+	    The '-path' flag to 'erl' has been documented. This flag
+	    replaces the path specified in the boot script. It has
+	    always existed, but was earlier only documented in SASL
+	    (script).</p>

+	    The <c>call_time</c> tracing functionality internally
+	    used a time based on OS system time in order to measure
+	    call time which could cause erroneous results if OS
+	    system time was changed during tracing.</p>
+          <p>
+	    This functionality now use Erlang monotonic time in order
+	    to measure time. Besides fixing the erroneous results due
+	    to OS system time being used, the results are often also
+	    better since Erlang monotonic time often has better
+	    accuracy and precision.</p>

+	    Fix behaviour of -delay_write command line switch of
+	    epmd, which is used for debugging - in some cases epmd
+	    was sleeping twice the requested amount of time.</p>

+	    Fix race between timeout and exit signal that could cause
+	    a process to ignore the exit signal and continue
+	    execution. Bug exist since OTP 18.0.</p>

+	    Fix bug in <c>erlang:halt/1,2</c> for large exit status
+	    values, causing either <c>badarg</c> (on 32-bit) or exit
+	    with a crash dump and/or core dump (on 64-bit). Make
+	    <c>erlang:halt/1,2</c> tolerate any non negative integer
+	    as exit status and truncate high order bits if the OS
+	    does not support it.</p>

+	    A workaround for an issue with older gcc versions (less
+	    than 5) and inline assembly on 32-bit x86 caused an
+	    emulator crash when it had been compiled with a newer gcc
+	    version. An improved <c>configure</c> test, run when
+	    building OTP, now detects whether the workaround should
+	    be used or not.</p>

+	    Time warp safety improvements.</p>
+          <p>
+	    Introduced the options <c>monotonic_timestamp</c>, and
+	    <c>strict_monotonic_timestamp</c> to the trace,

+	    since the already existing <c>timestamp</c> option is not
+	    time warp safe.</p>
+          <p>
+	    Introduced the option <c>safe_fixed_monotonic_time</c> to
+	    <c>ets:info/2</c> and <c>dets:info/2</c>. This since the
+	    already existing <c>safe_fixed</c> option is not time

+	    Improved the gcc inline assembly implementing double word

+	    An optimization preventing a long wait for a scheduler
+	    thread looking up information about a process executing
+	    on another scheduler thread had unintentionally been lost
+	    in erts-5.10 (OTP R16A). This optimization has now been
+	    reintroduced.</p>
