--- features: - The KeystoneFernetKeys parameter was introduced, which is able to take any amount of keys as long as it's in the right format. It's generated by the same mechanism as the rest of the passwords; so it's value is also available via mistral's "password" environment variable. This will also allow for rotations to be made via mistral and via stack updates. deprecations: - The individual keystone fernet key parameters (KeystoneFernetKey0 and KeystoneFernetKey1) were deprecated in favor of KeystoneFernetKeys.
