	    It is no longer possible to have <c>{Mod,Vsn}</c> in the
	    'modules' list in a .app file.</p>
          <p>
	    This was earlier possible, although never documented in
	    the .app file reference manual. It was however visible in
	    the documentation of <c>application:load/[1,2]</c>, where
	    the same term as in a .app file can be used as the first
	    argument.</p>
          <p>
	    The possibility has been removed since the <c>Vsn</c>
	    part was never used.</p>

        <item>
	    <p> The type <c>ascii_string()</c> in the <c>base64</c>
	    module has been corrected. The type
	    <c>file:file_info()</c> has been cleaned up. The type
	    <c>file:fd()</c> has been made opaque in the

	    A boolean socket option 'ipv6_v6only' for IPv6 sockets
	    has been added. The default value of the option is OS
	    dependent, so applications aiming to be portable should
	    consider using <c>{ipv6_v6only,true}</c> when creating an
	    <c>inet6</c> listening/destination socket, and if
	    neccesary also create an <c>inet</c> socket on the same
	    port for IPv4 traffic. See the documentation.</p>

	    with bind, while the rest are to be bound using
	    sctp_bindx. At least Linux supports adding address of
	    mixing families. Make inet_set_faddress function
	    available also when HAVE_SCTP is not defined, since we
	    use it to find an address for bind to be able to mix ipv4
	    and ipv6 addresses. Thanks to Tomas Abrahamsson</p>

	    Driver output has been corrected so output of large
	    binaries (> 4 GiB) now does not silently fail or crash
	    the emulator, but either outputs the binary or fails the
	    call. This means that writing a binary > 4 Gib to file

	    scatter/gather I/O buffer segment lengths of 32 bits)
	    fails. The behaviour may change in the future to always

	    returns a list of its callbacks.</p>
          <p>
	    This function is now automatically generated using the
	    '-callback' specs. An error is returned by lint if user
	    defines both '-callback' attributes and the
	    behaviour_info/1 function. If no type info is needed for
	    a callback use a generic spec for it. Add '-callback'
	    attribute to language syntax</p>
          <p>
	    Behaviours may define specs for their callbacks using the
	    familiar spec syntax, replacing the '-spec' keyword with
	    '-callback'. Simple lint checks are performed to ensure
	    that no callbacks are defined twice and all types
	    referred are declared.</p>
          <p>

	    After the addition of unicode_binary() to the

	    erroneous or incomplete specs in some functions of the
	    'code' module. The culprit was hard-coded information in
	    erl_bif_types for functions of this module, which were
	    not updated. Since these functions have proper specs
	    these days and code duplication (pun intended) is never a
	    good idea, their type information was removed from
	    erl_bif_types.</p>
          <p>
	    While doing this, some erroneous comments were fixed in
	    the code module and also made sure that the code now runs
	    without dialyzer warnings even when the
	    -Wunmatched_returns option is used.</p>
          <p>
	    Some cleanups were applied to erl_bif_types too.</p>

	    The Erlang VM now supports Unicode filenames. The feature
	    is turned on by default on systems where Unicode
	    filenames are mandatory (Windows and MacOSX), but can be
	    enabled on other systems with the '+fnu' emulator option.
	    Enabling the Unicode filename feature on systems where it
	    is not default is however considered experimental and not
	    to be used for production. Together with the Unicode file
	    name support, the concept of "raw filenames" is
	    introduced, which means filenames provided without
	    implicit unicode encoding translation. Raw filenames are
	    provided as binaries, not lists. For further information,
	    see stdlib users guide and the chapter about using
	    Unicode in Erlang. Also see the file module manual page.</p>

	    The loading of native code was not properly atomic in the
	    SMP emulator, which could cause crashes. Also a per-MFA
	    information table for the native code has now been
	    protected with a lock since it turns that it could be
	    accessed concurrently in the SMP emulator. (Thanks to
	    Mikael Pettersson.)</p>

