I agree that the version number does not give you a guarantee, that the software is without bugs. However, it does work the other way around: if the major version was bumped then you know something has broken and you will have to modify your code. If it was a bug fix release and something breaks, it is on them, not on you (as in, rollback your dependency upgrade and complain on their bug tracker). That is, if you did not rely on buggy behavior in the first place. As a side effect, if you really try to follow SemVer it will force you to think ahead a bit more because the fact that you broke the API is reflected in something quite obvious, rather than buried in a change log somewhere.
