And more things which are not mentioned in the changelog:
How it detects build plate?
Ok, didn’t know that A1 has two cameras.
it dont have 
maybe its someting on the bambu studio
Let us know when is not beta! 
u can install the beta version if u want… just check the beta fw version on the app studio
Nope, not that. there is no camera that can see that code.
It drags the nozzle over the flexible part on the top end of the build plate and “looks” for the slot in the build plate. (That’s at least what I could observe)
I did not try that on the A1 mini yet.
That makes sense, “Build plate detection” as in seeing if a build plate is actually in place.
Exactly, the latest Bambu Studio release makes a better job with naming that feature:
- A series supports plate position detection function(The firmware needs to be upgraded to version 01.02.00.00.)
great another thing to damage the nozzle faster 
It should not do much, but if you don’t like the thought of it doing that, there is an option to disable it, (Its disabled by default)
Is this beta firmware also available for the A1 mini ?
Yeah, it’s available for the A1 and A1 mini.
That’s weired, I joined the beta program this morning, but the beta update won’t show, I tried to opt out and opt back in and rebooted the printer multiple times to no avail
I remember reading something about them enabling devices once a beta is available. I guess they will not do that right away, so it might take a while to allow your account for the beta. I don’t know the process since it’s the first real public beta over that app setting. It might be possible that you have to wait for a new build or even the next beta round.
Thats how it works, its is just a better idea to not deliver beta updates to everyone at the same time, because if something breaks critically, the amount of people affected is limited.
Impressive set of new features on this beta 
the QR code in the printer should point to the forum when it upgrades to beta tho
I switch back to the original firmware. Firmeware 01,01,50,24 and also 01.01.50.26 prints fine without anny issues, but i don’t see a live video while printing in Bambus Studio or Bambu Handy. Before and after the print, the live video works. After downgrade to the original firmeware, the video works also while prining.
whats does the timeslapes fade on mode?
