++	    Changed default OS monotonic clock source chosen at build
++	    time. This in order to improve performance. The behavior
++	    will now on most systems be that (both OS and Erlang)
++	    monotonic time stops when the system is suspended.</p>
++          <p>
++	    If you prefer that monotonic time elapse during suspend
++	    of the machine, you can pass the command line argument
++	    <c>--enable-prefer-elapsed-monotonic-time-during-suspend</c>
++	    to <c>configure</c> when building Erlang/OTP. The
++	    configuration stage will try to find such a clock source,
++	    but might not be able to find it. Note that there might
++	    be a performance penalty associated with such a clock
++	    source.</p>
