What's new in this version:

Improvements:
- Improved user guidance when starting Little Snitch for the first time. Instructions how to enable the Network Extension are now illustrated
- Added support for Private Relay connections on macOS Monterey. Since the Internet address of a Private Relay connection is not known, Little Snitch now shows it as “Private Relay”
- When recording traffic of a process via littlesnitch capture-traffic from the command line, traffic from related helper-processes is now included as well. Parameters for the capture-traffic subcommand have been renamed to reflect this change
- Connection details in the Network Monitor inspector now reflect the displayed and selected time period
- When a temporary rule expires, Little Snitch now shows a connection alert for all related connections that are still active but no longer covered by the now expired rule. These connections can then again be allowed or denied, but until a new decision is made, the previous, temporary decision (allow or deny) remains effective
- Improved connection alert to allow the creation of “Until Quit” rules for apps that are connecting via a helper tool, when the helper is already terminated, but the parent app is still running
- Improved wording of the term “software update” in German localization
- Corrected wording in tooltips of rule buttons in Network Monitor

Fixed:
- a rare crash in the Little Snitch network extension
- a rare issue where the host name of the remote server could not be determined for unencrypted HTTP connections
- expiry handling of time based temporary rules. The expiry was delayed while the computer was in sleep mode
- a possible deadlock which occurred when a “New Network” alert should have been shown
- “Sort by Data Volume” behavior in Network Monitor. The values used for sorting did not take the displayed time period into account
- a bug where the type of traffic meters in Network Monitor was not updated in all rows when switching the sort order between Last Activity and Data Volume
- the computation of traffic rates shown in the inspector of Network Monitor. Rates may have been about 30% too low
- a bug where data volume meters did not update when sorting by data volume
- When switching the displayed time period in Network Monitor from a long to a short interval, some connections did not drop off the list, even if their last activity was outside the chosen interval. This issue has been fixed
- a possible crash of the Little Snitch application when searching rules for occurrences of a string
- an issue causing lots of warning messages regarding “deprecated use of NSObject in XPC” to be shown in the Console of macOS Monterey
- a bug causing the connection alert not to update the indication that the connecting process just terminated
- a bug causing a “location services disabled” alert message to appear twice when running Network Monitor for the first time
- an issue where starting the Little Snitch application with the Option key held down did not open the Installation Status window
- various bugs with mouse-hovering sensitive areas in the connection inspector of Network Monitor
- an issue causing the “Show in Finder” button in the connection inspector of Network Monitor to disappear when clicked
- a bug causing the Little Snitch application to hang after pasting a large number of hostnames or IP addresses in the rule editor
- Corrected a typo in the German localization of the Profile popup in the connection alert
- Corrected some layout and appearance issues in the “Welcome to Little Snitch” window
