+	    When normalizing paths, erl_prim_loader would always
+	    convert backslash to forward slash. This is correct on
+	    Windows, but not on other operating systems.
+	    erl_prim_loader now checks which OS is running before
+	    performing this conversion.</p>

+	    Crashdumps initiated by out-of-memory on process spawn
+	    could cause the beam to segfault during crashdump writing
+	    due to invalid pointers.</p>
+          <p>
+	    The pointers are invalid since the process creation never
+	    finished. This fix removes these processes from the
+	    printouts. Reported by Richard Carlsson.</p>

+	    Crash dumps from 64-bit Erlang machines would have all
+	    memory addresses truncated to 32 bits, which could cause
+	    trouble inspecting processes message queues and stacks in

+	    Threads other than schedulers threads could make thread

+          <p>
+	    A new memory allocation feature called "super carrier"
+	    has been introduced. The super carrier feature can be
+	    used in different ways. It can for example be used for
+	    pre-allocation of all memory that the runtime system
+	    should be able to use.</p>
+          <p>
+	    By default the super carrier is disabled. It is enabled
+	    by passing the <seealso
+	    marker="erts:erts_alloc#MMscs"><c>+MMscs &lt;size in
+	    MB&gt;</c></seealso> command line argument. For more
+	    information see the documentation of the <seealso
+	    marker="erts:erts_alloc#MMsco"><c>+MMsco</c></seealso>,
+	    <seealso
+	    marker="erts:erts_alloc#MMscrfsd"><c>+MMscrfsd</c></seealso>,
+	    <seealso
+	    marker="erts:erts_alloc#MMscrpm"><c>+MMscrpm</c></seealso>,
+	    <seealso
+	    marker="erts:erts_alloc#MMscs"><c>+MMscs</c></seealso>,
+	    <seealso
+	    marker="erts:erts_alloc#Musac"><c>+MMusac</c></seealso>,
+	    and, <seealso
+	    marker="erts:erts_alloc#Mlpm"><c>+Mlpm</c></seealso>
+	    command line arguments in the <seealso
+	    marker="erts:erts_alloc"><c>erts_alloc(3)</c></seealso>
+	    documentation.</p>
+          <p>
+	    Since it is disabled by default there should be no impact
+	    on system characteristics if not used.</p>
+          <p>
+	    This change has been marked as a potential
+	    incompatibility since the returned list when calling
+	    <seealso
+	    marker="erts:erlang#system_info_allocator_tuple"><c>erlang:system_info({allocator,
+	    mseg_alloc})</c></seealso> now also include an
+	    <c>{erts_mmap, _}</c> tuple as one element in the list.</p>

+	    Added erlang:system_info(ets_limit) to provide a way to

+	    <p> Introduced a new guarantee regarding exit signals
+	    from ports: </p><p> If the process calling one of the
+	    synchronous port BIFs listed below is linked to the port
+	    identified by the first argument, and the port exits
+	    before sending the result of the port operation, the exit
+	    signal issued due to this link will be received by the
+	    processes before the BIF returns, or fail with an
+	    exception due to the port not being open. </p><p> The
+	    synchronous port BIFs are: </p> <list> <item><seealso
+	    marker="erlang#port_close/1/"><c>port_close/1</c></seealso></item>

+	    <item><seealso
+	    marker="erlang#port_info/2"><c>erlang:port_info/2</c></seealso></item>
+	    </list> <p> Note that some ports under certain
+	    circumstances unlink themselves from the calling process
+	    before exiting, i.e. even though the process linked
+	    itself to the port there might be no link triggering an
+	    exit signal. </p> <p>Characteristics impact: The return
+	    or exception from the synchronous port BIF will be
+	    delayed if the port simultaneously exit due to some issue
+	    unrelated to the outstanding synchronous port BIF call.
+	    In all other cases characteristics are unchanged. </p>
