I do not think a change entry is needed for this. |

Unless we're absolutely certain that the float representation of every possible outcome is the same, I'd put it in a Changes entry... someone'll notice otherwise! 🙂 |

Well spotted! This is a nice improvement: even if we use the hypot emulation in runtime/floats.c, NaNs and infinities are handled better in Float.hypot than in the current code for Complex.norm. Plus, we reduce code size.
I agree with @dra27 that a Changes entry would be useful.

I know that OCaml is in feature freeze at the moment but I nonetheless submit this (trivial) PR before I forget!
