+* New roxygen tag `@aesthetics` that takes a Geom, Stat or Position class and
+  generates an 'Aesthetics' section.
 * Facet gains a new method `setup_panel_params` to interact with the
   panel_params setted by Coord object (@Yunuuuu, #6397, #6380)
 * `position_fill()` avoids stacking observations of zero (@teunbrand, #6338)
