Note that you can disable this feature, however in most cases it's probably best not to -- the new hasher functionality is actually really cool and a good improvement on the old behavior. If you want to disable it, I think it's a compiler flag.

I believe the compiler flag just disables the random seed - you can still use the new hasher API
