--- upgrade: - | The `autogenerate_config_docs` set of tools has been removed. These were always buggy and hard to maintain, and they have been superseded by the ``oslo_config.sphinxext`` `Sphinx extension`__. __ https://docs.openstack.org/oslo.config/latest/reference/sphinxext.html - | The ``openstack-auto-commands`` command and its helper script in ``bin/doc-tools-update-cli-reference`` have been removed. These have been superseded by the ``cliff.sphinxext`` `Sphinx extensions`__. __ https://docs.openstack.org/cliff/latest/user/sphinxext.html - | The following scripts and tools have been removed: - prettify.py$ - remove_trailing_whitespaces.sh$ - remove_unnecessary_spaces.py$ - retf$ These were all indented to cleanup docs once they were already in tree, but our tooling and review process should be sufficient to catch most issues and there's limited value in submitting whitespace-fixup patches.
