So they're following their usual pattern to come up with a new design before finishing the previous one. Efforts pulverization, as usual.
As for Ultra Station, the old version is not digitally signed, similar to the new one. So the OS still pop-ups a dialog that warns that the app is from unknown vendor. The integration with Ultra Sigma is broken. The new version is claimed to be backward compatible with the previous DG models. However, the waveform data text files (*.csv and *.txt) the app does create are now of different format, which seems to be one for all supported DG models. I wonder if that format can be really understood by the old models.
