Announcement for Dynare 5.5 (on 2023-10-23)
|
||||
===========================================
|
||||
|
||||
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`

||||
