py-ipython: updated to 7.23.0

IPython 7.23
============
Third release of IPython for 2021, mostly containing bug fixes. A couple of not
typical updates:

 - We moved to GitHub actions away from Travis-CI, the transition may not be
   100% complete (not testing on nightly anymore), but as we ran out of
   Travis-Ci hours on the IPython organisation that was a necessary step.
   :ghpull:`12900`.

 - We have a new dependency: ``matplotlib-inline``, which try to extract
   matplotlib inline backend specific behavior. It is available on PyPI and
   conda-forge thus should not be a problem to upgrade to this version. If you
   are a package maintainer that might be an extra dependency to package first.
   :ghpull:`12817`

In the addition/new feature category, ``display()`` now have a ``clear=True``
option to clear the display if any further outputs arrives, allowing users to
avoid having to use ``clear_output()`` directly. :ghpull:`12823`.

In bug fixes category, this release fix an issue when printing tracebacks
containing Unicode characters :ghpull:`12758`.

In code cleanup category :ghpull:`12932` remove usage of some deprecated
functionality for compatibility with Python 3.10.

IPython 7.22
============
Second release of IPython for 2021, mostly containing bug fixes. Here is a quick
rundown of the few changes.

- Fix some ``sys.excepthook`` shenanigan when embedding with qt, recommended if
  you – for example – use `napari <https://napari.org>`__. :ghpull:`12842`.
- Fix bug when using the new ipdb ``%context`` magic :ghpull:`12844`
- Couples of deprecation cleanup :ghpull:`12868`
- Update for new dpast.com api if you use the ``%pastbin`` magic. :ghpull:`12712`
- Remove support for numpy before 1.16. :ghpull:`12836`

IPython 7.21
============
IPython 7.21 is the first release we have back on schedule of one release every
month; it contains a number of minor fixes and improvements, notably, the new
context command for ipdb

New "context" command in ipdb
-----------------------------
It is now possible to change the number of lines shown in the backtrace
information in ipdb using "context" command. :ghpull:`12826`

Other notable changes in IPython 7.21
-------------------------------------
- Fix some issues on new osx-arm64 :ghpull:`12804`, :ghpull:`12807`.
- Compatibility with Xeus-Python for debugger protocol, :ghpull:`12809`
- Misc docs fixes for compatibility and uniformity with Numpydoc.

IPython 7.20
============

IPython 7.20 is the accumulation of 3 month of work on IPython, spacing between
IPython release have been increased from the usual once a month for various
reason.

   - Mainly as I'm too busy and the effectively sole maintainer, and
   - Second because not much changes happened before mid December.

The main driver for this release was the new version of Jedi 0.18 breaking API;
which was taken care of in the master branch early in 2020 but not in 7.x as I
though that by now 8.0 would be out.

The inclusion of a resolver in pip did not help and actually made things worse.
If usually I would have simply pinned Jedi to ``<0.18``; this is not a solution
anymore as now pip is free to install Jedi 0.18, and downgrade IPython.

I'll do my best to keep the regular release, but as the 8.0-dev branch and 7.x
are starting to diverge this is becoming difficult in particular with my limited
time, so if you have any cycles to spare I'll appreciate your help to respond to
issues and pushing 8.0 forward.

Here are thus some of the changes for IPython 7.20.

  - Support for PyQt5 >= 5.11 :ghpull:`12715`
  - ``%reset`` remove imports more agressively :ghpull:`12718`
  - fix the ``%conda`` magic :ghpull:`12739`
  - compatibility with Jedi 0.18, and bump minimum Jedi version. :ghpull:`12793`

Log message:
py-ipython: updated to 7.19.0

IPython 7.19 accumulative two month of works, bug fixes and improvements, there
was exceptionally no release last month.

- Fix to restore the ability to specify more than one extension using command
  line flags when using traitlets 5.0
- Docs docs formatting that make the install commands work on zsh
- Always display the last frame in tracebacks even if hidden with
  ``__traceback_hide__``
- Avoid an issue where a callback can be registered multiple times.
- Avoid an issue in debugger mode where frames changes could be lost.
- Never hide the frames that invoke a debugger, even if marked as hidden by
  ``__traceback_hide__``
- Fix calling the debugger in a recursive manner

Log message:
py-ipython: updated to 7.18.1

IPython 7.18 is a minor release that mostly contains bugfixes.

