+ 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>

+ <p>
+ These functions allow modifying the return values from

+ <p>
+ A new term, <c>{testcase,TestCase,RepeatProperties}</c>
+ is now also allowed in the return from <c>all/0</c>. This
+ can be used for repeating a single test case a specific
+ number of times, or until it fails or succeeds once.</p>
