  8.x Series
 ============
 .. _version 8.27:
 
 IPython 8.27
 ============
 
 New release of IPython after a month off (not enough changes). We can see a few
 important changes for this release.
 
  - autocall was beeing  call getitem, :ghpull:`14486`
  - Only copy files in startup dir if we just created it. :ghpull:`14497`
  - Fix some tests on Python 3.13 RC1 :ghpull:`14504`; this one I guess make this
    the first IPython release officially compatible with Python 3.13; you will
    need the most recent ``executing`` and ``stack_data``, we won't pin to avoid
    forcing user of older Python version to upgrade.

 Many thanks to `@Kleirre <https://github.com/Kleirre>`__ our June intern for
 doing her first contribution to open source, doing the releases notes and
 release. I guess you didn't even notice it was not me who released :-). I wish
 her all the best in her future endeavor and look forward for her work in
 astrophysics.

 .. _version 8.25:
 
 IPython 8.25
 ============
 
 Mostly internal changes for this end of may release of IPython.
 
 We'll count about a dozen PRs for this moth, with small bugfixes related to
 matplotlib fixes.
 
 Of notable interest,
 
  - :ghpull:`14426` replaces the unicode micro symbol with greek letter mu,
    visually identical but should fix nfkc normalisations issues.
 
  - :ghpull:`14444` introduces ``intersphinx_registry``  as a new dependency
    which is recommended only to build documentation.

 .. _version 8.24:
 
 IPython 8.24
 ============
 
 Back on regular release schedule, as usual month releases are relatively tiny.
 
 The biggest change is the move of the matplotlib backend handling from IPython
 to matplotlib. :ghpull:`14371` :ghpull:`14403`.
 
 We will note:
 
  - pytest 8 compatibility :ghpull:`14413`
  - ``typing-extension`` now needs 4.6 or newer. It was already the case, but not
    explicated. :ghpull:`14380`
  - Attempt to speed running code under debugger in some cases. :ghpull:`14386`
    :ghpull:`14418`.
  - Multiple fixes to documentation for ipyparallel, simple_prompt and emacs
    :ghpull:`14384` :ghpull:`14404` :ghpull:`14407`
  - Maintenance and cleanup of debugger :ghpull:`14387` :ghpull:`14393`

 .. _version 8.23:
 
 IPython 8.23
 ============
 
 Super tiny release of IPython on Sunday – a bit later than usual, which is also
 `🏳️‍⚧️ International Transgender Day of Visibility🏳️‍⚧️
 <https://en.wikipedia.org/wiki/International_Transgender_Day_of_Visibility>`_ –
 so a though for you on this day, you matter and you are valid [1]_.
 
 This is a minuscule release with only 5 Pull requests.
 
 Main change is :ghpull:`14357` which improve inference from return type
 annotations in completer and the introduction of the optional target
 ``ipython[matplotlib]`` to explicitly request the matplotlib optional
 dependencies.

 .. _version 8.22:
 
 IPython 8.22, 8.22.1 and 8.22.2
 ===============================
 
 Quick release of IPython for this short month of February, with quite a bit of
 activity with more than 15 PRs.
 
 I am not going to details all the changes, but among other we have :
 
  - More compatibility with emscripten :ghpull:`14316`, :ghpull:`14318`,
  - Test more downstream project to avoid breakage :ghpull:`14317`
  - Fix recently introduced bug with the ``store`` magic.
  - Fix issues with multiple call to ``matplotlib.pyplot.switch_backend``
  - Fix crashing IPython when some tracebacks encounter dynamically evaluated
    code.
 
 IPython 8.22.1 increase the minimal traitlets version, and 8.22.2 fix a critical
 bug on emscripten  preventing to use some magics like ``%matplotlib`` on
 jupyter-light.
 
 API changes
 -----------
 
 One of the largest change is the update the mimehooks and inspector API, see
 :ghpull:`14342`. It should be backward compatible, but many hooks now receive a
 single object with many fields allowing us flexibility to update the API later.
 
 
 Packaging changes
 -----------------
 
 Thanks to `@mkoppe <https://github.com/mkoeppe>`__, we are slowly getting rid of
 setup.py finally migrating to ``pyproject.toml``. There is still quite a bit of
 work, and please open an issue if you encounter any problem.
 
 
 Deprecation
 -----------
 
 A number of unused functions have been marked deprecated or pending deprecation.
 Please let us know if you encounter any of those deprecation messages for us to
 adjust the removal timeline.
 
 
 Thanks
 ------
 
 Many thanks to `@mkoppe <https://github.com/mkoeppe>`__ and `@krassowski
 <https://github.com/krassowski>`__ for their multiple contributions and codebase
 cleanup.

 .. _version 8.21:
 
 IPython 8.21
 ------------
 
 More substantial release of IPython slightly out of schedule as it was not
 possible for me to make a release last Friday.
 
 Few new features are present, but the codebase has been cleaned, and a couple
 of API are _considered_ for deprecation. They are not deprecated yet, but as
 they do not seem to be quite used, they may emit a warning, in which case please
 comment on the relevant issue to inform me of _which_ project use those feature
 and how you use them. Depending on the feedback I might change the timeline for
 deprecation.
 
 This release saw 14 PRs, with more outside contribution than usual,
 I'll note in particular PRs related to making IPython work on emscripten.
 
 I also want to point that we are _trying_ to keep compatibility with Python 3.13,
 but it's a cat and mouse game. Plus I am low on time, so I would appreciate any
 help with that.
 
 Deprecations
 ~~~~~~~~~~~~
 
  - :ghpull:`14307` Pending Deprecation of
    ``ColorSchemeTable.set_active_scheme(...)``'s ``case_sensitive`` Parameter.
  - :ghpull:`14305` Pending Deprecation of constructing ``ColorScheme`` via
    ``kwargs``, in favor passing a single dict.
 
 
 Fixes
 ~~~~~
 
  - :ghpull:`14284` TerminalIPythonApp's would warn that ``auto_create`` option is not
    recognized.
  - :ghpull:`14286` Fix a crash with ``NotOneValueFound`` when rendering complex
    tracebacks.
 
  - :ghpull:`14287` Partial Python 3.13 compatibility
  - :ghpull:`14290` Docs/Typos.
 
 Changes
 ~~~~~~~
 
  - :ghpull:`14289` ``ipdb.set_trace()`` now accepts ``header=`` for better
    compatibility with ``pdb.set_trace()``
 
  - :ghpull:`14300` and :ghpull:`14301` Add hooking ability to produce
    mimebundle.
 
 We'll outline :ghpull:`14300`, it is now possible to extend the ``?/??``
 operator to return more mimetypes to render richer help in frontends that
 support it. In particular you could send a json representation of the help that
 could be displayed in a customizable way.
 
 Miscellaneous
 ~~~~~~~~~~~~~
 
  - :ghpull:`14291` Misc Refactor of Color handling
  - :ghpull:`14295` Misc test skip on problematic Pypy versions.
 
 
 Thanks
 ~~~~~~
 
 Special thanks to all our contributors, and to the Pypy team that was extremely
 reactive in helping to investigate a fixing a rare unicode+windows bug.

 .. _version 8.20:
 
 IPython 8.20
 ------------
 
 Quick IPython release in this beginning of 2024, barely 2 weeks after the previous
 release.
 
 This is mostly to fix a backward compatibility issue, I would have done a  patch
 release earlier if I could. As a few other cleanup are also part of this
 release, this will get a minor version bump.
 
 
 The crux of this release is :ghpull:`14274` (Inspect continuation prompt
 signature and pass only viable arguments), the rest of the changes are mostly
 type annotation, and a few compatibility issues with Python 3.13 that are
 getting addressed.
 
 Python 3.13 compatibility is still not complete (help welcomed).

 .. _version 8.19:
 
 IPython 8.19
 ------------
 
 New release of IPython a bit before the end of the month, and end of the year.
 
 Mostly cleanup and deprecation, due to upstream deprecation and removal.
 
 Remove of Python 3.9 support
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 A bit later than originally plan, IPython 8.19 does not support Python 3.9
 anymore, as well as the few conditional code that were executing only on Python
 3.9. :ghpull:`14254`
 
 We used the opportunity to deprecate ``IPython.utils.tz`` :ghpull:`14256`, due
 to upstream deprecation of some timezone utilities. It will be removed at a later
 date.
 
 We now also run CI on Python 3.12 (what I likely should have done before), but
 running on too many Python version uses a lot of CI time.
 
 Absolute and relative Line Numbers in Prompts
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Thanks to the contribution of ``cohml``, IPython CLI now support absolute and
 relative line numbers in both vi and emacs prompt, use for example
 ``c.TerminalInteractiveShell.prompt_line_number_format='{line: 4d}/{rel_line:+03d} | '``
 configuration option to display both in a custom format.
 
 Miscellaneous
 ~~~~~~~~~~~~~
 
 In addition to various bugfixes, I unpinned pytest, let me know if there are any
 issues and we'll re-pin.
 
