DSL: We have added a new function named smooth, which makes it easy to create a smoothed version of a signal.
This can be useful to apply to KPI mapping proxy signals, both to make the resulting charts cleaner, and to make
the forecasting more stable with less volatile model revisions. For more information, see the
reference documentation.
DSL: We have added a new function named drop_last, which can be used to remove the last data point(s) from
a time series. For more information, see the reference documentation.
