The Tor Project has released Tor Browser 11.0 with a new user interface design and the removal of support for V2 onion services.
You can download the Tor Browser from the Tor Project site, and if you are an existing user, you can upgrade to the latest version by going to the Tor Menu > Help > About Tor Browser.
Tor Browser 11 uses Firefox ESR 91, which brings an updated user interface containing new icons, a new toolbar, streamlined menus, dialogs, and an updated tabs interface.
When attempting to open a V2 onion service, Tor Browser will show users an "Invalid Onionsite Address" with an error code of 0xF6. "Last year we announced that v2 onion services would be deprecated in late 2021, and since its 10.5 release Tor Browser has been busy warning users who visit v2 onion sites of their upcoming retirement," the Tor Project explained in the Tor Browser 11 release notes.
"At long last, that day has finally come. Since updating to Tor 0.4.6.8 v2 onion services are no longer reachable in Tor Browser, and users will receive an"Invalid Onion Site Address" error instead.".
You can download Tor 11.0 from the Tor Browser download page and the distribution directory.
