+ Common Test adds the test suite directories to the code
+ path before executing the tests. These directories should
+ also be removed from the code path at the end of the test
+ run, which, prior to this fix, was not performed.</p>

+ An entry is now created in the index.html file (i.e. the
+ overview file for the test run) for each repeated test
+ during a test run. This was previously not the case. Note
+ that in the top level (logdir) index file, however, only
+ the last test result is listed. For example, given the
+ test spec:
+ [{merge_tests,false},{dirs,"test1"},{dirs,"test1"}]. In
+ the index file for the test run (under
+ Logdir/ct_run.Node.Date.Time), both tests are listed. In
+ the top level index file (under Logdir), only the last
+ test is listed (one has to find the previous results
+ through the all_runs.html file).</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>

+ The ct:get_status/0 function would cause the calling
+ process to receive 'DOWN' messages if no tests were

+ Two or more test cases executing in parallel and printing

+ Test Server and Common Test would add new error handlers

+ When starting a test with ct_run and adding a directory
+ to the code path using -pa or -pz (preceding -erl_args),
+ Common Test would delete any existing directory in the
+ code path with the same base name (see
+ filename:basename/1) as the directory being added. This

+ <p>
+ 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>
+ <p>
+ Own Id: OTP-9659 Aux Id: seq11930 </p>

+ A column for test case group name has been added to the
+ suite overview HTML log file.</p>
+ <p>
+ Own Id: OTP-9730 Aux Id: seq11952 </p>
+ </item>
+ <item>
+ <p>
+ It is now possible to use the post_end_per_testcase CT
+ hook function to print a comment for a test case in the
+ overview log file, even if the test case gets killed by a
+ timetrap or unknown exit signal, or if the
+ end_per_testcase function times out.</p>
+ <p>
+ Own Id: OTP-9855 Aux Id: seq11979 </p>
+ </item>
+ <item>
+ <p>
+ The pre- and post CT hook functions are now always called
+ for all configuration functions, even for configuration
+ functions that are not implemented in the test suite.</p>
+ <p>
+ Own Id: OTP-9880 Aux Id: seq11993 </p>
+ </item>
+ <item>
+ <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>
+ <p>
+ Own Id: OTP-9904 Aux Id: seq11985, OTP-9900 </p>
+ </item>
+ <item>
+ <p>
+ Test Server has been modified to check the SASL
+ errlog_type parameter when receiving an error logger
+ event, so that it doesn't print reports of type that the
+ user has disabled.</p>
+ <p>
+ Own Id: OTP-9955 Aux Id: seq12013 </p>
+ </item>
+ <item>
+ <p>
+ The test specification term 'skip_groups' was implemented
+ in Common Test v1.6. It was never documented however,
+ which has now been attended to. Please see the Test
+ Specifications chapter in the User's Guide for
+ information.</p>
+ <p>
+ Own Id: OTP-9972</p>
+ </item>
+ <item>
+ <p>
+ The Common Test Master has been updated to use a CSS
+ style sheet for the html log files.</p>
+ <p>
+ Own Id: OTP-9973</p>
+ </item>
+ <item>
+ <p>
+ If the init_per_group/2 and end_per_group/2 functions are
+ not implemented in the test suite, Common Test calls it's
+ own local init- and end functions - previously named
+ ct_init_per_group/2 and ct_end_per_group/2 - when a group
+ is executed. These functions have been renamed
+ init_per_group/2 and end_per_group/2 respectively. Note
+ that this may affect any user event handler identifying
+ events by the old names.</p>

+ </item>
+ <item>
+ <p>
+ By specifying a user defined function ({M,F,A} or fun) as
+ timetrap value, either by means of an info function or by
+ calling ct:timetrap/1, it is now possible to set a
+ timetrap that will be triggered when the user function
+ returns.</p>
+ <p>
+ Own Id: OTP-9988 Aux Id: OTP-9501, seq11894 </p>
+ </item>
+ <item>
+ <p>
+ If the optional configuration functions init_per_suite/1
+ and end_per_suite/1 are not implemented in the test
+ suite, local Common Test versions of these functions are
+ called instead, and will be displayed in the overview log
+ 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>
+ <p>
+ Own Id: OTP-9992</p>
+ </item>
+ <item>
+ <p>
+ A hook has been added to common test which outputs
+ surefire XML for usage together with CI tools such as
+ Jenkins. To enable the hook pass '-ct_hooks cth_surefire'
+ to ct_run. See the CTH documentation for more details.</p>
