WARNING

The official description of the development process is in the project's wiki and shouldn't be repeated here. Even the buzzwords mentioned here are most likely wrong.

CI is always used, but not CD, because deployment isn't our responsibility. - We're delivering open source software to anyone, so how should we be able to deploy it?

I doubt that the development practice is predominantly test-driven. That doesn't pair well the system integration tasks we're dealing with most of the time.
