This document explains how to release Django.
Please, keep these instructions up-to-date if you make changes! The point here is to be descriptive, not prescriptive, so feel free to streamline or otherwise make changes, but update this document accordingly!
There are three types of releases that you might need to make:
The short version of the steps involved is:
There are a lot of details, so please read on.
You’ll need a few things before getting started:
A GPG key. If the key you want to use is not your default signing key, you’ll need to add -u firstname.lastname@example.org to every GPG signing command below, where email@example.com is the email address associated with the key you want to use.
An install of some required Python packages:
$ pip install wheel twine
Access to Django’s record on PyPI. Create a file with your credentials:
[pypi] username:YourUsername password:YourPassword
Access to the djangoproject.com server to upload files.
Access to the admin on djangoproject.com as a “Site maintainer”.
Access to post to django-announce.
If this is a security release, access to the pre-notification distribution list.
If this is your first release, you’ll need to coordinate with James and/or Jacob to get all these things lined up.
A few items need to be taken care of before even beginning the release process. This stuff starts about a week before the release; most of it can be done any time leading up to the actual release:
If this is a security release, send out pre-notification one week before the release. We maintain a list of who gets these pre-notification emails in the private django-core repository. Send the mail to firstname.lastname@example.org and BCC the pre-notification recipients. This email should be signed by the key you’ll use for the release, and should include patches for each issue being fixed.
As the release approaches, watch Trac to make sure no release blockers are left for the upcoming release.
Check with the other committers to make sure they don’t have any uncommitted changes for the release.
Proofread the release notes, including looking at the online version to catch any broken links or reST errors, and make sure the release notes contain the correct date.
Double-check that the release notes mention deprecation timelines for any APIs noted as deprecated, and that they mention any changes in Python version support.
Double-check that the release notes index has a link to the notes for the new release; this will be in docs/releases/index.txt.
If this is a feature release, ensure translations from Transifex have been integrated. This is typically done by a separate translation’s manager rather than the releaser, but here are the steps. Provided you have an account on Transifex:
$ python scripts/manage_translations.py fetch
and then commit the changed/added files (both .po and .mo). Sometimes there are validation errors which need to be debugged, so avoid doing this task immediately before a release is needed.
$ cd docs $ make man $ man _build/man/django-admin.1 # do a quick sanity check $ cp _build/man/django-admin.1 man/django-admin.1
and then commit the changed man page.
Write the announcement blog post for the release. You can enter it into the admin at any time and mark it as inactive. Here are a few examples: example security release announcement, example regular release announcement, example pre-release announcement.
OK, this is the fun part, where we actually push out a release!
Check Jenkins is green for the version(s) you’re putting out. You probably shouldn’t issue a release until it’s green.
A release always begins from a release branch, so you should make sure you’re on a stable branch and up-to-date. For example:
$ git checkout stable/1.5.x $ git pull
If this is a security release, merge the appropriate patches from django-private. Rebase these patches as necessary to make each one a simple commit on the release branch rather than a merge commit. To ensure this, merge them with the --ff-only flag; for example:
$ git checkout stable/1.5.x $ git merge --ff-only security/1.5.x
(This assumes security/1.5.x is a branch in the django-private repo containing the necessary security patches for the next release in the 1.5 series.)
If git refuses to merge with --ff-only, switch to the security-patch branch and rebase it on the branch you are about to merge it into (git checkout security/1.5.x; git rebase stable/1.5.x) and then switch back and do the merge. Make sure the commit message for each security fix explains that the commit is a security fix and that an announcement will follow (example security commit).
For a feature release, remove the UNDER DEVELOPMENT header at the top of the release notes and add the release date on the next line. For a patch release, replace *Under Development* with the release date. Make this change on all branches where the release notes for a particular version are located.
Update the version number in django/__init__.py for the release. Please see notes on setting the VERSION tuple below for details on VERSION.
In 1.4, the version number in docs/conf.py and setup.py should also be updated. Here’s an example commit updating version numbers for that.
If this is a pre-release package, update the “Development Status” trove classifier in setup.py to reflect this. Otherwise, make sure the classifier is set to Development Status :: 5 - Production/Stable.
Tag the release using git tag. For example:
$ git tag --sign --message="Tag 1.5.1" 1.5.1
You can check your work by running git tag --verify <tag>.
Push your work, including the tag: git push --tags.
Make sure you have an absolutely clean tree by running git clean -dfx.
Run make -f extras/Makefile to generate the release packages. This will create the release packages in a dist/ directory. Note that we don’t publish wheel files for 1.4.
