-| Resource not released in destructor | Fewer false positive results | Placement new is now excluded from the query. |
+| Resource not released in destructor | Fewer false positive results | Placement new is now excluded from the query. Also fixed an issue where false positives could occur if the destructor body was not in the snapshot. |
 | Missing return statement (`cpp/missing-return`) | Visible by default | The precision of this query has been increased from 'medium' to 'high', which makes it visible by default in LGTM. It was 'medium' in release 1.17 and 1.18 because it had false positives due to an extractor bug that was fixed in 1.18. |
 | Call to memory access function may overflow buffer | More correct results | Array indexing with a negative index is now detected by this query. |
 | Suspicious add with sizeof | Fewer false positive results | Arithmetic with void pointers (where allowed) is now excluded from this query. |
