-	    The type specifications for <c>file:posix/0</c> and

-	    errors file and socket operations should be able to
-	    return.</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

-	    </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

-	    <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>

-	    <p>A new logging API is added to Erlang/OTP, see the
-	    <seealso
-	    marker="kernel:logger"><c>logger(3)</c></seealso> manual
-	    page, and section <seealso
-	    marker="kernel:logger_chapter">Logging</seealso> in the
-	    Kernel User's Guide.</p>
-	    <p>Calls to <c>error_logger</c> are automatically
-	    redirected to the new API, and legacy error logger event
-	    handlers can still be used. It is, however, recommended
-	    to use the Logger API directly when writing new code.</p>
-	    <p>Notice the following potential incompatibilities:</p>
-	    <list> <item><p>Kernel configuration parameters
-	    <c>error_logger</c> still works, but is overruled if the
-	    default handler's output destination is configured with
-	    Kernel configuration parameter <c>logger</c>.</p> <p>In
-	    general, parameters for configuring error logger are
-	    overwritten by new parameters for configuring
-	    Logger.</p></item> <item><p>The concept of SASL error
-	    logging is deprecated, meaning that by default the SASL
-	    application does not affect which log events are
-	    logged.</p> <p>By default, supervisor reports and crash
-	    reports are logged by the default Logger handler started
-	    by Kernel, and end up at the same destination (terminal
-	    or file) as other standard log event from Erlang/OTP.</p>
-	    <p>Progress reports are not logged by default, but can be
-	    enabled with the Kernel configuration parameter
-	    <c>logger_progress_reports</c>.</p> <p>To obtain
-	    backwards compatibility with the SASL error logging
-	    functionality from earlier releases, set Kernel
-	    configuration parameter <c>logger_sasl_compatible</c> to
-	    <c>true</c>. This prevents the default Logger handler
-	    from logging any supervisor-, crash-, or progress
-	    reports. Instead, SASL adds a separate Logger handler
-	    during application start, which takes care of these log
-	    events. The SASL configuration parameters
-	    <c>sasl_error_logger</c> and <c>sasl_errlog_type</c>
-	    specify the destination (terminal or file) and severity
-	    level to log for these events.</p></item></list>

-	    <c>gen_sctp:connect_init/4</c> or rather connect in
-	    <c>inet_drv.c</c> for SCTP has been fixed to not check
-	    the write file descriptor for writeability after a
-	    connect, since for SCTP (SOCK_SEQPACKET) that property
-	    does not seem to be any kind of indicator for when a
-	    connect has finished. This fixes connects that the OS
-	    returned as "in progress" that was misinterpreted by
-	    <c>gen_sctp:connect_init</c> as failed.</p>

-	    <p>The file driver has been rewritten as a NIF,

-	    incompatibilities are:</p> <list> <item><p>The
-	    <c>use_threads</c> option for <c>file:sendfile/5</c> no
-	    longer has any effect; we either use non-blocking
-	    <c>sendfile(2)</c> or fall back to <c>file:read</c> +
-	    <c>gen_tcp:send</c>. </p></item> <item><p>The
-	    file-specific DTrace probes have been removed. The same
-	    effect can be achieved with normal tracing together with
-	    the <c>nif__entry</c>/<c>nif__return</c> probes to track

-	    <p>The I/O polling functionality of erts has been
-	    re-written to better make use of the OSs polling
-	    mechanisms. This change means that erts will now always
-	    prefer to use a kernel-polling mechanism if possible.
-	    Also all of the I/O polling has been moved to dedicated
-	    threads instead of being placed in the scheduler
-	    loops.</p> <p>As a result of this, the <c>erl</c> options
-	    <c>+K</c> and <c>+secio</c> have been removed. It is
-	    still possible to disable kernel-poll, but it has to be
-	    done at compile time through the configure option
-	    <c>--disable-kernel-poll</c>.</p> <p>The new <c>erl</c>
-	    options <seealso marker="erl#+IOt"><c>+IOt</c></seealso>
-	    and <seealso marker="erl#+IOp"><c>+IOp</c></seealso> can
-	    be used to change how many IO poll threads and poll sets
-	    that erts should use. See their respective documentation
-	    for more details.</p>

-	    <p>Truly asynchronous auto-connect. Earlier, when
-	    <c>erlang:send</c> was done toward an unconnected node,
-	    the function would not return until the connection setup
-	    had completed (or failed). Now the function returns
-	    directly after the signal has been enqueued and the
-	    connection setup started.</p>
-	    <p>The same applies to all distributed operations that
-	    may trigger auto-connect, i.e. <c>'!'</c>, <c>send</c>,
-	    <c>link</c>, <c>monitor</c>, <c>monitor_node</c>,
-	    <c>exit/2</c> and <c>group_leader</c>.</p>
-	    <p>The interface for all these functions are unchanged as
-	    they do not return connection failures. The only
-	    exception is <c>erlang:monitor</c> where a <em>possible
-	    incompatibility</em> is introduced: An attempt to monitor
-	    a process on a primitive node (such as erl_interface or
-	    jinterface), where remote process monitoring is not
-	    implemented, will no longer fail with <c>badarg</c>
-	    exception. Instead a monitor will be created, but it will
-	    only supervise the connection to the node.</p>

-	    New functionality for implementation of alternative

-	    <p>Support for "tuple calls" have been removed from the

-	    unsupported feature which allowed the module argument for
-	    an apply operation to be a tuple: <c>Var = dict:new(),
-	    Var:size()</c>. This "feature" frequently caused
-	    confusion, especially when such call failed. The
-	    stacktrace would point out functions that don't exist in
-	    the source code.</p>
-	    <p>For legacy code that need to use parameterized modules
-	    or tuple calls for some other reason, there is a new
-	    compiler option called <c>tuple_calls</c>. When this
-	    option is given, the compiler will generate extra code
-	    that emulates the old behavior for calls where the module
-	    is a variable.</p>
