We are pleased to announce the release of Dynare 6.5.

This maintenance release fixes various bugs.

The Windows, macOS, MATLAB online and source packages are available for download at [the Dynare website](https://www.dynare.org/download/).

This release is compatible with MATLAB versions ranging from 9.5 (R2018b) to 25.2 (R2025b), and with GNU Octave versions ranging from 7.1.0 to 10.3.0 (NB: the Windows package requires version 10.3.0 specifically).

Here is a list of the problems identified in version 6.4 and that have been fixed in version 6.5:

- Several issues in the nonlinear solver, used in _e.g._ numerical steady state computations, were fixed:

- Optimization would, in rare cases, erroneously apply an infinite penalty function value

- In rare cases, the multivariate diffuse Kalman filter/smoother (`kalman_algo=3`) did not correctly exit the diffuse stage

- The following problems with the `estimation` command were fixed:

- The following problems with non-linear filters were fixed:

- The confidence bands of classical forecasts had incorrect coverage

- Several issues with the `forecast` command used with exogenous deterministic variables (declared with the `varexo_det` command) were fixed:

- The `discretionary_policy` command did not accept the `planner_discount_latex_name` option, contrary to what the documentation says

- The `outfile` option of the `smoother2histval` command would produce an incorrect file on models with two lags or more, leading to incorrect results when loading that file with the `histval_file` command

- OccBin would occasionally crash upon encountering invalid parameter vectors

- The `example1_reporting.mod` example file was broken

As a reminder, the list of new features introduced in versions 6.x can be found in the [release notes for 6.0](https://www.dynare.org/new-dynare-release/dynare-6.0-released/).
