On April 1, 2015, Intel released a new version of the Intel eXtreme Tuning Utility. The new version, v5.1.2, includes a couple of new features. First and foremost, based on the feedback from our very own El Genieben Intel improved the security of the XTU profiles. This optimization includes updating the security keys of the XTU profiles. The transition from the old to the new keys is three (3) months. From July 1, no XTU versions older than 5.1.2 can be used to make submissions.

In addition to the new security keys, Intel also included a telemetry functionality allowing to gathering information on XTU usage to improve the experience. The telemetry can always be disabled in the settings menu and is not required to be enabled for making valid submissions. Lastly, there's additional support for upcoming platforms.
