Did the Cisco test engine change recently?

When I started my session, I was offered an optional practice test. The sample was similar to the two test prep tools I used. When I actuall started the test, i was given (no option) a second sample, which was a more elaborate engine, with scrolling subwindows, and other enhancements. Just curios if there is anybody who has taken the test before and again recently (either multple attempts having failed, or having to renew) that can report the engine changed or has always been as it was yesterday.