 - ``CRLF`` is now handled by magics my default; solving some issues due to copy
   pasting on windows.

 - Requiring pexpect ``>=4.3`` as we are Python 3.7+ only and earlier version of
   pexpect will be incompatible.

 - Minimum jedi version is now 0.16.

Log message:
*: switch to versioned_dependencies.mk for py-setuptools

Log message:
No longer supports Python 3.6

Log message:
py-ipython: updated to 7.17.0

IPython 7.17
============

IPython 7.17 brings a couple of new improvements to API and a couple of user
facing changes to make the terminal experience more user friendly.

:ghpull:`12407` introduces the ability to pass extra argument to the IPython
debugger class; this is to help a new project from ``kmaork``
(https://github.com/kmaork/madbg) to feature a fully remote debugger.

:ghpull:`12410` finally remove support for 3.6, while the codebase is still
technically compatible; IPython will not install on Python 3.6.

lots of work on the debugger and hidden frames from ``@impact27`` in
:ghpull:`12437`, :ghpull:`12445`, :ghpull:`12460` and in particular
:ghpull:`12453` which make the debug magic more robust at handling spaces.

Biggest API addition is code transformation which is done before code execution;
IPython allows a number of hooks to catch non-valid Python syntax (magic, prompt
stripping...etc). Transformers are usually called many time; typically:

 - When trying to figure out whether the code is complete and valid (should we
   insert a new line or execute ?)
 - During actual code execution pass before giving the code to Python's
   ``exec``.

This lead to issues when transformer might have had side effects; or do external
queries. Starting with IPython 7.17 you can expect your transformer to be called
less time.

Input transformers are now called only once in the execution path of
`InteractiveShell`, allowing to register transformer that potentially have side
effects (note that this is not recommended). Internal methods `should_run_async`, and
`run_cell_async` now take a recommended optional `transformed_cell`, and
`preprocessing_exc_tuple` parameters that will become mandatory at some point in
the future; that is to say cells need to be explicitly transformed to be valid
Python syntax ahead of trying to run them. :ghpull:`12440`;

``input_transformers`` can now also have an attribute ``has_side_effects`` set
to `True`, when this attribute is present; this  will prevent the transformers
from being ran when IPython is trying to guess whether the user input is
complete. Note that this may means you will need to explicitly execute in some
case where your transformations are now not ran; but will not affect users with
no custom extensions.

py-ipython: updated to 7.16.1

IPython 7.16
============

The default traceback mode will now skip frames that are marked with
``__tracebackhide__ = True`` and show how many traceback frames have been
skipped. This can be toggled by using :magic:`xmode` with the ``--show`` or
``--hide`` attribute. It will have no effect on non verbose traceback modes.

The ipython debugger also now understands ``__tracebackhide__`` as well and will
skip hidden frames when displaying. Movement up and down the stack will skip the
hidden frames and will show how many frames were hidden. Internal IPython frames
are also now hidden by default. The behavior can be changed with the
``skip_hidden`` while in the debugger, command and accepts "yes", \ 
"no", "true"
and "false" case insensitive parameters.

Misc Noticeable changes:
------------------------
- Exceptions are now (re)raised when running notebooks via the :magic:`%run`, \ 
helping to catch issues in workflows and
  pipelines. :ghpull:`12301`
- Fix inputhook for qt 5.15.0 :ghpull:`12355`
- Fix wx inputhook :ghpull:`12375`
- Add handling for malformed pathext env var (Windows) :ghpull:`12367`
- use $SHELL in system_piped :ghpull:`12360` for uniform behavior with
  ipykernel.

Log message:
*: Remove manual page entries from ALTERNATIVES files.

Thes are not supported by pkg_alternatives, and lead to breakage as found
in <http://mail-index.netbsd.org/tech-pkg/2020/05/06/msg023089.html>.

In many cases these were unnecessary anyway, as they match the corresponding
command that pkg_alternatives will have automatically detected manual page
entries for, plus many of them did not support PKGMANDIR.

In the one case (databases/py-peewee) where the manual page does not match
the command name, pkg_alternatives will need to be enhanced to support this
before it can be re-enabled.
