This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.

If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release).

7.x Series

IPython 7.8.0

IPython 7.8.0 contain a few bugfix and 2 new APIs:

  • Enable changing the font color for LaTeX rendering PR #11840

  • and Re-Expose some PDB API (see below)

Expose Pdb API

Expose the built-in pdb.Pdb API. Pdb constructor arguments are generically exposed, regardless of python version. Newly exposed arguments:

  • skip - Python 3.1+

  • nosiginnt - Python 3.2+

  • readrc - Python 3.6+

Try it out:

from IPython.terminal.debugger import TerminalPdb
pdb = TerminalPdb(skip=["skipthismodule"])

See PR #11840

IPython 7.7.0

IPython 7.7.0 contain multiple bug fixes and documentation updates; Here are a few of the outstanding issue fixed:

  • Fix a bug introduced in 7.6 where the %matplotlib magic would fail on previously acceptable arguments PR #11814.

  • Fix the manage location on freebsd PR #11808.

  • Fix error message about aliases after %reset call in ipykernel PR #11806

  • Fix Duplication completions in emacs PR #11803

We are planning to adopt NEP29 (still currently in draft) which may make this minor version of IPython the last one to support Python 3.5 and will make the code base more aggressive toward removing compatibility with older versions of Python.

GitHub now support to give only “Triage” permissions to users; if you’d like to help close stale issues and labels issues please reach to us with your GitHub Username and we’ll add you to the triage team. It is a great way to start contributing and a path toward getting commit rights.

IPython 7.6.1

IPython 7.6.1 contain a critical bugfix in the %timeit magic, which would crash on some inputs as a side effect of PR #11716. See PR #11812

IPython 7.6.0

IPython 7.6.0 contains a couple of bug fixes and number of small features additions as well as some compatibility with the current development version of Python 3.8.

  • Add a -l option to %psearch to list the available search types. PR #11672

  • Support PathLike for DisplayObject and Image. PR #11764

  • Configurability of timeout in the test suite for slow platforms. PR #11756

  • Accept any casing for matplotlib backend. PR #121748

  • Properly skip test that requires numpy to be installed PR #11723

  • More support for Python 3.8 and positional only arguments (pep570) PR #11720

  • Unicode names for the completion are loaded lazily on first use which should decrease startup time. PR #11693

  • Autoreload now update the types of reloaded objects; this for example allow pickling of reloaded objects. PR #11644

  • Fix a bug where %%time magic would suppress cell output. PR #11716

Prepare migration to pytest (instead of nose) for testing

Most of the work between 7.5 and 7.6 was to prepare the migration from our testing framework to pytest. Most of the test suite should now work by simply issuing pytest from the root of the repository.

The migration to pytest is just at its beginning. Many of our test still rely on IPython-specific plugins for nose using pytest (doctest using IPython syntax is one example of this where test appear as “passing”, while no code has been ran). Many test also need to be updated like yield-test to be properly parametrized tests.

Migration to pytest allowed me to discover a number of issues in our test suite; which was hiding a number of subtle issues – or not actually running some of the tests in our test suite – I have thus corrected many of those; like improperly closed resources; or used of deprecated features. I also made use of the pytest --durations=... to find some of our slowest test and speed them up (our test suite can now be up to 10% faster). Pytest as also a variety of plugins and flags which will make the code quality of IPython and the testing experience better.


We skipped the release of 7.6 at the end of May, but will attempt to get back on schedule. We are starting to think about making introducing backward incompatible change and start the 8.0 series.

Special Thanks to Gabriel (@gpotter2 on GitHub), who among other took care many of the remaining task for 7.4 and 7.5, like updating the website.

IPython 7.5.0

IPython 7.5.0 consist mostly of bug-fixes, and documentation updates, with one minor new feature. The Audio display element can now be assigned an element id when displayed in browser. See PR #11670

The major outstanding bug fix correct a change of behavior that was introduce in 7.4.0 where some cell magics would not be able to access or modify global scope when using the @needs_local_scope decorator. This was typically encountered with the %%time and %%timeit magics. See #11659 and PR #11698.

IPython 7.4.0

Unicode name completions

Previously, we provided completion for a unicode name with its relative symbol. With this, now IPython provides complete suggestions to unicode name symbols.

As on the PR, if user types \LAT<tab>, IPython provides a list of possible completions. In this case, it would be something like:


This help to type unicode character that do not have short latex aliases, and have long unicode names. for example Ͱ, \GREEK CAPITAL LETTER HETA.

This feature was contributed by Luciana Marques PR #11583.

