We are pleased to announce the release of Dynare 4.6.3.
This maintenance release fixes various bugs.
The Windows, macOS and source packages are already available for download at
[the Dynare website](https://www.dynare.org/download/).
All users are strongly encouraged to upgrade.
This release is compatible with MATLAB versions ranging from 7.9 (R2009b) to
9.9 (R2020b), and with GNU Octave versions 5.2.0 (under Windows) and 4.4.1
(under macOS).
Here is a list of the problems identified in version 4.6.2 and that have been
fixed in version 4.6.3:
* Using an unknown symbol in `irf_shocks` option of `stoch_simul` would lead to
a crash of the preprocessor
* `discretionary_policy` would crash in the presence of news shocks
* `identification` would crash for purely forward-looking models
* The `endogenous_prior` option did not properly handle missing observations
* The auxiliary particle filter with pruning and resampling would crash
* Initialization of the state variance for particle filters was buggy
* An `@#else` clause after an `@#ifndef` was not correctly interpreted
* An `@#elseif` clause after an `@#ifdef` or an `@#ifndef` was not correctly
interpreted
* Perfect foresight simulations of models with a single equation would crash
when using either the `lmmcp` option or the `linear_approximation`
* Inequality constraints on endogenous variables (when using the `lmmcp`
option) were not enforced on purely backward or purely forward models
* Perfect foresight simulations with `bytecode` and `block` options could crash
if there was a purely forward variable whose value in all periods could be
evaluated backward (typically a process of the form `y=a*y(+1)+e`)
* `extended_path` was broken with `bytecode`
* Under Windows, with Octave, the k-order perturbation and MS-SBVAR MEX files
could not be loaded
* On Fedora (and possibly other GNU/Linux distributions), compilation from
source would fail against Octave 5
As a reminder, the list of new features introduced in versions 4.6.x can be
found in the [release notes for
4.6.0](https://www.dynare.org/new-dynare-release/dynare-4.6.0-released/).