 See you in 2024

 .. _version 8.18:
 
 IPython 8.18 and 8.18.1
 -----------------------
 
 8.18.1 is identical to 8.18 but pin ``prompt_toolkit`` to greater than ``3.0.41``
 
 Small release of IPython that fixes a small number of inconveniences.
 
  - :ghpull:`14251` Fix a memory leak in qt event loop integration by setting
    the Loop parent to None.
  - :ghpull:`14252` Pickleshare was made an optional dependency in 8.17, this
    leads to warnings in some installations when using modules completions. The
    warning has been silenced.
  - :ghpull:`14241` Update event loop code for compatibility with more recent
    ``prompt_toolkit`` due to deprecations in Python 3.12.
  - :ghpull:`14245` Fix doc example on Pygments styles
  - :ghpull:`14238` Remove dependency on app_nope, this is actually only a
    dependency of IPykernel.

 .. _version 8.17.1:
 .. _version 8.17:
 
 IPython 8.17, 8.17.1
 --------------------
 
 Medium-sized release of IPython that includes some cleanup (backcall, python2 leftovers)
 and some refactoring improvements (typing, pathlib) and a fix on completion.
 
   - :ghpull:`14216` remove backcall dependency
   - :ghpull:`14217` make pickleshare dependency optional
   - :ghpull:`14185` support completion based on type annotations of calls
 
 Reverted in 8.17.1:
 
   - :ghpull:`14190` remove support for python 2 in lexers (reverted in 8.17.1 as it is imported by qtconsole/spyder)
 
-.. _ref: mamba-and-micromamba-magic
-.. _ref: mamba-and-micromamba-magic-commands
 
 Mamba and Micromamba magic commands
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 In addition to the ``%conda`` magic command for calling ``conda`` in IPython,
 the ``%mamba`` and ``%micromamba`` magic commands now
 call ``mamba`` and ``micromamba`` if they are on ``sys.path``.
 
 .. code:: python
 
    %mamba install pkgname
    %micromamba install pkgname
    %conda install pkgname
    %pip install pkgname
 
    %mamba --help

 .. _version 8.16:
 .. _version 8.16.1:
 
 IPython 8.16, 8.16.1
 --------------------
 
 Small double release of IPython (with the 8.12.3 release notes just below).
 Mostly bug fixes and cleanups, and type annotations. Of interest for users:
 
  - :ghpull:`14153` Fix a bug of the new iPdb chained traceback where some
    Exception would not have any traceback. (see upstream fix in CPython for more
    details).
  - :ghpull:`14168` Fix case with spurious message about event loops when using
    matplotlib.
 
 This PR is in 8.16.0 but reverted in 8.16.1, we'll  rework the fix for 8.17
 
  - :ghpull:`14163` Fix an error where semicolon would not suppress output.

 .. _version 8.12.3:
 
 IPython 8.12.3
 --------------
 
 Tiny release of 8.12.3 that backport a small number of fixes for users still
 using Python 3.8.
 
  - :ghpull:`14080` add passthrough filter shortcuts
  - :ghpull:`14169` Fix `InteractiveShellEmbed`
 
 .. _version 8.15:
 
 IPython 8.15
 ------------
 
 Medium release of IPython after a couple of month hiatus, and a bit
 off-schedule.
 
 Among other, IPython 8.15:
 
  - Improve compatibility with future version of Python 3.12/3.13
    :ghpull:`14107`, :ghpull:`14139`,
  - Improve support for ``ExceptionGroups``, :ghpull:`14108`
  - Fix hangs in ``%gui osx``, :ghpull:`14125`
  - Fix memory lead with ``%reset``, :ghpull:`14133`
  - Unstable config option to modify traceback highlighting that is sometime hard
    to read :ghpull:`14138`
  - Support ``.`` in ``ipdb`` as an argument to the ``list`` command
    :ghpull:`14121`
  - Workroud ``parso`` showing warning message when the default logger level is
    changed :ghpull:`14119`
  - Fix multiple issues with matplotlib interactive mode, qt5/qt6 :ghpull:`14128`
 
 Support for PEP-678 Exception Notes
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Ultratb now shows :pep:`678` notes, improving your debugging experience on
 Python 3.11+ or with libraries such as Pytest and Hypothesis.
 
 Native fallback for displaying ExceptionGroup
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 ExceptionGroups are now displayed with ``traceback.print_exc``, as a temporary fix until UltraTB properly supports displaying child exceptions.
 
 
 We have two larger features:
 
 AST-based macros
 ~~~~~~~~~~~~~~~~
 
 :ghpull:`14100` introduce a new and efficient way to modify each execution block
 (cell) using an template-ast-based transform. Unlike IPython pre and post code
 execution hooks, this actually transform the code that is execute with as
 minimal as possible overhead. While it was already technically possible to
 register ast transformers for IPython this was far from evident.
 
 This should make it trivial to hook into IPython to implement custom hooks, that
 for example time or profile your code, catch exceptions to provide error
 messages for students or do any other kind of transformations.
 
 In addition to programmatic API there is also a magic to quickly register
 hooks::
 
    In [1]: %%code_wrap before_after
       ...: print('before')
       ...: __code__
       ...: print('after')
       ...: __ret__
 
 This mean that  for any subsequent execution code will be executed.
 You can modify the above to print the date, compute the execution time,
 retry the code in a for loop....
 
 
 Allow IPdb/Pdb to move between chained exceptions
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 The main change is the addition of the ability to move between chained
 exceptions when using IPdb, this feature was also contributed to upstream Pdb
 and is thus native to CPython in Python 3.13+ Though ipdb should support this
 feature in older version of Python. I invite you to look at the `CPython changes
 and docs <https://github.com/python/cpython/pull/106676>`__ for more details.
 
 In short, once in post-mortem debugger (``%debug``), you can use the ipdb
 ``exceptions`` command to switch exceptions, for example:
 
 .. code-block:: ipython
 
     In [1]: def foo(x):
         ...:     try:
         ...:         bar(x)
         ...:     except Exception as e:
         ...:         raise ValueError("foo (): bar failed") from e
         ...:
         ...: def bar(x):
         ...:     1 / X
         ...:
 
     In [2]: foo(0)
     ---------------------------------------------------------------------------
     NameError                                 Traceback (most recent call last)
     Cell In[1], line 3, in foo(x)
           2 try:
     ----> 3     bar(x)
           4 except Exception as e:
 
     Cell In[1], line 9, in bar(x)
           8 def bar(x):
     ----> 9     1 / X
 
     NameError: name 'X' is not defined
 
     The above exception was the direct cause of the following exception:
 
     ValueError                                Traceback (most recent call last)
     Cell In[2], line 1
     ----> 1 foo(0)
 
     Cell In[1], line 5, in foo(x)
           3     bar(x)
           4 except Exception as e:
     ----> 5     raise ValueError("foo (): bar failed") from e
 
     ValueError: foo (): bar failed
 
     In [3]: %debug
     > <ipython-input-1-b0bbdc271ffb>(5)foo()
           3         bar(x)
           4     except Exception as e:
     ----> 5         raise ValueError("foo (): bar failed") from e
 
 In previous ipdb you could not go into the bar error, now from within pdb you
 can use ``exceptions``:
 
 .. code-block:: ipython
 
     ipdb> exceptions
         0 NameError("name 'X' is not defined")
     >   1 ValueError('foo (): bar failed')
 
     ipdb> exceptions 0
     > <ipython-input-1-b0bbdc271ffb>(9)bar()
           6
           7
           8 def bar(x):
     ----> 9     1 / X
          10
 
     ipdb>
 
 In particular I want to thank the `D.E. Shaw group <https://www.deshaw.com/>`__
 for suggesting and funding the two largest feature as well as many bug fixes of
 this release.

 .. _version 8.14:
 
 IPython 8.14
 ------------
 
 Small release of IPython.
 
  - :ghpull:`14080` fixes some shortcuts issues.
  - :ghpull:`14056` Add option to ``%autoreload`` to hide errors when reloading code. This will be the default for spyder
    user is my understanding.
  - :ghpull:`14039` (and :ghpull:`14040`) to show exception notes in tracebacks.
 
  - :ghpull:`14076` Add option to EventManager to prevent printing
 
 
 SPEC 0 and SPEC 4
 ~~~~~~~~~~~~~~~~~
 
