The developers of the Tor Browser (or The Tor Network) released the update to version 7.5.4 on May 9, 2018. Here is an overview of what has changed.
What is Tor?
Tor is a software package designed to make communication on the Internet anonymous and protect those involved. The data is sent via a distributed network of Tor relays operated by volunteers around the world. This is to prevent third parties from recognizing from the Internet connection which websites a user visits and where the user’s physical location is (e.g. to block websites).
Included is the Tor Browser (Firefox-based), which communicates over the Tor network and is available for Microsoft Windows, Apple MacOS or GNU/Linux. Tor is portable, so you can use its features without installing any software. Tor can run from a USB flash drive, for example, and comes with a preconfigured web browser to protect anonymity. The whole package is self-contained (portable).
