### 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`.
