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
- Improved detection of remote computer name. Connection alerts with multiple, ambiguous host names are now less likely
- Numerous user interface improvements

Fixed:
- various memory leaks in all components of Little Snitch
- a bug where the traffic view in Network Monitor did not display any data
- identity check for code signatures using non-Apple certificates
- an issue where an Identity Mismatch Alert could not be resolved by clicking “Accept Modification”
- an issue where clicking on a silent mode activity notification did not select the corresponding process in the configuration app
- a bug where loading subscribed rule groups did not load anything. This bug occurred with the abbreviated format
- a bug where subscribed rule groups were not updated automatically
- a possible crash when importing configurations from (Time Machine) backup
- a bug where Little Snitch could crash when exporting a configuration backup
