+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)
-* 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)
 * 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).
-* 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)
 * Fixed regression where the first (unnamed) argument to colour/fill scales was 
   not passed as the `name` argument (@teunbrand, #6623)

-This is a major release of ggplot2. Among other things it includes an adaption

+This is a patch release fixing a range of regressions reported after the 4.0.0
