+	    The DNS resolver when getting econnrefused from a server
+	    retained an invalid socket so look up towards the next
+	    server(s) also failed.</p>

+	    No resolver backend returns V4Mapped IPv6 addresses any
+	    more. This was inconsistent before, some did, some did
+	    not. To facilitate working with such addresses a new
+	    function <c>inet:ipv4_mapped_ipv6_address/1</c> has been
+	    added.</p>

+	    The type specifications for <c>file:posix/0</c> and
+	    <c>inet:posix/0</c> have been updated according to which
+	    errors file and socket operations should be able to
+	    return.</p>

+	    Fix name resolving in IPv6 only environments when doing
+	    the initial distributed connection.</p>

+	    <p> File operations used to accept <seealso
+	    marker="kernel:file#type-name_all">filenames</seealso>
+	    containing null characters (integer value zero). This
+	    caused the name to be truncated and in some cases
+	    arguments to primitive operations to be mixed up.
+	    Filenames containing null characters inside the filename
+	    are now <em>rejected</em> and will cause primitive file
+	    operations to fail. </p> <p> Also environment variable
+	    operations used to accept <seealso
+	    marker="kernel:os#type-env_var_name">names</seealso> and
+	    <seealso
+	    marker="kernel:os#type-env_var_value">values</seealso> of
+	    environment variables containing null characters (integer
+	    value zero). This caused operations to silently produce
+	    erroneous results. Environment variable names and values
+	    containing null characters inside the name or value are
+	    now <em>rejected</em> and will cause environment variable
+	    operations to fail. </p> <p>Primitive environment
+	    variable operations also used to accept the <c>$=</c>
+	    character in environment variable names causing various
+	    problems. <c>$=</c> characters in environment variable
+	    names are now also <em>rejected</em>. </p> <p>Also
+	    <seealso
+	    marker="kernel:os#cmd/1"><c>os:cmd/1</c></seealso> now
+	    reject null characters inside its <seealso
+	    marker="kernel:os#type-os_command">command</seealso>.
+	    </p> <p><seealso
+	    marker="erts:erlang#open_port/2"><c>erlang:open_port/2</c></seealso>
+	    will also reject null characters inside the port name
+	    from now on.</p>

+	    <p><c>os:putenv</c> and <c>os:getenv</c> no longer access
+	    the process environment directly and instead work on a
+	    thread-safe emulation. The only observable difference is
+	    that it's <em>not</em> kept in sync with libc
+	    <c>getenv(3)</c> / <c>putenv(3)</c>, so those who relied
+	    on that behavior in drivers or NIFs will need to add
+	    manual synchronization.</p> <p>On Windows this means that
+	    you can no longer resolve DLL dependencies by modifying
+	    the <c>PATH</c> just before loading the driver/NIF. To
+	    make this less of a problem, the emulator now adds the
+	    target DLL's folder to the DLL search path.</p>

+	    Fixed connection tick toward primitive hidden nodes
+	    (erl_interface) that could cause faulty tick timeout in
+	    rare cases when payload data is sent to hidden node but
+	    not received.</p>

+	    A new logging API is added to OTP. This is implemented in
+	    the Kernel application, module logger.</p>
+          <p>
+	    Legacy calls to error_logger will be automatically
+	    redirected to the new API.</p>
+          <p>
+	    See the reference manual for module logger, and the
+	    User's Guide for the Kernel application for more
+	    information.</p>

+	    New functionality for implementation of alternative
+	    carriers for the Erlang distribution has been introduced.
+	    This mainly consists of support for usage of distribution
+	    controller processes (previously only ports could be used
+	    as distribution controllers). For more information see
+	    <seealso marker="erts:alt_dist#distribution_module">ERTS
+	    User's Guide ➜ How to implement an Alternative Carrier
+	    for the Erlang Distribution ➜ Distribution
+	    Module</seealso>.</p>

+	    The SSL distribution protocol <c>-proto inet_tls</c> has
+	    stopped setting the SSL option
+	    <c>server_name_indication</c>. New verify funs for client
+	    and server in <c>inet_tls_dist</c> has been added, not
+	    documented yet, that checks node name if present in peer
+	    certificate. Usage is still also yet to be documented.</p>
