+- Update to version 2.15.05:
+  + Fix {%ifid $} and {%ifid $$} incorrectly being treated as true.
+  + Add {--reproducible} option to suppress NASM version numbers
+    and timestamps in output files. See {opt-reproducible}.
+

+Mon Aug 24 20:20:20 UTC 2020 - Dirk Mueller <dmueller@suse.com>
+
+- 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}.