 You've heard about the NEPs, (NumPy enhancement Proposal), having a NEP for something non-numpy specific was sometime confusing.
 Long live the `SPECs <https://scientific-python.org/specs/>`_.
 
 We are now trying to follow SPEC 0 (aka old NEP 29) for support of upstream libraries.
 
 We also now try to follow SPEC 4 (test and publish nightly on a centralized nightly repository).
 We encourage you to do so as well in order to report breakage, and contribute to the SPEC process !
 
 
 Python 3.12 compatibility ?
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Python 3.12 changed its tokenizer to have better support for f-strings and allow arbitrary expression.
 This is a great new feature and performance improvement in Python 3.12.
 
 Unfortunately this means the new tokenizer does not support incomplete or invalid Python which will
 break many features of IPython. Thus compatibility of IPython with Python 3.12 is not guarantied.
 It is unclear to which extent IPython is affected, and whether we can/should try to still support magics, shell
 escape (``! ....``), ...,  as well as how to do it if we can.
 
 In addition even if we there is technical feasibility to do so, it is no clear we have the resources to do it.
 We are thus looking for your help if you can _test_ on Python 3.12 to see to which extent this affects users and which
 features are critical.
 
 We are not going to pin IPython to Python ``<3.12`` as otherwise on install pip would downgrade/resolve to IPython 8.13,
 so if you plan to update to Python 3.12 after its release, we encourage for extra care.
 
 
 .. _version 8.13.1:
 .. _version 8.13.2:
 .. _version 8.12.2:
 
 IPython 8.13.1, 8.13.2 and 8.12.2
 ---------------------------------
 
 3 quick in succession patch release of IPython in addition to IPython 8.13.0
 having been yanked.
 
 IPython 8.13.0 was improperly tagged as still compatible with Python 3.8, and
 still had some mention of compatibility with 3.8. IPython 8.13.1 is identical to
 8.13 but with the exception of being correctly tagged. This release and yank was
 mostly done to fix CI.
 
 IPython 8.12.2 and 8.13.2 contain UI fixes, with respect to right arrow not
 working in some case in the terminal, and 8.12.2 contain also a requested
 backport of :ghpull:`14029` (Allow safe access to the ``__getattribute__``
 method of modules) for tab completion.
 
 .. _version 8.13:
 
 IPython 8.13
 ------------
 
 As usual for the end of the month, minor release of IPython. This release is
 significant in that it not only has a number of bugfixes, but also drop support
 for Python 3.8 as per NEP 29 (:ghpull:`14023`).
 
 All the critical bugfixes have been backported onto the 8.12.1 release (see
 below). In addition to that went into 8.12.1 you'll find:
 
  - Pretty representation for ``Counter`` has been fixed to match the Python one
    and be in decreasing order. :ghpull:`14032`
  - Module completion is better when jedi is disabled :ghpull:`14029`.
  - Improvement of ``%%bash`` magic that would get stuck :ghpull:`14019`
 
 
 We hope you enjoy this release an will maybe see you at JupyterCon in less than
 two weeks.
 
 As usual you can find the full list of PRs on GitHub under `the 8.13 milestone
 <https://github.com/ipython/ipython/milestone/115?closed=1>`__.

 .. _version 8.12.1:
 
 IPython 8.12.1
 --------------
 
 This is the twin release of IPython 8.13 that contain only critical UI and bug
 fixes. The next minor version of IPython has dropped support for Python 3.8 – as
 per Nep 29 and this IPython 8.12.x will now only receive bugfixes.
 
 
  - :ghpull:`14004` Fix a bug introduced in IPython 8.12 that crash when
    inspecting some docstrings.
  - :ghpull:`14010` Fix fast traceback code that was not working in some case.
  - :ghpull:`14014` Fix ``%page`` magic broken in some case.
  - :ghpull:`14026`, :ghpull:`14027` Tweak default shortcut with respect to
    autosuggestions.
  - :ghpull:`14033` add back the ability to use ``.get()`` on OInfo object for
    backward compatibility with h5py (this will be re-deprecated later, and h5py
    will also get a fix).

 .. _version 8.12.0:
 
 IPython 8.12
 ------------
 
 Hopefully slightly early release for IPython 8.12. Last Thursday of the month,
 even if I guess it's likely already Friday somewhere in the pacific ocean.
 
 A number of PRs and bug fixes this month with close to 20 PRs merged !
 
 
 The IPython repo reached :ghpull:`14000` !! Actually the PR that create those exact release
 note is :ghpull:`14000`. Ok, more issues and PR is not always better, and I'd
 love to have more time to close issues and Pull Requests.
 
 Let's note that in less than 2 month JupyterCon is back, in Paris please visit
 `jupytercon.com <https://jupytercon.com>`__, and looking forward to see you
 there.
 
 Packagers should take note that ``typing_extension`` is now a mandatory dependency
 for Python versions ``<3.10``.
 
 
 
 Let's note also that according to `NEP29
 <https://numpy.org/neps/nep-0029-deprecation_policy.html>`__, It is soon time to
 stop support for Python 3.8 that will be release more than 3 and 1/2 years ago::
 
     On Apr 14, 2023 drop support for Python 3.8 (initially released on Oct 14, 2019)
 
 Thus I am likely to stop advertising support for Python 3.8 in the next
 release at the end of April.
 
 
 Here are some miscellaneous updates of interest:
 
  - :ghpull:`13957` brings updates to the Qt integration, particularly for Qt6.
  - :ghpull:`13960` fixes the %debug magic command to give access to the local
    scope.
  - :ghpull:`13964` fixes some crashes with the new fast traceback code. Note that
    there are still some issues with the fast traceback code, and I a, likely
    to fix and tweak behavior.
  - :ghpull:`13973` We are slowly migrating IPython internals to use proper type
    objects/dataclasses instead of dictionaries to allow static typing checks.
    These are technically public API and could lead to breakage, so please let us
    know if that's the case and I'll mitigate.
  - :ghpull:`13990`, :ghpull:`13991`, :ghpull:`13994` all improve keybinding and
    shortcut configurability.

 We want to thank the D.E. Shaw group for requesting and sponsoring the work on
 the following big feature. We had productive discussions on how to best expose
 this feature
 
 Dynamic documentation dispatch
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 We are experimenting with dynamic documentation dispatch for object attribute.
 See :ghissue:`13860`. The goal is to allow object to define documentation for
 their attributes, properties, even when those are dynamically defined with
 `__getattr__`.
 
