(Full Changelog)

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,
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.

• 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.
