10 10 Second release of IPython in 2023, last Friday of the month, we are back on
11 11 track. This is a small release with a few bug-fixes, and improvements, mostly
12 12 with respect to terminal shortcuts.

15 The biggest improvement for 8.9 is a drastic amelioration of the
16 16 auto-suggestions sponsored by D.E. Shaw and implemented by the more and more
17 17 active contributor `@krassowski <https://github.com/krassowski>`.
18 18
19 19 - ``right`` accepts a single character from suggestion
20 20 - ``ctrl+right`` accepts a semantic token (macos default shortcuts take
21 21 precedence and need to be disabled to make this work)
22 22 - ``backspace`` deletes a character and resumes hinting autosuggestions
23 23 - ``ctrl-left`` accepts suggestion and moves cursor left one character.
24 24 - ``backspace`` deletes a character and resumes hinting autosuggestions
25 25 - ``down`` moves to suggestion to later in history when no lines are present below the cursors.
26 26 - ``up`` moves to suggestion from earlier in history when no lines are present above the cursor.

67 67 completion, in particular for dictionary keys.
68 68 - :ghpull:`13858` that adds ``py.typed`` to ``setup.cfg`` to make sure it is
69 69 bundled in wheels.
70 70 - :ghpull:`13869` that implements tab completions for IPython options in the
71 71 shell when using `argcomplete <https://github.com/kislyuk/argcomplete>`. I
72 72 believe this also needs a recent version of Traitlets.
73 73 - :ghpull:`13865` makes the ``inspector`` class of `InteractiveShell`
74 74 configurable.

79 79 In no particular order, the rest of the changes update the test suite to be
80 80 compatible with Pygments 2.14, various docfixes, testing on more recent python
81 81 versions and various updates.

143 143 The color of error nodes in tracebacks can now be customized. See
144 :ghpull:`13756`. This is a private attribute until someone find the time to
145 properly add a configuration option. Note that with Python 3.11 that also show
146 the relevant nodes in traceback, it would be good to leverage this informations

148 148 I won't have time to do before long, so contributions welcome.

150 150 As we follow NEP 29, we removed support for numpy 1.19 :ghpull:`13760`.
151 151
152 152
153 153 The ``open()`` function present in the user namespace by default will now refuse
154 154 to open the file descriptors 0,1,2 (stdin, out, err), to avoid crashing IPython.
155 155 This mostly occurs in teaching context when incorrect values get passed around.

420 420 We want to remind users that IPython is part of the Jupyter organisations, and
421 421 thus governed by a Code of Conduct. Some of the behavior we have seen on GitHub is not acceptable.
422 422 Abuse and non-respectful comments on discussion will not be tolerated.

424 Many thanks to all the contributors to this release, many of the above fixed issues and
425 new features were done by first time contributors, showing there is still
426 426 plenty of easy contribution possible in IPython
427 427 . You can find all individual contributions
428 428 to this milestone `on github <https://github.com/ipython/ipython/milestone/91>`__.
429 429
430 430 Thanks as well to the `D. E. Shaw group <https://deshaw.com/>`__ for sponsoring
431 431 work on IPython and related libraries. In particular the Lazy autoloading of
432 432 magics that you will find described in the 7.32 release notes.

434 434
435 435 .. _version 8.0.1:
436 436
437 437 IPython 8.0.1 (CVE-2022-21699)
438 438 ------------------------------
439 439
440 440 IPython 8.0.1, 7.31.1 and 5.11 are security releases that change some default
441 441 values in order to prevent potential Execution with Unnecessary Privileges.
442 442
443 443 Almost all version of IPython looks for configuration and profiles in current
444 444 working directory. Since IPython was developed before pip and environments
445 445 existed it was used a convenient way to load code/packages in a project
446 446 dependant way.
447 447
448 448 In 2022, it is not necessary anymore, and can lead to confusing behavior where
449 449 for example cloning a repository and starting IPython or loading a notebook from
450 450 any Jupyter-Compatible interface that has ipython set as a kernel can lead to
451 451 code execution.
452 452
453 453
454 454 I did not find any standard way for packaged to advertise CVEs they fix, I'm
455 455 thus trying to add a ``__patched_cves__`` attribute to the IPython module that
456 456 list the CVEs that should have been fixed. This attribute is informational only
457 457 as if a executable has a flaw, this value can always be changed by an attacker.
458 458
459 459 .. code::
460 460
461 461 In [1]: import IPython
462 462
463 463 In [2]: IPython.__patched_cves__
464 464 Out[2]: {'CVE-2022-21699'}
465 465
466 466 In [3]: 'CVE-2022-21699' in IPython.__patched_cves__
467 467 Out[3]: True
468 468
469 469 Thus starting with this version:
470 470
471 471 - The current working directory is not searched anymore for profiles or
472 472 configurations files.
473 473 - Added a ``__patched_cves__`` attribute (set of strings) to IPython module that contain
474 474 the list of fixed CVE. This is informational only.

