Did DxO just changed it's luminosity mask policy?

Umm, you have already commented on this, in response to @Rob’s post here:

In my trial version of PL7 the option for luminosity mask is inactive and the hover over says it’s only available in FP7 or higher. In other words, this advert is misleading, which (as I said in that other topic) is why I have reported this to the UK Advertising Standards Authority.
