Mar. 28, 2023 · The Rust Release Team

The Rust team has published a new point release of Rust, 1.68.2. 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, you can get 1.68.2 with:

rustup update stable

If you don't have it already, you can get rustup from the appropriate page on our website, and check out the detailed release notes for 1.68.2 on GitHub.

What's in 1.68.2 stable

Rust 1.68.2 addresses GitHub's recent rotation of their RSA SSH host key, which happened on March 24th 2023 after their previous key accidentally leaked:

Support for @revoked entries in .ssh/known_hosts (along with a better error message when the unsupported @cert-authority entries are used) is also included in Rust 1.68.2, as that change was a pre-requisite for backporting the hardcoded revocation.

If you cannot upgrade to Rust 1.68.2, we recommend following GitHub's instructions on updating the trusted keys in your system. Note that the keys bundled in Cargo are only used if no trusted key for is found on the system.
