  "textContent": "Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 2.2.0.\n\nThis release adds support for using HTTP CONNECT rather than SOCKS, when connecting to the Tor network via Arti. This previously-experimental feature is now included a `full` build, and will then be enabled by default. The HTTP CONNECT protocol is available over the same port as SOCKS.\n\nThe RPC client library (`arti-rpc-client-core`) now supports non-blocking requests, and integration with application event loops. And the RPC system now supports administrative access to the Arti instance, via a new \"superuser\" facility.\n\nWe also fixed a low-severity security issue, TROVE-2026-005, which would somewhat weaken DoS resistance in in certain unusual embedded build configurations.\n\nBehind the scenes we have been working on relay support, including relay channels and circuits, and directory server functionality (mirrors and authorities). As ever there are also lots of bugfixes, cleanups, and test and CI improvements.\n\nFor 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.\n\nFor more information on using Arti, see our top-level README, and the documentation for the arti binary.\n\nThanks to everybody who's contributed to this release, including hjrgrn, HydroxideUnlaced, Nihal, and Tobias Stoeckmann.\n\nAlso, our deep thanks to our sponsors for funding the development of Arti!\n\n  * \n          announcements\n        \n  * \n          releases\n        \n\n",
