Once Arti is more mature, we may switch to using a separate changelog for each crate. -# Arti 2.1.0 — 2 March 2026 +# Arti 2.2.0 — 31 March 2026 + +DONE up through 7a7401b0ddb159bcbc949b2d873ad5c931edd12d + +Arti 2.2.0 continues our work on relay development, +and brings us even closer to a working middle relay. + +This release also adds some useful client-side features, +and includes various bugfixes and cleanups, +all listed below. + +### Breaking changes + +<!-- Breaking changes to `arti` or `arti-client` --> + +### Security fixes + +- Fixed a low-severity issue where, + if an application embedding arti also included the `weak-table` crate, + and that application built `weak-table` with `ahash` enabled, + the application would be somewhat less DoS-resistant + when running on applications without hardware AES support. + ([#2412], [!3801], [TROVE-2026-005]) + +### Major features + +- The `http-connect` feature, which enables arti to run as an HTTP CONNECT + proxy, is now stable. ([#2409], [!3811]) +- Clients now support outbound HTTP CONNECT proxies. + (Previously, they only supported outbound SOCKS proxies.) ([!3789]) + +### Breaking changes in lower-level crates + +- Removed `IoErrorExt` and `BinaryHeapExt` from `tor-basic-utils`. + Both of these traits implemented functionality that is now available + in the standard library. ([074072ad66bf35e1]) +- In `tor-netdoc`, renamed some `*Signed` types to `*Unverified`, + to avoid ambiguity. ([9018c73d34ca60c5]) +- In `tor-dirclient`, renamed `DirResponse::from_body` to + `from_get_body`. ([04e8874058966f45]) +- In `tor-keymgr`, replace `KeySpecifier::has_certificate` + with usage of the new `CertSpecifier` macro. ([efa1e2540f9c23c5]) +- Throughout all crates, + all APIs that used to accept or return an `Instant` + now accept or return a `web_time::Instant` + when built on the `wasm32-unknown-unknown` target. + ([!3820]) + +### Relay development + +- Continued development on channel authentication handshakes. + Relays can now successfully accept incoming TLS connections, + and authenticate to clients and other relays. + ([#2388], [!3732], [!3736], [!3745], [!3773], [!3791], [!3795]) +- Relay channels now do a better job tracking the actual addresses + of their peers. ([#2375], [!3722]) +- Continued development on improved directory object parsing and + verification, with a focus on signature handling and generation. + ([!3742], [!3765]) +- Continued development on directory cache operation, including + migration to a less complex backend, + and database improvements. + ([!3664]) +- Changed TLS certificate to use RSA2048 subject keys, to work around + [a bug in the C tor implementation][tor#41226]. ([#2403], [!3769]) +- Improved and refactored key-manager operations for better handling of + relay certificates and related keys. + ([#2376], [#2377], [!3770], [!3754], [!3785]) +- Use our key manager to manage relay certificates. ([#2404], [!3782]) +- Switched to a [forked version of `ssh-key`] with workarounds and bugfixes + needed to support some legacy key types. ([#2398], [!3783]) +- The directory client logic now supports requesting "extra-info" documents. + ([!3764]) +- Maintain a list of unauthenticated channels from clients and bridges. + ([!3790]) +- Extended circuit logic to accommodate differences between relays' and + clients' views of half-open streams and timeout estimation. + ([#2410], [!3794]) +- Improved the ergonomics for various relay-visible logs. ([!3776], [!3803], + [!3806], [!3807]) +- API preparation for handling CREATE2 and CREATE_FAST + cells. ([!3809]) +- Backend logic for consensus diff generation, based on the [`imara-diff`] + crate. ([!3712], [!3815]) +- Forward outbound RELAY_EARLY cells correctly. ([#2417], [!3810]) +- Use correct memory quota buckets when extending circuits. ([!3821]) + +### RPC development + +- The RPC client library (`arti-rpc-client-core`) + now supports non-blocking requests, + and integration with application event loops. + As with the rest of the RPC client library, + this code has APIs wrappers in Rust, C, and Python, + and Python integration tests. + ([#1856], [!3652], [!3762], [!3771], [!3774]) +- The RPC system now supports "superuser" capabilities, + which applications can use to change and observe parts of Arti + that affect the entire system + (and not only the application's own traffic). + ([#2285], [!3743]) + +### Testing + +- Python tests are now more robust to [`mypy` issue 20962]. ([!3744]) +- Our chutney-based test scripts have been converted to Python, + for better integration with the rest of [chutney]. ([!3735], [!3756]) +- Fixed a bug in our chutney benchmark tests where we would use the wrong + binary. ([!3758]) +- Revised testing infrastructure for `keymgr` code. ([!3761]) +- Clarifications, cleanups, and renamings in the sub-command + integration test suite. ([!3827]) + +### Documentation -<!-- up to date with ba4163ed943a67cd8a55f7291797fb22a788f950 --> +- Removed or softened various warnings about the security limitations of + earlier versions of Arti. ([#2000], [#2063], [!3748], [!3812]) +- Removed an obsolete version of our roadmap. ([a3bb97e945addd2e]) +- Improved internal documentation concerning what it means for a + directory request to be "anonymized". ([!3767]) +- Our consensus flag documentation now links to the specs. + ([!3768]) +- Describe the correct configuration file path on Windows. + ([#2422], [!3808]) + +### Infrastructure + +- Report better results from failing shadow CI runs. ([!3766]) +- Enabled more features in our CI testing builds. This will help us + test more experimental features before they stabilize. ([!3772], [!3759]) + +### Cleanups, minor features, and bugfixes + +- Added an internal `MaybeSensitive` for wrapper for objects that are + _conditionally_ risky log. ([501ba52b79814425]) +- Allow use of now-deprecated `UnboundedReceiver::try_next()` in tests. + ([800a47ea1203d87e]) +- Increased required versions of various dependencies. ([!3746]) +- Arti now builds with a broader range of versions of `libsqlite3-sys`. + This should make it easier to embed Arti in environments that + require specific versions. ([#1740], [!3706]) +- Empty directory responsees are now treated as an error. ([!3650]) +- Upgrade to the latest [`polyval`] crate, to improve [CGO] performance. + ([#2390], [!3747]) +- Added a `RelayDetails::is_flaged_exit()` method to help applications + tell whether a relay has the `Exit` flag. ([!3752]) +- Improved cross compilation on systems without a C compiler. + ([#2366], [!3778]) +- Fix compilation warnings on Windows. ([!3780]) +- Various typo and grammar fixes. ([!3781], [!3792]) +- Fix a bug in certificate expiry time calculation, + which would make our unit tests fail if run + during the first second of an hour. ([#2407], [!3787]) +- Update to the latest GeoIP database. ([!3813]) +- Refactored retry_error logic. ([!3784]) +- Simplified some of the feature-gating in tor-proto. ([!3796]) +- Fixed unusable duration formatting in tor-guardmgr's log + messages. ([!3804]) +- Arti now builds with fewer warnings and errors + on the wasm32-unknown-unknown platform. + (This is meant to help people who would like + to experiment with wasm ports.) ([!3814], [!3816], [!3818], [!3819]) +- Include a compatibility layer for using web_time on + the wasm32-unknown-unknown platform. + ([#2356], [!3820]) + + +### Acknowledgments + +Thanks to everybody who's contributed to this release, including +hjrgrn, HydroxideUnlaced, Nihal, and Tobias Stoeckmann. +Also, our deep thanks to +the [Bureau of Democracy, Human Rights, and Labor], +and our [other sponsors] +for funding the development of Arti! + +<!-- links go here --> + +[!3650]: https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3650 +[!3652]:
