We will update the rules on GitHub soon.
Regarding the annular ring, there’s no difference for KiCad between the Via annular ring and PTH annular ring. So you can only enter one value and may need to use a custom rule.
We chose 0.3mm as the new value as we enlarged PTH drills as described here: Plated and Non-Plated Holes if a too small is chosen initially, the end annular ring is not large enough for good solderability.
@anon6029747 Can you link us the footprint you mean?
