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.
|
|
