• Issue #3112 : Change meta key UploadUser to UploadUserId. Add meta key UploadUserUsername to hold the preferred_username from the IDP. NOTE: the stroom property receive.requireTokenAuthentication and proxy property receivedDataConfig.requireTokenAuthentication have both been replaced by tokenAuthenticationEnabled, certificateAuthenticationEnabled and authenticationRequired, allowing authentication to be disabled and the mechanism to be controlled on data receipt. Remove properties receive.unknownClassification and receive.feedNamePattern as they are unused and duplicates of other properties. Replace property security.authentication.useInternal (boolean) with security.authentication.identityProviderType (INTERNAL|EXTERNAL|TEST). Add property addOpenIdAccessToken to the HTTP forward config. Remove property useDefaultOpenIdCredentials as this is now covered by security.authentication.identityProviderType. In proxy YAML config, replaced forwardDestinations with forwardFileDestinations and forwardHttpDestinations; replaced receiveDataConfig with receive.
