        * Version 5.3.0.
 
+       Minor performance improvements and cleanups for "touch".
+       * src/touch.c (posix_date): Remove; not needed as a static var.
+       All uses rewritten.
+       (touch): Use new futimens function to operate more efficiently
+       in some cases.  Don't stat/fstat existing file when
+       (!amtime_now && change_times == (CH_ATIME | CH_MTIME)); the
+       old time stamps aren't needed in that case.
+       (main): change_times is int, not bool.  Simplify test for
+       change_times.

        * src/install.c (usage): Avoid usage that runs afoul of Docbook
        translation.  Problem reported by Eric S. Raymond.
