@@ -319,3 +319,13 @@ Changes made since CMake 3.21.0 include the following.
 
 * The :generator:`Visual Studio 17 2022` generator is now based on
   "Visual Studio 2022 Preview 4".  Previously it was based on "Preview 3.1".
+
+* The AMD ROCm Platform ``hipcc`` compiler was identifed by CMake 3.21.0
+  through 3.21.2 as a distinct compiler with id ``ROCMClang``.  This has
+  been removed because it caused regressions.  Instead:
+
+  * ``hipcc`` may no longer be used as a ``HIP`` compiler because it
+    interferes with flags CMake needs to pass to Clang.  Use Clang directly.
+
+  * ``hipcc`` may once again be used as a ``CXX`` compiler, and is treated as
+    whatever compiler it selects underneath, as CMake 3.20 and below did.
