 ### Assembler, binary parser, and disassembler
 
-* Based on SPIR-V 1.0 Revision 3.
-  * Supports GLSL std450 extended instructions.
-  * Supports OpenCL extended instructions.
+* Based on SPIR-V version 1.1 Rev 1
+* Support for extended instruction sets:
+  * GLSL std450 version 1.0 Rev 3
+  * OpenCL version 1.0 Rev 2
+* Support for SPIR-V 1.0 (with or without additional restrictions from Vulkan 1.0)
 * Assembler only does basic syntax checking.  No cross validation of
   IDs or types is performed, except to check literal arguments to
   `OpConstant`, `OpSpecConstant`, and `OpSwitch`.
