End of Life for Windows versions ≤ 8.1 and macOS versions ≤ 10.14

Users running Tor Browser on older versions of Windows and macOS will start seeing messages warning them their operating systems will no longer be supported. This is an upstream change we are inheriting from Mozilla. Starting with version 116 Firefox Windows users will require Windows 10 or later while macOS users will require macOS 10.15 or later to continue receiving Tor Browser updates. Users have until October 1st, 2024 to upgrade!

Continued Improvements on Android!

This release has removed the legacy bootstrapping functionality from Tor Browser for Android entirely. This legacy functionality depended on the tor-android-service and tor-onion-proxy-library components. With this functionality gone and replaced with the unified Tor backend living in GeckoView, we will be able to drop these components in the next release, which should result in slightly smaller .apk sizes.

We have made a few UI changes and improvements with this release. The UI which allowed users to fallback to the legacy bootstrapping process has been removed (since the backend is also gone).

Additionally various Android-specific privacy and security bugs have been fixed.

Various User Experience Improvements

On desktop, we have been working on various UI improvements and polish. The about:torconnect (aka Connect Assist) page has been restyled to better fit with Firefox's existing UI. We have also fixed various minor bugs related to letterboxing, the onion-service client-authentication dialgo, and the circuit display.