479 479 .. _version 8.0:
480 480
481 481 IPython 8.0
482 482 -----------
483 483
484 484 IPython 8.0 is bringing a large number of new features and improvements to both the
485 485 user of the terminal and of the kernel via Jupyter. The removal of compatibility
486 with older version of Python is also the opportunity to do a couple of
486 with an older version of Python is also the opportunity to do a couple of
487 487 performance improvements in particular with respect to startup time.
488 488 The 8.x branch started diverging from its predecessor around IPython 7.12
489 489 (January 2020).
490 490
491 491 This release contains 250+ pull requests, in addition to many of the features
492 492 and backports that have made it to the 7.x branch. Please see the
493 493 `8.0 milestone <https://github.com/ipython/ipython/milestone/73?closed=1>`__ for the full list of pull requests.
494 494
495 Please feel free to send pull requests to updates those notes after release,
495 Please feel free to send pull requests to update those notes after release,

498 498 Dependencies changes/downstream packaging
499 499 -----------------------------------------
500 500
501 501 Most of our building steps have been changed to be (mostly) declarative
502 502 and follow PEP 517. We are trying to completely remove ``setup.py`` (:ghpull:`13238`) and are
503 503 looking for help to do so.
504 504
505 505 - minimum supported ``traitlets`` version is now 5+
506 506 - we now require ``stack_data``
507 507 - minimal Python is now 3.8
508 508 - ``nose`` is not a testing requirement anymore
509 509 - ``pytest`` replaces nose.
510 - ``iptest``/``iptest3`` cli entrypoints do not exists anymore.
511 - minimum officially support ``numpy`` version has been bumped, but this should
510 - ``iptest``/``iptest3`` cli entrypoints do not exist anymore.
511 - the minimum officially supported ``numpy`` version has been bumped, but this should
512 512 not have much effect on packaging.
513 513
514 514
515 515 Deprecation and removal
516 516 -----------------------
517 517
518 518 We removed almost all features, arguments, functions, and modules that were
519 519 marked as deprecated between IPython 1.0 and 5.0. As a reminder, 5.0 was released
520 520 in 2016, and 1.0 in 2013. Last release of the 5 branch was 5.10.0, in May 2020.
521 521 The few remaining deprecated features we left have better deprecation warnings
522 522 or have been turned into explicit errors for better error messages.
523 523
524 524 I will use this occasion to add the following requests to anyone emitting a
525 525 deprecation warning:
526 526
527 527 - Please add at least ``stacklevel=2`` so that the warning is emitted into the
528 528 caller context, and not the callee one.
529 529 - Please add **since which version** something is deprecated.
530 530
531 531 As a side note, it is much easier to conditionally compare version
532 532 numbers rather than using ``try/except`` when functionality changes with a version.
533 533
534 534 I won't list all the removed features here, but modules like ``IPython.kernel``,
535 535 which was just a shim module around ``ipykernel`` for the past 8 years, have been
536 536 removed, and so many other similar things that pre-date the name **Jupyter**
537 537 itself.
538 538
539 539 We no longer need to add ``IPython.extensions`` to the PYTHONPATH because that is being
540 540 handled by ``load_extension``.
541 541
542 542 We are also removing ``Cythonmagic``, ``sympyprinting`` and ``rmagic`` as they are now in
543 543 other packages and no longer need to be inside IPython.
544 544
545 545
546 546 Documentation
547 547 -------------
548 548
549 549 The majority of our docstrings have now been reformatted and automatically fixed by
550 550 the experimental `Vélin <https://pypi.org/project/velin/>`_ project to conform
551 551 to numpydoc.
552 552
553 553 Type annotations
554 554 ----------------
555 555
556 556 While IPython itself is highly dynamic and can't be completely typed, many of
