	    If the init_per_testcase/2 function fails, the test case
	    now gets marked and counted as auto skipped, not user
	    skipped (which would previously happen).</p>

	    The documentation is now built with open source tools
	    (xsltproc and fop) that exists on most platforms. One
	    visible change is that the frames are removed.</p>

	    For a failed test case, the tc_done event is supposed to
	    report info on the form {failed,Error}. Only Error was
	    reported, however, which has now been fixed.</p>

	    Various updates of the test events have been implemented.
	    The data field for some events, such as tc_done and
	    tc_auto_skip has been modified to make pattern matching
	    on the data easier and more consistent. Also the order in
	    which some events are received has been altered. E.g. the
	    tc_auto_skip event for a test case now comes after the
	    tc_done for the failed configuration function (not
	    before) which makes more sense. Note that no new events
	    have been added and that the event record remains
	    unchanged.</p>

	    The marquee used for test names on the all_runs.html page
	    has been removed on request. Note that the test name
	    field has the full text string in a title tag, which is
	    displayed when hovering the mouse pointer over it (i.e.
	    if the web browser supports title tags).</p>

	    It is now possible to refresh the top level index files
	    in an arbitrary log directory by specifying a
	    {refresh_logs,LogDir} tuple in the ct:run_test/1 options
	    list. Also the -refresh_logs flag for the run_test script
	    has been extended to take an optional LogDir argument,
	    i.e. -refresh_logs [LogDir]. If no LogDir is specified,
	    current working directory is assumed, unless the log
	    directory is set with the -logdir flag.</p>

	    It was previously required that test suites were located
	    under a test object (or OTP application) sub-directory
	    named "test" (or under a directory named
	    "&lt;testobject&gt;_test"). This has been changed so that
	    Common Test now looks for suites primarily in a test
	    sub-directory only if the directory exists. Otherwise it
	    will assume the suites are stored in the same directory
	    the user specifies with e.g. the 'dir' start flag/option.</p>

	    It is now possible to see if a test case has been skipped
	    explicitly or because a configuration function has
	    failed. Also, the history page (all_runs.html) now has
	    scrolling text displaying the test names. The old format
	    (showing names as a truncated string) can still be
	    generated by means of the flag/option 'basic_html'.</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
	    Guide for details.</p>

	    supported.</p>

            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>

            The step functionality in Common Test (based on
            interaction with Debugger) was broken. This has been
            fixed, and some new step features have also been added.
            Please see the Common Test User's Guide for details.</p>

            If the Erlang runtime system was started without access
            to an erlang shell (e.g. -noshell), compilation errors
            would cause a crash in the Common Test application.
            Without access to a shell, Common Test can not prompt the
            user to choose to continue or abort the test session, but
            must assume that the session should proceed.</p>

            It is now possible for the Common Test user to disable
            the auto-compile feature. This is done by specifying the

            option {auto_compile,false}.</p>

            A new function, ct:get_config/3, has been added to Common
            Test that makes it possible to - if a particular config
            variable has been defined in multiple config files -
            return all matching values for the variable. The order of
            the elements in the returned list is the same as the
            specified order of the config files.</p>

            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>

          <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>

        </item>
        <item>
          <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>

	    Common Test now uses the re application instead of the
	    previous rx driver to perform regular expression matching
	    on telnet strings. Since re works on all supported
	    operating systems, it is now possible to run telnet
	    sessions also on platforms such as e.g. Windows (which
	    was not the case with the previous rx driver). Note that
	    the rx driver is obsolete from now on, and will be
	    removed from Common Test after OTP R12B.</p>
