What's new in this version:

Improvements:
- Improved accessibility via VoiceOver
- Better detection of VPNs for Automatic Profile Switching
- Improved indication of Little Snitch installation issues in the status menu icon
- Performing code signature verification for shell scripts and other scripts, if they are signed
- Shell scripts and other scripts are no longer considered as the connecting process when they use helper processes like ping or curl. They are now treated as the parent of the helper process
- Little Snitch no longer warns when shell scripts and other scripts don’t have a code signature
- Accepting code signatures of iOS applications on Apple Silicon Macs
- The macOS kernel is now treated as if it were code-signed. This allows the default localnet rules to apply to the kernel

- Numerous user interface improvements

Fixed:
