*   Parameterless `tf.function`s are assumed to have an empty `input_signature` instead of an undefined one even if the `input_signature` is unspecified.
    *   `tf.types.experimental.TraceType` now requires an additional `placeholder_value` method to be defined.
    *   `tf.function` now traces with placeholder values generated by TraceType instead of the value itself.

  - a `lastTransitionTime` field was added
  - a `Failed` condition type was added to allow signers to indicate permanent failure; this condition can be added via the `certificatesigningrequests/status` subresource.
  - `Approved` and `Denied` conditions are mutually exclusive
