 ============
  7.x Series
 ============
 
 .. _whatsnew700:
 
 IPython 7.0.0
 =============
 
 Released Thursday September 27th, 2018
 
 IPython 7 include major features improvement as you can read in the following
 changelog. This is also the second major version of IPython to support only
 Python 3 – starting at Python 3.4. Python 2 is still community supported
 on the bugfix only 5.x branch, but we remind you that Python 2 "end of life"
 is on Jan 1st 2020.
 
 We were able to backport bug fixes to the 5.x branch thanks to our backport bot which
 backported more than `70 Pull-Requests
 <https://github.com/ipython/ipython/pulls?page=3&q=is%3Apr+sort%3Aupdated-desc+author%3Aapp%2Fmeeseeksdev++5.x&utf8=%E2%9C%93>`_, but there are still many PRs that required manually work, and this is an area of the project were you can easily contribute by looking for `PRs still needed backport <https://github.com/ipython/ipython/issues?q=label%3A%22Still+Needs+Manual+Backport%22+is%3Aclosed+sort%3Aupdated-desc>`_
 
 IPython 6.x branch will likely not see any further release unless critical
 bugs are found.
 
 Make sure you have pip > 9.0 before upgrading. You should be able to update by simply running
 
 .. code::
 
     pip install ipython --upgrade
 
 .. only:: ipydev
 
   If you are trying to install or update an ``alpha``, ``beta``, or ``rc``
   version, use pip ``--pre`` flag.
 
   .. code::
 
       pip install ipython --upgrade --pre
 
 
 Or if you have conda installed: 
 
 .. code::
    
    conda install ipython
 
 
 
 Prompt Toolkit 2.0
 ------------------
 
 IPython 7.0+ now uses ``prompt_toolkit 2.0``, if you still need to use earlier
 ``prompt_toolkit`` version you may need to pin IPython to ``<7.0``.
 
 Autowait: Asynchronous REPL
 ---------------------------
 
 Staring with IPython 7.0 and on Python 3.6+, IPython can automatically await
 code at top level, you should not need to access an event loop or runner
 yourself. To know more read the :ref:`autoawait` section of our docs, see
 :ghpull:`11265` or try the following code::
 
     Python 3.6.0
     Type 'copyright', 'credits' or 'license' for more information
     IPython 7.0.0 -- An enhanced Interactive Python. Type '?' for help.
 
     In [1]: import aiohttp
        ...: result = aiohttp.get('https://api.github.com')
 
     In [2]: response = await result
     <pause for a few 100s ms>
 
     In [3]: await response.json()
     Out[3]:
     {'authorizations_url': 'https://api.github.com/authorizations',
      'code_search_url': 'https://api.github.com/search/code?q={query}{&page,per_page,sort,order}',
     ...
     }
 
 .. note::
 
    Async integration is experimental code, behavior may change or be removed
    between Python and IPython versions without warnings.
 
 Integration is by default with `asyncio`, but other libraries can be configured,
 like ``curio`` or ``trio``, to improve concurrency in the REPL::
 
     In [1]: %autoawait trio
 
     In [2]: import trio
 
     In [3]: async def child(i):
        ...:     print("   child %s goes to sleep"%i)
        ...:     await trio.sleep(2)
        ...:     print("   child %s wakes up"%i)
 
     In [4]: print('parent start')
        ...: async with trio.open_nursery() as n:
        ...:     for i in range(3):
        ...:         n.spawn(child, i)
        ...: print('parent end')
     parent start
        child 2 goes to sleep
        child 0 goes to sleep
        child 1 goes to sleep
        <about 2 seconds pause>
        child 2 wakes up
        child 1 wakes up
        child 0 wakes up
     parent end
 
 See :ref:`autoawait` for more information.
 
 
 Asynchronous code in a Notebook interface or any other frontend using the
 Jupyter Protocol will need further updates of the IPykernel package.
 
 Non-Asynchronous code
 ~~~~~~~~~~~~~~~~~~~~~
 
 As the internal API of IPython is now asynchronous, IPython needs to run under
 an event loop. In order to allow many workflows, (like using the :magic:`%run`
 magic, or copy_pasting code that explicitly starts/stop event loop), when
 top-level code is detected as not being asynchronous, IPython code is advanced
 via a pseudo-synchronous runner, and may not advance pending tasks.
 
 Change to Nested Embed
 ~~~~~~~~~~~~~~~~~~~~~~
 
 The introduction of the ability to run async code had some effect on the
 ``IPython.embed()`` API. By default embed will not allow you to run asynchronous
 code unless a event loop is specified.
 
 Effects on Magics
 ~~~~~~~~~~~~~~~~~
 
 Some magics will not work with Async, and will need updates. Contribution
 welcome.
 
 Expected Future changes
 ~~~~~~~~~~~~~~~~~~~~~~~
 
 We expect more internal but public IPython function to become ``async``, and
 will likely end up having a persisting event loop while IPython is running.
 
 Thanks
 ~~~~~~
 
 This took more than a year in the making, and the code was rebased a number of
 time leading to commit authorship that may have been lost in the final
 Pull-Request. Huge thanks to many people for contribution, discussion, code,
 documentation, use-case: dalejung, danielballan, ellisonbg, fperez, gnestor,
 minrk, njsmith, pganssle, tacaswell, takluyver , vidartf ... And many others.
 
 
 Autoreload Improvement
 ----------------------
 
 The magic :magic:`%autoreload 2 <autoreload>` now captures new methods added to
 classes. Earlier, only methods existing as of the initial import were being
 tracked and updated.  
 
 This new feature helps dual environment development - Jupyter+IDE - where the
 code gradually moves from notebook cells to package files, as it gets
 structured.
 
 **Example**: An instance of the class ``MyClass`` will be able to access the
 method ``cube()`` after it is uncommented and the file ``file1.py`` saved on
 disk.
 
 
 ..code::
 
    # notebook
 
    from mymodule import MyClass
    first = MyClass(5)
 
 .. code::
 
    # mymodule/file1.py
 
    class MyClass:
 
        def __init__(self, a=10):
            self.a = a
 
        def square(self):
            print('compute square')
            return self.a*self.a
 
        # def cube(self):
        #     print('compute cube')
        #     return self.a*self.a*self.a
 
 
 
 
 Misc
 ----
 
 The autoindent feature that was deprecated in 5.x was re-enabled and
 un-deprecated in :ghpull:`11257`
 
 Make :magic:`%run -n -i ... <run>` work correctly. Earlier, if :magic:`%run` was
 passed both arguments, ``-n`` would be silently ignored. See :ghpull:`10308`
 
 
-The :cellmagic:`%%script`` (as well as :cellmagic:`%%bash``,
-:cellmagic:`%%ruby``... ) cell magics now raise by default if the return code of
+The :cellmagic:`%%script` (as well as :cellmagic:`%%bash`,
+:cellmagic:`%%ruby`... ) cell magics now raise by default if the return code of
 the given code is non-zero (thus halting execution of further cells in a
 notebook). The behavior can be disable by passing the ``--no-raise-error`` flag.
 
 
 Deprecations
 ------------
 
 A couple of unused function and methods have been deprecated and will be removed
 in future versions:
 
   - ``IPython.utils.io.raw_print_err``
   - ``IPython.utils.io.raw_print``
 
   
 Backwards incompatible changes

 * The API for transforming input before it is parsed as Python code has been
   completely redesigned, and any custom input transformations will need to be
   rewritten. See :doc:`/config/inputtransforms` for details of the new API.
