macOS 12.2.1
Some affected users saw their Mac's battery life drop from 100% to 0% while in sleep mode overnight after installing the macOS 12.2 update, with both Intel-based Macs and Apple silicon-based Macs affected. The problem stopped when Bluetooth was disabled or when Bluetooth accessories were disconnected from the Mac, which was not an ideal solution for users.
Apple addressed the problem in macOS Monterey 12.3 beta 2 yesterday, but now Mac owners will not need to wait for the macOS Monterey 12.3 launch to fix their Bluetooth battery drainage issues.
Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.
Initial testing unfortunately demonstrates that one major bug in 12.0.1, 12.1 and 12.2 hasn’t been fixed: the Finder still leaks memory badly when its Find feature is used.
I hope it fixes this bug introduced in 12.2.

Update (2022-02-11): Pieter Arntz:
Apple says it has addressed this vulnerability with improved memory management in iOS 15.3.1, iPadOS 15.3.1, macOS Monterey 12.2.1, and Safari 15.3.

The vulnerability is a use-after-free (UAF) issue in WebKit that could lead to OS crashes and code execution on compromised devices.
Update (2022-02-16): Lloyd Chambers:
Every day now, waking my 2019 Mac Pro from sleep “loses” the LG 5K Thunderbolt 3 display, sometimes 2 or 3 times a day.

But wait, there is more fun: after rebooting and logging in, the Finder desktop will not appear for 2-3 minutes, and the machine is more or less unusable. Activity Monitor shows no significant CPU, disk or network activit, so I don’t know what this POS is doing. The whole process makes it a 5-minute affair to get back to work, which has all been torn down by having to reboot.
The network/kernel_task hang is no better in macOS 12.2.1. I am now restarting my Mac twice a day to avoid it.
Update (2022-03-07): On the plus side, it seems like macOS 12.2 may have fixed the frequent lsd crashes that I had been getting. However, I’ve now seen several occurrences of a bug where I unlock the screensaver and it’s as if I was logged out—all the apps have to relaunch, with some state not restored properly.

Apps continue to silently quit in the background. (Filed three months ago as FB9781495; still ignored.)
I wonder how much of the LG 5K UltraFine hate is misplaced and should be directed at the OS instead.
