Sorceror having Diplomacy update

[Brokentooth]

Hello, in another thread someone posted this:

""...(and PF Sorcerors now have Diplomacy as Class Skill)..""

Could someone please point me to where I can find this update?

I'd just like to be able to see this and to look if there's also other errata that I've missed and should update for my character.

Thank you!

Hmm, strange. The only Sorcerer I see with Diplomacy as a class skill is the Infernal Bloodline Sorcerer...

I don't know, either. Maybe this source made a mistake?
