[Koha] Does Koha log when a circulation rule gets changed?

Gentle Reader, One of our libraries has discovered they have a "rogue" circulation rule and we are trying to establish how long this rule has been present. I know that Koha logs things like checkouts and checkins and patron modifications, but does it log when a change is made to the circulation rules? I can't see it in the log viewer tool.
