After macOS Big Sur was officially launched, 11.1 Beta 1 was also announced today. The Big Sur 11.1 Beta version is 20C5048k. Since Big Sur was only launched soon, I believe that some issues are still being collected for processing at this stage. As you can see from the version ending code k, this is definitely a mid-term update and will not be launched so soon.
Generally speaking, macOS will fix the problem through supplementary updates first, and then release minor updates (such as 11.0.2 , 11.0.3 ). It is estimated that before the launch of macOS Big Sur 11.1 , Apple will release several small updates.
