This month's newsletter looks at Mexico lifting Tor restrictions on government sites, Tor's deployment of a new encryption mechanism for relays, and the anti-censorship team's lessons from combating blocks in Iran and Russia. Plus updates on Tor Browser Alpha's shift to a new release cycle and the latest Arti 1.8.0 features. Mexican government partially unblocks secure internet
Mexico blocked Tor access to government websites citing security concerns. The current administration lifted the main block earlier this year, though some sites appear to remain restricted. Ironically, the government had previously used Tor for its own anti-corruption whistleblower system while blocking citizens. Learn more in this guest post you can find on our blog.

Tor is upgrading its relay encryption algorithm for improved security. In upcoming releases, Arti and Tor will both support a new encryption algorithm called Counter Galois Onion (CGO). CGO prevents attackers from tampering with encrypted traffic, adds forward secrecy, and brings Tor's encryption up to modern standards. Find more details and detailed schematics here. Staying ahead of censors in 2025: What we've learned from fighting censorship in Iran and Russia
In 2025, Tor faced some of the toughest censorship yet. From Iran’s wartime internet blackouts to Russia’s rapidly evolving blocking tactics. Tor’s anti-censorship team sprung into action and strengthened Snowflake, deployed the new Conjure pluggable transport, and made WebTunnel more wide available. Thanks to real-time monitoring, community feedback, and faster bridge distribution, Tor keeps people connected when it matters most. Want to help? You can support our mission by running a Snowflake proxy or hosting a WebTunnel bridge. Learn more here. Keeping up with the latest releasesThe Future of Tor Browser Alpha
Starting with Tor Browser 16.0a1, the Tor Browser Alpha release channel will be based on Firefox Rapid Release rather than Firefox Extended Support Release. Among other factors, this means we are basically moving to one major feature release per year. You can find a full overview of the expected changes and our rationale behind making them here.
Arti 1.8.0Arti is our ongoing project to create a next-generation Tor implementation in Rust. Arti 1.8.0 introduces a new, usage-based, timeout for strongly isolated circuits.
