Release Procedure

On your build Pi, perform the following steps:

Ensure you have a reliable Internet connection (preferably Ethernet).
Ensure you have the following Debian packages installed: devscripts, dput, python-all, python3-all, gnupg, build-essential, git, python-setuptools, python3-setuptools, python-rpi.gpio, python3-rpi.gpio

Ensure you have a valid ~/.pypirc configuration. For example:

[distutils]
index-servers =
    pypi

[pypi]
username:my_username
password:my_long_password

Ensure you have a valid ~/.dput.cf setup which includes the [raspberrypi] target. For example:

[raspberrypi]
fqdn = build-master.raspberrypi.org
incoming = incoming
login = incoming
method = scp

Ensure you have a valid public/private key-pair defined for GNUPG.
In the python-gpiozero directory, run make release. This will launch dch to update the Debian changelog. Fill this out properly (ticket references!) and the release will be generated, tagged, signed, and registered with GitHub and PyPI.

Note

Although the release has been registered at this point, no packages have been generated or uploaded to any service.
Still in the python-gpiozero directory, run make upload. This will generate the actual debian packages, upload them to Raspbian, and upload the source package to PyPI.
On GitHub, close any milestone associated with the release.
On ReadTheDocs, update the project configuration to build the new release, then set it to the default version for the project.
