+The ``profiling.sampling`` flamegraph profiler now supports inverted
+flamegraph view that aggregates all leaf nodes. In a standard flamegraph, if
+a hot function is called from multiple locations, it appears multiple times
+as separate leaf nodes. In the inverted flamegraph, all occurrences of the
+same leaf function are merged into a single aggregated node at the root,
+showing the total hotness of that function in one place. The children of each
+aggregated node represent its callers, making it easier to identify which
+functions consume the most CPU time and where they are called from.