557 557 the functions now have type annotations, and part of the codebase is now checked
558 558 by mypy.
559 559
560 560
561 561 Featured changes
562 562 ----------------
563 563
564 564 Here is a features list of changes in IPython 8.0. This is of course non-exhaustive.
565 565 Please note as well that many features have been added in the 7.x branch as well
566 566 (and hence why you want to read the 7.x what's new notes), in particular
567 567 features contributed by QuantStack (with respect to debugger protocol and Xeus
568 568 Python), as well as many debugger features that I was pleased to implement as
569 569 part of my work at QuanSight and sponsored by DE Shaw.
570 570
571 571 Traceback improvements
572 572 ~~~~~~~~~~~~~~~~~~~~~~
573 573
574 574 Previously, error tracebacks for errors happening in code cells were showing a
575 575 hash, the one used for compiling the Python AST::
576 576
577 577 In [1]: def foo():
578 578 ...: return 3 / 0
579 579 ...:
580 580
581 581 In [2]: foo()
582 582 ---------------------------------------------------------------------------
583 583 ZeroDivisionError Traceback (most recent call last)
584 584 <ipython-input-2-c19b6d9633cf> in <module>
585 585 ----> 1 foo()
586 586
587 587 <ipython-input-1-1595a74c32d5> in foo()
588 588 1 def foo():
589 589 ----> 2 return 3 / 0
590 590 3
591 591
592 592 ZeroDivisionError: division by zero
593 593
594 594 The error traceback is now correctly formatted, showing the cell number in which the error happened::
595 595
596 596 In [1]: def foo():
597 597 ...: return 3 / 0
598 598 ...:
599 599
600 600 Input In [2]: foo()
601 601 ---------------------------------------------------------------------------
602 602 ZeroDivisionError Traceback (most recent call last)
603 603 input In [2], in <module>
604 604 ----> 1 foo()
605 605
606 606 Input In [1], in foo()
607 607 1 def foo():
608 608 ----> 2 return 3 / 0
609 609
610 610 ZeroDivisionError: division by zero
611 611
612 612 The ``stack_data`` package has been integrated, which provides smarter information in the traceback;
613 613 in particular it will highlight the AST node where an error occurs which can help to quickly narrow down errors.
614 614
615 615 For example in the following snippet::
616 616
617 617 def foo(i):
618 618 x = [[[0]]]
619 619 return x[0][i][0]
620 620
621 621
622 622 def bar():
623 623 return foo(0) + foo(
624 624 1
625 625 ) + foo(2)
626 626
627 627
628 628 calling ``bar()`` would raise an ``IndexError`` on the return line of ``foo``,
629 629 and IPython 8.0 is capable of telling you where the index error occurs::
630 630
631 631
632 632 IndexError
633 633 Input In [2], in <module>
634 634 ----> 1 bar()
635 635 ^^^^^
636 636
637 637 Input In [1], in bar()
638 638 6 def bar():
639 639 ----> 7 return foo(0) + foo(
640 640 ^^^^
641 641 8 1
642 642 ^^^^^^^^
643 643 9 ) + foo(2)
644 644 ^^^^
645 645
646 646 Input In [1], in foo(i)
647 647 1 def foo(i):
648 648 2 x = [[[0]]]
649 649 ----> 3 return x[0][i][0]
650 650 ^^^^^^^
651 651
652 652 The corresponding locations marked here with ``^`` will show up highlighted in
653 653 the terminal and notebooks.
654 654
655 655 Finally, a colon ``::`` and line number is appended after a filename in
656 656 traceback::
657 657
658 658
659 659 ZeroDivisionError Traceback (most recent call last)
660 660 File ~/error.py:4, in <module>
661 661 1 def f():
662 662 2 1/0
663 663 ----> 4 f()
664 664
665 665 File ~/error.py:2, in f()
666 666 1 def f():
667 667 ----> 2 1/0
668 668
669 669 Many terminals and editors have integrations enabling you to directly jump to the
670 670 relevant file/line when this syntax is used, so this small addition may have a high
671 671 impact on productivity.
672 672
673 673
674 674 Autosuggestions
675 675 ~~~~~~~~~~~~~~~
676 676
677 677 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>`__.
678 678
679 679 `Ptpython <https://github.com/prompt-toolkit/ptpython#ptpython>`__ allows users to enable this feature in
