 IPython provides a rich toolkit to help you make the most out of using Python
 interactively.  Its main components are:
 
 * A powerful interactive Python shell
 * A `Jupyter <http://jupyter.org/>`_ kernel to work with Python code in Jupyter
   notebooks and other interactive frontends.
 
 The enhanced interactive Python shells have the following main features:
 
 * Comprehensive object introspection.
 
 * Input history, persistent across sessions.
 
 * Caching of output results during a session with automatically generated
   references.
 
 * Extensible tab completion, with support by default for completion of python
   variables and keywords, filenames and function keywords.
 
 * Extensible system of 'magic' commands for controlling the environment and
   performing many tasks related either to IPython or the operating system.
 
 * A rich configuration system with easy switching between different setups
   (simpler than changing $PYTHONSTARTUP environment variables every time).
 
 * Session logging and reloading.
 
 * Extensible syntax processing for special purpose situations.
 
 * Access to the system shell with user-extensible alias system.
 
 * Easily embeddable in other Python programs and GUIs.
 
 * Integrated access to the pdb debugger and the Python profiler.
 
 The latest development version is always available from IPython's `GitHub
 site <http://github.com/ipython>`_.

 IPython 6.0
 ===========
 
 Released .... ...., 2017
 
 IPython 6 feature a major improvement in the completion machinery which is now
 capable of completing non-executed code. It is also the first version of IPython
 to stop compatibility with Python 2, which is still supported on the bugfix only
 5.x branch. Read below to have a non-exhaustive list of new features.
 
 Make sure you have pip > 9.0 before upgrading.
 You should be able to update by using:
 
 .. code::
 
     pip install ipython --upgrade
 
 
 .. note::
 
     If your pip version is greater of equal to pip 9.0.1 you will automatically get
     the most recent version of IPython compatible with your system. THat is to day
     on Python 2 you will get the latest IPython 5.x bugfix, while in Python 3
     you will get the latest 6.x stable version.
 
 New completion API and Interface
 --------------------------------
 
 The completer Completion API has seen an overhaul, and the new completer have
 plenty of improvement both from the end users of terminal IPython or for
 consumers of the API.
 
 This new API is capable of pulling completions from :any:`jedi`, thus allowing
 type inference on non-executed code. If :any:`jedi` is installed completion like
 the following are now becoming possible without code evaluation:
 
     >>> data = ['Number of users', 123_456]
     ... data[0].<tab>
 
 That is to say, IPython is now capable of inferring that `data[0]` is a string,
 and will suggest completions like `.capitalize`. The completion power of IPython
 will increase with new Jedi releases, and a number of bugs and more completions
 are already available on development version of :any:`jedi` if you are curious.
 
 With the help of prompt toolkit, types of completions can be shown in the
 completer interface:
 
 .. image:: ../_images/jedi_type_inference_60.png
     :alt: Jedi showing ability to do type inference
     :align: center
     :width: 400px
     :target: ../_images/jedi_type_inference_60.png
 
 The appearance of the completer is controlled by the
 ``c.TerminalInteractiveShell.display_completions`` option that will show the
 type differently depending on the value among ``'column'``, ``'multicolumn'``
 and ``'readlinelike'``
 
 The use of Jedi also full fill a number of request and fix a number of bugs
 like case insensitive completion, completion after division operator: See
 :ghpull:`10182`.
 
 Extra patches and updates will be needed to the :mod:`ipykernel` package for
 this feature to be available to other clients like jupyter Notebook, Lab,
 Nteract, Hydrogen...
 
 The use of Jedi can is barely noticeable on recent enough machines, but can be
 feel on older ones,  in cases were Jedi behavior need to be adjusted, the amount
 of time given to Jedi to compute type inference can be adjusted with
 ``c.IPCompleter.jedi_compute_type_timeout``, with object whose type were not
 inferred will be shown as ``<unknown>``. Jedi can also be completely deactivated
 by using the ``c.Completer.use_jedi=False`` option.
 
 
 The old ``Completer.complete()`` API is waiting deprecation and should be
 replaced replaced by ``Completer.completions()`` in a near future. Feedback on
 the current state of the API and suggestions welcome.
 
