How these are classified
Breaking means the vendor's own notes say so in plain language, or the package crossed a major version. Material means a deprecation, a security fix, or a migration note. A routine minor bump is neither, because flagging every release is how people learn to ignore alerts.
We do not claim to know about a change before it ships. What we do is read the release the moment it is published and tell you whether it matters.
