## What Jamie wrote

I have wanted to use Little Snitch for years, but it’s complexity has kept me away as well as the fact that it was a kernel extension and I worried about stability of my machine. This new version is entirely in user space, and looks like it will finally be a version that I can go with. 

> The main focus in the development of Little Snitch 5 was on the integration of the new network filter technologies introduced by Apple in macOS Big Sur. The underlying filter engine was re-built from ground up to replace the previous kernel extension based approach which is no longer supported by macOS.

I'll be getting this when I move to Big Sur.
