1. My guess is that the update was probably developed weeks ago but only released to the public recently.
2. As long as your flying between 30 centimetres and 3 meters (VPS range) you should notice in the lower right hand corner of pilot app /camera screen a small icon with green radio waves coming out. This will show your exact altitude indoors or out. this does not need testing.
3 Probably just a glitch. It might get fixed in the next firmware update next week.
3b. Gimbal Horizon issues mean that when you playback your video and the horizon looks tilted or not level. To repair do a gimbal calibration located in the app.
