paul-buerkner/brms v2.21.0 on GitHub

Add experimental support for the pathfinder and laplace algorithms
in the cmdstanr backend. (#1591)
Automatically recompute fit criteria previously stored in the model
if potentially results-changing arguments are provided to the criterion method.
Allow to turn off automatic broadcasting of constant priors.
Allow for joint likelihood evaluation in kfold via argument joint.
Use several Stan built-in functions implemented since version 2.26
to improve the efficiency of multiple model classes. (#1077)

Change make_stancode and make_standata to be aliases of stancode and
standata, respectively. Change get_prior to be an alias of a new generic
method default_prior. This enable other packages to define new stancode,
standata and default_prior methods to generate Stan code and data, and extract
the default priors, for their own objects building on brms. Thanks to Ven Popov
for helping with this. (#1604)
Change the default prior of the shape parameter of negbinomial models
to inv_gamma(0.4, 0.3) thanks to Aki Vehtari. (#1614)
No longer automatically canonicalize the Stan code if cmdstanr is used
as backend. (#1544)
Export read_csv_as_stanfit thanks to Ven Popov. (#1619)
Make installation of shinystan optional. This means that the package has to
be loaded, via library(shinystan), before launch_shinystan can be used. (#1595)
Improve parameter class names in the summary output.
Show histograms rather than densities in the plot method by default.
Deprecate argument N in the plot method in favor of argument nvariables.
Remove deprecated argument exact_loo in method kfold.

Remove some remaining uses of Stan's old array syntax.
Fix a bug in formula parsing of missing values terms with interactions
thank to Guido Biele. (#1608)
Ensure compatibility of combine_models with moment matching. (#1603)
Ensure compatibility with the latest splines2 package version. (#1580)
Fix output of rmulti_normal thanks to Ven Popov. (#1588)
Prevent memory leaks when executing kfold or reloo in parallel.
