What's new in this version:

New:
- There has been quite a bit of public discussion recently about the deprecation of various types of kernel extension on macOS. Among them are Network Kernel Extensions (NKEs). You probably did not care so far, but Little Snitch 4 was based on an NKE to do its job. Since NKEs are now deprecated and no longer officially supported by Apple, we have spent the last year rewriting the core of Little Snitch to the Network Extension (NE) framework. While working on this core, we took the chance to revise some old design decisions and add some long anticipated features.

Changes:
- Compatibile with (and requires) macOS Big Sur
- Future-proof, because it is based on the new Network Extension and Endpoint Security frameworks
- Drag and Drop installation and upgrade, no reboot required
- Universal Binary which runs on both Intel and Apple Silicon Macs
- Little Snitch now comes with a command line interface for preferences editing, configuration import and export, debugging, logging and access to traffic history
- The time range available in Network Monitor’s traffic diagram has been extended from one hour to up to a year
- Rules can now specify a list of port numbers, not just one contiguous range as before
- The export format for backups is human readable normalized JSON
- Recording of network statistics is done independently of Network Monitor. You can quit Network Monitor and still have statistics recorded
- Live traffic logs via command line tool
- Ready for mass deployment installation in corporate environments
