[4.8.0] - 2025-11-05

Added

• Geometries:

• geom_pointdensity() [#1370].

  See: example notebook.

• Geoms with 1-to-1 statistics (such as geom_qq(), geom_sina()) preserve the mapping to original data after statistical transformation.

  See: example notebook.

• geom_histogram(): custom bin bounds (parameter breaks) [#1382].

  See: example notebook.

• Plot Layout:

• The legend automatically wraps to prevent overlap - up to 15 rows for vertical legends and 5 columns for horizontal ones [#1235].

  See: example notebook.

• gggrid(): support for shared legends (parameter guides).

  See: example notebook.

• Plot Theme:

• flavor_standard() sets the theme's default color scheme [#1277].
  Use to override other flavors or make defaults explicit.

  See: example notebook.

• theme_gray() as an alias for theme_grey().

• legend_justification parameter of theme() accepts additional string values: 'left', 'right', 'top', and 'bottom'.

  See: example notebook.

• Support for inward axis ticks.

  See: example notebook.

• Markdown:

• Support for target attribute for links.

• Links now open in a new tab by default [#1397].

• ggtb(): size_zoomin and size_basis parameters for geometry scaling [#1369].

See: example notebook.

Changed

• [BREAKING] Explicit group aesthetic now overrides default grouping behavior instead of combining with it [#1401].

See: example notebook.

[!IMPORTANT] Previously, setting group='variable' would group by both the explicit variable AND any discrete aesthetics (color, shape, etc.). \ Now it groups ONLY by the explicit variable, matching ggplot2 behavior. \ Use group=[var1, var2, ...] to group by multiple variables explicitly, \ and group=[] to disable any grouping.

• Missing values in geom_line(), geom_path(), geom_ribbon(), and geom_area() create gaps in geometries instead of being interpolated over [#818], [#1406].

See: example notebook.

• theme: the exponent_format default value changed to 'pow' - superscript powers of 10 (was e-notation).

• The multi-layer line plot now shows tooltips for each series simultaneously, in the same way that a single-layer plot with color mapped to series does.

Fixed

• geom_pie on geospatioal plot with map_join failes to render without explicit group aesthetic.
• geom_density2d: NullPointerException when weight aesthetic contains None values [#1399].
• Tooltip shows duplicate lines when as_discrete is applied twice to the same var [#1400].
• geom_sina: incorrect shape in legend [#1403].
• geom_density2d: Incorrect processing of weighted statistics when None value occurs in the x or y column.
• facet_wrap: indescriptive error when the specified facet variable is not present in the dataset [#1409].
• Integer numbers in facet strip titles are displayed as float [#1386].
• Error when using scale_identity(aesthetic="shape") [#1212].
• ggsave: theme option face="italic" doesn't work [#1391].
• Fail early if string format is incorrect [#1410].
