What's new in this version:

General Improvements:
- Improved TouchBar support
- Improved handling of FTP connections
- Improved upgrade from version 3 to preserve an active Silent Deny Mode
- Domains and search-domains that are explicitly configured in macOS System Preferences > Network Preferences > Advanced > DNS are now considered
- Fixed some spelling errors, improved wording and localization
- Fixed a crash of Little Snitch Agent when turning off the Network Monitor while Silent Mode was active
- Fixed an issue when creating a new rule or profile in Little Snitch Configuration while the Known Networks window was open
- Fixed a possible kernel panic
- Many minor bug fixes

Connection Alert:
- 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

Menu-Bar Icon:
- Improved indication of active silent mode in menu bar
- 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

Network Monitor:
- Added preferences option to show the Network Monitor when the mouse hovers the menu bar icon
- Added “Help” menu item
- Improved Top Countries summary statistics in Connection Inspector
- Fixed a bug where Network Monitor became unresponsive when Little Snitch Daemon crashed
- Fixed an issue causing Network Monitor to start with an empty list instead of showing the stored previous connections
