-	    <p>The handling of <c>on_load</c> functions has been
-	    improved. The major improvement is that if a code upgrade
-	    fails because the <c>on_load</c> function fails, the
-	    previous version of the module will now be retained.</p>

-          <p>
-	    A process could terminate due to exit signal even though
-	    <c>process_flag(trap_exit,true)</c> had returned. A very
-	    specific timing between call to <c>process_flag/2</c> and
-	    exit signal from another scheduler was required for this
-	    to happen.</p>

-        <item>
-          <p>
-	    The tracing support has been extended to allow a <seealso
-	    marker="erl_tracer">tracer module</seealso> to be the
-	    trace event handler instead of a process or port. The
-	    <seealso marker="erl_tracer">tracer module</seealso>
-	    makes it possible for trace tools to filter or manipulate
-	    trace event data without the trace event first haing to
-	    be copied from the traced process or port.</p>
-          <p>
-	    With the introduction of this feature,
-	    <c>erlang:trace(all|existing, _, _)</c> now also returns
-	    the tracer process as part of the number of processes on
-	    which tracing is enabled. The is incompatible with the
-	    previous releases.</p>

-        <item>
-          <p>
-	    Introduce LTTng tracing of Erlang Runtime System</p>
-          <p>
-	    For LTTng to be enabled OTP needs to be built with
-	    configure option <c>--with-dynamic-trace=lttng</c>.</p>
-          <p>
-	    This feature introduces tracepoints for schedulers,
-	    drivers, memory carriers, memory and async thread pool.</p>
-	    <p> For a list of all tracepoints, see <seealso
-	    marker="runtime_tools:LTTng">Runtime Tools User's
-	    Guide</seealso> .</p>

-          <p>
-	    Add microstate accounting</p>
-          <p>
-	    Microstate accounting is a way to track which state the
-	    different threads within ERTS are in. The main usage area
-	    is to pin point performance bottlenecks by checking which
-	    states the threads are in and then from there figuring
-	    out why and where to optimize.</p>
-          <p>
-	    Since checking whether microstate accounting is on or off
-	    is relatively expensive only a few of the states are
-	    enabled by default and more states can be enabled through
-	    configure.</p>
-          <p>
-	    There is a convinence module called msacc that has been
-	    added to runtime_tools that can assist in gathering and
-	    interpreting the data from Microstate accounting.</p>
-          <p>
-	    For more information see <seealso
-	    marker="erts:erlang#statistics_microstate_accounting">erlang:statistics(microstate_accounting,
-	    _)</seealso> and the <seealso
-	    marker="runtime_tools:msacc">msacc</seealso> module in
-	    runtime_tools.</p>

-          <p>
-	    The port of Erlang/OTP to the realtime operating system
-	    OSE has been removed.</p>

-        <item>
-          <p>
-	    Sharing preserved copy for messages and exit signals</p>
-          <p>
-	    Enable sharing preserved copy with configure option
-	    <c>--enable-sharing-preserving</c>. This will preserve
-	    sharing, within the process, when communication with
-	    other processes in the Erlang node. There is a trade-off,
-	    the copy is more costly but this cost can be reclaimed if
-	    there is a lot of sharing in the message. With this
-	    feature enabled literals will not be copied in a send
-	    except during a purge phase of the module where the
-	    literals are located.</p>

-	    Added <seealso
-	    marker="kernel:os#perf_counter/1">os:perf_counter/1</seealso>.</p>
-          <p>
-	    The perf_counter is a very very cheap and high resolution
-	    timer that can be used to timestamp system events. It
-	    does not have monoticity guarantees, but should on most
-	    OS's expose a monotonous time.</p>

-          <p>
-	    Support for a fragmented young heap generation. That is,
-	    the young heap generation can consist of multiple non
-	    continuous memory areas. The main reason for this change
-	    is to avoid extra copying of messages that could not be
-	    allocated directly on the receivers heap.</p>

-          <p>
-	    Erlang linked-in driver can now force the call to
-	    open_port to block until a call to erl_drv_init_ack is
-	    made inside the driver. This is useful when you want to
-	    do some asynchronous initialization, for example getting
-	    configuration from a pipe, and you want the initial
-	    open_port call to fail if the configuration is incomplete
-	    or wrong. See the erl_driver documentation for more
-	    details on the API.</p>

-	    Erlang linked-in drivers can now set their own pid's as
-	    seen in <c>erlang:port_info/1</c> by using the
-	    <c>erl_drv_set_pid</c> function. For more details see the
-	    erl_driver documentation.</p>

-          <p>
-	    The functionality behind <c>erlang:open_port/2</c> when
-	    called with spawn or spawn_executable has been redone so
-	    that the forking of the new program is done in a separate
-	    process called erl_child_setup. This allows for a much
-	    more robust implementation that uses less memory and does
-	    not block the entire emulator if the program to be
-	    started is on an un-accessible NFS. Benchmarks have shown
-	    this approach to be about 3-5 times as fast as the old
-	    approach where the fork/vfork was done by erts. This is a
-	    pure stability and performance fix, however some error
-	    messages may have changed, which is why it is marked as a
-	    backwards incompatible change.</p>

-	    When the <c>'procs'</c> trace flag is enabled, a

-	    remains, but as it is generated by the process that did
-	    the spawn, it is not guaranteed that it is ordered with
-	    other trace events from the newly spawned process. So
-	    when tracking the lifetime of a process this new event
-	    should be used as the creation event.</p>
-          <p>

-	    The erts internal tracing support has been changed to
-	    have much less overhead and be more scalable.</p>
-          <p>
-	    This rewrite does not break any backwards
-	    incompatabilities, but it does change the ordering of
-	    some trace messages when compared to previous releases.
-	    It should be noted that this only applies to trace
-	    messages sent to processes or ports, it does not apply to
-	    the new tracer module. However in future releases they
-	    may also be effected by this.</p>
-          <p>
-	    Trace messages are only guaranteed to be ordered from one
-	    traced process or port. In previous releases this was not
-	    visible as a <c>'send'</c> trace message would always
-	    arrive before the corresponding <c>'receive'</c> trace
-	    message that is no longer always the case. This also
-	    means that timestamped trace messages may seem to arrive
-	    out of order as the timestamp is taken when the event is
-	    triggered and not when it is put in the queue of the
-	    tracer.</p>

-	    <p>This feature also introduces an incompatible change in
-	    trace tags. The trace tags <c>gc_start</c> and
-	    <c>gc_end</c> has been split into <c>gc_minor_start</c>,
