I haven't seen anything official although I wouldn't contemplate downloading a Beta onto my daily driver.
There are a few existing threads on the forum discussing Beta which may hold some relevant information.
Site's such as xdadevelopers.com and sammobile may have some more info on them too.
Daily Driver > Samsung Galaxy s²⁴ Ultra 512Gb ~ Titanium Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
