macOS Big Sur 11.2.3 (build 20D91) released
Available via software update. Info from What's new in macOS Big Sur 11.2.3:
"macOS Big Sur 11.2.3 provides important security updates and is recommended for all users."
The security fix in macOS Big Sur 11.2.3 is for a malicious web content vulnerability.
(I suspect this is related to all the late February Apple forum posts on Malware.)
- If you have trouble, try updating from Safe Mode.

M1 Mini no HDMI video after macOS 11.2.3 Update (fixed)
M1 Mac Mini updated to 11.2.3 OK (from 11.2.1), but on the first (automatic) reboot for login after the update, there was no HDMI video output from the M1 Mini. Tried disconnect/reconnecting the HDMI cable, power cycling the Display (Samsung HM2493 1920x1200/60hz) - didn't help. Held the Mini's power button down (forcing a shutdown), then powered on and it booted up OK with HDMI working. (As noted earlier, this M1 mini has no 3rd party software/drivers installed and no migration from a previous Mac/OS. M1 Mac mini firmware is still v6723.81.1, no change since macOS 11.2 update.)

CVM Server Crashes still not fixed in Big Sur 11.2.3
Despite reporting it to Apple twice (with 11.2 and 11.2.1), macOS 11.2.3 does not fix the CVM Server crash with DVD Playback first seen with macOS 11.2. (Other M1 Mac users have also reported repeated CVM Server crashes since macOS 11.2 update. Often forcing a restart.)

Safari 14.0.3 (new builds), iOS 14.4.1, iPadOS 14.4.1, watchOS 7.3.2 (Security Fixes)
(All include security fix related to malicious web content.)
Safari Technology Preview 122
See the release notes for a complete list of improvements & bug fixes.

The Firefox 86.0.1 release notes lists bug fixes including "Fixed an issue on Apple Silicon machines that caused Firefox to be unresponsive after system sleep".
