A plain look at what changed, and what it means from here.
The rules are not new. What is new is how many people they now apply to.
The exceptions
The exceptions matter more than the rule, and there are three of them. There is a deadline involved, and missing it costs more than the difference.
What it costs
The practical effect is easier to see in a single example than in a summary. Most of the confusion comes from two terms that sound alike and mean different things.
None of this is urgent, but it is worth an hour before the next renewal.
