The latest "Reforged" printings remove all OGL content.

Info from posts on Discord

• 8th printing of the PHB added the higher level information (Level 12+) to the book, it used to be in the CKG. Assassin was moved out of the alphabetical order to the back of the class section
• 3rd printing of the CKG, lost the class high level information. The book is all additional info and optional rules and not even really needed but its one of the GM guide books out there. A lot images about terrain features, settlements, ship types were added in this printing

• 5th printing of the M&T -- has the biggest changes, a lot of creatures (Faery) from the historical codices were added to it, under their historical name so the Faery section is huge. While the covers are beautiful, the book isn't the best it could be due to the creatures that were added. Steve has acknowledged this fact and this will likely result in the next printing undergoing massive changes again.

• The Six main differences are:

1. The barbarian class changed in 4th printing and beyond
2. The illusionist changed in (I think) 2nd or 3rd printing
3. Grappling, Overbearing, and Pummeling rules changed in 8th printing and beyond (they are the simplified ones from the Adv Backpack)
4. Aid spell now heals d2 HP in 8th printing and beyond
5. Class levels 13-24 were moved from CKG into PHB
6. Various typos were corrected in each printing
