arti: update to 2.4.0.

# Arti 2.4.0 — 1 June 2026

Arti 2.4.0 continues our work on relay and directory authority development,
and brings us even closer to a working middle relay.

This release also includes a number of important
bug fixes in our onion service client implementation,
and a number of breaking changes in the `arti-client` APIs.

Log message:
arti: update to 2.3.0.

# Arti 2.3.0 — 6 April 2026

Arti 2.3.0 continues development on relay, directory authority, and RPC \ 
functionality.
It also adds a couple new logging-related features, including the ability to log \ 
to syslog.
We have also made improvements in memory usage, by moving the GeoIP database out \ 
of the
heap and optimizing the format it's stored in.

Users of the `arti-client` crate should note that in the release following this one,
`TorClient` will be explicitly wrapped in an `Arc`, rather than implicitly having
Arc-like semantics. Be prepared for this breaking change next release, and feel free
to comment in [#2469] if you have any thoughts on this change.

Log message:
arti: update to 2.2.0.

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.

Log message:
arti: update to 2.1.0.

# Arti 2.1.0 — 2 March 2026

Arti 2.1.0 continues work on relay development,
and introduces a new RPC backend with non-blocking IO
in the `arti-rpc-client-core` library.

As usual, there are also various under-the-hood improvements and bug fixes.

Log message:
arti: update to 2.0.0.

# Arti 2.0.0 — 2 February 2026

Arti 2.0.0 deprecates library functionality in the `arti` crate
(which should only be used as a binary),
deprecates some legacy features and configuration formats,
and adds support for using the `inet-auto` socket type
to automatically pick an unused TCP port for the RPC server.
As usual, there is also a significant amount of behind-the-scenes work on
relay and directory authority functionality.

While "2.0" may sound like an exciting release number, it's actually \ 
fairly mundane.
[Semver](https://semver.org) requires us to bump our major version number when \ 
making breaking changes,
and we had a couple breaking changes we wanted to make in order to keep our APIs \ 
tidy.
The only people who should notice significant changes in this release are developers
who are building applications using the `arti` crate directly,
rather than the recommended `arti-client` crate or other lower-level crates.

Log message:
arti: update to 1.9.0.

# Arti 1.9.0 — 13 January 2026

Arti 1.9.0 continues some behind-the-scenes work on relay and
directory authority development, and adds improved support for
running with dynamically assigned ports. For example Arti now
accepts `proxy.socks_listen = "auto"` to configure its SOCKS proxy
with an operating-system-assigned port, and writes the assigned
port to a structured JSON file in Arti's data directory.

As usual, there are also various under-the-hood improvements and
bug fixes.

Log message:
arti: update to 1.8.0.

# Arti 1.8.0 — 1 December 2025

Arti 1.8.0 continues work on relay and directory authority development.
This release introduces a new, usage-based timeout for strongly isolated circuits,
experimental [`tokio-console`] support, a new `arti hsc ctor-migrate` command,
and a configuration option for controlling which onion services to launch.

As usual, there are also various under-the-hood improvements and bug fixes.

Log message:
arti: update to 1.7.0.

Arti 1.7.0 continues high-level and low-level work on relay development.

It also includes new experimental support for running as a `HTTP CONNECT`
proxy, and numerous smaller fixes and infrastructure improvements.

Log message:
arti: update to 1.6.0.

Arti 1.6.0 brings experimental support for circuit padding,
mitigations for DropMark side channel attacks, improvements to
congestion control, a new `arti keys check-integrity` command, and
experimental support for exporting debugging information via
OpenTelemetry.

It also includes behind-the-scenes work towards enabling Arti to
act as a directory authority, a directory mirror, and a relay.

Log message:
arti: update to 1.5.0.

# Arti 1.5.0 — 28 August 2025

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 preliminary 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.

As usual, there are also various under-the-hood improvements and
bug fixes.
