Doing a release =============== Doing a release of ``cryptography`` requires a few steps. Verifying and upgrading OpenSSL version --------------------------------------- The release process uses a static build for Windows and macOS wheels. Check that the Windows and macOS Jenkins builders have the latest version of OpenSSL installed before performing the release. If they do not: Upgrading Windows ~~~~~~~~~~~~~~~~~ Run the ``openssl-release-1.1`` Jenkins job, then copy the resulting artifacts to the Windows builders and unzip them in the root of the file system. Upgrading macOS ~~~~~~~~~~~~~~~ ``brew update`` and then ``brew upgrade openssl@1.1 --build-bottle`` to install a 64-bit only library compatible with all Intel Macs. Bumping the version number -------------------------- The next step in doing a release is bumping the version number in the software. * Update the version number in ``src/cryptography/__about__.py``. * Update the version number in ``vectors/cryptography_vectors/__about__.py``. * Set the release date in the :doc:`/changelog`. * Do a commit indicating this. * Send a pull request with this. * Wait for it to be merged. Performing the release ---------------------- The commit that merged the version number bump is now the official release commit for this release. You will need to have ``gpg`` installed and a ``gpg`` key in order to do a release. Once this has happened: * Run ``python release.py {version}``. The release should now be available on PyPI and a tag should be available in the repository. Verifying the release --------------------- You should verify that ``pip install cryptography`` works correctly: .. code-block:: pycon >>> import cryptography >>> cryptography.__version__ '...' >>> import cryptography_vectors >>> cryptography_vectors.__version__ '...' Verify that this is the version you just released. For the Windows wheels check the builds for the ``cryptography-wheel-builder`` job and verify that the final output for each build shows it loaded and linked the expected OpenSSL version. Post-release tasks ------------------ * Update the version number to the next major (e.g. ``0.5.dev1``) in ``cryptography/__about__.py`` and ``vectors/cryptography_vectors/__about__.py``. * Close the `milestone`_ for the previous release on GitHub. * Add new :doc:`/changelog` entry with next version and note that it is under active development * Send a pull request with these items * Check for any outstanding code undergoing a deprecation cycle by looking in ``cryptography.utils`` for ``DeprecatedIn**`` definitions. If any exist open a ticket to increment them for the next release. * Send an email to the `mailing list`_ and `python-announce`_ announcing the release. .. _`milestone`: https://github.com/pyca/cryptography/milestones .. _`mailing list`: https://mail.python.org/mailman/listinfo/cryptography-dev .. _`python-announce`: https://mail.python.org/mailman/listinfo/python-announce-list
