25 IPython 8.0 is bringing a number of new features and improvements to both the
26 user of the terminal and of the kernel via Jupyter. The removal of compatibility
27 with older version of Python is also the opportunity to do a couple of
28 performance improvement in particular with respect to startup time.
29
30 The main change in IPython 8.0 is the integration of the ``stack_data`` package;
31 which provide smarter information in traceback; in particular it will highlight
32 the AST node where an error occurs which can help to quickly narrow down errors.
33
34 For example in the following snippet::
35
36 def foo(i):
37 x = [[[0]]]
38 return x[0][i][0]
39
40
41 def bar():
42 return foo(0) + foo(
43 1
44 ) + foo(2)
45
46
47 Calling ``bar()`` would raise an ``IndexError`` on the return line of ``foo``,
48 IPython 8.0 is capable of telling you, where the index error occurs::
49
50 return x[0][i][0]
51 ^

53 To prepare for Python 3.10 we have also started working on removing reliance and
54 any dependency that is not Python 3.10 compatible; that include migrating our
55 test suite to Pytest, and starting to remove nose.
56
57 We are also removing support for Python 3.6 allowing internal code to use more
58 efficient ``pathlib``, and make better use of type annotations.
59
60 The completer has also seen significant updates and make use of newer Jedi API
61 offering faster and more reliable tab completion.
62
63 For the terminal users this also enable the auto-suggestion feature, described
64 below, which show "ghost text" ahead of your cursor you can accept without
65 having to press the tab key or ask the completer to suggest completions.

27 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>`__.
