One of the last interactions I had with Captain Sim was with regard to the TCAS on the 777.  On about February 27, 2016 a revision was issued: "The TCAS problem has been fixed, and repacked in an updated installer. Use the Extended Download Service and download the 777-200 Base Pack".  So I know they are still issuing updates at least.  Patiently waiting for the release of their next aircraft.
