The Rust team has published a new point release of Rust, 1.94.1. Rust is a
programming language that is empowering everyone to build reliable and
efficient software.

If you have a previous version of Rust installed via rustup, getting Rust 1.94.1 is as easy as:

```
rustup update stable
```

If you don't have it already, you can [get `rustup`][rustup] from the appropriate page on our website.

[rustup]: https://www.rust-lang.org/install.html

## What's in 1.94.1

Rust 1.94.1 resolves three regressions that were introduced in the 1.94.0 release.

* [Fix `std::thread::spawn` on wasm32-wasip1-threads](https://github.com/rust-lang/rust/pull/153634)
* [Remove new methods added to `std::os::windows::fs::OpenOptionsExt`](https://github.com/rust-lang/rust/pull/153491)
The new methods were unstable, but the trait itself is not sealed and so
cannot be extended with non-default methods.
* [Clippy: fix ICE in `match_same_arms`](https://github.com/rust-lang/rust-clippy/pull/16685)
* [Cargo: downgrade curl-sys to 0.4.83](https://github.com/rust-lang/cargo/pull/16787)
This fixes certificate validation error for some users on some versions of
FreeBSD. See [this issue](https://github.com/rust-lang/cargo/issues/16357)
for more details.

And a security fix:

* [Cargo: Update tar to 0.4.45](https://github.com/rust-lang/cargo/pull/16769)
This resolves [CVE-2026-33055] and [CVE-2026-33056]. Users of crates.io are not affected.
See [blog](https://blog.rust-lang.org/2026/03/21/cve-2026-33056/) for more details.

[CVE-2026-33055]: https://www.cve.org/CVERecord?id=CVE-2026-33055
[CVE-2026-33056]: https://www.cve.org/CVERecord?id=CVE-2026-33056
