names.generate(<TSLM>).approx_normal argument to
forecast(<TSLM>). This allows you to optionally
return forecasts from the more appropriate Student’s T distribution
instead of approximating to a Normal distribution. The default behaviour
remains the same, which is to provide approximate Normal distribution
forecasts which are nicer to work with in model combination and
reconciliation (#343).ETS() will now ignore the smoothing parameter’s range
when specific parameter value is given (#317).ETS() when bounds
= “admissible”.order_constraint (#360).Small release to resolve check issues with the development and
patched versions of R. The release includes some minor improvements to
the output consistency of initial states in ETS() models,
the passing of arguments in ARIMA() models, and handling of
missing values in NNETAR().

computing h-step ahead fitted values, using the
hfitted(<mdl>, h = ???) function. This release adds
model-specific hfitted() support to ARIMA and ETS models
for improved performance and accuracy.
This release adds improved support for refitting models, largely in thanks to contributions by @Tim-TU.
It is also now possible to specify an arbitrary model selection
criterion function for automatic ARIMA() model
selection.

contains some substantial changes to the output of
forecast() methods. These changes to fabletools emphasise
the distribution in the fable object. The most noticeable is a change in
column names of the fable, with the distribution now stored in the
column matching the response variable, and the forecast mean now stored
in the .mean column. For a complete summary of these
changes, refer to the fabletools v0.2.0 release news:
