    <section><title>Improvements and New Features</title>
      <list>
        <item>
          <p>
	    A Getting Started chapter has been added to the Common
	    Test User's Guide.</p>

	    The test case group info function has been implemented in
	    Common Test. Before execution of a test case group, a
	    call is now made to <c>TestSuite:group(GroupName)</c>.
	    The function returns a list of test properties, e.g. to
	    specify timetrap values, require configuration data, etc
	    (analogue to the test suite- and test case info
	    function). The scope of the properties set by
	    <c>group(GroupName)</c> is all test cases and sub-groups
	    of group <c>GroupName</c>.</p>

          <p>
	    Common Test hooks are now in a final supported version.
	    The Common Test hooks allow you to abstract out
	    initialization behaviour that is common to multiple test
	    suites into one place and also extend the behaviour of a
	    suite without changing the suite itself. For more
	    information see the Common Test user's guide.</p>
          <p>
	    Own Id: OTP-9449</p>
        </item>
        <item>
          <p>
	    A new built-in common test hook has been added which
	    captures error_logger and SASL event and prints them in
	    the testcase log. To disable this (and any other built-in
	    hooks) pass 'enable_builtin_hooks false' to common test.</p>
          <p>
	    Own Id: OTP-9543</p>
        </item>
        <item>
          <p>
	    Common Test now calls info functions also for the
	    <c>init/end_per_suite/1</c> and
	    <c>init/end_per_group/2</c> configuration functions.
	    These can be used e.g. to set timetraps and require
	    external configuration data relevant only for the
	    configuration functions in question (without affecting
	    properties set for groups and test cases in the suite).
	    The info function for <c>init/end_per_suite(Config)</c>
	    is <c>init/end_per_suite()</c>, and for
	    <c>init/end_per_group(GroupName,Config)</c> it's
	    <c>init/end_per_group(GroupName)</c>. Info functions can
	    not be used with <c>init/end_per_testcase(TestCase,
	    Config)</c>, since these configuration functions execute
	    on the test case process and will use the same properties
	    as the test case (i.e. properties set by the test case
	    info function, <c>TestCase()</c>).</p>
          <p>
	    Own Id: OTP-9569</p>
        </item>
        <item>
          <p>
	    It's now possible to read the full name of the test case
	    log file during execution. One way to do this is to
	    lookup it up as value of the key <c>tc_logfile</c> in the
	    test case <c>Config</c> list (which means it can also be
	    read by a pre- or post Common Test hook function). The
	    data is also sent with the event
	    <c>#event{name=tc_logfile,data={{Suite,Func},LogFileName}}</c>,
	    and can be read by any installed event handler.</p>

        <item>
          <p>
	    The look of the HTML log files generated by Common Test
	    and Test Server has been improved (and made easier to
	    customize) by means of a CSS file.</p>
          <p>
	    Own Id: OTP-9706</p>
        </item>
        <item>
          <p>
	    Functions ct:fail(Format, Args) and ct:comment(Format,
	    Args) have been added in order to make printouts of
	    formatted error and comment strings easier (no need for
	    the user to call io_lib:format/2 explicitly).</p>
          <p>
	    Own Id: OTP-9709 Aux Id: seq11951 </p>
        </item>
        <item>
          <p>
	    The order in which ct hooks are executed for cleanup
	    hooks (i.e. *_end_per_* hooks) has been reversed.</p>
          <p>
	    *** POTENTIAL INCOMPATIBILITY ***</p>
          <p>

        </item>
        <item>
          <p>
	    Printouts to stdout may be captured during test case
	    execution. This is useful in order to e.g. read and parse
	    tty printouts from the SUT during test case execution (if
	    necessary, say, to determine the outcome of the test).
	    The capturing session is started with
	    <c>ct:capture_start/0</c>, and stopped with
	    <c>ct:capture_stop/0</c>. The list of buffered strings is
	    read and purged with <c>ct:capture_get/0/1</c>. It's
	    possible to filter out printouts made with
	    <c>ct:log/2/3</c> and <c>ct:pal/2/3</c> from the captured
	    list of strings. This is done by calling
	    <c>capture_get/1</c> with a list of log categories to
	    exclude.</p>
          <p>
	    Own Id: OTP-9775</p>
        </item>
        <item>
          <p>
	    The syntax for specifying test case groups in the all/0
	    list has been extended to include execution properties
	    for both groups and sub-groups. The properties specified
	    in all/0 for a group overrides the properties specified
	    in the group declaration (in groups/0). The main purpose
	    of this extension is to make it possible to run the same
	    set of tests, but with different properties, without
	    having to declare copies of the group in question. Also,
	    the same syntax may be used in test specifications in
	    order to change properties of groups at the time of
	    execution, without having to edit the test suite. Please
	    see the User's Guide for details and examples.</p>

	    An error in how comments are colored in the test suite
	    overview html log file has been corrected. As result, a
	    new framework callback function, format_comment/1, has
	    been introduced.</p>

	    Automatically generated init- and end-configuration
	    functions for test case groups caused incorrect execution
	    order of test cases. This has been corrected.</p>
          <p>
	    Own Id: OTP-9369</p>
        </item>
        <item>
          <p>
	    If multiple directories were specified with the 'logdir'
	    flag/option, Common Test would crash. This has been fixed
	    so that an error is properly reported instead.</p>
          <p>
	    Own Id: OTP-9370</p>
        </item>
        <item>
          <p>
	    If ct:log/2 was called with bad arguments, this could
	    cause the Common Test IO handling process to crash. This
	    fault has been corrected.</p>
          <p>
	    Own Id: OTP-9371 Aux Id: OTP-8933 </p>
        </item>
        <item>
          <p>
	    A bug has been fixed that made Test Server call the
	    end_tc/3 framework function with an incorrect module name
	    as first argument.</p>
          <p>
	    Own Id: OTP-9379 Aux Id: seq11863 </p>

