Objective Development (Hacker News):
Third party developers can now bundle their apps with an Internet Access Policy file containing descriptions of all network connections that are possibly triggered by their app. Little Snitch will then display that information to users, helping them in their decision how to handle a particular connection. A description of the policy file format will be provided soon.

This results in much more precise filter matching, especially in those cases where one and the same IP address is possibly associated with multiple hostnames (e.g. google.com vs. googleanalytics.com)

Jun 28, 2017 Objective Development Software GmbH has released the public beta of Little Snitch 4. Welcome to the Public Beta of Little Snitch 4. We are very excited to.

To avoid a vast numbers of connection alerts from appearing when using common macOS and iCloud services, Little Snitch now provides preconfigured rulesets for these usage areas.
Sounds awesome. It is compatible with macOS 10.13 if you use the new option in System Preferences to allow the kernel extension to load. Previously, kernel extensions just had to be signed using a special key that you apply for. Going forward, Apple is deprecating kernel extensions, so hopefully they will be adding an extension point so that utilities like Little Snitch can continue to work. If you want to do novel things with the kernel that Apple hasn’t pre-planned for, it sounds like you’ll be out of luck.

They are deprecating Kernel Extensions on iOS. But macOS is clearly the next step. They are looking for feedback on what is currently missing in the Network Extension features set so that moving from NKE to NE can be done.
