Elementary Question

[rotationslim]

I run a Church BB league. We play (to the extent possible)high school rules (volunteer refs).

We have an organizational meeting on Thursday.

My question is this:
Have there been any major changes in the HS rules? I am talking something like the change last year where 2 fewer players line up for FT.

I am not looking for, although important to this group, minor interpetations of rules, as we are a hack league and it would be pearls before swine.

I am just looking for any major changes. I have been through posts checking, but see nothing, I just want to know if I missed anything.