 In particular when those objects are base types it can be useful to show the
 documentation
 
 
 .. code-block:: ipython
 
 
     In [1]: class User:
        ...:
        ...:     __custom_documentations__ = {
        ...:         "first": "The first name of the user.",
        ...:         "last": "The last name of the user.",
        ...:     }
        ...:
        ...:     first:str
        ...:     last:str
        ...:
        ...:     def __init__(self, first, last):
        ...:         self.first = first
        ...:         self.last = last
        ...:
        ...:     @property
        ...:     def full(self):
        ...:         """`self.first` and `self.last` joined by a space."""
        ...:         return self.first + " " + self.last
        ...:
        ...:
        ...: user = Person('Jane', 'Doe')
 
     In [2]: user.first?
     Type:            str
     String form:     Jane
     Length:          4
     Docstring:       the first name of a the person object, a str
     Class docstring:
     ....
 
     In [3]: user.last?
     Type:            str
     String form:     Doe
     Length:          3
     Docstring:       the last name, also a str
     ...
 
 
 We can see here the symmetry with IPython looking for the docstring on the
 properties:
 
 .. code-block:: ipython
 
 
     In [4]: user.full?
     HERE
     Type:        property
     String form: <property object at 0x102bb15d0>
     Docstring:   first and last join by a space
 
 
 Note that while in the above example we use a static dictionary, libraries may
 decide to use a custom object that define ``__getitem__``, we caution against
 using objects that would trigger computation to show documentation, but it is
 sometime preferable for highly dynamic code that for example export ans API as
 object.
 
 
 
 .. _version 8.11.0:
 
 IPython 8.11
 ------------
 
 Back on almost regular monthly schedule for IPython with end-of-month
 really-late-Friday release to make sure some bugs are properly fixed.
 Small addition of with a few new features, bugfix and UX improvements.
 
 This is a non-exhaustive list, but among other you will find:
 
 Faster Traceback Highlighting
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Resurrection of pre-IPython-8 traceback highlighting code.
 
 Really long and complicated files were slow to highlight in traceback with
 IPython 8 despite upstream improvement that make many case better. Therefore
 starting with IPython 8.11 when one of the highlighted file is more than 10 000
 line long by default, we'll fallback to a faster path that does not have all the
 features of highlighting failing AST nodes.
 
 This can be configures by setting the value of
 ``IPython.code.ultratb.FAST_THRESHOLD`` to an arbitrary low or large value.
 
 
 Autoreload verbosity
 ~~~~~~~~~~~~~~~~~~~~
 
 We introduce more descriptive names for the ``%autoreload`` parameter:
 
 - ``%autoreload now`` (also ``%autoreload``) - perform autoreload immediately.
 - ``%autoreload off`` (also ``%autoreload 0``) - turn off autoreload.
 - ``%autoreload explicit`` (also ``%autoreload 1``) - turn on autoreload only for modules
   whitelisted by ``%aimport`` statements.
 - ``%autoreload all`` (also ``%autoreload 2``) - turn on autoreload for all modules except those
   blacklisted by ``%aimport`` statements.
 - ``%autoreload complete`` (also ``%autoreload 3``) - all the fatures of ``all`` but also adding new
   objects from the imported modules (see
   IPython/extensions/tests/test_autoreload.py::test_autoload_newly_added_objects).
 
 The original designations (e.g. "2") still work, and these new ones are case-insensitive.
 
 Additionally, the option ``--print`` or ``-p`` can be added to the line to print the names of
 modules being reloaded. Similarly, ``--log`` or ``-l`` will output the names to the logger at INFO
 level. Both can be used simultaneously.
 
 The parsing logic for ``%aimport`` is now improved such that modules can be whitelisted and
 blacklisted in the same line, e.g. it's now possible to call ``%aimport os, -math`` to include
 ``os`` for ``%autoreload explicit`` and exclude ``math`` for modes ``all`` and ``complete``.
 
 Terminal shortcuts customization
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Previously modifying shortcuts was only possible by hooking into startup files
 and practically limited to adding new shortcuts or removing all shortcuts bound
 to a specific key. This release enables users to override existing terminal
 shortcuts, disable them or add new keybindings.
 
 For example, to set the :kbd:`right` to accept a single character of auto-suggestion
 you could use::
 
     my_shortcuts = [
         {
             "command": "IPython:auto_suggest.accept_character",
             "new_keys": ["right"]
         }
     ]
     %config TerminalInteractiveShell.shortcuts = my_shortcuts
 
 You can learn more in :std:configtrait:`TerminalInteractiveShell.shortcuts`
 configuration reference.
 
 Miscellaneous
 ~~~~~~~~~~~~~
 
  - ``%gui`` should now support PySide6. :ghpull:`13864`
  - Cli shortcuts can now be configured :ghpull:`13928`, see above.
    (note that there might be an issue with prompt_toolkit 3.0.37 and shortcut configuration).
 
  - Capture output should now respect ``;`` semicolon to suppress output.
    :ghpull:`13940`
  - Base64 encoded images (in jupyter frontend), will not have trailing newlines.
    :ghpull:`13941`

 .. _version 8.10.0:
 
 IPython 8.10
 ------------
 
 Out of schedule release of IPython with minor fixes to patch a potential CVE-2023-24816.
 This is a really low severity CVE that you most likely are not affected by unless:
 
  - You are on windows.
  - You have a custom build of Python without ``_ctypes``
  - You cd or start IPython or Jupyter in untrusted directory which names may be
    valid shell commands.
 
 You can read more on `the advisory
 <https://github.com/ipython/ipython/security/advisories/GHSA-29gw-9793-fvw7>`__.
 
 In addition to fixing this CVE we also fix a couple of outstanding bugs and issues.
 
 As usual you can find the full list of PRs on GitHub under `the 8.10 milestone
 <https://github.com/ipython/ipython/milestone/112?closed=1>`__.
 
 In Particular:
 
  - bump minimum numpy to `>=1.21` version following NEP29. :ghpull:`13930`
  - fix for compatibility with MyPy 1.0. :ghpull:`13933`
  - fix nbgrader stalling when IPython's ``showtraceback`` function is
    monkeypatched. :ghpull:`13934`
 
 
 
 As this release also contains those minimal changes in addition to fixing the
 CVE I decided to bump the minor version anyway.
 
 This will not affect the normal release schedule, so IPython 8.11 is due in
 about 2 weeks.
 
 .. _version 8.9.0:
 
 IPython 8.9.0
 -------------
 
 Second release of IPython in 2023, last Friday of the month, we are back on
 track. This is a small release with a few bug-fixes, and improvements, mostly
 with respect to terminal shortcuts.
 
 
 The biggest improvement for 8.9 is a drastic amelioration of the
 auto-suggestions sponsored by D.E. Shaw and implemented by the more and more
 active contributor `@krassowski <https://github.com/krassowski>`.
 
 - ``right`` accepts a single character from suggestion
 - ``ctrl+right`` accepts a semantic token (macos default shortcuts take
   precedence and need to be disabled to make this work)
 - ``backspace`` deletes a character and resumes hinting autosuggestions
 - ``ctrl-left`` accepts suggestion and moves cursor left one character.
 - ``backspace`` deletes a character and resumes hinting autosuggestions
 - ``down`` moves to suggestion to later in history when no lines are present below the cursors.
 - ``up`` moves to suggestion from earlier in history when no lines are present above the cursor.
 
 This is best described by the Gif posted by `@krassowski
 <https://github.com/krassowski>`, and in the PR itself :ghpull:`13888`.
 
 .. image:: ../_images/autosuggest.gif
 
 Please report any feedback in order for us to improve the user experience.
 In particular we are also working on making the shortcuts configurable.
 
 If you are interested in better terminal shortcuts, I also invite you to
 participate in issue `13879
 <https://github.com/ipython/ipython/issues/13879>`__.
 
 
 As we follow `NEP29
 <https://numpy.org/neps/nep-0029-deprecation_policy.html>`__, next version of
 IPython will officially stop supporting numpy 1.20, and will stop supporting
 Python 3.8 after April release.

 .. _version 8.8.0:
 
 IPython 8.8.0
 -------------
 
 First release of IPython in 2023 as there was no release at the end of
 December.
 
 This is an unusually big release (relatively speaking) with more than 15 Pull
 Requests merged.
 