Make audio normalization optional

Added ‘normalize’ argument to IPython.display.Audio. This argument applies when audio data is given as an array of samples. The default of normalize=True preserves prior behavior of normalizing the audio to the maximum possible range. Setting to False disables normalization.


  • Fix improper acceptation of return outside of functions. PR #11641.

  • Fixed PyQt 5.11 backwards incompatibility causing sip import failure. PR #11613.

  • Fix Bug where type? would crash IPython. PR #1608.

  • Allow to apply @needs_local_scope to cell magics for convenience. PR #11542.

IPython 7.3.0

IPython 7.3.0 bring several bug fixes and small improvements that you will described bellow.

The biggest change to this release is the implementation of the %conda and %pip magics, that will attempt to install packages in the current environment. You may still need to restart your interpreter or kernel for the change to be taken into account, but it should simplify installation of packages into remote environment. Installing using pip/conda from the command line is still the prefer method.

The %pip magic was already present, but was only printing a warning; now it will actually forward commands to pip.

Misc bug fixes and improvements:

  • Compatibility with Python 3.8.

  • Do not expand shell variable in execution magics, and added the no_var_expand decorator for magic requiring a similar functionality PR #11516

  • Add %pip and %conda magic PR #11524

  • Re-initialize posix aliases after a %reset PR #11528

  • Allow the IPython command line to run *.ipynb files PR #11529

IPython 7.2.0

IPython 7.2.0 brings minor bugfixes, improvements, and new configuration options:

  • Fix a bug preventing PySide2 GUI integration from working PR #11464

  • Run CI on Mac OS ! PR #11471

  • Fix IPython “Demo” mode. PR #11498

  • Fix %run magic with path in name PR #11499

  • Fix: add CWD to sys.path after stdlib PR #11502

  • Better rendering of signatures, especially long ones. PR #11505

  • Re-enable jedi by default if it’s installed PR #11506

  • Add New minimal exception reporting mode (useful for educational purpose). See PR #11509

Added ability to show subclasses when using pinfo and other utilities

When using ?/?? on a class, IPython will now list the first 10 subclasses.

Special Thanks to Chris Mentzel of the Moore Foundation for this feature. Chris is one of the people who played a critical role in IPython/Jupyter getting funding.

We are grateful for all the help Chris has given us over the years, and we’re now proud to have code contributed by Chris in IPython.

OSMagics.cd_force_quiet configuration option

You can set this option to force the %cd magic to behave as if -q was passed:

In [1]: cd /

In [2]: %config OSMagics.cd_force_quiet = True

In [3]: cd /tmp

In [4]:

See PR #11491

In vi editing mode, whether the prompt includes the current vi mode can now be configured

Set the TerminalInteractiveShell.prompt_includes_vi_mode to a boolean value (default: True) to control this feature. See PR #11492

IPython 7.1.0

IPython 7.1.0 is the first minor release after 7.0.0 and mostly brings fixes to new features, internal refactoring, and fixes for regressions that happened during the 6.x->7.x transition. It also brings Compatibility with Python 3.7.1, as we’re unwillingly relying on a bug in CPython.

New Core Dev:

  • We welcome Jonathan Slenders to the commiters. Jonathan has done a fantastic work on prompt_toolkit, and we’d like to recognise his impact by giving him commit rights. #11397

Notable Changes

  • Major update of “latex to unicode” tab completion map (see below)

Notable New Features:

  • Restore functionality and documentation of the sphinx directive, which is now stricter (fail on error by daefault), has new configuration options, has a brand new documentation page IPython Sphinx Directive (which needs some cleanup). It is also now tested so we hope to have less regressions. PR #11402

  • IPython.display.Video now supports width and height arguments, allowing a custom width and height to be set instead of using the video’s width and height. PR #11353

  • Warn when using HTML('<iframe>') instead of IFrame PR #11350

  • Allow Dynamic switching of editing mode between vi/emacs and show normal/input mode in prompt when using vi. PR #11390. Use %config TerminalInteractiveShell.editing_mode = 'vi' or %config TerminalInteractiveShell.editing_mode = 'emacs' to dynamically switch between modes.

Notable Fixes:

  • Fix entering of multi-line blocks in terminal IPython, and various crashes in the new input transformation machinery PR #11354, PR #11356, PR #11358. These also fix a Compatibility bug with Python 3.7.1.

