-* Very long instructions are supported, up to SPIR-V universal limits.
-* 32 and 64-bit floating point literals are encoded properly.
-* Signed and unsigned integers up to 64 bits wide are supported and encoded
-  properly.
-* Hexadecimal literals are supported.  See `syntax.md`.

 * Capability dependencies for instructions and enums now match 0.99 Rev 32.
+* Very long instructions are supported, up to SPIR-V universal limits.
+* UTF-8 literal strings are supported.
+* Assembler support for numeric literals:
+   * 32 and 64-bit floating point literals are encoded properly.
+   * Signed and unsigned integers of any width up to 64 bits are supported

+     The assembler checks that other literal numbers are non-negative integers.
+     That's the grammar works, at least for now.

 ### Assembler and disassembler
 
-* WIP: Support UTF-8 literal strings.
+* WIP: Fix disassembler support for non-32-bit numeric literals
+* WIP: Fix bug: Assembler can't use extended instructions from
+  two different extended instruction imports.
 * Support 16-bit floating point literals.
-* Support OpenCL extension library.
