 ** What's new
+*** Local map face
+- The face =which-key-local-map-description-face= is now available. This face
+  will be applied to any commands that are found using =(current-local-map)=
+  (commands defined for the major mode are usually here). This allows you to
+  distinguish between local and global bindings visually. See [[#faces][Face Customization]]
+  for more information.
 *** Paging
 - Paging is now turned on by default, using any prefix plus =C-h= (this doesn't
   affect key sequences that start with =C-h= and will not override any key

+The faces that which-key uses are

+The last two deserve some explanation. A command lives in one of many possible
+keymaps. You can distinguish between local maps, which depend on the buffer you
+are in, which modes are active, etc., and the global map which applies
+everywhere. It might be useful for you to distinguish between the two. One way
+to do this is to remove the default face from
+=which-key-command-description-face= like this
+
+#+BEGIN_SRC emacs-lisp
+  (set-face-attribute 'which-key-command-description-face nil :inherit nil)
+#+END_SRC
+
+another is to make the local map keys appear in bold
+
+#+BEGIN_SRC emacs-lisp
+  (set-face-attribute 'which-key-local-map-description-face nil :weight 'bold)
+#+END_SRC
+
+You can also use =M-x customize-face= to customize any of the above faces to
+your liking.
