We appear to have lost the ability to step the EAF by Fine and Coarse steps with arrow keys in the v2.0.0 Beta (Build 30, firmware 10.08), even though the Fine and Coarse step fields are still there in the EAF setting window. Go figure -- there is no UI I can find that uses those fields anymore.
The only focuser icon in the main ASIAIR window leads directly to the autofocus window.
The only way to manually focus is to type in the EAF steps and tap GoTo.
Crosshair, annotation and star size tools are a direct tap now, instead of going through a parent menu.
There must have been so many complains of tracking stopping by itself that there is now a tracking indicator on the main window. There is a bug, though -- I am connected to the same ASIAIR from two different iPads, and one of them is showing that tracking is turned on (green) while the second iPad shows that tracking is stopped (red).
It also no longer waste screen real estate on the slew rate slider -- the slew slider only appears when you tap on the rate button. It is also harder now to inadvertently change the slewrate.
Nope, still no ROI choice for main camera, except for the ASI6200.
Guide camera now supports dark frames. Dark frame for guiding is automatically built by ASIAIR. (It may be building a library to cover from 0.5 second exposures to 5 second exposures. English is unfortunately my third language, and I don't quite understand what the instruction says exactly.) I had earlier tested my guide scope against light leaks when it is capped, so I think I am good to go to give it a shot later tonight.
Guide window now shows the gain of the guide camera, so the GUI is now more consistent with the main window. Now, if only they let us tap on that gain text to access a gain slider -- quite often, you'd like to change the gain of the guide camera while looking at the peak ADU of a guide star (changes when you slew to different parts of the sky).
Good news for those using a 12.9" iPad pro -- the GUI elements (icons and text) are no longer scaled up; the physical size of buttons etc are mostly constant between a 12.9" and a 9.7" iPad. "Bin1" no longer appears as a ginormous icon.
Another good news: they finally shrunk the icon to access the planetarium. There is now more room to manually stretch the white and dark points on the histogram curve.
