The second "release candidate" version of macOS Big Sur 11.2 is now available to developers and beta users. This comes after Apple released the first version of the MacOS Big Sur 11.2 RC last week. The update offers M1 Mac enhancements, Bluetooth fixes and more.
Apple has moved away from the previous "golden master" name for near-final beta releases. Instead, in the future, the company will use the term "Release Candidate" or RC, to refer to an almost final beta version.

We expect macOS Big Sur 11.2 to release to the public this week. Today's update to the second release release candidate probably includes some minor ones corrections and improvements of last minute. The information is available under construction number 20D62, compared to last week's RC version number 20D53.
Here are Apple's release notes for macOS Big Sur 11.2:
MacOS Big Sur 11.2 fixes the following issues:
- External monitors may display a black screen when connected to a Mac mini (M1, 2020) using an inverter HDMI in DVI
- Changes to Apple ProRAW photos in the Photos application may not stored
- The iCloud Drive could be turned off after deactivation of the iCloud Drive Desktop & Documents Folders option
- System Preferences may not be unlocked when you enter your password administrator
