+- Improved OpenCL extension handling per target.
+- Added clang extension for function pointers ``__cl_clang_function_pointers``
+  and variadic functions ``__cl_clang_variadic_functions``, more details can be
+  found in :doc:`LanguageExtensions`.

+- Allow nested pointers (e.g. pointer-to-pointer) kernel arguments beyond OpenCL
+  1.2.
+- Added ``global_device`` and ``global_host`` address spaces for USM
+  allocations.
+
+Miscellaneous improvements in C++ for OpenCL support:
+
+- Added diagnostics for pointers to member functions and references to
