  - Handled filtering case when the series is constant.
  - Added split_smoothing() to smooth series while taking structural
    breaks into account.
  - Fixed legend colors in ggplot2 plots when item names are modified.
  - Added underlying_forecasts(), underlying_forecasts_plot(), and
    ggunderlying_forecasts_plot().
  - Added lines.tc_estimates() S3 method.

                        Changes in version 0.2.2                        

  - Added x13_regarima_outliers() to detect AO and LS on seasonally
    adjusted series.
  - Added smoothness() to compute a smoothness statistic.
  - If n_last_tc = NULL, the value is now automatically set based on the
    MCD statistic.
  - Fixed xlim and ylim parameters in ggconfint_plot(), which were
    previously ignored.
  - Added sa_bar_line parameter to growthplot().

                        Changes in version 0.2.1                        

  - Improved ggplot2 plots layout and customization options.

                        Changes in version 0.2.0                        

  - mcd() now returns the number of periods by default (instead of
    NULL).
  - Fixed local parameterization functions when the series contains NA
    values.
  - In plots, only the last 4 values of the trend-cycle are now dotted
    by default to emphasize higher variability at the end of the series.
  - Added growthplot() function.
