What's new in this version:

Improved:
- The connection alert now indicates when a connection was established via iCloud Private Relay (Private Relay is a new feature of macOS Monterey, which is currently in beta)
- Improved detection of iCloud Private Relay connections on computers with IPv6 connectivity
- Updated QUIC protocol parser to support the latest IETF versions. This results in fewer connection alerts showing only the IP address of the remote server instead of its hostname when using Chrome or Firefox
- Improved rule group subscriptions to support various common block list formats, consisting of lines with domain names, IP addresses or IP networks in CIDR notation, or blocklists in /etc/hosts format
- Improved display of IP address rules. When a rule affects just a single IP address range, that range is now shown in the rule list.
- Improved performance in Network Monitor when scrolling through connections with key-repeat
- Added Internet Access Policy information for the “nehelper” process of macOS
- When the update of a subscribed rule group fails, the cause is now reported in more detail
- Automatic backup of ruleset and configuration data at regular intervals. Up to eight backups are kept. The Restore from Backup command also offers these automatic backups.
- Added missing localizations of some texts

Fixed:
- Fixed a bug where reading the code identity of of applications with large Mach headers did not work. Rules for these apps created in Little Snitch Configuration resulted in an identity mismatch alert.
- Fixed a bug where Until-Quit rules could expire even after they had been turned into permanent rules
- Fixed a bug where enabling an identity check for a process did not work
- Fixed a problem that could cause connection alerts to re-appear five seconds after allowing or denying the connection
- Fixed an issue that could cause the Little Snitch network extension to refuse starting
- Added workaround for a bug in MapKit causing the centering of the map on the current location to be off by 180 degrees longitude under rare circumstances
