+NEWS file ('C-h n' within emacs) for changes since the last release,
+although this is not yet complete.
 
+This build uses the timerfd functions that were introduced in
+cygwin-3.0.0, so it will not run on earlier releases of Cygwin.  And
+it will not run well on Cygwin releases prior to cygwin-3.0.3, which
+contains fixes for some timer-related bugs.
