Arti 2.6.0 released

by gabi | September 1, 2026

Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 2.6.0.

This release continues our ongoing development towards using Arti as a relay and as a directory authority, with much of the work focusing on document parsing, directory mirror support, and DNS stream handling. Additionally, on the RPC front, we are making steady progress towards RPC-based configuration management. Finally, congestion control and Counter Galois Onion cryptography are both now always enabled in arti.

As usual, there also are many under-the-hood improvements to our infrastructure, testing, and documentation, along with multiple bug fixes and internal cleanups.

For full details on what we've done, including API changes, and for information about many more minor and less-visible changes, please see the CHANGELOG.

For more information on using Arti, see our top-level README, and the documentation for the arti binary.

Thanks to everybody who's contributed to this release, including Andrew Kloet, Steven Masnada, iqdecay, pryty26, steven.

Also, our deep thanks to our sponsors for funding the development of Arti!
