Changes in version 1.0.0 (2026-10-22)                  

First stable release. The public API documented here is covered by a
stability promise: renames or removals after 1.0 go through a
deprecation cycle.

New features

  - geom_slice() — full rewrite as a proper ggplot2 Layer subclass.
    Draws slices of a fitted lm across the plot and its facets, with
    grouping, faceting, automatic back-transformation of transformed
    responses, multi-value predict_vars (values crossed into multiple
    lines), and interval = "confidence" / "prediction" bands.
  - geom_slice_caption(), geom_slice_subtitle(), geom_slice_text() —
    annotation helpers that report the model, held values, and line
    labels.
  - autoplot() method for lm objects — scatter + geom_slice(...,
    interval = "confidence") + geom_slice_subtitle() in one call, with
    model summary printed to console for easy exploration and iteration.
  - lm_equation() / lm_latex() — plain-text and LaTeX model equations,
    with clearer factor formatting.

Deprecations

  - geom_fit() — removed; calling it errors with guidance to
    geom_slice().
  - drawit() — deprecated in favor of slice_2d() / add_slice_2d().
