3.20 Betrayal Changes - Listed Where?

I know there were some changes to the Syndicate in 3.20, but going back through the patch notes and manifestos, I can't seem to find them. Can someone link me to an official source with the list of changes?

Bonus: Does anyone have an updated *uncolored* Syndicate template with the new changes I can download (and color in with my own preferences)?

I would also like to know where the new betrayal info is

I did not see any Betrayal changes listed, are you sure that there have been any?

I can't remember hearing about any changes to Betrayal, apart from some minor ones relating to unique jewel rewards.
