 \b Fix a number of bugs related to AVX-512 decorators.
 
+\b Significant improvements to building NASM with Microsoft Visual
+   Studio via \c{Mkfiles/msvc.mak}.
+
 \b To build NASM with custom modifications (table changes) or from the
    git tree now requires Perl 5.6 at the very minimum, quite possibly
    a higher version (Perl 5.24.1 tested.)  There is no requirement to
    have Perl on your system at all if all you want to do is build
    unmodified NASM from source archives.
 
+\b Fix the \c{\{z\}} decorator on AVX-512 \c{VMOVDQ*} instructions.
