--- features: - | The following configuration variables, normally defined in ``conf.py``, can now be configured automatically. - ``project`` - ``version`` - ``release`` - ``html_last_updated_fmt`` - ``latex_engine`` - ``latex_elements`` It is not necessary to retain any configuration in ``conf.py`` and, in most cases, such configuration will be ignored. The sole exceptions to this rule are ``version`` and ``release`` which, if set to ``''`` will not be overridden. This allows for unversioned documentation.
