So long as no specifics are given (no fund name or similar), generic advertisements do not need to be filed with FINRA.

For purposes of lending and borrowing, “immediate family” now includes persons not directly related to the person but are still gettings some financial support, be it directly or indirectly from that person.

The Treble Damages (3x money illegally gained or loss illegally prevented or $1,000,000) is now $1,000,000 indexed for inflation.

The Gift Tax limit has been raised $1,000 from $14,000 to $15,000. That means 529s can have a max contribution of $15,000/year/person. A couple could contribute $30,000 per year per student. With the 5-year acceleration that is a single person able to gift away $75,000, and a couple $150,000.
