v2 onion services deprecation, Bug Smash 2021, Announcing Arti [HTML]

Onion service admins must upgrade to v3 onion services as soon as possible


If you are an onion site administrator, you must upgrade to v3 onion services as soon as possible.

As we announced last year, v2 onion services will be deprecated and obsolete in Tor 0.4.6.x. As of April 2021, Tor Browser Alpha uses this version of Tor and v2 addresses no longer work in this and future versions of Tor Browser Alpha.

When Tor Browser stable moves to Tor 0.4.6.x in October 2021, v2 onion addresses will be completely unreachable.

Why are we deprecating v2 onion services? Safety. Technologies used in v2 onion services are vulnerable to different kinds of attacks, and v2 onion services are no longer being developed or maintained. The new version of onion services provides improved encryption and enhanced privacy for administrators and users.

It's critical that onion service administrators migrate to v3 onion services and work to inform users about this change as soon as possible.

Help Tor Smash Bugs: August 1-31!


The Bug Smash Fund is back for its third year!

In 2019, we launched Tor’s Bug Smash Fund to raise money that would support our developers finding and fixing bugs in our software and to conduct routine maintenance. Maintenance isn’t a flashy new feature, and that makes it less interesting to many traditional funders, but it’s what keeps the reliable stuff working--and with your support, we’ve closed 370 Bug Smash Fund tickets.

For more on how you can contribute to the Bug Smash Fund, visit our blog: https://blog.torproject.org/tors-bug-smash-fund-2021

Announcing Arti, a pure-Rust Tor implementation


Over the past year or so, we've been working on "Arti", a project to rewrite Tor in Rust. Thanks to funding from Zcash Open Major Grants (ZOMG), we can finally put the Arti project up in our priorities list, and devote more time to it.

Read more about why we're doing this project, what it means for Tor users and operators, where it's going in the future, and how people can help: https://blog.torproject.org/announcing-arti

Transparency, Openness, and Our 2020 Financials


Every year, the Tor Project completes a Form 990 and independent audit of our financial statements. After completing standard audits for 2019-2020, our federal tax filings and audit are both available. We upload all of our tax documents and publish a blog post about these documents in order to be transparent.
