+	    Fix bug where gethostname would incorrectly fail with
+	    enametoolong on Linux.</p>

+	    Fix bug causing <c>code:is_module_native</c> to falsely
+	    return true when <c>local</c> call trace is enabled for
+	    the module.</p>

+          <p>
+	    Since Unicode is now allowed in atoms an extra check is
+	    needed for node names, which are restricted to Latin-1.</p>

+	    Own Id: OTP-13805</p>
+        </item>
+        <item>
+	    <p>Replaced usage of deprecated symbolic <seealso
+	    marker="erts:erlang#type-time_unit"><c>time
+	    unit</c></seealso> representations.</p>

+        <item>
+	    <p><c>file:write_file(Name, Data, [raw])</c> would turn
+	    <c>Data</c> into a single binary before writing. This
+	    meant it could not take advantage of the <c>writev()</c>
+	    system call if it was given a list of binaries and told
+	    to write with <c>raw</c> mode.</p>
+          <p>
+	    Own Id: OTP-13909</p>
+        </item>
+        <item>
+	    <p>The performance of the <c>disk_log</c> has been
+	    somewhat improved in some corner cases (big items), and
+	    the documentation has been clarified. </p>

+        </item>
+        <item>
+	    <p>Functions for detecting changed code has been added.
+	    <c>code:modified_modules/0</c> returns all currently
+	    loaded modules that have changed on disk.
+	    <c>code:module_status/1</c> returns the status for a
+	    module. In the shell and in <c>c</c> module, <c>mm/0</c>
+	    is short for <c>code:modified_modules/0</c>, and
+	    <c>lm/0</c> reloads all currently loaded modules that
+	    have changed on disk.</p>

+        <item>
+          <p>
+	    Introduce an event manager in Erlang to handle OS
+	    signals. A subset of OS signals may be subscribed to and
+	    those are described in the Kernel application.</p>

+        <item>
+	    <p> Sockets can now be bound to device (SO_BINDTODEVICE)
+	    on platforms where it is supported. </p> <p> This has
+	    been implemented e.g to support VRF-Lite under Linux; see
+	    <url
+	    href="https://www.kernel.org/doc/Documentation/networking/vrf.txt">
+	    VRF </url>, and GitHub pull request <url
+	    href="https://github.com/erlang/otp/pull/1326">#1326</url>.

+          <p>
+	    Added option to store shell_history on disk so that the
+	    history can be reused between sessions.</p>

+        <item>
+	    <p> The size of crash reports created by
+	    <c>gen_server</c>, <c>gen_statem</c> and <c>proc_lib</c>
+	    is limited with aid of the Kernel application variable
+	    <c>error_logger_format_depth</c>. The purpose is to limit
+	    the size of the <c>error_logger</c> process when
+	    processes with huge message queues or states crash. </p>
+	    <p> The new function
+	    <c>error_logger:get_format_depth/0</c> can be used to
+	    retrieve the value of the Kernel application variable
+	    <c>error_logger_format_depth</c>. </p>

+	    <p> One of the ETS tables used by the <c>global</c>
+	    module is created with <c>{read_concurrency, true}</c> in
+	    order to reduce contention. </p>

+	    Warnings have been added to the relevant documentation
+	    about not using un-secure distributed nodes in exposed
+	    environments.</p>
