No published changelog anywhere as well as no multi floor support.
And i you might ask, also no secondary map e.g. for mapping only (and avoid carpet areas etc.).
But its working pretty good for me tho.
I am looking forward for a easy to follow and mainly a nice and easiely/comfortable way of using it with Home Assistant.
So far all solutions I found here did somehow work at some degree but didnt gave me a comforable way of using it manually.
Best way is a little bit of this here, a little bit of entity buttons and a little bit of Xiaomi Vacuum Interactive Map Card.
But its still not perfect (and consumed lots of hours on making it even work).
So hopefullly this new firmware/feature will give this implementaion a boost and make it easier yet increase the usability.