	    The resolver routines failed to look up the own node name
	    as hostname, if the OS native resolver was erroneously
	    configured, bug reported by Yogish Baliga, now fixed.</p>
          <p>
	    The resolver routines now tries to parse the hostname as
	    an IP string as most OS resolvers do, unless the native
	    resolver is used.</p>
          <p>
	    The DNS resolver inet_res and file resolver inet_hosts
	    now do not read OS configuration files until they are
	    needed. Since the native resolver is default, in most
	    cases they are never needed.</p>
          <p>
	    The DNS resolver's automatic updating of OS configuration
	    file data (/etc/resolv.conf) now uses the 'domain'
	    keyword as default search domain if there is no 'search'
	    keyword.</p>

	    <p> The DNS resolver client inet_res has been rewritten,
	    documented and released. See inet_res(3) and Erts User's
	    Guide: Inet configuration. </p><p> It can formally not be
	    incompatible with respect to earlier versions since there
	    was no earlier official version. However it was used
	    before and some details have changed. </p><p>
	    Configuration now initializes from /etc/resolv.conf and
	    /etc/hosts on all unix platforms regardless of which
	    distribution mode the node is started in. The directory
	    (/etc) these files are supposed to reside in can be
	    changed via an environment variable. These configuration
	    file locations can also be changed in the inet
	    configuration. The files are monitored for change and
	    re-read, which makes a few resolver configuration
	    variables out of application control. The /etc/hosts
	    entries have now their own cache table that is shadowed
	    (with lookup method 'file' is used) by the application
	    configured host entries. This problem (that inet_res
	    configuration only worked for distribution mode long
	    names) was among other reported by Matthew O'Gorman many
	    moons ago. </p><p> The lookup methods are still 'native'
	    only per default. Resolver configuration is done on all
	    Unix platforms just to get a usable configuration for
	    direct calls to inet_res. </p><p> The functions
	    <c>inet_res:nslookup/3..5</c> and
	    <c>inet_res:nnslookup/4..4</c> are no longer recommended
	    to use, instead use <c>inet_res:lookup/3..5</c> and
	    <c>inet_res:resolve/3..5</c> which provide clearer
	    argument types and the possibility to override options in
	    the call. </p><p> Users of previous unsupported versions
	    of inet_res have included internal header files to get to
	    the internal record definitions in order to examine DNS
	    replies. This is still unsupported and there are access
	    functions in inet_dns to use instead. These are
	    documented in inet_res(3). </p><p> Bug fix: a compression
	    reference loop would make DNS message decoding loop
	    forever. Problem reported by Florian Weimer. </p><p> Bug
	    fix and patch suggestion by Sergei Golovan: configuring
	    IPv6 nameservers did not work. His patch (as he warned)
	    created many UDP sockets; one per nameserver. This has
	    been fixed in the released version. </p><p> Improvement:
	    <c>inet_res</c> is now EDNS0 capable. The current
	    implementation is simple and does not probe and cache
	    EDNS info for nameservers, which a fully capable
	    implementation probably should do. EDNS has to be enabled
	    via resolver configuration, and if a nameserver replies
	    that it does not support EDNS, <c>inet_res</c> falls back
	    to a regular DNS query. </p><p> Improvement: now
	    <c>inet_res</c> automatically falls back to TCP if it
	    gets a truncated answer from a nameserver. </p><p>
	    Warning: some of the ancient and exotic record types
	    handled by <c>inet_res</c> and <c>inet_dns</c> are not
	    supported by current versions of BIND, so they could not
	    be tested after the rewrite, with reasonable effort, e.g
	    MD, MF, NULL, and SPF. The risk for bugs in these
	    particular records is still low since their code is
	    mostly shared with other tested record types. </p>

	    Added functionality to get higher resolution timestamp
	    from system. The erlang:now function returns a timestamp
	    that's not always consistent with the actual operating
	    system time (due to resilience against large time changes
	    in the operating system). The function os:timestamp/0 is
	    added to get a similar timestamp as the one being
	    returned by erlang:now, but untouched by Erlangs time
	    correcting and smoothing algorithms. The timestamp
	    returned by os:timestamp is always consistent with the
	    operating systems view of time, like the calendar
	    functions for getting wall clock time, but with higher
	    resolution. Example of usage can be found in the os
	    manual page.</p>

