- Support for 3-character hex color codes


Changed

- Parameters `labwidth` in `facetWrap()`, `xLabwidth, yLabwidth` in `facetGrid()`: the maximum label length is applied after splitting at `\n` separators, if present.

- `themeLight()` is now the default theme in `qqPlot()`.

- [**BREAKING**] For API deprecated in v4.0 the deprecation level raised to "Error".


Fixed

- waterfallPlot: faceting doesn't work without a measure mapping [[1152](https://github.com/JetBrains/lets-plot/issues/1152)].
- waterfallPlot: tooltips don't work with column names from original dataset [[1153](https://github.com/JetBrains/lets-plot/issues/1153)].
- Legend icon background is not transparent when `legendBackground` is set to "blank" in `theme` [[1167](https://github.com/JetBrains/lets-plot/issues/1167)].
- Unable to display or save graph when using geomPath [[1168](https://github.com/JetBrains/lets-plot/issues/1168)].
- Legend icon background should inherit the fill color of the plot panel (i.e. grey when `themeGrey()` is used).
- Vertex sampling uses different tolerances for objects within the same plot [[1174](https://github.com/JetBrains/lets-plot/issues/1174)].
- `samplingVertexVW()` doesn't work as expected [[1175](https://github.com/JetBrains/lets-plot/issues/1175)].
- `samplingVertexDP()` may break rings [[1176](https://github.com/JetBrains/lets-plot/issues/1176)].

- Offscreen cells are sometimes not rendered in JupyterLab.
- `legendJustification()` doesn't work if `legendPositionTop()` [[1031](https://github.com/JetBrains/lets-plot/issues/1031)].
- coordPolar: geomPoint tooltips should take in account point size [[1214](https://github.com/JetBrains/lets-plot/issues/1214)].

Changed

- The triangular point shape is now anchored to the data point via the centroid

Fixed

- ggsave (.svg) transforms geom_text integer to float [[626](https://github.com/JetBrains/lets-plot/issues/626)].
- Int DataFrame column names are being converted to float string representation [[901](https://github.com/JetBrains/lets-plot/issues/901)].
- `linetype` = 0 ("blank") should make lines invisible [[712](https://github.com/JetBrains/lets-plot/issues/712)].
- `geomDensity2D, geomDensity2DFilled`: support weight aesthetic [[791](https://github.com/JetBrains/lets-plot/issues/791)].
- Discrete axis labels unnecessarily rotate 90 degrees when applying coord system limits.
- Axis title via `labs()` breaks the date-time scale [[1113](https://github.com/JetBrains/lets-plot/issues/1113)].
- JavaFX IllegalArgumentException: Unsupported attribute `display` in Pane.
