  - add_fan(), add_classification(), reference_shape() and
    reference_text() adds support for plotly::plot_ly().
  - change_breaks() generate nice breaks on a logarithmic scale.
  - format_ci() gains a change argument, mostly useful in combination
    with percent = TRUE. This converts 80% to -20% and 120% to +20%.

  - stat_effect() uses text symbols with a circle background.
  - Added a NEWS.md file to track changes to the package.