	    The error behavior of gen_tcp and gen_udp has been

	    address versus socket address family. Other corner cases
	    for IP address string host names combined with not using
	    the native (OS) resolver (which is not default) has also
	    been changed to return {error,nxdomain} instead of
	    {error,einval}. Those changes just may surprise old
	    existing code. gen_tcp:listen/2 and gen_udp:open/2 now
	    fails for conflicting local address versus socket address
	    family instead of trying to use an erroneous address.

	    followed by a failing gen_tcp:recv() could in some cases
	    cause the port to linger after being closed.</p>

	    <p>Processes spawned using <c>proc_lib</c> (including
	    <c>gen_server</c> and other library modules that use
	    <c>proc_lib</c>) no longer keep the entire argument list
	    for the initial call, but only the arity.</p>
	    <p>Also, if <c>proc_lib:spawn/1</c> is used to spawn a
	    fun, the actual fun is not kept, but only module,
	    function name, and arity of the function that implements
	    the fun.</p>
	    <p>The reason for the change is that keeping the initial
	    fun (or a fun in an argument list), would prevent
	    upgrading the code for the module. A secondary reason is
	    that keeping the fun and function arguments could waste a
	    significant amount of memory.</p>
	    <p>The drawback with the change is that the crash reports
	    will provide less precise information about the initial
	    call (only <c>Module:Function/Arity</c> instead of
	    <c>Module:Function(Arguments)</c>). The function
	    <c>proc_lib:initial_call/1</c> still returns a list, but
	    each argument has been replaced with a dummy atom.</p>

	    <p>The functions io:columns/0, io:columns/1, io:rows/0
	    and io:rows/1 are added to allow the user to get
	    information about the terminal geometry. The shell takes
	    some advantage of this when formatting output. For
	    regular files and other io-devices where height and width
	    are not applicable, the functions return
	    {error,enotsup}.</p>
	    <p>Potential incompatibility: If one has written a custom
	    io-handler, the handler has to either return an error or
	    take care of io-requests regarding terminal height and
	    width. Usually that is no problem as io-handlers, as a
	    rule of thumb, should give an error reply when receiving
	    unknown io-requests, instead of crashing.</p>

	    was also a bug causing it to create malformed DNS queries

	    suggested by Scott Lystig Fritchie. The code has also
	    been corrected to look up cached RRs in the same search

          <p>When setting the kernel configuration parameter

          <p>An interface towards the SCTP Socket API Extensions
            has been implemented.It is an Open Source patch courtesy
            of Serge Aleynikov and Leonid Timochouk. The Erlang code
            parts has been adapted by the OTP team, changing the
            Erlang API somewhat.</p>
          <p>The Erlang interface consists of the module
            <c>gen_sctp</c> and an include file
            <c>-include_lib("kernel/include/inet_sctp.hrl").</c> for
            option record definitions. The <c>gen_sctp</c> module is
            documented.</p>
          <p>The delivered Open Source patch, before the OTP team
            rewrites, was written according to
            <url href="http://tools.ietf.org/html/draft-ietf-tsvwg-sctpsocket-13">http://tools.ietf.org/html/draft-ietf-tsvwg-sctpsocket-13</url>
            and was claimed to work fine, tested on Linux Fedora Core
            5.0 (kernel 2.6.15-2054 or later) and on Solaris 10 and
            11. The OTP team rewrites used the same standard document
            but might have accidentally broken some functionality. If
            so, it will soon be patched to working state. The tricky
            parts in C and the general design has essentially not
            changed. During the rewrites the code was hand tested on
            SuSE Linux Enterprise Server 10, and briefly on Solaris
            10. Feedbach on code and docs is very much
            appreciated.</p>
          <p>The SCTP interface is in beta state. It has only been
            hand tested and has no automatic test suites in OTP
            meaning everything is most certainly not tested. Socket
            active mode is broken. IPv6 is not tested. The documentation
            has been reworked due to the API changes,
            but has not been proofread after this.</p>
          <p>Thank you from the OTP team to Serge Aleynikov and
            Leonid Timochouk for a valuable contribution. We hope we
            have not messed it up too much.</p>

