This one discusses compatibility of hardware and software with Big Sur.
The second one gives a visual comparison of Big Sur to Catalina.
Both are interesting to those of us who may not be running beta versions of osMac 11 (also known as 10.16) and it seems as if the first list will be updated as things progress.
On a Mac since 1984. Currently: 24" M1 iMac, M2 Pro Mac mini with 27" BenQ monitor, M2 Macbook Air, MacOS 14.x; iPhones, iPods (yes, still) and iPads.
