I think the devs (God Bless 'Em All) are still working out what's needed, what's desirable, and what works in terms of all the "issues".
"Almost certainly" based on past releases but that is just my opinion and means next to nothing in this case.
I feel pretty certain there aren't that many issues, that is just my feeling.
Perhaps the devs want more people to report issues to check first. That's just a possibility (but it would help make a better release).
Even if they have identified specific issues, that doesn't mean they have tested, solid solutions for them yet.i
I have no idea whatsoever of what any specific issue is.
