 - The SDK now uses logr as the default logger to unify the logging output with the controller-runtime logs. Users can still use a logger of their own choice. See the [logging doc](https://github.com/operator-framework/operator-sdk/blob/master/doc/user/logging.md) on how the SDK initializes and uses logr.
 - Ansible Operator CR status better aligns with [conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#typical-status-properties). ([#639](https://github.com/operator-framework/operator-sdk/pull/639))
-- The SDK now generates the CRD with the status subresource enabled by default. See the [client doc](https://github.com/operator-framework/operator-sdk/blob/masster/doc/user/client.md#updating-status-subresource) on how to update the status ssubresource.
