@@ -25,6 +25,7 @@ The following changes in version 1.24 affect C/C++ analysis in all applications.
 | No space for zero terminator (`cpp/no-space-for-terminator`) | Fewer false positive results | This query has been modified to be more conservative when identifying which pointers point to null-terminated strings.  This approach produces fewer, more accurate results. |
 | Overloaded assignment does not return 'this' (`cpp/assignment-does-not-return-this`) | Fewer false positive results | This query no longer reports incorrect results in template classes. |
 | Unsafe array for days of the year (`cpp/leap-year/unsafe-array-for-days-of-the-year`) |  | This query is no longer run on LGTM. |
+| Unsigned comparison to zero (`cpp/unsigned-comparison-zero`) | More correct results | This query now also looks for comparisons of the form `0 <= x`. |
