We are pleased to announce the release of Dynare 5.5.

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 8.3 (R2014a) to 23.2 (R2023b), and with GNU Octave version 8.3.0 (under Windows).

Note for macOS users with an Apple Silicon processor: this is the first Dynare release that comes with native Apple Silicon (arm64) support under MATLAB. Please download the corresponding package, to be used with MATLAB R2023b for Apple Silicon.

Here is a list of the problems identified in version 5.4 and that have been fixed in version 5.5:

- In a stochastic context, results could be incorrect if an endogenous with a lead ⩾ 2 or an exogenous with a lead ⩾ 1 appeared in the argument(s) of a call to a (nonlinear) external function
- With the `use_dll` option of the `model` block, the expression `sign(x)` would evaluate to ±1 instead of 0 if `x=0`
- If the guess value given to the `steady` command was such that the residuals were all below tolerance, except some that are `NaN`, then this guess value was incorrectly accepted as the solution to the steady state problem
- The `method_of_moments` command with GMM was ignoring the `analytic_standard_errors` option when using `mode_compute=4`
- Homotopy with the `extended_path` command at `order=0` was broken
- The `parallel_use_psexec` command-line option was ignored
- With the `bytecode` option of the `model` block, using the operators `abs()`,  
`cbrt()` and `sign()` would lead to a crash
- The `fast` command-line option was broken under MATLAB with Windows
- Ramsey steady state computation could fail if an `expectation` or `diff` operator was present in the model
- A crash could occur if some external function call was present in an auxiliary variable
- The `endogenous_prior` option of the `estimation` command could erroneously display a warning message about missing observations
- The `model_comparison` command would crash if the `.mod` file name had less than four characters
- The `shock_decomposition` command would overwrite previously stored smoother results
- The `x13` interface in dseries did not handle missing values, particularly at the beginning of a series
- The `x13` interface in dseries would occasionally crash under Windows with segmentation violations
- OccBin: estimation would crash if a previous `shocks(surprise)` simulation was conducted
- The `internals` command would not find the location of the `_results.mat` file
- The `prior optimize` command would not work with `mode_compute=5`

As a reminder, the list of new features introduced in versions 5.x can befound in the [release notes for  
5.0](https://www.dynare.org/new-dynare-release/dynare-5.0-released/).
