+
+=== Description
+
+This extension adds support for building programs written using the C++ for
+OpenCL kernel language documented in the *OpenCL-Docs* repository
+(https://github.com/KhronosGroup/OpenCL-Docs)
+with stable versions published in releases of the repository.
+
+This extension also enables applications to query the version of the language
+supported by the device compiler.
+
+=== New Enums
+
+  * {cl_device_info_TYPE}
+  ** {CL_DEVICE_CXX_FOR_OPENCL_NUMERIC_VERSION_EXT}
+
+=== New build option
+
+This extension adds support for a new `CLC++` value to be passed to the
+`-cl-std` build option accepted by {clBuildProgram} and {clCompileProgram}.
+
+=== Preprocessor Macros
+
+This extension defines a new language, instead of extending an existing
+language. As such, there will be no preprocessor `#define` matching the
+extension name string. Instead, dedicated preprocessor macros conveying
+language version information are available as described in the C++ for
+OpenCL Programming Language Documentation, section 2.2.2.2 "Predefined
+macros".
+
+=== Conformance tests
+
+. Test that a program can successfully be compiled with `-cl-std=CLC++`.
+. Test with a program compiled with `-cl-std=CLC++` that the value of the
+  +__OPENCL_CPP_VERSION__+ macro agrees with the version returned by
+  `CL_DEVICE_CXX_FOR_OPENCL_NUMERIC_VERSION_EXT`.
+
+=== Version History
+
+  * Revision 1.0.0, 2020-08-24
