+
+=======================
+IPython release process
+=======================
+
+This document contains the process that is used to create an IPython release.
+
+Conveniently, the ``release`` script in the ``tools`` directory of the ``IPython``
+repository automates most of the release process. This document serves as a
+handy reminder and checklist for the release manager.
+
+During the release process, you might need the extra following dependencies:
+
+ - ``keyring`` to access your GitHub authentication tokens
+ - ``graphviz`` to generate some graphs in the documentation
+
+Make sure you have all the required dependencies to run the tests as well.
+
+
+1. Set Environment variables
+----------------------------
+
+Set environment variables to document previous release tag, current
+release milestone, current release version, and git tag.
+
+These variables may be used later to copy/paste as answers to the script
+questions instead of typing the appropriate command when the time comes. These
+variables are not used by the scripts directly; therefore, there is no need to
+``export`` them. The format for bash is as follows, but note that these values
+are just an example valid only for the 5.0 release; you'll need to update them
+for the release you are actually making::
+
+    PREV_RELEASE=4.2.1
+    MILESTONE=5.0
+    VERSION=5.0.0
+    BRANCH=master
+
+
+2. Create GitHub stats and finish release note
+----------------------------------------------
+
+.. note::
+
+    This step is optional if making a Beta or RC release.
+
+.. note::
+
+    Before generating the GitHub stats, verify that all closed issues and pull
+    requests have `appropriate milestones
+    <https://github.com/ipython/ipython/wiki/Dev:-GitHub-workflow#milestones>`_.
+    `This search
+    <https://github.com/ipython/ipython/issues?q=is%3Aclosed+no%3Amilestone+is%3Aissue>`_
+    should return no results before creating the GitHub stats.
+
+If a major release:
+
+    - merge any pull request notes into what's new::
+
+          python tools/update_whatsnew.py
+
+    - update ``docs/source/whatsnew/development.rst``, to ensure it covers
+      the major release features
+
+    - move the contents of ``development.rst`` to ``versionX.rst`` where ``X`` is
+      the numerical release version
+
+    - generate summary of GitHub contributions, which can be done with::
+
+          python tools/github_stats.py --milestone $MILESTONE > stats.rst
+
+      which may need some manual cleanup of ``stats.rst``. Add the cleaned
+      ``stats.rst`` results to ``docs/source/whatsnew/github-stats-X.rst``
+      where ``X`` is the numerical release version (don't forget to add it to
+      the git repo as well). If creating a major release, make a new
+      ``github-stats-X.rst`` file; if creating a minor release, the content
+      from ``stats.rst`` may simply be added to the top of an existing
+      ``github-stats-X.rst`` file.  Finally, edit
+      ``docs/source/whatsnew/index.rst`` to list the new ``github-stats-X``
+      file you just created and remove temporarily the first entry called
+      ``development`` (you'll need to add it back after release).
+
+      Make sure that the stats file has a header or it won't be rendered in
+      the final documentation.
+
+To find duplicates and update `.mailmap`, use::
+
+    git log --format="%aN <%aE>" $PREV_RELEASE... | sort -u -f
+
+If a minor release you might need to do some of the above points manually, and
+forward port the changes.
+
+3. Make sure the repository is clean
+------------------------------------
+
+of any file that could be problematic.
+   Remove all non-tracked files with:
+
+   .. code::
+
+       git clean -xfdi
+
+   This will ask for confirmation before removing all untracked files. Make
+   sure the ``dist/`` folder is clean to avoid any stale builds from
+   previous build attempts.
+
+
+4. Update the release version number
+------------------------------------
+
+Edit ``IPython/core/release.py`` to have the current version.
+
+in particular, update version number and ``_version_extra`` content in
+``IPython/core/release.py``.
+
+Step 5 will validate your changes automatically, but you might still want to
+make sure the version number matches pep440.
+
+In particular, ``rc`` and ``beta`` are not separated by ``.`` or the ``sdist``
+and ``bdist`` will appear as different releases. For example, a valid version
+number for a release candidate (rc) release is: ``1.3rc1``. Notice that there
+is no separator between the '3' and the 'r'. Check the environment variable
+``$VERSION`` as well.
+
+You will likely just have to modify/comment/uncomment one of the lines setting
+``_version_extra``
+
+
+5. Run the `tools/build_release` script
+---------------------------------------
+
+Running ``tools/build_release`` does all the file checking and building that
+the real release script will do. This makes test installations, checks that
+the build procedure runs OK, and tests other steps in the release process.
+
+The ``build_release`` script will in particular verify that the version number
+match PEP 440, in order to avoid surprise at the time of build upload.
+
+We encourage creating a test build of the docs as well.
+
+6. Create and push the new tag
+------------------------------
+
+Commit the changes to release.py::
+
+    git commit -am "release $VERSION"
+    git push origin $BRANCH
+
+Create and push the tag::
+
+    git tag -am "release $VERSION" "$VERSION"
+    git push origin --tags
+
+Update release.py back to ``x.y-dev`` or ``x.y-maint``, and re-add the
+``development`` entry in ``docs/source/whatsnew/index.rst`` and push::
+
+    git commit -am "back to development"
+    git push origin $BRANCH
+
+Now checkout the tag we just made::
+
+    git checkout $VERSION
+
+7. Run the release script
+-------------------------
+
+Run the ``release`` script, this step requires having a current wheel, Python
+>=3.4 and Python 2.7.::
+
+    ./tools/release
+
+This makes the tarballs and wheels, and puts them under the ``dist/``
+folder. Be sure to test the ``wheels``  and the ``sdist`` locally before
+uploading them to PyPI. We do not use an universal wheel as each wheel
+installs an ``ipython2`` or ``ipython3`` script, depending on the version of
+Python it is built for. Using an universal wheel would prevent this.
+
+Use the following to actually upload the result of the build::
+
+    ./tools/release upload
+
+It should posts them to ``archive.ipython.org`` and to PyPI.
+
+PyPI/Warehouse will automatically hide previous releases. If you are uploading
+a non-stable version, make sure to log-in to PyPI and un-hide previous version.
+
+
+8. Draft a short release announcement
+-------------------------------------
+
+The announcement should include:
+
+- release highlights
+- a link to the html version of the *What's new* section of the documentation
+- a link to upgrade or installation tips (if necessary)
+
+Post the announcement to the mailing list and or blog, and link from Twitter.
+
+.. note::
+
+    If you are doing a RC or Beta, you can likely skip the next steps.
+
+9. Update milestones on GitHub
+-------------------------------
+
+These steps will bring milestones up to date:
+
+- close the just released milestone
+- open a new milestone for the next release (x, y+1), if the milestone doesn't
+  exist already
+
+10. Update the IPython website
+------------------------------
+
+The IPython website should document the new release:
+
+- add release announcement (news, announcements)
+- update current version and download links
+- update links on the documentation page (especially if a major release)
+
+11. Update readthedocs
+----------------------
+
+Make sure to update readthedocs and set the latest tag as stable, as well as
+checking that previous release is still building under its own tag.
+
+12. Update the Conda-Forge feedstock
+------------------------------------
+
+Follow the instructions on `the repository <https://github.com/conda-forge/ipython-feedstock>`_
+
+13. Celebrate!
+--------------
+
+Celebrate the release and please thank the contributors for their work. Great
+job!