680 680 `ptpython/config.py <https://github.com/prompt-toolkit/ptpython/blob/master/examples/ptpython_config/config.py#L90>`__.
681 681
682 682 This feature allows users to accept autosuggestions with ctrl e, ctrl f,
683 683 or right arrow as described below.
684 684
685 685 1. Start ipython
686 686
687 687 .. image:: ../_images/8.0/auto_suggest_1_prompt_no_text.png
688 688
689 689 2. Run ``print("hello")``
690 690
691 691 .. image:: ../_images/8.0/auto_suggest_2_print_hello_suggest.png
692 692
693 693 3. start typing ``print`` again to see the autosuggestion
694 694
695 695 .. image:: ../_images/8.0/auto_suggest_3_print_hello_suggest.png
696 696
697 697 4. Press ``ctrl-f``, or ``ctrl-e``, or ``right-arrow`` to accept the suggestion
698 698
699 699 .. image:: ../_images/8.0/auto_suggest_4_print_hello.png
700 700
701 701 You can also complete word by word:
702 702
703 703 1. Run ``def say_hello(): print("hello")``
704 704
705 705 .. image:: ../_images/8.0/auto_suggest_second_prompt.png
706 706
707 707 2. Start typing the first letter if ``def`` to see the autosuggestion
708 708
709 709 .. image:: ../_images/8.0/auto_suggest_d_phantom.png
710 710
711 711 3. Press ``alt-f`` (or ``escape`` followed by ``f``), to accept the first word of the suggestion
712 712
713 713 .. image:: ../_images/8.0/auto_suggest_def_phantom.png
714 714
715 715 Importantly, this feature does not interfere with tab completion:
716 716
717 717 1. After running ``def say_hello(): print("hello")``, press d
718 718
719 719 .. image:: ../_images/8.0/auto_suggest_d_phantom.png
720 720
721 721 2. Press Tab to start tab completion
722 722
723 723 .. image:: ../_images/8.0/auto_suggest_d_completions.png
724 724
725 725 3A. Press Tab again to select the first option
726 726
727 727 .. image:: ../_images/8.0/auto_suggest_def_completions.png
728 728
729 729 3B. Press ``alt f`` (``escape``, ``f``) to accept to accept the first word of the suggestion
730 730
731 731 .. image:: ../_images/8.0/auto_suggest_def_phantom.png
732 732
733 733 3C. Press ``ctrl-f`` or ``ctrl-e`` to accept the entire suggestion
734 734
735 735 .. image:: ../_images/8.0/auto_suggest_match_parens.png
736 736
737 737
738 738 Currently, autosuggestions are only shown in the emacs or vi insert editing modes:
739 739
740 740 - The ctrl e, ctrl f, and alt f shortcuts work by default in emacs mode.
741 741 - 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/>`__.
742 742
743 743
744 744 Show pinfo information in ipdb using "?" and "??"
745 745 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
746 746
747 747 In IPDB, it is now possible to show the information about an object using "?"
748 748 and "??", in much the same way that it can be done when using the IPython prompt::
749 749
750 750 ipdb> partial?
751 751 Init signature: partial(self, /, *args, **kwargs)
752 752 Docstring:
753 753 partial(func, *args, **keywords) - new function with partial application
754 754 of the given arguments and keywords.
755 755 File: ~/.pyenv/versions/3.8.6/lib/python3.8/functools.py
756 756 Type: type
757 757 Subclasses:
758 758
759 759 Previously, ``pinfo`` or ``pinfo2`` command had to be used for this purpose.
760 760
761 761
762 762 Autoreload 3 feature
763 763 ~~~~~~~~~~~~~~~~~~~~
764 764
765 765 Example: When an IPython session is run with the 'autoreload' extension loaded,
766 766 you will now have the option '3' to select, which means the following:
767 767
768 768 1. replicate all functionality from option 2
769 769 2. autoload all new funcs/classes/enums/globals from the module when they are added
770 770 3. autoload all newly imported funcs/classes/enums/globals from external modules
771 771
772 772 Try ``%autoreload 3`` in an IPython session after running ``%load_ext autoreload``.
773 773
774 774 For more information please see the following unit test : ``extensions/tests/test_autoreload.py:test_autoload_newly_added_objects``
775 775
776 776 Auto formatting with black in the CLI
777 777 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
