ggforce 0.4.2 (2024-02-19)

Moved to vctrs internally
Updated error messaging to use cli
geom_diagonal(), geom_diagonal_wide(), geom_parallel_sets(), and geom_sina() are now bidirectional in the style of ggplot2
geom_mark_*() now works correctly in the presence of NA values in x and y
The zoom, zoom.x, and zoom.y elements now uses proper registration of theme elements, inheriting from strip.background.
Fixed bug in geom_sina() when groups contained less than 3 points
Fixed bug in geom_parallel_sets() that erroneously removed grouping information in some configurations
Added jitter_y argument to geom_sina() to control whether y jittering is performed on integerish y values.
facet_zoom() now works with patchwork
Fix bug in geom_mark_ellipse() that caused wrong orientation of ellipses with groups of two.
gather_set_data() now supports tidyselect.
position_jitternormal() gains a seed argument in parallel to ggplot2::position_jitter()
geom_sina() now works when the group only have a single unique y value
facet_zoom() now works correctly with transformed scales
facet_wrap_paginate() now works correctly with dir = 'v'
facet_matrix() now supports a labeller
fix a bug in geom_parallel_sets_axes() that prevented coloring of axis fill
fix a bug in stat_circle() if the x and y aesthetics were inherited from the global mapping
facet_zoom() now works even when limits are set by the scales

Added facet_matrix() in order to facet different data columns into different rows and columns in a grid, in order to make e.g. scatterplot matrices and pairs plot
Added geom_autopoint() and position_auto() to jitter points based on the type of positional scales in the panel
Added geom_autohistogram() and geom_autodensity() for facilitating distribution plots along the diagonal in a facet_matrix() plot.
Added facet_row() and facet_col to have one-dimensional facet_wrap() with possibility of variable sizing.
Stats should now always keep the old group variable (potentially with something added), making them work with gganimate
Removed the Visual Guide vignette to reduce compilation time. See the website for an overview of all functionality with compiled examples (https://ggforce.data-imaginist.com)

Fixed a regression in geom_sina() where the computation would fail with a warning due to tolower() being masked (#134, #135).

Fixed a bug in the calculation of open and closed b-splines, where the interval would exceed the defined region and result in an out-of-bounds memory error

linear_trans for composing linear transformation using rotate, stretch, shear, reflect, and translate
facet_stereo added for creating stereographic projections
geom_voronoi_[tile|segment], geom_delaunay_[tile|segment|segment2], and stat_delvor_summary has been added for tesselation and triangulation.
geom_spiro has been added for drawing spirographs
Add geom_ellipse for drawing regular and superellipses
Add geom_regon for drawing regular polygons
Add geom_diagonal, geom_diagonal_wide and geom_parallel_sets for drawing parallel sets diagrams and other visualizations based on diagonals.
Add geom_shape for drawing polygons with rounded corners and expanded/contracted sides. geom_shape replaces all geom_polygon internally.
Added geom_bspline_closed to draw polygons defined as b-splines
Add geom_mark_[rect|circle|ellipse|hull] to encircle a group of points and optionally add textual annotation to it
Add position_jitternormal to jitter points based on a normal distribution (@andrewheiss)

facet_[wrap|grid]_paginate will now try to make panels on the last page the same size as on full pages (#7)
facet_zoom now gains xlim and ylim arguments to control zoom range directly
facet_zoom now gains zoom.data to control which data gets plotted in which panel
Slimmed down the dependencies for the package. plyr, lazyeval and dplyr has all been removed
Rewrite geom_sina to match geom_violin and allow for dodging
Add open/clamped option to `geom_bspline

Fix interpolation of x and y values in geom_link2 (@thomasp85 and @lepennec)
stat_link no longer replicates the group column
arcs and links no longer rename aesthetics when only one aesthetic is present (drop = FALSE)
stat_bezier0 and stat_bezier2 now return data in the expected format
Fix bug with n_pages due to internal changes in ggplot2
Fix bug in facet_zoom in combination with secondary y-axis where the space for the y-axis would become huge
Correctly detect and error out when scales and coords does not work with facet_zoom
The *2 versions of line geoms no longer adds an NA to guides.

Zoom indicator styling can now be specified separetely for x and y zoom using zoom.x and zoom.y in theme (inherits from zoom that inherits from strip.background)

Fix bug in facet_wrap_paginate that threw errors when using it with free scales (#19)
Fixes bug in facet_zoom where y-axis would be incorrectly displayed when zooming on both axes without splitting the view (#23)
Fixes bug in facet_zoom where scale expansion where not taken into account when drawing the indicator area (#22)
Fixes a bug in facet_zoom that would throw errors with layers not containing the column that is zoomed by (#21)

geom_edge_bundle has been renamed geom_bspline and lost the tension argument. True edge bundle functionality has been moved to ggraph

geom_arc / stat_arc for drawing circle segments
geom_edge_bundle / stat_edge_bundle for drawing edge bundles based on control points
geom_arc_bar /stat_arc_bar / stat_pie for drawing arcs and wedges with fill
geom_circle / stat_circle for drawing circles with radius based on coordinate system scale
power_trans for creating power transformations
radial_trans for creating transformation between radial and cartesian coordinates
trans_reverser for reversing a trans object
