| `()`-declared function called with too many arguments (`cpp/futile-params`) | Improved coverage | Query has been generalized to find all cases where the number of arguments exceedes the number of parameters of the function, provided the function is also properly declared/defined elsewhere. |
## Changes to QL libraries
- The predicate `Declaration.hasGlobalName` now only holds for declarations that are not nested in a class. For example, it no longer holds for a member function `MyClass::myFunction` or a constructor `MyClass::MyClass`, whereas previously it would classify those two declarations as global names.
- In class `Declaration`, predicates `getQualifiedName/0` and `hasQualifiedName/1` are no longer recommended for finding functions by name. Instead, use `hasGlobalName/1` and the new `hasQualifiedName/2` and `hasQualifiedName/3` predicates. This improves performance and makes it more reliable to identify names involving templates.
- Additional support for definition by reference has been added to the `semmle.code.cpp.dataflow.TaintTracking` library.
- The taint tracking library now includes taint-specific edges for functions modeled in `semmle.code.cpp.models.interfaces.DataFlow`.
- The taint tracking library adds flow through library functions that are modeled in `semmle.code.cpp.models.interfaces.Taint`. Queries can add subclasses of `TaintFunction` to specify additional flow.
