There has been an update to the free PDF D&D Next rules. Looking at the file names, only the DM volume changed with version 2, but someone wrote that there were changes in the player’s volume even though the version stayed at 2.
With the DMG coming out soon, perhaps there will be a version 3 soon.
There was lots of posting about this the last week of October. I downloaded the new PDF(s), but have not had a chance to look at them.
I plan to mine them for ideas, not sure I’ll play or not.
