The connection alert now shows a warning when the connecting application is affected by Gatekeeper Path Randomization (which indicates that the app was not correctly installed).
The alert now also shows a plain text representation of internationalized domain names containing special characters which require encoding. This makes it possible to identify homograph domain name attacks.
It’s now possible to get the port and protocol specific option preselected in the connection alert (See Little Snitch Configuration > Preferences > Alert).
The connection alert now allows to create rules for an entire Content Delivery Network domain.
Fixed the ordering of minimized alerts: When maximizing the alert, the last minimized alert is opened first.

The menu bar icon is now always shown while “Silent Mode — Deny Connections” is active, regardless of the “Show status in menu bar” preference option.

Added “Help” menu item.
Improved Top Countries summary statistics in Connection Inspector.

Little Snitch 4.0 Public Beta 1 (5068)
Compatibility with macOS High Sierra
This version is compatible with the beta version of macOS High Sierra 10.13.
During the Installation of Little Snitch on macOS High Sierra you may see a message: “System Extension Blocked”. This is a new security mechanism in High Sierra, requiring you to explicitly allow the installation of a third party system extension. To complete the installation of Little Snitch you have to allow loading the extension in System Preferences > Security & Privacy > General.
There’s a known issue in the map view of Network Monitor causing connection endpoints to be shown twice.
Network Monitor
Fixed a possible crash when zooming to a particular map region in the course of clicking a connection in the list.
Added further time interval filter options for showing only connections from the last week or the last 30 days.
The properties shown in the Summary Inspector (denied, unconfirmed, incoming) now correctly correlate to the corresponding filter options.
Improved pinch-zooming in map: The zooming no longer stops when clusters are expanded into their sites.
Updated GeoIP database. Network Monitor should now know more locations for IP addresses.

Little Snitch 4.0 Private Beta 4 (5066)
Network Monitor
A status line below the connection list now indicates when only a selection of connections is currently displayed, and it provides a quick way to clear that selection.
Little Snitch Configuration
The rule editor now warns if an IP address is entered although the input of a host or domain name is expected.
Automatic software update checks are now always enabled in beta versions.
Other Bug Fixes and Improvements
Fixed a possible odd behavior if a rule refers to many IP address ranges or host names.

Little Snitch 4.0 Private Beta 3 (5064)
Network Monitor
Fixed a possible crash of Network Monitor when selected connections span a broad geographic region on the map.
Appearance changes (light/dark) are now applied to all windows.
The context menu now also works for a multiple selection of connections.
The connection context menu now contains rule editing options. Pressing the Option key allows to create a rule in the current profile.
Improved undo description for undo/redo of rule manipulation operations.
Little Snitch Configuration
Fixed: When editing a multiple selection, code signature requirements are no longer removed from edited rules.
First Impression
Fixed a possible crash of the initial Welcome Window. This crash could prevent Little Snitch Configuration from starting altogether.
The Network Monitor demo period has been reset to give users upgrading from Little Snitch 3 a chance to try the new version for another month.
If the Network Monitor demo period has expired and the user turns on Silent Mode, we now show an appropriate message, but no longer ask for starting Network Monitor.
Other Bug Fixes and Improvements
After confirming a Connection Alert the keyboard focus is now given back to the previous application. This is the traditional behavior, but was broken due to code refactoring.
Fixed a crash of Little Snitch Helper when stepping through the connection list in Network Monitor, which triggered lots of code signature checks if the “Code Signature” section was open in the Inspector pane.
Improved handling of code signature requirements for Apple processes.
UI graphics and animation improvements.
Other minor bug fixes.

Little Snitch 4.0 Private Beta 2 (5062)
Network Monitor
The rule management buttons now always indicate the existence of matching rules. If there’s an exact match for this kind of connections, the buttons are red or green. Otherwise, if the rule matches a subset or superset of connections, the match is indicated in gray.
The search field has been moved to the top of the window and it now contains a filter menu providing access to various filter options.
Removed menu button from the window toolbar. The options contained in this menu are now accessible from the main menu and from the filter menu in the search field.
Significantly improved performance when opening the Network Monitor window.
“Show Corresponding Rules” in context menu should now work in all cases, no longer reporting that the corresponding rules don’t exist anymore.

The map now automatically zooms to the connections that are selected in the list.
Welcome Window
The initial Welcome Window (which is shown automatically after the first installation) is now kept on top of other windows.
Connection Alerts that occur while the initial Welcome Window is shown are now minimized so they don’t interfere with the initial setup.
General
Fixed a bug where connections from VirtualBox guest were shown with IP address only.
Fixed some layout issues on OS X 10.11.
Fixed an issue with Connection Alerts for Java applications. The alert always complained about code signature issues.
Fixed a bug which prevented some web sites from loading when deny-rules blocked some content.
