macOS Big Sur 11.2 What’s New
macOS Big Sur 11.2 improves Bluetooth reliability and fixes:

A black screen is displayed when external displays are connected to the Mac mini (M1, 2020) using an HDMI to DVI adapter
Not saving edits to Apple ProRAW photos in Photos app
iCloud Drive is turned off after iCloud Drive Desktop and Documents Folder option is disabled
Unlocking in System Preferences when you enter your administrator password
Emoji & Symbols pane not displayed when pressing the World key
Although not mentioned in the release notes, one of the Big Sur‌ 11.2 betas removed a feature that allowed Apple apps to bypass third-party firewalls, security tools, and VPN apps. The operating system included a ContentFilterExclusionList that allowed Apple’s apps like the App Store, Maps, iCloud, and more to avoid user-installed firewall and VPN apps. Apple apps will now be compatible with VPN apps and will no longer be able to bypass firewalls and other security tools.

You can perform the update immediately from the Software Update option in the macOS System Preferences application.
