- update to 2.15.4:
* More sensible handling of the case where one single-line macro
definition will shadow another.
* Add special preprocessor tokens \c{%*?} and \c{%*??} that expand
like \c{%?} and \c{%??} in single-line macros only. See
\k{selfref%*?}.
* Fix SSE instructions not being recognized with an explicit memory
operation size (e.g. \c{movsd qword [eax],xmm0}).
* The \c{-L+} option no longer enables \c{-Lw}, which is mainly
useful to debug NASM crashes. See \k{opt-L}.
* The NASM-only RDOFF output format backend, which has been broken
since at least NASM 2.14, has been disabled. The RDOFF tools are
scheduled to be removed from the NASM distribution in NASM 2.16. If
you have a concrete use case for RDOFF, please file a NASM bug report
at \W{https://bugs.nasm.us/}\c{https://bugs.nasm.us/} as soon as
possible. See \k{rdffmt}.
