If either the prosecution or the defendant subsequently learns of
additional material or information which it would have been under a duty

shall expeditiously notify the other party and disclose the additional
material and information as required for initial discovery under this
article. This section also requires expeditious disclosure by the
prosecution of material or information that became relevant to the case
or discoverable based on reciprocal discovery received from the