          <p>To help Dialyzer find more bugs, many functions in the
            Kernel and STDLIB applications now only accept arguments
            of the type that is documented.</p>
          <p>For instance, the functions <c>lists:prefix/2</c> and
            <c>lists:suffix/2</c> are documented to only accept lists
            as their arguments, but they actually accepted anything
            and returned <c>false</c>. That has been changed so that
            the functions cause an exception if one or both arguments
            are not lists.</p>
          <p>Also, the <c>string:strip/3</c> function is documented
            to take a character argument that is a character to strip
            from one or both ends of the string. Given a list instead
            of a character, it used to do nothing, but will now cause
            an exception.</p>
          <p>Dialyzer will find most cases where those functions
            are passed arguments of the wrong type.</p>

            Despite that, the configuration parameter
            <c>start_ddll</c> for the Kernel application was still
            obeyed, which would cause the erl_ddll server to be

          <p>Previously <c>unlink/1</c> and <c>erlang:demonitor/2</c>
            behaved completely asynchronous. This had one undesirable
            effect, though. You could never know when you were
            guaranteed <em>not</em> to be affected by a link that you
            had unlinked or a monitor that you had demonitored.</p>
          <p>The new behavior of <c>unlink/1</c> and
            <c>erlang:demonitor/2</c> can be viewed as two operations
            performed atomically. Asynchronously send an unlink
            signal or a demonitor signal, and ignore any future
            results of the link or monitor.</p>
          <p><em>NOTE</em>: This change can cause some obscure code
            to fail which previously did not. For example, the
            following code might hang:</p>
          <code type="none">
            Mon = erlang:monitor(process, Pid),

            %% We were previously guaranteed to get a down message
            %% (since we exited the process ourself), so we could
            %% in this case leave out:
            %% after 0 -> ok

            one that wrote more date than the reader read out so the
            sender got suspended, and then the reader closed the
            socket. (Reported and diagnosed by Alexey Shchepin.)</p>

            meant to replace tuple funs <c>{M,F}</c> which have many
            problems.</p>
          <p>The new type test <c>is_function(Fun,A)</c> (which may be
            used in guards) test whether <c>Fun</c> is a fun that can be
            applied with <c>A</c> arguments. (Currently, <c>Fun</c> can
            also be a tuple fun.)</p>

          <p>According to the documentation <c>global</c> implements
            the equivalent of <c>register/2</c>, which returns
            <c>badarg</c> if a process is already registered. As it
            turns out there is no check in <c>global</c> if a process is
            registered under more than one name. If some process is
            accidentally or by design given several names, it is
            possible that the name registry becomes inconsistent due
            to the way the resolve function is called when name
            clashes are discovered (see <c>register_name/3</c> in
            <c>global(3)</c>).</p>
          <p>In OTP R11B <c>global</c> will not allow the registration of
            a process under more than one name. To help finding code
            where <c>no</c> will be returned, a Kernel application
            variable, <c>global_multi_name_action</c>, is hereby
            introduced. Depending on its value (<c>info</c>,
            <c>warning</c>, or <c>error</c>), messages are sent to
            the error logger when <c>global</c> discovers that some
            process is given more than one name. The variable only
            affects the node where it is defined.</p>

            reserved for copying text (what Ctrl-Ins was used for
            previously). Ctrl-Break should be used for break handling.
            Lastly, the documentation of the system flags has been

            compatibility in STDLIB 1.13.1. The flag to be used for
            this is now called <c>async_shell_start</c> and has
            been documented. New shells started from the JCL menu are
            not synchronized with <c>init</c> anymore. This makes it
            possible to start a new shell (e.g. for debugging purposes)
            even if the initial shell has not come up.</p>
