+| Declaration hides parameter (`cpp/declaration-hides-parameter`) | Fewer false positive results | False positives involving template functions have been fixed. |
 | Inconsistent direction of for loop (`cpp/inconsistent-loop-direction`) | Fewer false positive results | The query now accounts for intentional wrapping of an unsigned loop counter. |
 | Overflow in uncontrolled allocation size (`cpp/uncontrolled-allocation-size`) | | The precision of this query has been decreased from "high" to "medium". As a result, the query is still run but results are no longer displayed on LGTM by default. |
 | Comparison result is always the same (`cpp/constant-comparison`) | More correct results | Bounds on expressions involving multiplication can now be determined in more cases. |
