Arti 1.8.0 released: Onion service improvements, prop 368, relay development, and more.

Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 1.8.0.

This release introduces a new, usage-based, timeout for strongly isolated circuits, as specified in proposal 368.

Arti now has experimental tokio-console support for development and debugging purposes. To use this feature, you will need to build Arti with the experimental tokio-console cargo feature and --cfg tokio_unstable, and enable the tokio_console option in the config.

This release also brings some of quality of life improvements for onion services, with the new experimental arti hsc ctor-migrate command for migrating C Tor client restricted discovery keys (previously known as "client authorization keys") to Arti's keystore, and a configuration option for controlling which onion services to launch.

Behind the scenes, we have continued development of functionality required to support relays and directory authorities. This development has focused on the routing architecture and protocol implementation (circuits and channels), parsing and generating Tor network documents, directory cache support, and on implementing the OR port listener and the associated configuration.

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 Dimitris Apostolou, hashcatHitman, hjrgrn, Mynacol, Neel Chauhan, nield, Nihal, NoisyCoil.

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