No, the Comptroller hasn't released the 502LU.  We expect it on the 15th.  No, ProSeries hasn't updated since there is nothing to update as of today. When do we expect the update - somewhere between April 15th and October 15th.  Expecting two weeks or so after issuance +-. ProSeries has not updated Maryland software for the date as of yet.
