Once Arti is more mature, we may switch to using a separate changelog for each crate. +# Arti 2.5.1 - 3 August 2026 + +Arti 2.5.1 continues development on relays and directory authorities. +It also adds some perfomance, security, and convenience features for +onion services. + +<!-- Up to date as of f7b2611fa90c2b5b77a915248a8e4cb5283558b0 --> + +### Major bugfixes + +- Arti now interprets data rates in `XON` messages correctly. + Previously, it would interpret bytes per second as bits per second, + and send 8x less data than allowed. ([#2650], [!4255], [!4257]) + +### Breaking changes in lower-level crates + +- `tor-async-utils`: Moved the default implementation for + `PostageWatchSenderExt::maybe_send` to + the blanket implementation. ([!4214]) +- `tor-basic-utils`: Moved the default implementations for some `StrExt` + methods to the blanket implementation ([!4214]) +- `tor-basic-utils`: `RangeBoundExt`'s type parameter must now implement Ord. + ([!4214]) +- `tor-cell`: Renamed some `kbps` identifiers for clarity. ([!4255]) +- `tor-checkable`: Renamed `Timebound` to `TimeBound` and `TimerangeBound` + to `TimeRangeBound`. ([!4215]) +- `tor-checkable`: Renamed and refactored numerous time-bound-related + APIs. ([!4223]) +- `tor-config`: Removed `Built` from `BuilderExt`. ([!4214]) +- `tor-dirpublish`: Change argument type of `Uploader::upload`. ([!4243]) +- `tor-netdoc`: Removed `Eq` implementations on some types. (!4199]) +- `tor-netdoc`: Removed time checking and `now` argument from + `HsDesc::parse_decrypt_validate`. ([!4223]) +- `tor-netdoc`: Stop parsing, validating, or exposing (obsolete) TAP onion + keys. ([!4244]) +- `tor-netdoc`: Moved the default implementation for + `StrExt::strip_end_counted` to a blanket implementation. ([!4214]) +- `tor-proto`: Changed the API for `CreateRequestHandler::new()`. ([!4222]) + +### Onion service development + +- Onion services can now be configured to connect to `AF_UNIX` addresses. + ([!4129]) +- Clients and onion services can now negotiate + [Congestion control](https://blog.torproject.org/congestion-contrl-047/) + and + [Counter Galois Onion cryptography](https://blog.torproject.org/introducing-cgo/) + with one another, when the currently experimental + `hsc-negotiate-extensions` and `hss-negotiate-extensions` features + are enabled. ([#1948], [#2473], [!4135]) + +### Relay development + +- Infrastructure for validating and handling incoming relay messages. + ([#2606], [!4177]) +- Accept `BeginDir` and `Resolve` messges. ([#2613], [!4188]) +- Handle incoming `BeginDir` messages via an (as-yet-unfinished) + `DirMirror` type. ([!4222]) +- Encoding and generation for router descriptors. ([!4153]) +- Removed `Arc` wrapper around `KeyMgr`. ([!4221]) +- Backend support for negotiating circuits and extensions. ([!4171], [!4242]) +- New task to generate and upload router descriptors as needed. + ([#2549], [!4046]) +- Improve logging of peer addresses. ([!4245]) +- Additional tests for relay-side circuit handshakes. ([!4248], [!4254]) + +### Directory authority development + +- Improved APIs and methods for parsing and working with address and port + policies. + ([!4141], [!4191], [!4190]) +- Stabilize vote types and authcert encodings. ([!4189]) +- Support for calculating exit policy port summaries. ([!4198], [!4212]) +- Initial work to calculate directory consensuses. ([!4200]) +- Initial work on a command-line plugin tool to calculate consensuses for + C tor directory authorities. ([!4225]) +- Improved usibility for parsing APIs. ([!4235]) +- Full verification for router descriptors under new `parse2` + logic. ([!4144], [!4252]) +- Exposed more test utilities from `tor-netdoc`, for use in `tor-dirauth`. + ([!4250]) + +### Testing + +- Include support for fetching live test data to test voting and parsing + operations. ([!4224], [!4229], [!4237], [!4238], [!4249]) +- Integration tests now configure and initialize the network before + launching Shadow. ([#1683], [!4211]) +- Integration tests now use shadowtools to consolodate configuration and + logging. ([!4236]) + +### Documentation + +- Improve documentation for `iter_join`. ([!4213]) +- Better explanation of how to find good tickets for new contributors to work + on. ([!4226]) + +### Infrastructure + +- CI: Simplified our logic for pinning "nightly" to a particular release. + ([!4181]) +- CI: Upgraded to a newer version of Chutney for integration tests. ([!4197]) +- CI: Fixed a bug in usage of recent versions of `osxcross`. ([!4219]) +- CI: Use job tagging to force correct docker platforms. ([!4216]) + +### Cleanups, minor features, and bugfixes + +- Use a more recent (non-deprecated) format parsing API from the `time` + crate. ([28bf92c96fd5343d]) +- Upgraded several dependencies + (`aes`, `cipher`, `ctr`, `itertools`, `phf`, `rdrand`) + to more recent (but backward-incompatible) versions. + ([!4193], [!4194], [!4192], [!4195]) +- Better error messages for the case where any one of several + configuration options is required, but all are missing. ([!4131]) +- Resolve various new clippy warnings. ([!4203]) +- Used `derive-deftly` to refactor and simplify `RelayId` and `RelayidRef`. + ([!4196]) +- Ignore the `clippy::cognitivive_complexity` warning. + It has had a tendency to give false positives for functions that use + macros with internal branch complexity. ([#2556], [!4210]) +- Use the [`extend`](https://crates.io/crates/extend) crate to refactor and + simplify the declaration of our extension traits. ([!4214]) +- Replaced some instances of `allow(dead_code)` with feature-gates. + ([!4152]) +- Use correct Rust edition (2024) for `tor-dirsever` and `tor-dirauth` + crates. ([!4227]) +- Fixed an incorrect size check in `create_legacy_rsa_id_cert`. + ([#2626], [!4231]) +- Refactored the very large `bootstrap::download` function into + smaller pieces. ([!4204]) +- Removed feature-gating for `CircHop::handle_msg()`. ([!4230]) +- Rate-limit error reports about proxy failures. ([!4158]) +- Refactor document parsing to use `Intern` rather than `Arc` + for policies and versions. ([!4233]) +- Use `chunks_exact` rather than `as_chunks` to avoid clippy warnings. + ([!4240]) +- Avoid sending `DestroyReason` values other than `NONE`, to prevent + information leakage. ([#2578], [!4202]) +- Support for working with restricted sets of subprotocol capabilities. + ([!4241]) + +### Acknowledgments + +Thanks to everybody who's contributed to this release, including
