--- upgrade: - | The default value of ``[oslo_policy]policy_file`` config option has been changed from ``policy.json`` to ``policy.yaml``. Operators who are utilizing customized policy files or previously generated static policy files (which are not needed by default), should generate new policy files and modify them to meet their needs in the event of any new policies or rules have been added. Please consult the `oslopolicy-convert-json-to-yaml `_ tool to convert a JSON to YAML formatted policy file in backward compatible way. deprecations: - | Use of legacy policy format was deprecated by the ``oslo.policy`` library during the Victoria development cycle. As a result, this deprecation is being noted in the Wallaby with an anticipated future removal of support by ``oslo.policy``. As such operators will need to convert to YAML policy files. Please see the upgrade notes for details on migration of any custom policy files.