778 778
779 779 This feature was present in 7.x, but disabled by default.
780 780
781 781 In 8.0, input was automatically reformatted with Black when black was installed.
782 782 This feature has been reverted for the time being.
783 783 You can re-enable it by setting ``TerminalInteractiveShell.autoformatter`` to ``"black"``
784 784
785 785 History Range Glob feature
786 786 ~~~~~~~~~~~~~~~~~~~~~~~~~~
787 787
788 788 Previously, when using ``%history``, users could specify either
789 789 a range of sessions and lines, for example:
790 790
791 791 .. code-block:: python
792 792
793 793 ~8/1-~6/5 # see history from the first line of 8 sessions ago,
794 794 # to the fifth line of 6 sessions ago.``
795 795
796 796 Or users could specify a glob pattern:
797 797
798 798 .. code-block:: python
799 799
800 800 -g <pattern> # glob ALL history for the specified pattern.
801 801
802 802 However users could *not* specify both.
803 803
804 804 If a user *did* specify both a range and a glob pattern,
805 805 then the glob pattern would be used (globbing *all* history) *and the range would be ignored*.
806 806
807 807 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.
808 808
809 809 Don't start a multi-line cell with sunken parenthesis
810 810 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
811 811
812 812 From now on, IPython will not ask for the next line of input when given a single
813 813 line with more closing than opening brackets. For example, this means that if
814 814 you (mis)type ``]]`` instead of ``[]``, a ``SyntaxError`` will show up, instead of
815 815 the ``...:`` prompt continuation.
816 816
817 817 IPython shell for ipdb interact
818 818 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
819 819
820 820 The ipdb ``interact`` starts an IPython shell instead of Python's built-in ``code.interact()``.
821 821
822 822 Automatic Vi prompt stripping
823 823 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
824 824
825 825 When pasting code into IPython, it will strip the leading prompt characters if
826 826 there are any. For example, you can paste the following code into the console -
827 827 it will still work, even though each line is prefixed with prompts (``In``,
828 828 ``Out``)::
829 829
830 830 In [1]: 2 * 2 == 4
831 831 Out[1]: True
832 832
833 833 In [2]: print("This still works as pasted")
834 834
835 835
836 836 Previously, this was not the case for the Vi-mode prompts::
837 837
838 838 In [1]: [ins] In [13]: 2 * 2 == 4
839 839 ...: Out[13]: True
840 840 ...:
841 841 File "<ipython-input-1-727bb88eaf33>", line 1
842 842 [ins] In [13]: 2 * 2 == 4
843 843 ^
844 844 SyntaxError: invalid syntax
845 845
846 846 This is now fixed, and Vi prompt prefixes - ``[ins]`` and ``[nav]`` - are
847 847 skipped just as the normal ``In`` would be.
848 848
849 849 IPython shell can be started in the Vi mode using ``ipython --TerminalInteractiveShell.editing_mode=vi``,
850 850 You should be able to change mode dynamically with ``%config TerminalInteractiveShell.editing_mode='vi'``
851 851
852 852 Empty History Ranges
853 853 ~~~~~~~~~~~~~~~~~~~~
854 854
855 855 A number of magics that take history ranges can now be used with an empty
856 856 range. These magics are:
857 857
858 858 * ``%save``
859 859 * ``%load``
860 860 * ``%pastebin``
861 861 * ``%pycat``
862 862
863 863 Using them this way will make them take the history of the current session up
864 864 to the point of the magic call (such that the magic itself will not be
865 865 included).
866 866
867 867 Therefore it is now possible to save the whole history to a file using
868 868 ``%save <filename>``, load and edit it using ``%load`` (makes for a nice usage
869 869 when followed with :kbd:`F2`), send it to `dpaste.org <http://dpast.org>`_ using
870 870 ``%pastebin``, or view the whole thing syntax-highlighted with a single
871 871 ``%pycat``.
872 872
873 873
874 874 Windows timing implementation: Switch to process_time
875 875 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