 Of particular interest are:
 
  - :ghpull:`13852` that replaces the greedy completer and improves
    completion, in particular for dictionary keys.
  - :ghpull:`13858` that adds ``py.typed`` to ``setup.cfg`` to make sure it is
    bundled in wheels.
  - :ghpull:`13869` that implements tab completions for IPython options in the
    shell when using `argcomplete <https://github.com/kislyuk/argcomplete>`. I
    believe this also needs a recent version of Traitlets.
  - :ghpull:`13865` makes the ``inspector`` class of `InteractiveShell`
    configurable.
  - :ghpull:`13880` that removes minor-version entrypoints as the minor version
    entry points that would be included in the wheel would be the one of the
    Python version that was used to build the ``whl`` file.
 
 In no particular order, the rest of the changes update the test suite to be
 compatible with Pygments 2.14, various docfixes, testing on more recent python
 versions and various updates.
 
 As usual you can find the full list of PRs on GitHub under `the 8.8 milestone
 <https://github.com/ipython/ipython/milestone/110>`__.
 
 Many thanks to @krassowski for the many PRs and @jasongrout for reviewing and
 merging contributions.

 .. _version 8.7.0:
 
 IPython 8.7.0
 -------------
 
 
 Small release of IPython with a couple of bug fixes and new features for this
 month. Next month is the end of year, it is unclear if there will be a release
 close to the new year's eve, or if the next release will be at the end of January.
 
 Here are a few of the relevant fixes,
 as usual you can find the full list of PRs on GitHub under `the 8.7 milestone
 <https://github.com/ipython/ipython/pulls?q=milestone%3A8.7>`__.
 
 
    - :ghpull:`13834` bump the minimum prompt toolkit to 3.0.11.
    - IPython shipped with the ``py.typed`` marker now, and we are progressively
      adding more types. :ghpull:`13831`
    - :ghpull:`13817` add configuration of code blacks formatting.
 
 
 Thanks to the `D. E. Shaw group <https://deshaw.com/>`__ for sponsoring
 work on IPython and related libraries.
 
 
 .. _version 8.6.0:
 
 IPython 8.6.0
 -------------
 
 Back to a more regular release schedule (at least I try), as Friday is
 already over by more than 24h hours. This is a slightly bigger release with a
 few new features that contain no less than 25 PRs.
 
 We'll notably found a couple of non negligible changes:
 
 The ``install_ext`` and related functions have been removed after being
 deprecated for years. You can use pip to install extensions. ``pip`` did not
 exist when ``install_ext`` was introduced. You can still load local extensions
 without installing them. Just set your ``sys.path`` for example. :ghpull:`13744`
 
 IPython now has extra entry points that use the major *and minor* version of
 python. For some of you this means that you can do a quick ``ipython3.10`` to
 launch IPython from the Python 3.10 interpreter, while still using Python 3.11
 as your main Python. :ghpull:`13743`
 
 The completer matcher API has been improved. See :ghpull:`13745`. This should
 improve the type inference and improve dict keys completions in many use case.
 Thanks ``@krassowski`` for all the work, and the D.E. Shaw group for sponsoring
 it.
 
 The color of error nodes in tracebacks can now be customized. See
 :ghpull:`13756`. This is a private attribute until someone finds the time to
 properly add a configuration option. Note that with Python 3.11 that also shows
 the relevant nodes in traceback, it would be good to leverage this information
 (plus the "did you mean" info added on attribute errors). But that's likely work
 I won't have time to do before long, so contributions welcome.
 
 As we follow NEP 29, we removed support for numpy 1.19 :ghpull:`13760`.
 
 
 The ``open()`` function present in the user namespace by default will now refuse
 to open the file descriptors 0,1,2 (stdin, out, err), to avoid crashing IPython.
 This mostly occurs in teaching context when incorrect values get passed around.
 
 
 The ``?``, ``??``, and corresponding ``pinfo``, ``pinfo2`` magics can now find
 objects inside arrays. That is to say, the following now works::
 
 
    >>> def my_func(*arg, **kwargs):pass
    >>> container = [my_func]
    >>> container[0]?
 
 
 If ``container`` define a custom ``getitem``, this __will__ trigger the custom
 method. So don't put side effects in your ``getitems``. Thanks to the D.E. Shaw
 group for the request and sponsoring the work.

 .. _version 8.5.0:
 
 IPython 8.5.0
 -------------
 
 First release since a couple of month due to various reasons and timing preventing
 me for sticking to the usual monthly release the last Friday of each month. This
 is of non negligible size as it has more than two dozen PRs with various fixes
 an bug fixes.
 
 Many thanks to everybody who contributed PRs for your patience in review and
 merges.
 
 Here is a non-exhaustive list of changes that have been implemented for IPython
 8.5.0. As usual you can find the full list of issues and PRs tagged with `the
 8.5 milestone
 <https://github.com/ipython/ipython/pulls?q=is%3Aclosed+milestone%3A8.5+>`__.
 
  - Added a shortcut for accepting auto suggestion. The End key shortcut for
    accepting auto-suggestion This binding works in Vi mode too, provided
    ``TerminalInteractiveShell.emacs_bindings_in_vi_insert_mode`` is set to be
    ``True`` :ghpull:`13566`.
 
  - No popup in window for latex generation when generating latex (e.g. via
    `_latex_repr_`) no popup window is shows under Windows. :ghpull:`13679`
 
  - Fixed error raised when attempting to tab-complete an input string with
    consecutive periods or forward slashes (such as "file:///var/log/...").
    :ghpull:`13675`
 
  - Relative filenames in Latex rendering :
    The `latex_to_png_dvipng` command internally generates input and output file
    arguments to `latex` and `dvipis`. These arguments are now generated as
    relative files to the current working directory instead of absolute file
    paths. This solves a problem where the current working directory contains
    characters that are not handled properly by `latex` and `dvips`. There are
    no changes to the user API. :ghpull:`13680`
 
  - Stripping decorators bug: Fixed bug which meant that ipython code blocks in
    restructured text documents executed with the ipython-sphinx extension
    skipped any lines of code containing python decorators. :ghpull:`13612`
 
  - Allow some modules with frozen dataclasses to be reloaded. :ghpull:`13732`
  - Fix paste magic on wayland. :ghpull:`13671`
  - show maxlen in deque's repr. :ghpull:`13648`
 
 Restore line numbers for Input
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Line number information in tracebacks from input are restored.
 Line numbers from input were removed during the transition to v8 enhanced traceback reporting.
 
 So, instead of::
 
     ---------------------------------------------------------------------------
     ZeroDivisionError                         Traceback (most recent call last)
     Input In [3], in <cell line: 1>()
     ----> 1 myfunc(2)
 
     Input In [2], in myfunc(z)
           1 def myfunc(z):
     ----> 2     foo.boo(z-1)
 
     File ~/code/python/ipython/foo.py:3, in boo(x)
           2 def boo(x):
     ----> 3     return 1/(1-x)
 
     ZeroDivisionError: division by zero
 
 The error traceback now looks like::
 
       ---------------------------------------------------------------------------
       ZeroDivisionError                         Traceback (most recent call last)
       Cell In [3], line 1
       ----> 1 myfunc(2)
 
       Cell In [2], line 2, in myfunc(z)
             1 def myfunc(z):
       ----> 2     foo.boo(z-1)
 
       File ~/code/python/ipython/foo.py:3, in boo(x)
             2 def boo(x):
       ----> 3     return 1/(1-x)
 
       ZeroDivisionError: division by zero
 
 or, with xmode=Plain::
 
     Traceback (most recent call last):
       Cell In [12], line 1
         myfunc(2)
       Cell In [6], line 2 in myfunc
         foo.boo(z-1)
       File ~/code/python/ipython/foo.py:3 in boo
         return 1/(1-x)
     ZeroDivisionError: division by zero
 
 :ghpull:`13560`
 
 New setting to silence warning if working inside a virtual environment
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Previously, when starting IPython in a virtual environment without IPython installed (so IPython from the global environment is used), the following warning was printed:
 
     Attempting to work in a virtualenv. If you encounter problems, please install IPython inside the virtualenv.
 
