strange IB hasn't updated the stand alone version beyond 918 even though version 920 is in production. never saw this before, and I would think it a trivial task, so maybe there's some other reason
There must have been a problem with 919. I think I will do my standard procedure of waiting a few days before doing an update to 920.
TWS 920 uses a different data streaming packaging method. It is a major revision, not something to be taken lightly.
