The API is not changing quickly any more. In fact, in most areas (if you're just dealing with documented features and not diving into obscure internals) it's as stable as it's going to get.

The most recent breaking change that I'm aware of was announced almost a year in advance (though it still caused some hardship). We really are trying to avoid doing that sort of thing if at all possible.

Yes, it's young and there will be bugs, but updates that "break all the nodes" should be a thing of the past.
