@@ -14,6 +14,9 @@ The following changes in version 1.26 affect C/C++ analysis in all applications.
| **Query** | **Expected impact** | **Change** |
|----------------------------|------------------------|------------------------------------------------------------------|
| 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. |
| Comparison result is always the same (`cpp/constant-comparison`) | More correct results | Bounds on expressions involving multiplication can now be determined in more cases. |
## Changes to libraries
* The `SimpleRangeAnalysis` library now supports multiplications of the form
`e1 * e2` when `e1` and `e2` are unsigned.
