Official article on either AMD's or mobo makers' website. Normal stuff.The thing is you have been provided with a source you just refuse to read it . I don't know what kind of official confirmation you are waiting for ......
I'm not sure how AMD community forum works.UPDATE AGESA 0072 FOR THE UPCOMING PROCESSORS is pretty much self explanatory , you can read the same message when bios got updated to AGESA 1071 for Zen+ ( obviously it didn't say Zen + ) , it's a generic message they are not going to list you all the Zen 2 processors supported since that info is still under NDA .
The author "black_zion" is not an AMD employee, right?
Is this the only source that connects those AGESA and Zen 2? That's pretty weak.
If I posted a thread that this AGESA provides Zen 3 compatibility, would someone from AMD come to correct it?
