Rust 1.84.1 is a patch release that mainly fixes bugs and improves security. It does not add new features or change existing syntax. The change is a maintenance update that keeps the language stable and safe.

Run it now

Todayrust
// This program demonstrates that Rust 1.84.1 compiles and runs as usual.
// It simply prints a message to confirm the environment is working.
fn main() {
    // Print a greeting
    println!("Hello, Rust 1.84.1 is running!");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

Hello, Rust 1.84.1 is running!

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
