I've not seen a 5.1 PDF yet, and usually, I get them before they go to DTRPG.
I haven't, either, and I keep reminding Marc to circle back around and FIX THE ERRATA. I'll make a note to actually ask Marc how MUCH of the errata he has done. It occurs to me that he may have actually worked on the list when I wasn't looking. Hey, it could happen. Some of it is easy.
And I can hear Don's keyboard clacking in my brain, typing out NO DATES! At least Marc has taken Don's advice.
