## 6.0.0

([Full Changelog](https://github.com/ipython/ipykernel/compare/aba2179420a3fa81ee6b8a13f928bf9e5ce50716...6d04ad2bdccd0dc0daf20f8d53555174b5fefc7b))

IPykernel 6.0 is the first major release in about two years, that brings a number of improvements, code cleanup, and new
features to IPython.

You should be able to view all closed issues and merged Pull Request for this
milestone [on
GitHub](https://github.com/ipython/ipykernel/issues?q=milestone%3A6.0+is%3Aclosed+),
as for any major releases, we advise greater care when updating that for minor
release and welcome any feedback (~50 Pull-requests).

IPykernel 6 should contain all changes of the 5.x series, in addition to the
following non-exhaustive changes.

- Support for the debugger protocol, when using `JupyterLab`, `RetroLab` or any
  frontend supporting the debugger protocol you should have access to the
  debugger functionalities.

- The control channel on IPykernel 6.0 is run in a separate thread, this may
  change the order in which messages are processed, though this change was necessary
  to accommodate the debugger.

- We now have a new dependency: `matplotlib-inline`, this helps to separate the
  circular dependency between IPython/IPykernel and matplotlib.

- On POSIX systems, all outputs to stdout/stderr should now be captured,
  including subprocesses and output of compiled libraries (blas, lapack....).
  In notebook server, some outputs that would previously go to the notebooks
  logs will now both head to notebook logs and in notebooks outputs. In
  terminal frontend like Jupyter Console, Emacs or other, this may ends up as
  duplicated outputs.

- coroutines are now native (async-def) , instead of using tornado's
  `@gen.coroutine`

- OutStreams can now be configured to report `istty() == True`, while this
  should make some output nicer (for example colored), it is likely to break
  others. Use with care.

### Deprecations in 6.0

- `Kernel`s now support only a single shell stream, multiple streams will now be ignored. The attribute
  `Kernel.shell_streams` (plural) is deprecated in ipykernel 6.0. Use `Kernel.shell_stream` (singular)
- `Kernel._parent_header` is deprecated, even though it was private. Use `.get_parent()` now.

### Removal in 6.0

- `ipykernel.codeutils` was deprecated since 4.x series (2016) and has been removed, please import similar
  functionalities from `ipyparallel`
- remove `find_connection_file` and `profile` argument of `connect_qtconsole` and `get_connection_info`, deprecated since IPykernel 4.2.2 (2016).

  available. [#296](https://github.com/ipython/ipykernel/pull/296)

## 4.7

### 4.7.0

[4.7.0 on GitHub](https://github.com/ipython/ipykernel/milestones/4.7)

- Add support for displaying GIF images (mimetype `image/gif`).
- Allow the kernel to be interrupted without killing the Qt console.
- Fix `is_complete` response with cell magics.
- Clean up encoding of bytes objects.
- Clean up help links to use `https` and improve display titles.
- Clean up ioloop handling in preparation for tornado 5.

## 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
  `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 `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](http://matplotlib.org/devel/coding_guide.html?highlight=mplbackend#developing-a-new-backend)
  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
  `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 `IOPubThread`. This solves the problem of requiring
  `sys.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 forwarded
  `sys.stderr`, which has no fileno when forwarded.

- Deprecate some vestiges of the Big Split:

  - `ipykernel.find_connection_file`
    is deprecated. Use
    `jupyter_client.find_connection_file` instead.

  \- Various pieces of code specific to IPython parallel are
  deprecated in ipykernel and moved to ipyparallel.
