Today, a new set of sanctioned content was published on the Paizo blog. Replacing what appears to be a temporary home on the Organized Play Foundation website, this blog is in a slightly different format and covers material in five hardcovers so far. (An adventure, the Fall of Plaguestone, is covered via its sanctioning document.)
The new format consolidates new and previously existing rules on material ownership, rarity, character origin, and religion. The format also includes what in Pathfinder 1 would have been considered a Campaign Clarification.
The blog post may be the acting Additional Resources document for some time, so we recommend keeping it in some fashion (bookmark or otherwise) as a reference.
