Has the run rule in softball changed?

Booneville was ahead of Danville 15-0 after three today, and both teams seemed to be waiting for the umps to call the game for run-rule.  But they never did. 

I heard something later that it was changed to 12 after four and 10 after five, with no 3-inning run rule.  Is this true?

It's not a NFHS rule, but a state adoption that technically doesn't kick in until conference play. At that point, it's only 15 after 3 and 10 after 5. Conferences or teams can use the 15/3, 12/4, 10/5. It is something that is usually discussed at the plate meeting. If the coaches agree to 4 or more innings, they continue to play.

That's probably what happened.  Thanks!
