+* What's changed since window-numbering
+This package brings a lot of additions to the old window-numbering:
+
+- Number sets across multiple frames, giving a smoother experience of
+  multi-screen Emacs
+- 3 possible scopes: frame-local, visible frames or all frames
+- =get-window-by-number= public function, needed in Spacemacs and for future
+  developments.
+- Unlimited window numbers
+- =select-window-by-number= can now be used interactively to select a window
+  using prefix arg or =read-from-minibuffer=, allowing the selection of an
+  unlimited number.
+- Ignore buffers by name
+- =;;;###autoload= all functions that should have public visibility
+- Improved =customize= integration
+- Removed =window-numbering-before-assign-hook=, which just duplicated
+ =window-numbering-assign-func= in a more complicated fashion
+- New default key bindings under the ~C-x w~ prefix, to be compliant with Emacs
+  key bindings conventions and native Emacs key bindings
+- =winum-set-keymap-prefix= helper function to change the prefix more easily
+- More detailed README.org
+- Improved docstrings
+- Simplified implementation for better readability
+

 * Future developments
 - send buffer to numbered window
-
   Send current window's buffer to window N. With prefix argument focus will
   follow.
 
-  Also provide a `winum-send-buffer-to-window-by-number` function (and find
-  shorter names).
-
 - swap buffer with numbered window
-
   Same as previous, but will swap buffers instead of just sending them.
 
-  Also provide a `winum-swap-buffre-with-window-by-number` function (and find
-  better names).
-
 - Evilify
-
   Adapt the package to the famous `evil-mode` and use a leader key.
 
 - Override native =other-window= (~C-x o~) to use window numbers
 
 - Autocomplete read-from-minibuffer

-  mentionned points :)
