@@ -22,6 +22,7 @@ The following changes in version 1.24 affect C/C++ analysis in all applications.
 | No space for zero terminator (`cpp/no-space-for-terminator`) | More correct results | String arguments to formatting functions are now (usually) expected to be null terminated strings. |
 | Hard-coded Japanese era start date (`cpp/japanese-era/exact-era-date`) |  | This query is no longer run on LGTM. |
 | 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. |
+| Overflow in uncontrolled allocation size (`cpp/uncontrolled-allocation-size`) | Fewer false positive results | Cases where the tainted allocation size is range checked are now more reliably excluded. |
 | 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. |
