, the list of new features introduced in versions 6.x can be found in the release notes for 6.0.

On behalf of the Dynare Team,

Best, Stéphane
