This is a smaller patch release focussed on fixing regressions from 4.0.0 and polishing the recent features.

Bug fixes

• Fixed regression where geom_area() didn't draw panels with single groups when stat = "align" (@teunbrand, [#6680])
• Fixed regression where position_stack(vjust) was ignored when there are only single groups (#6692)
• Fixed bug where NA handling in geom_path() was ignoring panels (@teunbrand, [#6533])
• Fixed bug where stat_bin(boundary) was ignored (#6682).
• geom_text() and geom_label() accept expressions as the label aesthetic (@teunbrand, [#6638])
• Fixed regression where draw_key_rect() stopped using fill colours (@mitchelloharawild, [#6609]).
• Fixed regression where scale_{x,y}_*() threw an error when an expression object is set to labels argument (@yutannihilation, [#6617]).
• Fixed regression where the first (unnamed) argument to colour/fill scales was not passed as the name argument (@teunbrand, [#6623])
• Fixed issue where vectorised arrow()s caused errors in drawing the legend glyphs (@teunbrand, [#6594])
• Fixed regression where NULL-aesthetics contributed to plot labels too insistently. Now they contribute only as fallback labels (@teunbrand, [#6616])
• Fixed regression where empty arguments to colour/fill scale caused errors (@jmbarbone, [#6710])
• Fixed axis misplacement in coor_radial() when labels are blank (@teunbrand, [#6574])

Improvements

• Improved palette fallback mechanism in scales (@teunbrand, [#6669]).
• Allow stat in geom_hline, geom_vline, and geom_abline. (@sierrajohnson, [#6559])
• stat_boxplot() treats width as an optional aesthetic (@Yunuuuu, [#6575])
• The theme(panel.widths, panel.heights) setting attempts to preserve the plot's aspect ratio when only one of the two settings is given, and the plot has a single panel (@teunbrand, [#6701]).
• Logical values for the linetype aesthetic will be interpreted numerically, so that linetype = FALSE becomes 0/'blank' and linetype = TRUE becomes 1/'solid' (@teunbrand, [#6641])
• Out-of-bounds datapoints used as padding by stat_align() now get removed silently rather than verbosely (@teunbrand, [#6667])