Generate the hashes of the release packages:
$ cd dist $ md5sum * $ sha1sum * $ sha256sum *
Create a “checksums” file, Django-<<VERSION>>.checksum.txt containing the hashes and release information. Start with this template and insert the correct version, date, GPG key ID (from gpg --list-keys --keyid-format LONG), release URL, and checksums:
This file contains MD5, SHA1, and SHA256 checksums for the source-code tarball of Django <<VERSION>>, released <<DATE>>. To use this file, you will need a working install of PGP or other compatible public-key encryption software. You will also need to have the Django release manager's public key in your keyring; this key has the ID ``XXXXXXXXXXXXXXXX`` and can be imported from the MIT keyserver. For example, if using the open-source GNU Privacy Guard implementation of PGP: gpg --keyserver pgp.mit.edu --recv-key XXXXXXXXXXXXXXXX Once the key is imported, verify this file:: gpg --verify <<THIS FILENAME>> Once you have verified this file, you can use normal MD5, SHA1, or SHA256 checksumming applications to generate the checksums of the Django package and compare them to the checksums listed below. Release packages: ================= Django <<VERSION>> (tar.tgz): https://www.djangoproject.com/m/releases/<<RELEASE TAR.GZ FILENAME>> Django <<VERSION>> (.whl): https://www.djangoproject.com/m/releases/<<RELEASE WHL FILENAME>> MD5 checksums: ============== <<MD5SUM>> <<RELEASE TAR.GZ FILENAME>> <<MD5SUM>> <<RELEASE WHL FILENAME>> SHA1 checksums: =============== <<SHA1SUM>> <<RELEASE TAR.GZ FILENAME>> <<SHA1SUM>> <<RELEASE WHL FILENAME>> SHA256 checksums: ================= <<SHA256SUM>> <<RELEASE TAR.GZ FILENAME>> <<SHA256SUM>> <<RELEASE WHL FILENAME>>
Sign the checksum file (gpg --clearsign --digest-algo SHA256 Django-<version>.checksum.txt). This generates a signed document, Django-<version>.checksum.txt.asc which you can then verify using gpg --verify Django-<version>.checksum.txt.asc.
If you’re issuing multiple releases, repeat these steps for each release.
Now you’re ready to actually put the release out there. To do this:
Upload the release package(s) to the djangoproject server, replacing A.B. with the appropriate version number, e.g. 1.5 for a 1.5.x release:
$ scp Django-* djangoproject.com:/home/www/www/media/releases/A.B
Upload the checksum file(s):
$ scp Django-A.B.C.checksum.txt.asc djangoproject.com:/home/www/www/media/pgp/Django-A.B.C.checksum.txt
Test that the release packages install correctly using easy_install and pip. Here’s one method (which requires virtualenvwrapper):
$ RELEASE_VERSION='1.7.2' $ MAJOR_VERSION=`echo $RELEASE_VERSION| cut -c 1-3` $ mktmpenv $ easy_install https://www.djangoproject.com/m/releases/$MAJOR_VERSION/Django-$RELEASE_VERSION.tar.gz $ deactivate $ mktmpenv $ pip install https://www.djangoproject.com/m/releases/$MAJOR_VERSION/Django-$RELEASE_VERSION.tar.gz $ deactivate $ mktmpenv $ pip install https://www.djangoproject.com/m/releases/$MAJOR_VERSION/Django-$RELEASE_VERSION-py2.py3-none-any.whl $ deactivate
This just tests that the tarballs are available (i.e. redirects are up) and that they install correctly, but it’ll catch silly mistakes.
Ask a few people on IRC to verify the checksums by visiting the checksums file (e.g. https://www.djangoproject.com/m/pgp/Django-1.5b1.checksum.txt) and following the instructions in it. For bonus points, they can also unpack the downloaded release tarball and verify that its contents appear to be correct (proper version numbers, no stray .pyc or other undesirable files).
Upload the release packages to PyPI (for pre-releases, only upload the wheel file):
$ twine upload -s dist/*
Go to the Add release page in the admin, enter the new release number exactly as it appears in the name of the tarball (Django-<version>.tar.gz). So for example enter “1.5.1” or “1.4c2”, etc. If the release is part of an LTS branch, mark it so.
Make the blog post announcing the release live.
For a new version release (e.g. 1.5, 1.6), update the default stable version of the docs by flipping the is_default flag to True on the appropriate DocumentRelease object in the docs.djangoproject.com database (this will automatically flip it to False for all others); you can do this using the site’s admin.
Post the release announcement to the django-announce, django-developers, and django-users mailing lists. This should include a link to the announcement blog post. If this is a security release, also include email@example.com.
You’re almost done! All that’s left to do now is:
There are several items to do in the time following a the creation of a new stable branch (often following an alpha release). Some of these tasks don’t need to be done by the releaser.
Django’s version reporting is controlled by the VERSION tuple in django/__init__.py. This is a five-element tuple, whose elements are:
For a final release, the status is always “final” and the series number is always 0. A series number of 0 with an “alpha” status will be reported as “pre-alpha”.
