	    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>

	    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>

	    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>
	    If a timetrap timeout occured during execution of of a
	    function in a lib module (i.e. a function called directly
	    or indirectly from a test case), the Suite argument in
	    the end_tc/3 framework callback function would not
	    correctly contain the name of the test suite, but the lib
	    module. (This would only happen if the lib module was
	    compiled with ct.hrl included). This error has been
	    solved.</p>

	    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>

	    Add a proplist() type</p>
          <p>
	    Recently I was adding specs to an API and found that
	    there is no canonical proplist() type defined. (Thanks to
	    Ryan Zezeski)</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
	    cases.</p>

	    The test index page was not refreshed at the start of
	    each test suite which made it impossible to follow test
	    execution by means of refreshing the browser window (no
	    links to follow). This has been fixed.</p>

	    If a test suite would start with a test case group
	    defined without the init_per_group/2 and end_per_group/2
	    function, init_per_suite/1 would not execute initially
	    and logging of the test run would fail. This error has
	    been fixed.</p>

	    The dir and suite start option can now be used in
	    combination. E.g. executing my_SUITE in directory
	    my_tests can either be specified as "ct_run -suite
	    my_tests/my_SUITE" or as "ct_run -dir my_tests -suite
	    my_SUITE". Furthermore, the specification:
	    ct:run_test([{suite,["./my_SUITE"]},{testcase,t1}]) is
	    now interpreted as
	    ct:run_test([{suite,"./my_SUITE"},{testcase,t1}]), i.e.
	    only testcase t1 in test suite my_SUITE - not all cases -
	    will be executed.</p>

	    A new option, 'logopts', has been introduced, to make it
	    possible to modify some aspects of the logging behaviour
	    in Common Test (or Test Server). For example, whenever an
	    io printout is made, test_server adds newline (\n) to the
	    end of the output string. This may not always be a
	    preferred action and can therefore be disabled by means
	    of "ct_run ... -logopts no_nl" (or ct:run_test([...,
	    {logopts,[no_nl]}])). A new framework callback function,
	    get_logopts/0, has been introduced (see the ct_framework
	    module for details).</p>

	    A new option, 'logopts', has been introduced, to make it
	    possible to modify some aspects of the logging behaviour
	    in Common Test (or Test Server). For example, if the html
	    version of the test suite source code should not be
	    generated during the test run (and consequently be
	    unavailable in the log file system), the feature may be
	    disabled by means of "ct_run ... -logopts no_src" (or
	    ct:run_test([..., {logopts,[no_src]}])). A new framework
	    callback function, get_logopts/0, has been introduced
	    (see the ct_framework module for details).</p>

	    CT Hooks can now be assigned a priority. The priority of
	    a CTH determines when it should execute in relation to
	    other CTHs. The CTH with the lowest priority will be
	    executed first, CTHs with equal priority will be executed
	    in the order which they were installed.</p>

	    It is now possible to use a tuple {M,F,A}, or a fun, as
	    timetrap specification in the suite info function or test
	    case info functions. The function must return a valid
	    timeout value, as documented in the common_test man page
	    and in the User's Guide.</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>

	    It is now possible for the user to provide specific
	    callback modules that handle test configuration data, so
	    that data on arbitray form can be accessed (e.g. by
	    reading files or by communicating with a configuration
	    server process). Two default callback modules have been
	    introduced in Common Test: ct_config_plain and
	    ct_config_xml. The former is used to handle the
	    traditional Common Test configuration files (with terms
	    on key-value tuple form) and the latter to handle
	    configuration data on XML representation.</p>

	    been loaded on the test node in advance (e.g. sent as

	    requirement is that the no_auto_compile (or
	    {auto_compile,false}) parameter has been set.</p>

	    (with abort_current_testcase/1), or after a timetrap
	    timeout. Under these circumstances the return value of
	    end_per_testcase is completely ignored. Therefore the
	    function will not be able to change the reason for test
	    case termination by returning {fail,Reason}, nor will it
	    be able to save data with {save_config,Data}.</p>

	    has been introduced to enable Common Test Master to
	    perform host login and node startup operations over ssh.</p>

	    Previously, a repeat property of a test case group
	    specified the number of times the group should be
	    repeated after the main test run. I.e. {repeat,N} would
	    case the group to execute 1+N times. To be consistent
	    with the behaviour of the run_test repeat option, this
	    has been changed. N now specifies the absolute number of
	    executions instead.</p>

	    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

            Because a telnet connection was always identified by a

            (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>

	    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>

	    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>
