Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.5. This is a bugfix release. The Windows packages are already available for download at: http://www.dynare.org/download/dynare-stable The Mac package will follow soon. This release is compatible with MATLAB versions 7.5 (R2007b) to 9.3 (R2018a) and with GNU Octave versions 4.2. Here is a list of the problems identified in version 4.5.4 and that have been fixed in version 4.5.5: - Identification was crashing during prior sampling if `ar` was initially too low. - The `align` method on `dseries` did not return a functional second `dseries` output. - Predetermined variables were not properly set when used in model local variables. - `perfect_foresight_solver` with option `stack_solve_algo=7` was not working correctly when an exogenous variable has a lag greater than 1. - `identification` with `prior_mc` option would crash if the number of moments with non-zero derivative is smaller than the number of parameters. - Calling several times `normcdf` or `normpdf` with the same arguments in a model with block decomposition (but not bytecode) was leading to incorrect results. On behalf of the Dynare Team, Stéphane.
