Little Snitch and the Deprecation of Kernel Extensions
You probably came here because your Mac showed a message telling you that software from “Objective Development Software GmbH” (Little Snitch) loaded a system extension that will no longer be compatible with a future version of macOS and that you…

How to dual-boot a Mac: Run two versions of macOS together
Want to run two operating systems on the same Mac? Here's how to dual-boot Big Sur and Monterey (or Monterey beta) so you can try out the new software.

Apple shared with developers two years ago unofficially, and then officially announced it at last year's WWDC. See the link I provided earlier in this thread.
Unfortunately, the warning will appear from time to time just as the 32-bit warnings appeared periodically in Mojave.
About system extensions and macOS - Apple Support
Some system extensions aren't compatible with current versions of macOS or won't be compatible with a future version of macOS. Learn what to do if you see an alert about system extensions or kernel extensions.

Thanks for the link!
I'm getting frustrated at Apple doing this constantly.
Just the other day on my Windows 10 gaming computer I fired up Quake 3 Arena. The binary is dated 2002. It still worked, and worked perfectly. I played an 18 year old update for a 21 year old game without issues.
Meanwhile MacOS deprecates software from only five years ago.
I wish Apple would finalize stabilize the ABI so we don't have to deal with this annoyance going forward anymore.

1. Get an external drive.
2. Get CarbonCopyCloner (or SuperDuper)
3. Use either of the above to create a bootable cloned copy of your existing OS setup.
That's really all you have to do...

I received the same notice after upgrading to 10.15.4. Simple fix, Log on to your account in Malwarebytes and make sure you have version 4, once you have version 4, go to Apple, Preferences, privacy, scroll to "Full Disk Access" check "Malwarebytes Protection". Ths information is on the Malwarebytes website.
Not sure what you are telling us. I have MWB v4, I have given it full disk access already and I got the warning about not running in future. In other words, your fix isn't a fix.
Applied the OS 10.15.4 Combo Updater to both of my Macs previously running OS 10.5.3, and have not seen any such warnings. Also, so far (knock on wood!), things are good.
Chances are high you will. There are heaps of good apps out there that currently rely on kext files to work their magic.
Applications already installed on my machine seem fine. And I use third party applications exclusively.
The alternative is the litany of Kernal Panic errors that inevitably pop up each major release, and the subsequent blame directed at Apple as a result.
One solution, rather than killing kexts completely, would be to automatically disable a kext after it causes more than two kernel panics in a short period.
This is far better than breaking software, particularly hardware drivers.
Kernel panics aren't the only issue around having software that runs at kernel level. This would provide no protection against a potentially malicious extension.
Far easier said than done when A) kexts can cause the system to fail in a way where the system can't record what failed, B) because of the lack of memory protection in kernel mode, extensions can cause other innocent extensions to fail, e.g. by overwriting their memory, C) you can't tell if the thing you're disabling is critical for system function, e.g. killing a VPN when the system is configured to require network login. Finally, D) it doesn't solve the problem of malicious kernel-mode software or bugs in kernel-mode drivers exposing security vulnerabilities, the Intel side-channel attacks being a prime example of the latter.
The Microsoft solution, which is on by default in suitably new hardware, is to wrap the entire OS into a virtual machine and only allow trusted software to run on bare metal. Called Virtualization Based Security/Hypervisor Enforced Code Integrity, it does solve some of the security issues, but it doesn't solve stability issues, you pay ~10% in performance hit, and you can't use any non-Microsoft VM software.
