 Attribute Changes in Clang
 --------------------------
+- Introduced a new function attribute 
``__attribute__((amdgpu_max_num_work_groups(x, y, z)))`` or
+  ``[[clang::amdgpu_max_num_work_groups(x, y, z)]]`` for the AMDGPU target. 
This attribute can be
+  attached to HIP or OpenCL kernel function definitions to provide an 
optimization hint. The parameters
+  ``x``, ``y``, and ``z`` specify the maximum number of workgroups for the 
respective dimensions,
+  and each must be a positive integer.