876 876 Timing on Windows, for example with ``%%time``, was changed from being based on ``time.perf_counter``
877 877 (which counted time even when the process was sleeping) to being based on ``time.process_time`` instead
878 878 (which only counts CPU time). This brings it closer to the behavior on Linux. See :ghpull:`12984`.
879 879
880 880 Miscellaneous
881 881 ~~~~~~~~~~~~~
882 882 - Non-text formatters are not disabled in the terminal, which should simplify
883 883 writing extensions displaying images or other mimetypes in supporting terminals.
884 884 :ghpull:`12315`
885 885 - It is now possible to automatically insert matching brackets in Terminal IPython using the
886 886 ``TerminalInteractiveShell.auto_match=True`` option. :ghpull:`12586`
887 887 - We are thinking of deprecating the current ``%%javascript`` magic in favor of a better replacement. See :ghpull:`13376`.
888 888 - ``~`` is now expanded when part of a path in most magics :ghpull:`13385`
889 889 - ``%/%%timeit`` magic now adds a comma every thousands to make reading a long number easier :ghpull:`13379`
890 890 - ``"info"`` messages can now be customised to hide some fields :ghpull:`13343`
891 891 - ``collections.UserList`` now pretty-prints :ghpull:`13320`
892 892 - The debugger now has a persistent history, which should make it less
893 893 annoying to retype commands :ghpull:`13246`
894 894 - ``!pip`` ``!conda`` ``!cd`` or ``!ls`` are likely doing the wrong thing. We
895 895 now warn users if they use one of those commands. :ghpull:`12954`
896 896 - Make ``%precision`` work for ``numpy.float64`` type :ghpull:`12902`
897 897
898 898 Re-added support for XDG config directories
899 899 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
900 900
901 901 XDG support through the years comes and goes. There is a tension between having
902 902 an identical location for configuration in all platforms versus having simple instructions.
903 903 After initial failures a couple of years ago, IPython was modified to automatically migrate XDG
904 904 config files back into ``~/.ipython``. That migration code has now been removed.
905 905 IPython now checks the XDG locations, so if you _manually_ move your config
906 906 files to your preferred location, IPython will not move them back.
907 907
908 908
909 909 Preparing for Python 3.10
910 910 -------------------------
911 911
912 912 To prepare for Python 3.10, we have started working on removing reliance and
913 913 any dependency that is not compatible with Python 3.10. This includes migrating our
914 914 test suite to pytest and starting to remove nose. This also means that the
915 915 ``iptest`` command is now gone and all testing is via pytest.
916 916
917 917 This was in large part thanks to the NumFOCUS Small Developer grant, which enabled us to
918 918 allocate \$4000 to hire `Nikita Kniazev (@Kojoley) <https://github.com/Kojoley>`_,
919 919 who did a fantastic job at updating our code base, migrating to pytest, pushing
920 920 our coverage, and fixing a large number of bugs. I highly recommend contacting
921 921 them if you need help with C++ and Python projects.
922 922
923 923 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+>`__
924 924
925 925 Removing support for older Python versions
926 926 ------------------------------------------
927 927
928 928
929 929 We are removing support for Python up through 3.7, allowing internal code to use the more
930 930 efficient ``pathlib`` and to make better use of type annotations.
931 931
932 932 .. image:: ../_images/8.0/pathlib_pathlib_everywhere.jpg
933 933 :alt: "Meme image of Toy Story with Woody and Buzz, with the text 'pathlib, pathlib everywhere'"
934 934
935 935
936 936 We had about 34 PRs only to update some logic to update some functions from managing strings to
937 937 using Pathlib.
938 938
939 939 The completer has also seen significant updates and now makes use of newer Jedi APIs,
940 940 offering faster and more reliable tab completion.
