  Development version
 =====================
 
 This document describes in-flight development work.
 
 Redesigned IPython notebook user interface
 ------------------------------------------
 
 (Add description & screenshots of the many changes to the notebook)
 
 Cell magics
 -----------
 
 IPython's ``%magic`` functions have been extended to let you change the meaning
 of a whole cell using the first line. For example, to time the execution of
 several statements::
 
     %%timeit x = 0   # setup
     for i in range(100000):
         x += i**2
 
 This is particularly useful to integrate code in another language, and cell
 magics already exist for shell scripts, Cython, R and Octave. Using ``%%script
 /usr/bin/foo``, you can run a cell in any interpreter that accepts code via
 stdin.
 
 Another handy cell magic makes it easy to write short text files: ``%%file
 ~/save/to/here.txt``.
 
 To allow these features, the API for magic functions has been refactored and
 made more powerful (:ghpull:`1732`).
 
 Interactive tab completion for the Qt console
 ---------------------------------------------
 
 (Add description & screenshots) (:ghpull:`1851`)
 
+
+Completer improvement
+---------------------
+
+One of the great feature of IPython is the ability to inspect live element and
+provide useful completion to the user, this one base of interactive
+exploration of data. To make this process even more user-friendly the completers
+of both the QTconsole and the Notebook has been reworked.
+
+The Qtconsole --gui-completion flag came with a new `ncurses` flavor, activated
+by default, which allows to cycle through the available completion by pressing
+tab, and to navigate the with the arrow keys.(:ghpull:`1851`)
+
+As part of the great refactoring of the notebook's JavaScript, the completer
+has been partially rewritten. Completions are now sourced both from object
+introspection and analyse of surrounding code, allowing to get a even limited
+completion on code not executed, or even while the kernel is busy.
+

 Other new features
 ------------------
 
 * **%install_ext**: A new magic function to install an IPython extension from
   a URL. E.g. ``%install_ext
   https://bitbucket.org/birkenfeld/ipython-physics/raw/default/physics.py``.
 
 * The ``%loadpy`` magic is no longer restricted to Python files, and has been
   renamed ``%load``. The old name remains as an alias.
 
 * New command line arguments will help external programs find IPython folders:
   ``ipython locate`` finds the user's IPython directory, and ``ipython locate
   profile foo`` finds the folder for the 'foo' profile (if it exists).
 
 * The :envvar:`IPYTHON_DIR` environment variable, introduced in the Great
   Reorganization of 0.11 and existing only in versions 0.11-0.13, has been
   deprecated. As described in :ghissue:`1167`, the complexity and confusion of
   migrating to this variable is not worth the aesthetic improvement. Please use
   the historical :envvar:`IPYTHONDIR` environment variable instead.
 
 * The default value of *interactivity* passed from
   :meth:`~IPython.core.interactiveshell.InteractiveShell.run_cell` to
   :meth:`~IPython.core.interactiveshell.InteractiveShell.run_ast_nodes`
   is now configurable.
 
 Backwards incompatible changes
 ------------------------------
 
 * The exception :exc:`IPython.core.error.TryNext` previously accepted
   arguments and keyword arguments to be passed to the next implementation
   of the hook. This feature was removed as it made error message propagation
   difficult and violated the principle of loose coupling.
