============ 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 :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.