 Python 3 only codebase
 ----------------------
 
 One of the large challenges in IPython 6.0 has been the adoption of a pure
 Python 3 code base, which lead us to great length to upstream patches in pip,
 pypi and warehouse to make sure Python 2 system still upgrade to the latest
 compatible Python version compatible.
 
 We remind our Python 2 users that IPython 5 is still compatible with Python 2.7,
 still maintained and get regular releases. Using pip 9+, upgrading IPython will
 automatically upgrade to the latest version compatible with your system.
 
 .. warning::
 
   If you are on a system using an older verison of pip on Python 2, pip may
   still install IPython 6.0 on your system, and IPython will refuse to start.
   You can fix this by ugrading pip, and reinstalling ipython, or forcing pip to
   install an earlier version: ``pip install 'ipython<6'``
 
 The ability to use only Python 3 on the code base of IPython has bring a number
 of advantage. Most of the newly written code make use of `optional function type
 anotation <https://www.python.org/dev/peps/pep-0484/>`_ leading to clearer code
 and better documentation.
 
 The total size of the repository has also for a first time between releases
 (excluding the big split for 4.0) decreased by about 1500 lines, potentially
 quite a bit more codewide as some documents like this one are append only and
 are about 300 lines long.
 
 The removal as of Python2/Python3 shim layer has made the code quite clearer and
 more idiomatic in a number of location, and much friendlier to work with and
 understand. We hope to further embrace Python 3 capability in the next release
 cycle and introduce more of the Python 3 only idioms (yield from, kwarg only,
 general unpacking) in the code base of IPython, and see if we can take advantage
 of these as well to improve user experience with better error messages and
 hints.
 
 
 Configurable TerminalInteractiveShell, readline interface
 ---------------------------------------------------------
 
 IPython gained a new ``c.TerminalIPythonApp.interactive_shell_class`` option
 that allow to customize the class used to start the terminal frontend. This
 should allow user to use custom interfaces, like reviving the former readline
 interface which is now a separate package not actively maintained by the core
 team. See the project to bring back the readline interface: `rlipython
 <https://github.com/ipython/rlipython>`_.
 
 This change will be backported to the IPython 5.x series.
 
 
 Miscs improvements
 ------------------
 
 
 - The :cellmagic:`capture` magic can now capture the result of a cell (from an
   expression on the last line), as well as printed and displayed output.
   :ghpull:`9851`.
 
 - Pressing Ctrl-Z in the terminal debugger now suspends IPython, as it already
   does in the main terminal prompt.
 
 - autoreload can now reload ``Enum``. See :ghissue:`10232` and :ghpull:`10316`
 
 - IPython.display has gained a :any:`GeoJSON <IPython.display.GeoJSON>` object.
   :ghpull:`10288` and :ghpull:`10253`

 Functions Deprecated in 6.x Development cycle
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 - Loading extensions from ``ipython_extension_dir`` print a warning that this
   location is pending deprecation. This should only affect users still having
   extensions installed with ``%install_ext`` which has been deprecated since
   IPython 4.0, and removed in 5.0. Extensions still present in
   ``ipython_extension_dir`` may shadow more recently installed versions using
   pip. It is thus recommended to clean ``ipython_extension_dir`` of any
   extension now available as a package.
 
 
 - ``IPython.utils.warn`` was deprecated in IPython 4.0, and has now been removed.
   instead of ``IPython.utils.warn`` inbuilt :any:`warnings` module is used.
 
 
 - The function `IPython.core.oinspect.py:call_tip` is unused, was marked as
   Deprecated (raising a Deprecation Warning) and marked for later removal
   :ghpull:`10104`
 
 Backwards incompatible changes
 ------------------------------
 
 Functions Removed in 6.x Development cycle
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 The following functions have been removed in the
 development cycle marked for Milestone 6.0.
 
 - ``IPython/utils/process.py`` - ``is_cmd_found``
 - ``IPython/utils/process.py`` - ``pycmd2argv``
 
 - The `--deep-reload` flag and the corresponding options to inject `dreload` or
   `reload` into the interactive namespace have been removed. You have to
   explicitly import `reload` from `IPython.lib.deepreload` to use it.
 
 - the :magic:`profile` used to print current IPython profile in use, and which
   was deprecated in IPython 2.0 does now raise a `DeprecationWarning` error when
   used. It is often confused with the :magic:`prun` and the deprecation remove
   should free up the ``profile`` name in future versions.
