[Update] Portmaster Free 2.2.1

"Portmaster is a free and open-source privacy suite that puts you back in charge of your computer.

Features:

Monitor All Network Activity
Discover everything that is happening on your computer. Expose every connection your applications make and detect evil ones. Finally get the power to act accordingly.

Block Unwanted Connections
Many programs connect to the Internet without your knowledge. When you find unwanted connections, you can now simply block them.

Auto-Block via Selected Filter Lists
Automatically block ads, trackers and malware hosts via trusted domain-lists, which are also used by Ad-Blockers, etc. Easily change the defaults to fit your needs.

Enforce DNS-over-TLS
Even with invasive connections gone, you might not want to share your dns requests out in the open. With the Portmaster, you can easily re-route all your dns queries to a DNS-over-TLS provider of your choice.

Set Global & per-App Settings
Make your own rules. Completely cut off applications from the Internet. Or block all p2p connections except for certain apps. Or never connect to specific countries. The Portmaster has you covered."
