ggforce 0.5.0

• Fixed a bug that would cause reordering of data in some geoms (#314)
• The concaveman package is no longer a dependency for geom_mark_hull() (#308)
• Setting both label and description to NA will now turn off label drawing for
  that mark completely while still drawing the mark
• Fix a bug in geom_mark_rect() where the mark would not be shown in all
  panels (#307)
• Fixed a bug in the geom_mark_*() geoms where having NA values in the
  filter aesthetic would lead to weird errors. NA is now treated as FALSE
  (#306)
• shapeGrob() is now exported for use by other packages (#303)
• Fix a bug in geom_autohistogram() that prevented it to be used with
  continuous data (#297)
• facet_zoom() now throws a better error when used with coord_flip() (#143)
• You can now use "inherit", "inherit_fill", and "inherit_col" for the
  styling of the label box and connector in the geom_mark_*() family of geoms
  (#240)
• Prepare for upcoming changes in ggplot2
