CONTRIBUTING.md
#339
- Fix compatibility with IPython 7.0 #348
- Fix compatibility in cases where sys.stdout can be None #344

- set zmq.ROUTER_HANDOVER socket option when available to workaround libzmq reconnect bug #300.
- Fix sdists including absolute paths for kernelspec files, which prevented installation from sdist on Windows #306.
- Cleanly shutdown integrated event loops when shutting down the kernel. #290
%gui qt
now uses Qt 5 by default rather than Qt 4, following a similar change in terminal IPython. #293- Fix event loop integration for
asyncio
when run with Tornado 5, which uses asyncio where available. #296
- Add event loop integration for
asyncio
. - Use the new IPython completer API.

image/gif
). - Allow the kernel to be interrupted without killing the Qt console.

is_complete
response with cell magics. - Clean up encoding of bytes objects.

-
Add to API
DisplayPublisher.publish
two new fully backward-compatible keyword-args:update: bool
transient: dict
-
Support new
transient
key indisplay_data
messages spec forpublish
. For a display data message,transient
contains data that shouldn't be persisted to files or documents. Add adisplay_id
to thistransient
dict bydisplay(obj, display_id=\...)
-
Add
ipykernel_launcher
module which removes the current working directory fromsys.path
before launching the kernel. This helps to reduce the cases where the kernel won't start because there's arandom.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

OutStream
to inherit fromTextIOBase
instead of object to improve API support and error reporting -

-
Various bugfixes
- Fix bug when instantiating Comms outside of the IPython kernel (introduced in 4.5.1).
- Add missing
stream
parameter to overriddengetpass
- 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
- 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
input
when called with non-string prompts, which stdlib allows.
- Fix circular import of matplotlib on Python 2 caused by the inline backend changes in 4.4.0.
- 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
ormatplotlib.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 toipython kernel install
. - Allow Comm (Widget) messages to be sent from background threads.
- Select inline matplotlib backend by default if
%matplotlib
magic ormatplotlib.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.
- Use a nonempty dummy session key for inprocess kernels to avoid security warnings.
- Fix Windows Python 3.5 incompatibility caused by faulthandler patch in 4.3
-
Publish all IO in a thread, via
IOPubThread
. This solves the problem of requiringsys.stdout.flush
to be called in the notebook to produce output promptly during long-running cells. -
Remove references to outdated IPython guiref in kernel banner.
-
Patch faulthandler to use
sys.__stderr__
instead of forwardedsys.stderr
, which has no fileno when forwarded. -
Deprecate some vestiges of the Big Split:
ipykernel.find_connection_file
is deprecated. Usejupyter_client.find_connection_file
instead.
- Various pieces of code specific to IPython parallel are deprecated in ipykernel and moved to ipyparallel.
- Don't show interactive debugging info when kernel crashes
- Fix handling of numerical types in json_clean
- Testing fixes for output capturing
- Fix default display name back to "Python X" instead of "pythonX"
- 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
.
- Fix missing
ipykernel.__version__
on Python 2. - Fix missing
target_name
when opening comms from the frontend.
- add
ipython kernel install
entrypoint for installing the IPython kernelspec - provisional implementation of
comm_info
request/reply for msgspec v5.1
4.0 is the first release of ipykernel as a standalone package.