	    If a timetrap timeout occured during execution of of a

	    Corrections of the vts mode. It will now report errors
	    (about e.g. incorrect config files) instead of crashing
	    or hanging. Furthermore, the requirement that the test
	    directory name must have a "_test" suffix has been
	    removed. Also, a workaround has been implemented for the
	    limitation that the file browser (in many web browsers)
	    will only return the basic file name, not the full
	    directory path (which made it impossible to have config
	    files in other directories than the main test directory).</p>

	    It is now possible to use the 'step' flag/option to run
	    the debugger for test suites that contain test case
	    groups. This previously caused Common Test to crash. If
	    'step config' is specified, breakpoints are now also
	    automatically set on init_per_group and end_per_group.
	    Note that breakpoints are always set automatically on
	    test case functions and this is true also for grouped

	    The timetrap handling has been made more user
	    controllable by means of new start options and new ct
	    interface functions. With the 'multiply_timetraps' start
	    option, it's possible to specify a value which all
	    timetrap timeout values get multiplied by. This is useful
	    e.g. to extend the timetraps temporarily while running
	    cover or trace. The 'scale_timetraps' start option
	    switches on or off the Test Server timetrap scaling
	    feature (which tries to detect if the tests may benefit
	    from extended timetraps, e.g. due to running certain test
	    tools, and performs the scaling automatically).
	    Furthermore, the ct:timetrap/1 function has been
	    introduced, which makes it possible to set/reset
	    timetraps during test execution. Also, a ct:sleep/1
	    function is now available, which takes the timetrap
	    parameters into account when calculating the time to
	    suspend the process.</p>

	    The telnet client in Common Test sent [IAC,DO,NOP] to the
	    server in attempt to keep the connection alive. This is
	    not a valid sequence according to the standard, and some
	    telnet servers would terminate the connection because of
	    it. The client has been changed to send [IAC,NOP] every
	    10 secs instead, which should be a valid sequence. The
	    client does not negotiate this type of "keep alive"
	    message with the server, and if it causes problems, the
	    user may disable the keep alive feature by adding
	    {keep_alive,false} to the telnet configuration data for
	    the server/connection. Please see the ct_telnet and
	    unix_telnet manual pages for details.</p>

	    the user specifies with e.g. the 'dir' start flag/option.</p>

	    Test case groups have been introduced. With this feature
	    it's possible to execute groups (possibly nested) of test
	    cases, each group wrapped with a call to function
	    init_per_group/2 and end_per_group/2. Group definitions
	    are done by means of the new call-back function groups/0,
	    which should return a list of definitions. A group
	    definition contains a name tag, a list of properties and
	    a list of test cases (including possible nested group
	    definitions). The properties make it possible to execute
	    test cases in parallel, in sequence and in shuffled
	    order. It is also possible to repeat test cases according
	    to different criterias. The properties can be combined,
	    making it possible to e.g. repeat a conf case a certain
	    number of times and execute the test cases in different
	    (random) order every time. Available properties are:
	    parallel, sequence, shuffle, repeat, repeat_until_all_ok,
	    repeat_until_any_ok, repeat_until_any_fail and
	    repeat_until_all_fail. Please see the Common Test User's

            When running a test which includes all suites in a test
            directory, if the auto compilation would fail for one
            suite, all following suites would be excluded from the
            test. This was an unwanted behaviour and has been
            corrected. Now all suites will always be compiled and
            only the failing ones excluded from the test (and logged
            as missing).</p>

            return all matching values for the variable. The order of

            Because a telnet connection was always identified by a
            config variable alias, it was impossible to open multiple
            connections using the same telnet host data entry in the
            config file. This limitation has been removed by making
            it possible to associate a connection with handle value
            only (i.e. multiple connections may be opened using the
            same config variable). See ct_telnet:open/4 for details.</p>

            A new syntax for defining default config data values has
            been introduced. In previous versions of Common Test, to
            define and access a default value for a config variable
            (in the suite info- or test case info function), an alias
            name had to be used. With the new syntax you may define
            default values without reference to aliases, like this:
            {default_config,VarName,DefaultValue}. Please see the
            User's Guide for more info.</p>

            In previous versions of Common Test, whenever a config
            variable got associated with a name (by means of a
            require statement), the config variable name was replaced
            with the new name. This introduced unwanted dependencies
            between test cases (e.g. if one test case would introduce
            a new name, the following test cases could no longer
            access the config data by means of the original
            variable). This functionality has now been updated so
            that when new names are introduced with require, they
            become aliases (references) instead of replacements.
            Hence, config data elements can always, at any time, be
            accessed by means of the original config variable names.</p>

	    The configure test of the rx lib in Common Test was not
	    performed during the general OTP application
	    configuration phase. This made e.g. autoconf impossible.
	    This has been changed to correspond with the normal OTP
	    build procedure.</p>

          <p>
	    The rx library, included with common_test, failed to
	    build on on some architectures because the -fPIC compiler
	    option was missing.</p>