 This warning can be permanently silenced by setting ``c.InteractiveShell.warn_venv`` to ``False`` (the default is ``True``).

 .. _version 8.3.0:
 
 IPython 8.3.0
 -------------
 
  - :ghpull:`13625`, using ``?``, ``??``, ``*?`` will not call
    ``set_next_input`` as most frontend allow proper multiline editing and it was
    causing issues for many users of multi-cell frontends. This has been backported to 7.33
 
 
  - :ghpull:`13600`, ``pre_run_*``-hooks will now have a ``cell_id`` attribute on
    the info object when frontend provides it. This has been backported to 7.33
 
  - :ghpull:`13624`, fixed :kbd:`End` key being broken after accepting an
    auto-suggestion.
 
  - :ghpull:`13657` fixed an issue where history from different sessions would be mixed.
 
 .. _version 8.2.0:
 
 IPython 8.2.0
 -------------
 
 IPython 8.2 mostly bring bugfixes to IPython.
 
  - Auto-suggestion can now be elected with the ``end`` key. :ghpull:`13566`
  - Some traceback issues with ``assert etb is not None`` have been fixed. :ghpull:`13588`
  - History is now pulled from the sqitel database and not from in-memory.
    In particular when using the ``%paste`` magic, the content of the pasted text will
    be part of the history and not the verbatim text ``%paste`` anymore. :ghpull:`13592`
  - Fix ``Ctrl-\\`` exit cleanup :ghpull:`13603`
  - Fixes to ``ultratb`` ipdb support when used outside of IPython. :ghpull:`13498`
 
 
 I am still trying to fix and investigate :ghissue:`13598`, which seems to be
 random, and would appreciate help if you find a reproducible minimal case. I've
 tried to make various changes to the codebase to mitigate it, but a proper fix
 will be difficult without understanding the cause.

 .. _version 8.1.1:
 
 IPython 8.1.1
 -------------
 
 Fix an issue with virtualenv and Python 3.8 introduced in 8.1
 
 Revert :ghpull:`13537` (fix an issue with symlinks in virtualenv) that raises an
 error in Python 3.8, and fixed in a different way in :ghpull:`13559`.
 
 .. _version 8.1:
 
 IPython 8.1.0
 -------------
 
 IPython 8.1 is the first minor release after 8.0 and fixes a number of bugs and
 updates a few behaviors that were problematic with the 8.0 as with many new major
 release.
 
 Note that beyond the changes listed here, IPython 8.1.0 also contains all the
 features listed in :ref:`version 7.32`.
 
  - Misc and multiple fixes around quotation auto-closing. It is now disabled by
    default. Run with ``TerminalInteractiveShell.auto_match=True`` to re-enabled
  - Require pygments>=2.4.0 :ghpull:`13459`, this was implicit in the code, but
    is now explicit in ``setup.cfg``/``setup.py``
  - Docs improvement of ``core.magic_arguments`` examples. :ghpull:`13433`
  - Multi-line edit executes too early with await. :ghpull:`13424`
 
  - ``black``  is back as an optional dependency, and autoformatting disabled by
    default until some fixes are implemented (black improperly reformat magics).
    :ghpull:`13471` Additionally the ability to use ``yapf`` as a code
    reformatter has been added :ghpull:`13528` . You can use
    ``TerminalInteractiveShell.autoformatter="black"``,
    ``TerminalInteractiveShell.autoformatter="yapf"`` to re-enable auto formatting
    with black, or switch to yapf.
 
  - Fix and issue where ``display`` was not defined.
 
  - Auto suggestions are now configurable. Currently only
    ``AutoSuggestFromHistory`` (default) and ``None``. new provider contribution
    welcomed. :ghpull:`13475`
 
  - multiple packaging/testing improvement to simplify downstream packaging
    (xfail with reasons, try to not access network...).
 
  - Update deprecation. ``InteractiveShell.magic`` internal method has been
    deprecated for many years but did not emit a warning until now.
 
  - internal ``appended_to_syspath`` context manager has been deprecated.
 
  - fix an issue with symlinks in virtualenv :ghpull:`13537` (Reverted in 8.1.1)
 
  - Fix an issue with vim mode, where cursor would not be reset on exit :ghpull:`13472`
 
  - ipython directive now remove only known pseudo-decorators :ghpull:`13532`
 
  - ``IPython/lib/security`` which used to be used for jupyter notebook has been
    removed.
 
  - Fix an issue where ``async with`` would execute on new lines. :ghpull:`13436`
 
 
 We want to remind users that IPython is part of the Jupyter organisations, and
 thus governed by a Code of Conduct. Some of the behavior we have seen on GitHub is not acceptable.
 Abuse and non-respectful comments on discussion will not be tolerated.
 
 Many thanks to all the contributors to this release, many of the above fixed issues and
 new features were done by first time contributors, showing there is still
 plenty of easy contribution possible in IPython
 . You can find all individual contributions
 to this milestone `on github <https://github.com/ipython/ipython/milestone/91>`__.
 
 Thanks as well to the `D. E. Shaw group <https://deshaw.com/>`__ for sponsoring
 work on IPython and related libraries. In particular the Lazy autoloading of
 magics that you will find described in the 7.32 release notes.
 
 
 .. _version 8.0.1:
 
 IPython 8.0.1 (CVE-2022-21699)
 ------------------------------
 
 IPython 8.0.1, 7.31.1 and 5.11 are security releases that change some default
 values in order to prevent potential Execution with Unnecessary Privileges.
 
 Almost all version of IPython looks for configuration and profiles in current
 working directory. Since IPython was developed before pip and environments
 existed it was used a convenient way to load code/packages in a project
 dependant way.
 
 In 2022, it is not necessary anymore, and can lead to confusing behavior where
 for example cloning a repository and starting IPython or loading a notebook from
 any Jupyter-Compatible interface that has ipython set as a kernel can lead to
 code execution.
 
 
 I did not find any standard way for packaged to advertise CVEs they fix, I'm
 thus trying to add a ``__patched_cves__`` attribute to the IPython module that
 list the CVEs that should have been fixed. This attribute is informational only
 as if a executable has a flaw, this value can always be changed by an attacker.
 
 .. code::
 
     In [1]: import IPython
 
     In [2]: IPython.__patched_cves__
     Out[2]: {'CVE-2022-21699'}
 
     In [3]: 'CVE-2022-21699' in IPython.__patched_cves__
     Out[3]: True
 
 Thus starting with this version:
 
  - The current working directory is not searched anymore for profiles or
    configurations files.
  - Added a ``__patched_cves__`` attribute (set of strings) to IPython module that contain
    the list of fixed CVE. This is informational only.
 
 Further details can be read on the `GitHub Advisory <https://github.com/ipython/ipython/security/advisories/GHSA-pq7m-3gw7-gq5x>`__
 
 
 .. _version 8.0:
 
 IPython 8.0
 -----------
 
 IPython 8.0 is bringing a large number of new features and improvements to both the
 user of the terminal and of the kernel via Jupyter. The removal of compatibility
 with an older version of Python is also the opportunity to do a couple of
 performance improvements in particular with respect to startup time.
 The 8.x branch started diverging from its predecessor around IPython 7.12
 (January 2020).
 
 This release contains 250+ pull requests, in addition to many of the features
 and backports that have made it to the 7.x branch. Please see the
 `8.0 milestone <https://github.com/ipython/ipython/milestone/73?closed=1>`__ for the full list of pull requests.
 
 Please feel free to send pull requests to update those notes after release,
 I have likely forgotten a few things reviewing 250+ PRs.
 
 Dependencies changes/downstream packaging
 -----------------------------------------
 
 Most of our building steps have been changed to be (mostly) declarative
 and follow PEP 517. We are trying to completely remove ``setup.py`` (:ghpull:`13238`) and are
 looking for help to do so.
 
