| 4.x Series | ||||
| ============ | ||||
| IPython 4.0 | ||||
| =========== | ||||
| Released August, 2015 | ||||
| IPython 4.0 is the first major release after the Big Split. | ||||
| IPython no longer contains the notebook, qtconsole, etc. which have moved to | ||||
| `jupyter <https://jupyter.readthedocs.org>`_. | ||||
| IPython subprojects, such as `IPython.parallel <https://ipyparallel.readthedocs.org>`_ and `widgets <https://ipywidgets.readthedocs.org>`_ have moved to their own repos as well. | ||||
| The following subpackages are deprecated: | ||||
| - IPython.kernel (now jupyter_client and ipykernel) | ||||
| - IPython.consoleapp (now jupyter_client.consoleapp) | ||||
| - IPython.nbformat (now nbformat) | ||||
| - IPython.nbconvert (now nbconvert) | ||||
| - IPython.html (now notebook) | ||||
| - IPython.parallel (now ipyparallel) | ||||
| - IPython.utils.traitlets (now traitlets) | ||||
| - IPython.config (now traitlets.config) | ||||
| - IPython.qt (now qtconsole) | ||||
| - IPython.terminal.console (now jupyter_console) | ||||
| and a few other utilities. | ||||
| Shims for the deprecated subpackages have been added, | ||||
| so existing code should continue to work with a warning about the new home. | ||||
| There are few changes to the code beyond the reorganization and some bugfixes. | ||||
| IPython highlights: | ||||
| - Public APIs for discovering IPython paths is moved from :mod:`IPython.utils.path` to :mod:`IPython.paths`. | ||||
| The old function locations continue to work with deprecation warnings. | ||||
| - Code raising ``DeprecationWarning`` | ||||
| entered by the user in an interactive session will now display the warning by | ||||
| default. See :ghpull:`8480` an :ghissue:`8478`. | ||||
| - The `--deep-reload` flag and the corresponding options to inject `dreload` or | ||||
| `reload` into the interactive namespace have been deprecated, and will be | ||||
| removed in future versions. You should now explicitly import `reload` from | ||||
| `IPython.lib.deepreload` to use it. | ||||
