Bethesda have recently dropped a piece of info that the next big update for Fallout 76 is ready and it's hitting the test server this week. The information is published on their blog as well.
The update will iron out a lot of nasty bugs and It will include some quality of life changes (as expected). Bethesda also teased a return to the Monongah Mine and I'm very excited and I'm very excited about that as well.
Meanwhile, update 20 should keep us busy until the next one rolls out. I just love those seasonal gimmicks.