  - minimum supported ``traitlets`` version is now 5+
  - we now require ``stack_data``
  - minimal Python is now 3.8
  - ``nose`` is not a testing requirement anymore
  - ``pytest`` replaces nose.
  - ``iptest``/``iptest3`` cli entrypoints do not exist anymore.
  - the minimum officially ​supported ``numpy`` version has been bumped, but this should
    not have much effect on packaging.
 
 
 Deprecation and removal
 -----------------------
 
 We removed almost all features, arguments, functions, and modules that were
 marked as deprecated between IPython 1.0 and 5.0. As a reminder, 5.0 was released
 in 2016, and 1.0 in 2013. Last release of the 5 branch was 5.10.0, in May 2020.
 The few remaining deprecated features we left have better deprecation warnings
 or have been turned into explicit errors for better error messages.
 
 I will use this occasion to add the following requests to anyone emitting a
 deprecation warning:
 
  - Please add at least ``stacklevel=2`` so that the warning is emitted into the
    caller context, and not the callee one.
  - Please add **since which version** something is deprecated.
 
 As a side note, it is much easier to conditionally compare version
 numbers rather than using ``try/except`` when functionality changes with a version.
 
 I won't list all the removed features here, but modules like ``IPython.kernel``,
 which was just a shim module around ``ipykernel`` for the past 8 years, have been
 removed, and so many other similar things that pre-date the name **Jupyter**
 itself.
 
 We no longer need to add ``IPython.extensions`` to the PYTHONPATH because that is being
 handled by ``load_extension``.
 
 We are also removing ``Cythonmagic``, ``sympyprinting`` and ``rmagic`` as they are now in
 other packages and no longer need to be inside IPython.
 
 
 Documentation
 -------------
 
 The majority of our docstrings have now been reformatted and automatically fixed by
 the experimental `Vélin <https://pypi.org/project/velin/>`_ project to conform
 to numpydoc.
 
 Type annotations
 ----------------
 
 While IPython itself is highly dynamic and can't be completely typed, many of
 the functions now have type annotations, and part of the codebase is now checked
 by mypy.
 
 
 Featured changes
 ----------------
 
 Here is a features list of changes in IPython 8.0. This is of course non-exhaustive.
 Please note as well that many features have been added in the 7.x branch as well
 (and hence why you want to read the 7.x what's new notes), in particular
 features contributed by QuantStack (with respect to debugger protocol and Xeus
 Python), as well as many debugger features that I was pleased to implement as
 part of my work at QuanSight and sponsored by DE Shaw.
 
 Traceback improvements
 ~~~~~~~~~~~~~~~~~~~~~~
 
 Previously, error tracebacks for errors happening in code cells were showing a
 hash, the one used for compiling the Python AST::
 
     In [1]: def foo():
     ...:     return 3 / 0
     ...:
 
     In [2]: foo()
     ---------------------------------------------------------------------------
     ZeroDivisionError                         Traceback (most recent call last)
     <ipython-input-2-c19b6d9633cf> in <module>
     ----> 1 foo()
 
     <ipython-input-1-1595a74c32d5> in foo()
         1 def foo():
     ----> 2     return 3 / 0
         3
 
     ZeroDivisionError: division by zero
 
 The error traceback is now correctly formatted, showing the cell number in which the error happened::
 
     In [1]: def foo():
     ...:     return 3 / 0
     ...:
 
     Input In [2]: foo()
     ---------------------------------------------------------------------------
     ZeroDivisionError                         Traceback (most recent call last)
     input In [2], in <module>
     ----> 1 foo()
 
     Input In [1], in foo()
         1 def foo():
     ----> 2     return 3 / 0
 
     ZeroDivisionError: division by zero
 
 The ``stack_data`` package has been integrated, which provides smarter information in the traceback;
 in particular it will highlight the AST node where an error occurs which can help to quickly narrow down errors.
 
 For example in the following snippet::
 
     def foo(i):
         x = [[[0]]]
         return x[0][i][0]
 
 
     def bar():
         return foo(0) + foo(
             1
         ) + foo(2)
 
 
 calling ``bar()`` would raise an ``IndexError`` on the return line of ``foo``,
 and IPython 8.0 is capable of telling you where the index error occurs::
 
 
     IndexError
     Input In [2], in <module>
     ----> 1 bar()
             ^^^^^
 
     Input In [1], in bar()
           6 def bar():
     ----> 7     return foo(0) + foo(
                                 ^^^^
           8         1
              ^^^^^^^^
           9     ) + foo(2)
              ^^^^
 
     Input In [1], in foo(i)
           1 def foo(i):
           2     x = [[[0]]]
     ----> 3     return x[0][i][0]
                        ^^^^^^^
 
 The corresponding locations marked here with ``^`` will show up highlighted in
 the terminal and notebooks.
 
 Finally, a colon ``::`` and line number is appended after a filename in
 traceback::
 
 
     ZeroDivisionError               Traceback (most recent call last)
     File ~/error.py:4, in <module>
           1 def f():
           2     1/0
     ----> 4 f()
 
     File ~/error.py:2, in f()
           1 def f():
     ----> 2     1/0
 
 Many terminals and editors have integrations enabling you to directly jump to the
 relevant file/line when this syntax is used, so this small addition may have a high
 impact on productivity.
 
 
 Autosuggestions
 ~~~~~~~~~~~~~~~
 
 Autosuggestion is a very useful feature available in `fish <https://fishshell.com/>`__, `zsh <https://en.wikipedia.org/wiki/Z_shell>`__, and `prompt-toolkit <https://python-prompt-toolkit.readthedocs.io/en/master/pages/asking_for_input.html#auto-suggestion>`__.
 
 `Ptpython <https://github.com/prompt-toolkit/ptpython#ptpython>`__ allows users to enable this feature in
 `ptpython/config.py <https://github.com/prompt-toolkit/ptpython/blob/master/examples/ptpython_config/config.py#L90>`__.
 
 This feature allows users to accept autosuggestions with ctrl e, ctrl f,
 or right arrow as described below.
 
 1. Start ipython
 
 .. image:: ../_images/8.0/auto_suggest_1_prompt_no_text.png
 
 2. Run ``print("hello")``
 
 .. image:: ../_images/8.0/auto_suggest_2_print_hello_suggest.png
 
 3. start typing ``print`` again to see the autosuggestion
 
 .. image:: ../_images/8.0/auto_suggest_3_print_hello_suggest.png
 
 4. Press ``ctrl-f``, or ``ctrl-e``, or ``right-arrow`` to accept the suggestion
 
 .. image:: ../_images/8.0/auto_suggest_4_print_hello.png
 
 You can also complete word by word:
 
 1. Run ``def say_hello(): print("hello")``
 
 .. image:: ../_images/8.0/auto_suggest_second_prompt.png
 
 2. Start typing  the first letter if ``def`` to see the autosuggestion
 
 .. image:: ../_images/8.0/auto_suggest_d_phantom.png
 
 3. Press ``alt-f`` (or ``escape`` followed by ``f``), to accept the first word of the suggestion
 
 .. image:: ../_images/8.0/auto_suggest_def_phantom.png
 
 Importantly, this feature does not interfere with tab completion:
 
 1. After running ``def say_hello(): print("hello")``, press d
 
 .. image:: ../_images/8.0/auto_suggest_d_phantom.png
 
 2. Press Tab to start tab completion
 
 .. image:: ../_images/8.0/auto_suggest_d_completions.png
 
 3A. Press Tab again to select the first option
 
 .. image:: ../_images/8.0/auto_suggest_def_completions.png
 
 3B. Press ``alt f`` (``escape``, ``f``) to accept to accept the first word of the suggestion
 
 .. image:: ../_images/8.0/auto_suggest_def_phantom.png
 
 3C. Press ``ctrl-f`` or ``ctrl-e`` to accept the entire suggestion
 
 .. image:: ../_images/8.0/auto_suggest_match_parens.png
 
 
 Currently, autosuggestions are only shown in the emacs or vi insert editing modes:
 
 - The ctrl e, ctrl f, and alt f shortcuts work by default in emacs mode.
 - To use these shortcuts in vi insert mode, you will have to create `custom keybindings in your config.py <https://github.com/mskar/setup/commit/2892fcee46f9f80ef7788f0749edc99daccc52f4/>`__.
 
