Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.3. This is a bugfix release. It comes less than 24 hours after the previous release, because version 4.5.2 was affected by a critical bug for MATLAB older than R2016b. The Windows packages are already available for download at: http://www.dynare.org/download/dynare-stable The Mac and GNU/Linux packages (for Debian and Ubuntu LTS) should follow soon. This release is compatible with MATLAB versions 7.3 (R2006b) to 9.3 (R2017b) and with GNU Octave versions 4.2. Here is a list of the problems identified in version 4.5.2 and that have been fixed in version 4.5.3: - `isfile` routine was failing with MATLAB older than R2016b. This bug did not affect Octave. On behalf of the Dynare Team, Stéphane.
