8.x Series
IPython 8.9.1
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.
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`.
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.
As we follow NEP29, next version of IPython will officially stop supporting numpy 1.20, and will stop supporting Python 3.8 after April release.
As usual you can find the full list of PRs on GitHub under the 8.9 milestone.
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
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.
Many thanks to @krassowski for the many PRs and @jasongrout for reviewing and merging contributions.
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
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.
- :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 for sponsoring work on IPython and related libraries.
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.
As usual you can find the full list of PRs on GitHub under the 8.6 milestone.
Thanks to all hacktoberfest contributors, please contribute to closember.org.
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
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.
- 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).
:ghpull:`13706`
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
IPython 8.4.0
As for 7.34, this version contains a single fix: fix uncaught BdbQuit exceptions on ipdb exit :ghpull:`13668`, and a single typo fix in documentation: :ghpull:`13682`
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
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.
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.
All the issues on pull-requests for this release can be found in the 8.2 milestone. . And some documentation only PR can be found as part of the 7.33 milestone (currently not released).
Thanks to the D. E. Shaw group for sponsoring work on IPython and related libraries.
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`.
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 formating 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.
Thanks as well to the D. E. Shaw group 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.
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.
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
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 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 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, zsh, and prompt-toolkit.
Ptpython allows users to enable this feature in ptpython/config.py.
This feature allows users to accept autosuggestions with ctrl e, ctrl f, or right arrow as described below.
- Start ipython
- Run print("hello")
- start typing print again to see the autosuggestion
- Press ctrl-f, or ctrl-e, or right-arrow to accept the suggestion
You can also complete word by word:
- Run def say_hello(): print("hello")
- Start typing the first letter if def to see the autosuggestion
- Press alt-f (or escape followed by f), to accept the first word of the suggestion
Importantly, this feature does not interfere with tab completion:
- After running def say_hello(): print("hello"), press d
- Press Tab to start tab completion
3A. Press Tab again to select the first option
3B. Press alt f (escape, f) to accept to accept the first word of the suggestion
3C. Press ctrl-f or ctrl-e to accept the entire suggestion
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.
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:
- replicate all functionality from option 2
- autoload all new funcs/classes/enums/globals from the module when they are added
- 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:
~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:
-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 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), 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
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.
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.
