Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 1.5.0.

Arti 1.5.0 continues development on important client features, including Counter Galois Onion encryption, Conflux, flow control and congestion control, and onion service proof of work. It also includes significant backend work for Arti relay support.

Additionally, this release mitigates a longstanding bug that could prevent Arti clients from bootstrapping.

Arti 1.5.0 increases our MSRV (Minimum Supported Rust Version) to 1.85, in accordance with our MSRV policy.

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 hashcatHitman, Jérôme Charaoui, luciole, Neel Chauhan, Niel Duysters, thesw4rm, Omar Gorni, and Tobias Stoeckmann.

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