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.
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).

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.

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.

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.

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.

A deadlock situation could occur if Common Test is forwarding error_handler printouts to Test Server at the same time a new test case is starting. This error has been fixed.

Test Server and Common Test would add new error handlers with each test run and fail to remove previously added ones. In the case of Test Server, this would only happen if SASL was not running on the test node. This has been fixed.
Own Id: OTP-9941 Aux Id: seq12009
If a test case process was terminated due to an exit signal from a linked process, Test Server failed to report the correct name of the suite and case to the framework. This has been corrected.
Own Id: OTP-9958 Aux Id: OTP-9855
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.

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.
Own Id: OTP-9855 Aux Id: seq11979
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.

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.

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.

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).
Own Id: OTP-9372 Aux Id: OTP-9396
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).

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 being affected.
Own Id: OTP-9138
It is now possible to return a tuple {fail,Reason} from init_per_testcase/2. The result is that the associated test case gets logged as failed without ever executing.

It is now possible for the Test Server framework end_tc function to change the status of the test case from ok or auto-skipped to failed by returning {fail,Reason}.
Own Id: OTP-8495 Aux Id: seq11502
Test Server will now call the end_per_testcase/2 function even if the test case has been terminated explicitly (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}.
Own Id: OTP-8500 Aux Id: seq11521
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.

The documentation is now possible to build in an open source environment after a number of bugs are fixed and some features are added in the documentation build process.
- The arity calculation is updated.
- The module prefix used in the function names for bif's are removed in the generated links so the links will look like "http://www.erlang.org/doc/man/erlang.html#append_element-2" instead of "http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".
- Enhanced the menu positioning in the html documentation when a new page is loaded.
- A number of corrections in the generation of man pages (thanks to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

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.
