 IPython's 'magic' functions
 ===========================
 
 The magic function system provides a series of functions which allow you to
 control the behavior of IPython itself, plus a lot of system-type
 features. There are two kinds of magics, line-oriented and cell-oriented.
 
 Line magics are prefixed with the % character and work much like OS
 command-line calls: they get as an argument the rest of the line, where
 arguments are passed without parentheses or quotes.  For example, this will
 time the given statement::
 
         %timeit range(1000)
 
 Cell magics are prefixed with a double %%, and they are functions that get as
 an argument not only the rest of the line, but also the lines below it in a
 separate argument.  These magics are called with two arguments: the rest of the
 call line and the body of the cell, consisting of the lines below the first.
 For example::
 
         %%timeit x = numpy.random.randn((100, 100))
         numpy.linalg.svd(x)
 
 will time the execution of the numpy svd routine, running the assignment of x
 as part of the setup phase, which is not timed.
 
 In a line-oriented client (the terminal or Qt console IPython), starting a new
 input with %% will automatically enter cell mode, and IPython will continue
 reading input until a blank line is given.  In the notebook, simply type the
 whole cell as one entity, but keep in mind that the %% escape can only be at
 the very start of the cell.
 
 NOTE: If you have 'automagic' enabled (via the command line option or with the
 %automagic function), you don't need to type in the % explicitly for line
 magics; cell magics always require an explicit '%%' escape.  By default,
 IPython ships with automagic on, so you should only rarely need the % escape.
 
 Example: typing '%cd mydir' (without the quotes) changes your working directory
 to 'mydir', if it exists.
 
 For a list of the available magic functions, use %lsmagic. For a description
 of any of them, type %magic_name?, e.g. '%cd?'.
 
 Currently the magic system has the following functions:""",

         and output look.  This makes it easy to copy and paste parts of a
         session into doctests.  It does so by:
 
         - Changing the prompts to the classic ``>>>`` ones.
         - Changing the exception reporting mode to 'Plain'.
         - Disabling pretty-printing of output.
 
         Note that IPython also supports the pasting of code snippets that have
         leading '>>>' and '...' prompts in them.  This means that you can paste
         doctests from files or docstrings (even if they have leading
         whitespace), and the code will execute correctly.  You can then use
         '%history -t' to see the translated history; this will give you the
         input after removal of all the leading prompts and whitespace, which
         can be pasted back into an editor.
 
         With these features, you can switch into this mode easily whenever you
         need to do testing and changes to doctests, without having to leave
         your existing IPython session.

             %gui         # disable all event loop integration
 
         WARNING:  after any of these has been called you can simply create
         an application object, but DO NOT start the event loop yourself, as
         we have already handled that.

 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
 
 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.
 
 
 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.
