Note
This documentation is for a development version of IPython. There may be significant differences from the latest stable release.
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. IPython subprojects, such as IPython.parallel and widgets 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
IPython.utils.path
toIPython.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 PR #8480 an #8478. - The
--deep-reload
flag and the corresponding options to injectdreload
orreload
into the interactive namespace have been deprecated, and will be removed in future versions. You should now explicitly importreload
fromIPython.lib.deepreload
to use it.
