+<p>
+When using <code>-buildmode=c-archive</code> or
+<code>-buildmode=c-shared</code> to build an archive or a shared
+library, the handling of signals has changed.
+In Go 1.5 the archive or shared library would install a signal handler
+for most signals.
+In Go 1.6 it will only install a signal handler for the
+synchronous signals needed to handle run-time panics in Go code:
+SIGBUS, SIGFPE, SIGSEGV.
+See the <a href="/pkg/os/signal">os/signal</a> package for more
+details.
