+	    <p><c>gen_statem</c> improvements.</p> <p> When using an
+	    exception that is valid but not allowed in a state enter
+	    call, the reason has been changed from
+	    <c>{bad_action_from_state_function,Action}</c> to
+	    <c>{bad_state_enter_action_from_state_function,Action}</c>.
+	    </p><p> Timer parsing has been improved. Many erroneous
+	    timeout tuples was not handled correctly. </p><p> The
+	    documentation has been updated, in particular the User's
+	    Guide and the pointer to it from the Reference Manual is
+	    much more obvious. </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
+	    from now on.</p>

+	    A sys debug fun of type {Fun,State} should not be
+	    possible to install twice. This was, however, possible if
+	    the current State was 'undefined', which was mistaken for
+	    non-existing fun. This has been corrected.</p>

+	    The <c>gen_server</c> has gotten a new callback
+	    <c>handle_continue/2</c> for check pointing the state.
+	    This is useful at least when implementing behaviours on
+	    top of <c>gen_server</c> and for some start up scenarios.</p>

+	    <p> The semantics of timeout parameter
+	    <c>{clean_timeout,infinity}</c> to
+	    <c>gen_statem:call/3</c> has been changed to use a proxy
+	    process for the call. With this change
+	    <c>clean_timeout</c> implicates a proxy process with no
+	    exceptions. This may be a hard to observe
+	    incompatibility: in the presence of network problems a
+	    late reply could arrive in the caller's message queue
+	    when catching errors. That will not happen after this
+	    correction. </p><p> The semantics of timeout parameter
+	    <c>infinity</c> has not been changed. </p>

+        </item>
+        <item>
+	    <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>

+	    <p> Functions <c>rand:uniform_real/0</c> and
+	    <c>rand:uniform_real_s/1</c> have been added. They
+	    produce uniformly distributed numbers in the range <c>0.0
+	    =&lt; X &lt; 1.0</c> that are as close to random real
+	    numbers as Normalized IEEE 754 Double Precision allows.
+	    Because the random real number exactly <c>0.0</c> is
+	    infinitely improbable they will never return exactly
+	    <c>0.0</c>. </p><p> These properties are useful when you
+	    need to call for example <c>math:log(X)</c> or <c>1 /
+	    X</c> on a random value <c>X</c>, since that will never
+	    fail with a number from these new functions. </p>

+	    <p>This is an incompatible change, but note that the use
+	    of backslashes in wildcards would already work
+	    differently on Windows and Unix. Existing calls to
+	    <c>filelib:wildcard()</c> needs to be updated. On

+	    <p> The new functions <c>io_lib:fwrite/3</c> and
+	    <c>io_lib:format/3</c> take a third argument, an option
+	    list. The only option is <c>chars_limit</c>, which is
+	    used for limiting the number of returned characters. The
+	    limit is soft, which means that the number of returned
+	    characters exceeds the limit with at most a smallish
+	    amount. If the limit is set, the functions
+	    <c>format/3</c> and <c>fwrite/3</c> try to distribute the
+	    number of characters evenly over the control sequences
+	    <c>pPswW</c>. Furthermore, the control sequences
+	    <c>pPwP</c> try to distribute the number of characters
+	    evenly over substructures. </p> <p> A modification of the
+	    control sequences <c>pPwW</c> is that even if there is no
+	    limit on the number of returned characters, all
+	    associations of a map are printed to the same depth. The
+	    aim is to give a more consistent output as the order of
+	    map keys is not defined. As before, if the depth is less
+	    than the number of associations of a map, the selection
+	    of associations to print is arbitrary. </p>
