| **Query** | **Tags** | **Purpose** |
|-----------------------------|-----------|--------------------------------------------------------------------|
| Lossy function result cast (`cpp/lossy-function-result-cast`) | correctness | Finds function calls whose result type is a floating point type, which are implicitly cast to an integral type. Newly available but not displayed by default on LGTM. |
## Changes to existing queries
| **Query** | **Expected impact** | **Change** |
|----------------------------|------------------------|------------------------------------------------------------------|
| Suspicious pointer scaling (`cpp/suspicious-pointer-scaling`) | Fewer false positives | False positives involving types that are not uniquely named in the snapshot have been fixed. |
| Lossy function result cast (`cpp/lossy-function-result-cast`) | Fewer false positive results | The whitelist of rounding functions built into this query has been expanded. |
| Unused static variable (`cpp/unused-static-variable`) | Fewer false positive results | Variables with the attribute `unused` are now excluded from the query. |
| Resource not released in destructor (`cpp/resource-not-released-in-destructor`) | Fewer false positive results | Fix false positives where a resource is released via a virtual method call. |
