Qt is exemplary in that. There are ironclad rules that only MINOR adds new features and only MAJOR breaks API. And PATCH is strictly for bugfixes.
Binary compatibility is guaranteed as well so that an application compiled against 5.0.0 will dynamically link against 5.15.2 and run fine unless it relied on clear bugs.
There are exceptions for things like input method plugins, for which one needs to explicitly opt in to using internal API with build sysem flags. Without the opt-in, the corresponding private headers are not accessible.
