Changing the return type of a heavily used function is a completely different matter. It will break for anyone using is_float or expecting the float in some other way. I realise that there is an implicit conversion so it's not such a huge problem most of the time but there might be case where it is an issue. I don't see it as a bug fix in any way. It's more just an implication of the return type being a float. I think we should always weight the implication of the break. The way that I see it that some small breaks are acceptable for minor version but bigger breaks should be done only in major version. I would consider this (and anything changing a return types) as a bigger break. Cheers Jakub
