Not that I have a particular opinion on one way or another, but having the hash changing the value between releases could be a breaking change, if someone is using it e.g. in a memory mapped file.

Sure. As far as I can see, however, boost::hash has never promised hash stability, and the hash values have already changed a number of times.
