New features:

• add pdf and cdf computed variables for the stat_sample_slabinterval() subfamily. See new examples of usage in the last section of vignette("slabinterval"). (#11)
• add cut_cdf_qi() for creating (amongst other things) interval-filled halfeyes, in the style of bayesplot::mcmc_areas() (#11)
• add fill_ramp and color_ramp scales to geom_slabinterval() and geom_lineribbon() families, making it easier to separate group colors from interval/density/CDF colors. See new examples in vignette("slabinterval"), vignette("lineribbon"), and vignette("freq-uncertainty-vis"). (#16)
• auto-detect finite limits on analytical distributions, so (e.g.) distributions like the beta will not cut off tails close to 0 or 1. (#18)
• add brms::brmsprior implementation for parse_dist() (#34)

New documentation:

• vignette("freq-uncertainty-vis") now uses distributional::dist_student_t() (#14)
• add references to fuzzygrams in vignette("slabinterval") (#23)
• add examples with separate positioning of slab and interval (#27)
• add discussion of limitations of curvewise intervals to vignette("lineribbon") (#22)
• soft-deprecate usage of interval_size_range argument in docs (#35)
• initial versions of some cheat sheets

Bug fixes:

• add limited na.rm support to curve_interval() (#22)
• use analytical instead of numerical derivatives on scale transformations where possible, improving reliability.

New features and documentation:

• Add curve_interval() for generating curvewise (joint) intervals for curve boxplots (#22)
• Add vignette("lineribbon") describing geom_lineribbon(), stat_lineribbon(), stat_dist_lineribbon(), and curve_interval().

Bug fixes:

• Support dist aesthetics that are factors (#25)
• Fix slab drawing order for overlapping (ggridges-style) slabs (#30)
• Workaround for changes to {distributional} distribution functions until #31 is fixed.

• Support for distributional, including new examples in vignette("slabinterval") (#14).
• stat_dist_... geoms now calculate pdf and cdf columns to allow mashup geoms that involve both functions, such as Correll-style gradient plots combined with violins, as in Helske et al. (#11).
• stat_dist_... geoms should now work with gganimate (#15).
• Examples updated to fix errors introduced by broom::augment() defaulting to se_fit = FALSE.

• Initial split from tidybayes: ggdist now contains all stats/geoms from tidybayes (except deprecated ones), all support functions for stats/geoms (such as point_interval()), vignette("slabinterval"), and vignette("freq-uncertainty-vis"). Tidybayes will retain all other functions, and will re-export all ggdist functions for now.
• All stats and geoms now support automatic orientation determination. Thus, all h-suffix geoms are now deprecated. Those geoms have been left in tidybayes and give a deprecation warning when used; they cannot be used from ggdist directly.
• geom_interval(), geom_pointinterval(), and geom_lineribbon() no longer automatically set the ymin and ymax aesthetics if .lower or .upper are present in the data. This allows them to work better with automatic orientation detection (and was a bad feature to have existed in the first place anyway). The deprecated tidybayes::geom_intervalh() and tidybayes::geom_pointintervalh() still automatically set those aesthetics, since they are deprecated anyway (so supporting the old behavior is fine in these functions).
• geom_lineribbon()/stat_lineribbon() now supports a step argument for creating stepped lineribbons. H/T to Solomon Kurz for the suggestion.
• ggdist now has its own implementation of the scaled and shifted Student's t distribution (dstudent_t(), qstudent_t(), etc), since it is very useful for visualizing confidence distributions.
