My French is not that good, I can't make up from Google's translation if their source is a beta program manager or just a beta tester.
It does say however that lapytsh itself doesn't know what to think of the message, so they're not to sure about the source themselves i guess.
I guess we'll find out within 24/48 hours anyway
