If 3eea8b5d68c801fec788b411582b803463834752's behaviour should become the new behaviour it should be documented, that maximum and fuzz values are dependent on each other. Instead I suggest to restore the old behaviour. -- Sebastian -------------- next part -------------- A non-text attachment was scrubbed...
