| Doing a release | 
 | =============== | 
 |  | 
 | Doing a release of ``cryptography`` is a two part process. | 
 |  | 
 | Bumping the version number | 
 | -------------------------- | 
 |  | 
 | The first step in doing a release is bumping the version number in the | 
 | software. | 
 |  | 
 | * Update the version number in ``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 ``invoke release {version}``. | 
 |  | 
 | The release should now be available on PyPI and a tag should be available in | 
 | the repository. 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. | 
 |  | 
 | 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``. | 
 | * 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. |