 
 Show pinfo information in ipdb using "?" and "??"
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 In IPDB, it is now possible to show the information about an object using "?"
 and "??", in much the same way that it can be done when using the IPython prompt::
 
     ipdb> partial?
     Init signature: partial(self, /, *args, **kwargs)
     Docstring:
     partial(func, *args, **keywords) - new function with partial application
     of the given arguments and keywords.
     File:           ~/.pyenv/versions/3.8.6/lib/python3.8/functools.py
     Type:           type
     Subclasses:
 
 Previously, ``pinfo`` or ``pinfo2`` command had to be used for this purpose.
 
 
 Autoreload 3 feature
 ~~~~~~~~~~~~~~~~~~~~
 
 Example: When an IPython session is run with the 'autoreload' extension loaded,
 you will now have the option '3' to select, which means the following:
 
     1. replicate all functionality from option 2
     2. autoload all new funcs/classes/enums/globals from the module when they are added
     3. autoload all newly imported funcs/classes/enums/globals from external modules
 
 Try ``%autoreload 3`` in an IPython session after running ``%load_ext autoreload``.
 
 For more information please see the following unit test : ``extensions/tests/test_autoreload.py:test_autoload_newly_added_objects``
 
 Auto formatting with black in the CLI
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 This feature was present in 7.x, but disabled by default.
 
 In 8.0, input was automatically reformatted with Black when black was installed.
 This feature has been reverted for the time being.
 You can re-enable it by setting ``TerminalInteractiveShell.autoformatter`` to ``"black"``
 
 History Range Glob feature
 ~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Previously, when using ``%history``, users could specify either
 a range of sessions and lines, for example:
 
 .. code-block:: python
 
    ~8/1-~6/5   # see history from the first line of 8 sessions ago,
                # to the fifth line of 6 sessions ago.``
 
 Or users could specify a glob pattern:
 
 .. code-block:: python
 
    -g <pattern>  # glob ALL history for the specified pattern.
 
 However users could *not* specify both.
 
 If a user *did* specify both a range and a glob pattern,
 then the glob pattern would be used (globbing *all* history) *and the range would be ignored*.
 
 With this enhancement, if a user specifies both a range and a glob pattern, then the glob pattern will be applied to the specified range of history.
 
 Don't start a multi-line cell with sunken parenthesis
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 From now on, IPython will not ask for the next line of input when given a single
 line with more closing than opening brackets. For example, this means that if
 you (mis)type ``]]`` instead of ``[]``, a ``SyntaxError`` will show up, instead of
 the ``...:`` prompt continuation.
 
 IPython shell for ipdb interact
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 The ipdb ``interact`` starts an IPython shell instead of Python's built-in ``code.interact()``.
 
 Automatic Vi prompt stripping
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 When pasting code into IPython, it will strip the leading prompt characters if
 there are any. For example, you can paste the following code into the console -
 it will still work, even though each line is prefixed with prompts (``In``,
 ``Out``)::
 
     In [1]: 2 * 2 == 4
     Out[1]: True
 
     In [2]: print("This still works as pasted")
 
 
 Previously, this was not the case for the Vi-mode prompts::
 
     In [1]: [ins] In [13]: 2 * 2 == 4
        ...: Out[13]: True
        ...:
       File "<ipython-input-1-727bb88eaf33>", line 1
         [ins] In [13]: 2 * 2 == 4
               ^
     SyntaxError: invalid syntax
 
 This is now fixed, and Vi prompt prefixes - ``[ins]`` and ``[nav]`` -  are
 skipped just as the normal ``In`` would be.
 
 IPython shell can be started in the Vi mode using ``ipython --TerminalInteractiveShell.editing_mode=vi``,
 You should be able to change mode dynamically with ``%config TerminalInteractiveShell.editing_mode='vi'``
 
 Empty History Ranges
 ~~~~~~~~~~~~~~~~~~~~
 
 A number of magics that take history ranges can now be used with an empty
 range. These magics are:
 
  * ``%save``
  * ``%load``
  * ``%pastebin``
  * ``%pycat``
 
 Using them this way will make them take the history of the current session up
 to the point of the magic call (such that the magic itself will not be
 included).
 
 Therefore it is now possible to save the whole history to a file using
 ``%save <filename>``, load and edit it using ``%load`` (makes for a nice usage
 when followed with :kbd:`F2`), send it to `dpaste.org <http://dpast.org>`_ using
 ``%pastebin``, or view the whole thing syntax-highlighted with a single
 ``%pycat``.
 
 
 Windows timing implementation: Switch to process_time
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Timing on Windows, for example with ``%%time``,  was changed from being based on ``time.perf_counter``
 (which counted time even when the process was sleeping) to being based on ``time.process_time`` instead
 (which only counts CPU time). This brings it closer to the behavior on Linux. See :ghpull:`12984`.
 
 Miscellaneous
 ~~~~~~~~~~~~~
  - Non-text formatters are not disabled in the terminal, which should simplify
    writing extensions displaying images or other mimetypes in supporting terminals.
    :ghpull:`12315`
  - It is now possible to automatically insert matching brackets in Terminal IPython using the
    ``TerminalInteractiveShell.auto_match=True`` option. :ghpull:`12586`
  - We are thinking of deprecating the current ``%%javascript`` magic in favor of a better replacement. See :ghpull:`13376`.
  - ``~`` is now expanded when part of a path in most magics :ghpull:`13385`
  - ``%/%%timeit`` magic now adds a comma every thousands to make reading a long number easier :ghpull:`13379`
  - ``"info"`` messages can now be customised to hide some fields :ghpull:`13343`
  - ``collections.UserList`` now pretty-prints :ghpull:`13320`
  - The debugger now has a persistent history, which should make it less
    annoying to retype commands :ghpull:`13246`
  - ``!pip`` ``!conda`` ``!cd`` or ``!ls`` are likely doing the wrong thing. We
    now warn users if they use one of those commands. :ghpull:`12954`
  - Make ``%precision`` work for ``numpy.float64`` type :ghpull:`12902`
 
 Re-added support for XDG config directories
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 XDG support through the years comes and goes. There is a tension between having
 an identical location for configuration in all platforms versus having simple instructions.
 After initial failures a couple of years ago, IPython was modified to automatically migrate XDG
 config files back into ``~/.ipython``. That migration code has now been removed.
 IPython now checks the XDG locations, so if you _manually_ move your config
 files to your preferred location, IPython will not move them back.
 
 
 Preparing for Python 3.10
 -------------------------
 
 To prepare for Python 3.10, we have started working on removing reliance and
 any dependency that is not compatible with Python 3.10. This includes migrating our
 test suite to pytest and starting to remove nose. This also means that the
 ``iptest`` command is now gone and all testing is via pytest.
 
 This was in large part thanks to the NumFOCUS Small Developer grant, which enabled us to
 allocate \$4000 to hire `Nikita Kniazev (@Kojoley) <https://github.com/Kojoley>`_,
 who did a fantastic job at updating our code base, migrating to pytest, pushing
 our coverage, and fixing a large number of bugs. I highly recommend contacting
 them if you need help with C++ and Python projects.
 
 You can find all relevant issues and PRs with `the SDG 2021 tag <https://github.com/ipython/ipython/issues?q=label%3A%22Numfocus+SDG+2021%22+>`__
 
 Removing support for older Python versions
 ------------------------------------------
 
 
 We are removing support for Python up through 3.7, allowing internal code to use the more
 efficient ``pathlib`` and to make better use of type annotations.
 
 .. image:: ../_images/8.0/pathlib_pathlib_everywhere.jpg
    :alt: "Meme image of Toy Story with Woody and Buzz, with the text 'pathlib, pathlib everywhere'"
 
 
 We had about 34 PRs only to update some logic to update some functions from managing strings to
 using Pathlib.
 
 The completer has also seen significant updates and now makes use of newer Jedi APIs,
 offering faster and more reliable tab completion.