  • Fix moving through generator stack in ipdb PR #11266

  • %Magic command arguments now support quoting. PR #11330

  • Re-add rprint and rprinte aliases. PR #11331

  • Remove implicit dependency on ipython_genutils PR #11317

  • Make nonlocal raise SyntaxError instead of silently failing in async mode. PR #11382

  • Fix mishandling of magics and = ! assignment just after a dedent in nested code blocks PR #11418

  • Fix instructions for custom shortcuts PR #11426

Notable Internals improvements:

  • Use of os.scandir (Python 3 only) to speed up some file system operations. PR #11365

  • use perf_counter instead of clock for more precise timing results with %time PR #11376

Many thanks to all the contributors and in particular to bartskowron and tonyfast who handled some pretty complicated bugs in the input machinery. We had a number of first time contributors and maybe hacktoberfest participants that made significant contributions and helped us free some time to focus on more complicated bugs.

Unicode Completion update

In IPython 7.1 the Unicode completion map has been updated and synchronized with the Julia language.

Added and removed character characters:

\jmath (ȷ), \\underleftrightarrow (U+034D, combining) have been added, while \\textasciicaron have been removed

Some sequences have seen their prefix removed:

  • 6 characters \text...<tab> should now be inputed with \...<tab> directly,

  • 45 characters \Elz...<tab> should now be inputed with \...<tab> directly,

  • 65 characters \B...<tab> should now be inputed with \...<tab> directly,

  • 450 characters \m...<tab> should now be inputed with \...<tab> directly,

Some sequences have seen their prefix shortened:

  • 5 characters \mitBbb...<tab> should now be inputed with \bbi...<tab> directly,

  • 52 characters \mit...<tab> should now be inputed with \i...<tab> directly,

  • 216 characters \mbfit...<tab> should now be inputed with \bi...<tab> directly,

  • 222 characters \mbf...<tab> should now be inputed with \b...<tab> directly,

A couple of characters had their sequence simplified:

  • ð, type \dh<tab>, instead of \eth<tab>

  • ħ, type \hbar<tab>, instead of \Elzxh<tab>

  • ɸ, type \ltphi<tab>, instead of \textphi<tab>

  • ϴ, type \varTheta<tab>, instead of \textTheta<tab>

  • , type \eulermascheroni<tab>, instead of \Eulerconst<tab>

  • , type \planck<tab>, instead of \Planckconst<tab>

  • U+0336 (COMBINING LONG STROKE OVERLAY), type \strike<tab>, instead of \Elzbar<tab>.

A couple of sequences have been updated:

  • \varepsilon now gives ɛ (GREEK SMALL LETTER EPSILON) instead of ε (GREEK LUNATE EPSILON SYMBOL),

  • \underbar now gives U+0331 (COMBINING MACRON BELOW) instead of U+0332 (COMBINING LOW LINE).

IPython 7.0.0

Released Thursday September 27th, 2018

IPython 7 includes major feature improvements. 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, but there are still many PRs that required manual work. This is an area of the project where you can easily contribute by looking for PRs that still need manual backport

The 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 running:

pip install ipython --upgrade

Or, if you have conda installed:

conda install ipython

Prompt Toolkit 2.0

IPython 7.0+ now uses prompt_toolkit 2.0. If you still need to use an earlier prompt_toolkit version, you may need to pin IPython to <7.0.

Autowait: Asynchronous REPL

Staring with IPython 7.0 on Python 3.6+, IPython can automatically await top level code. You should not need to access an event loop or runner yourself. To learn more, read the Asynchronous in REPL: Autoawait section of our docs, see PR #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('')

In [2]: response = await result
<pause for a few 100s ms>

In [3]: await response.json()
{'authorizations_url': '',
 'code_search_url': '{query}{&page,per_page,sort,order}',


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 Asynchronous in REPL: Autoawait for more information.

Asynchronous code in a Notebook interface or any other frontend using the Jupyter Protocol will require further updates to 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 %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 an event loop is specified.

Effects on Magics

Some magics will not work with async until they’re updated. Contributions welcome.

Expected Future changes

We expect more internal but public IPython functions to become async, and will likely end up having a persistent event loop while IPython is running.


This release took more than a year in the making. The code was rebased a number of times; 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-cases: dalejung, danielballan, ellisonbg, fperez, gnestor, minrk, njsmith, pganssle, tacaswell, takluyver , vidartf … And many others.

Autoreload Improvement

The magic %autoreload 2 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 is saved on disk.

# notebook

from mymodule import MyClass
first = MyClass(5)
# mymodule/

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


The autoindent feature that was deprecated in 5.x was re-enabled and un-deprecated in PR #11257

Make %run -n -i ... work correctly. Earlier, if %run was passed both arguments, -n would be silently ignored. See PR #10308

The %%script (as well as %%bash, %%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.


A couple of unused functions and methods have been deprecated and will be removed in future versions:



Backwards incompatible changes

  • The API for transforming input before it is parsed as Python code has been completely redesigned: any custom input transformations will need to be rewritten. See Custom input transformation for details of the new API.
