__declspec is not a core Clang language extension. Instead, require -fms-extensions or -fborland to enable the language extension.

Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets.

 Major New Features
 ------------------
 
-- Feature ...
+- Use of the ``__declspec`` language extension for declaration attributes now
+requires passing the -fms-extensions or -fborland compiler flag. This language
+extension is also enabled when compiling CUDA code, but its use should be
+viewed as an implementation detail that is subject to change.
