| **Query** | **Expected impact** | **Change** |
|----------------------------|------------------------|------------------------------------------------------------------|
| Expression has no effect (`cpp/useless-expression`) | Fewer false positive results | Calls to functions with the `weak` attribute are no longer considered to be side effect free, because they could be overridden with a different implementation at link time. |
| Suspicious pointer scaling (`cpp/suspicious-pointer-scaling`) | Lower precision | The precision of this query has been reduced to "medium". This coding pattern is used intentionally and safely in a number of real-world projects. Results are no longer displayed on LGTM unless you choose to display them. |
