Changes in IPython kernel
=========================
4.6
---
4.6.1
*****
`4.6.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.6.1>`__
- Fix eventloop-integration bug preventing Qt windows/widgets from displaying with ipykernel 4.6.0 and IPython ≥ 5.2.
- Avoid deprecation warnings about naive datetimes when working with jupyter_client ≥ 5.0.
4.6.0
*****
`4.6.0 on GitHub <https://github.com/ipython/ipykernel/milestones/4.6>`__
- Add to API `DisplayPublisher.publish` two new fully backward-compatible
keyword-args:
- `update: bool`
- `transient: dict`
- Support new `transient` key in `display_data` messages spec for `publish`.
For a display data message, `transient` contains data that shouldn't be
persisted to files or documents. Add a `display_id` to this `transient`
dict by `display(obj, display_id=...)`
- Add `ipykernel_launcher` module which removes the current working directory
from `sys.path` before launching the kernel. This helps to reduce the cases
where the kernel won't start because there's a `random.py` (or similar)
module in the current working directory.
- Add busy/idle messages on IOPub during processing of aborted requests
- Add active event loop setting to GUI, which enables the correct response
to IPython's `is_event_loop_running_xxx`
- Include IPython kernelspec in wheels to reduce reliance on "native kernel
spec" in jupyter_client
- Modify `OutStream` to inherit from `TextIOBase` instead of object to improve
API support and error reporting
- Fix IPython kernel death messages at start, such as "Kernel Restarting..."
and "Kernel appears to have died", when parent-poller handles PID 1
- Various bugfixes
4.5
---
4.5.2
*****
`4.5.2 on GitHub <https://github.com/ipython/ipykernel/milestones/4.5.2>`__
- Fix bug when instantiating Comms outside of the IPython kernel (introduced in 4.5.1).
4.5.1
*****
`4.5.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.5.1>`__
- Add missing ``stream`` parameter to overridden :func:`getpass`
- Remove locks from iopub thread, which could cause deadlocks during debugging
- Fix regression where KeyboardInterrupt was treated as an aborted request, rather than an error
- Allow instantiating Comms outside of the IPython kernel
4.5.0
*****
`4.5 on GitHub <https://github.com/ipython/ipykernel/milestones/4.5>`__
- Use figure.dpi instead of savefig.dpi to set DPI for inline figures
- Support ipympl matplotlib backend (requires IPython update as well to fully work)
- Various bugfixes, including fixes for output coming from threads,
and :func:`input` when called with non-string prompts, which stdlib allows.
4.4
---
4.4.1
*****
`4.4.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.4.1>`__
- Fix circular import of matplotlib on Python 2 caused by the inline backend changes in 4.4.0.
4.4.0
*****
`4.4.0 on GitHub <https://github.com/ipython/ipykernel/milestones/4.4>`__
- Use `MPLBACKEND`_ environment variable to tell matplotlib >= 1.5 use use the inline backend by default.
This is only done if MPLBACKEND is not already set and no backend has been explicitly loaded,
so setting ``MPLBACKEND=Qt4Agg`` or calling ``%matplotlib notebook`` or ``matplotlib.use('Agg')``
will take precedence.
- Fixes for logging problems caused by 4.3,
where logging could go to the terminal instead of the notebook.
- Add ``--sys-prefix`` and ``--profile`` arguments to :command:`ipython kernel install`
- Allow Comm (Widget) messages to be sent from background threads.
- Select inline matplotlib backend by default if ``%matplotlib`` magic or
``matplotlib.use()`` are not called explicitly (for matplotlib >= 1.5).
- Fix some longstanding minor deviations from the message protocol
(missing status: ok in a few replies, connect_reply format).
- Remove calls to NoOpContext from IPython, deprecated in 5.0.

4.3
---
4.3.2
*****
- Use a nonempty dummy session key for inprocess kernels to avoid security
warnings.
4.3.1
*****
- Fix Windows Python 3.5 incompatibility caused by faulthandler patch in 4.3
4.3.0
*****
`4.3.0 on GitHub <https://github.com/ipython/ipykernel/milestones/4.3>`__
- Publish all IO in a thread, via :class:`IOPubThread`.
This solves the problem of requiring :meth:`sys.stdout.flush` to be called in the notebook to produce output promptly during long-running cells.
- Remove refrences to outdated IPython guiref in kernel banner.
- Patch faulthandler to use ``sys.__stderr__`` instead of forwarded ``sys.stderr``,
which has no fileno when forwarded.
- Deprecate some vestiges of the Big Split:
- :func:`ipykernel.find_connection_file` is deprecated. Use :func:`jupyter_client.find_connection_file` instead.
- Various pieces of code specific to IPython parallel are deprecated in ipykernel
and moved to ipyparallel.
4.2

4.2.2
*****
`4.2.2 on GitHub <https://github.com/ipython/ipykernel/milestones/4.2.2>`__
- Don't show interactive debugging info when kernel crashes
- Fix handling of numerical types in json_clean
- Testing fixes for output capturing
4.2.1
*****
`4.2.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.2.1>`__
- Fix default display name back to "Python X" instead of "pythonX"
4.2.0
*****
`4.2 on GitHub <https://github.com/ipython/ipykernel/milestones/4.2>`_
- Support sending a full message in initial opening of comms (metadata, buffers were not previously allowed)
- When using ``ipython kernel install --name`` to install the IPython kernelspec, default display-name to the same value as ``--name``.
4.1
---
4.1.1
*****
`4.1.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.1.1>`_
- Fix missing ``ipykernel.__version__`` on Python 2.
- Fix missing ``target_name`` when opening comms from the frontend.
4.1.0
*****
`4.1 on GitHub <https://github.com/ipython/ipykernel/milestones/4.1>`_
- add ``ipython kernel install`` entrypoint for installing the IPython
kernelspec
- provisional implementation of ``comm_info`` request/reply for msgspec
v5.1
4.0
---
`4.0 on GitHub <https://github.com/ipython/ipykernel/milestones/4.0>`_
4.0 is the first release of ipykernel as a standalone package.
