How to update Chia Gui?

Ok one more thing is I noticed that my xch_target_address doesn’t match anymore (thank goodness this thread helped me a bit). I was able to compare my old config.yaml file and my new config.yaml file.

What is the difference between farmer reward address and pool reward address?
Should they always be set the same? (As I am seeing them the same right now).

Back then I remember this only being one address where you receive all the rewards If I am not mistaken. I have been simultaneously self pooling and pooling at the same time, but I believe I was using the address to receive rewards.
