	    A new option to erlang:system_monitor,
	    {long_schedule,Millis} allows you to monitor if your
	    system performs any lengthy NIF, BIF or driver operations
	    that might result in bad resource utilization and
	    therefore bad performance. To better test this
	    functionality, the test_server has been updated to
	    include configure tests for usleep.</p>

	    test_server_h will now recognize info_reports written by
	    ct connection handlers (according to the description in
	    cth_conn_log) and ignore them as they will be completely
	    handled by by ct_conn_log_h.</p>
          <p>
	    Earlier test_server_h would print a tag (testcase name)
	    before forwarding the report to error_logger_tty_h. This
	    would cause lots of tags in the log with no info report
	    following (since error_logger_tty_h did not handle them).</p>

	    It is now possible to sort the HTML tables by clicking on
	    the header elements. In order to reset a sorted table,
	    the browser window should simply be refreshed. This
	    feature requires that the browser supports javascript,
	    and has javascript execution enabled. If the 'ct_run
	    -basic_html' flag is used, no javascript code is included
	    in the generated HTML code.</p>

	    Verbosity levels for log printouts has been added. This
	    makes it possible to specify preferred verbosity for
	    different categories of log printouts, as well as general
	    printouts (such as standard IO), to allow control over
	    which strings get printed and which get ignored. New
	    versions of the Common Test logging functions, ct:log,
	    ct:pal and ct:print, have been introduced, with a new
	    Importance argument added. The Importance value is
	    compared to the verbosity level at runtime. More
	    information can be found in the chapter about Logging in
	    the Common Test User's Guide.</p>

	    The Erlang/OTP test runner ts has been extended to allow
	    cross compilation of test suites. To cross compile the
	    test suites first follow the normal cross compilation
	    procedures and release the tests on the build host. Then
	    install ts using an xcomp specification file and compile
	    test suites using ts:compile_testcases/0. For more
	    details see $ERL_TOP/xcomp/README.md.</p>

	    After a test case timeout or abortion, the
	    end_per_testcase function executes on a new dedicated
	    process. The group leader for this process should be set
	    to the IO server for the test case, which was not done
	    properly. The result of this error was that no warnings
	    about end_per_testcase failing or timing out were ever
	    printed in the test case log. Also, help functions such
	    as e.g. test_server:stop_node/1, attempting to
	    synchronize with the IO server, would hang. The fault has
	    been corrected.</p>

	    Test Server and Common Test would add new error handlers

	    A new optional feature has been introduced that enables
	    Common Test to generate priv_dir directory names that are
	    unique for each test case or config function. The name of
	    the option/flag is 'create_priv_dir' and it can be set to
	    value 'auto_per_run' (which is the default, existing,
	    behaviour), or 'auto_per_tc' or 'manual_per_tc'. If
	    'auto_per_tc' is used, Test Server creates a dedicated
	    priv_dir automatically for each test case (which can be
	    very expensive in case of many and/or repeated cases). If
	    'manual_per_tc' is used, the user needs to create the
	    priv_dir explicitly by calling the new function
	    ct:make_priv_dir/0.</p>

	    Common Test will now print error information (with a time
	    stamp) in the test case log file immediately when a test
	    case fails. This makes it easier to see when, in time,
	    the fault actually occured, and aid the job of locating
	    relevant trace and debug printouts in the log.</p>

	    If the optional configuration functions init_per_suite/1

	    file. Any printouts made by the pre- or
	    post_init_per_suite and pre- or post_end_per_suite hook
	    functions are saved in the log files for these functions.</p>

	    (analogue to the test suite- and test case info

	    When running tests with auto-compilation disabled, Common
	    Test could only display the test suite source code on
	    html format in the test case log if the source file was
	    located in the same directory as the pre-compiled suite.
	    This has been modified so that Common Test now tries to
	    locate the source file by means of the test suite module
	    info (Suite:module_info/1). As a result, a suite may now
	    be compiled to a different output directory (e.g.
	    $MYTEST/bin) than the source code directory (e.g.
	    $MYTEST/src), without the source-code-to-html generation

	    Alpha release of Common Test Hooks (CTH). CTHs allow the
	    users of common test to abtract out common behaviours
	    from test suites in a much more elegant and flexible way
	    than was possible before. Note that the addition of this
	    feature may introduce minor changes in the undocumented
	    behaviour of the interface inbetween common_test and
	    test_server.</p>

	    The conf case in Test Server has been extended with
	    properties that make it possible to execute test cases in
	    parallel, in sequence and in shuffled order. It is now
	    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. The properties are specified in a list
	    in the conf case definition: {conf, Properties, InitCase,
	    TestCases, EndCase}. The available properties are:
	    parallel, sequence, shuffle, repeat, repeat_until_all_ok,
	    repeat_until_any_ok, repeat_until_any_fail,
	    repeat_until_all_fail.</p>

	    Test Server is a portable test server for automated
	    application testing. The server can run test suites on
	    local or remote targets and log progress and results to
	    HTML pages. The main purpose of Test Server is to act as
	    engine inside customized test tools. A callback interface
	    for such framework applications is provided.</p>
