+	    The test result when a hook function fails is in general
+	    the same as if the function that the hook is associated
+	    with fails. For example, if <c>post_init_per_testcase</c>
+	    fails the result is that the test case is skipped, as is
+	    the case when <c>init_per_testcase</c> fails.This,
+	    however, was earlier not true for timetrap timeouts or
+	    other error situations where the process running the hook
+	    function was killed. This is now corrected, so the error
+	    handling should be the same no matter how the hook
+	    function fails.</p>

+	    In some rare cases, when two common_test nodes used the
+	    same log directory, a timing problem could occur which
+	    caused common_test to crash because it's log cache file
+	    was unexpectedly empty. This is now corrected.</p>

+          <p>
+	    <c>post_groups/2</c>, which is called after
+	    <c>Suite:groups/0</c><br/> <c>post_all/3</c>, which is

+	    These functions allow modifying the return values from

+	    respectively.</p>
+          <p>
+	    A new term, <c>{testcase,TestCase,RepeatProperties}</c>
+	    is now also allowed in the return from <c>all/0</c>. This

+	    number of times, or until it fails or succeeds once.</p>
