just curious regarding Davids tweet the last few days... Now they they solved the latest bugs , do they now how to put it thru a beta test to make sure these changes in the past week or two are going to be good for the long term? I have no idea how the testing of a new product works, so what do others think in this? Are there weeks more of testing or could the upgraded software be installing any day now?
