Instead of failing when --hatch-rate is used there should be a deprecation warning and the fail should not happen until release 2.0.

index.html still says hatch

[cyberw]

I dont really see a big benefit of deprecating things for any significant amount of time, so I couldnt really be bothered. Maybe I should make the next release be called 2.0 though, just to be clear that it contains breaking changes.

Good catch on index.html, fixing that now.

[cyberw]

Meh. But you are right. I will deprecate it for a while instead.
