// This program demonstrates the new Cargo 1.86 development‑cycle release.
// It simply prints the Cargo version to show that the new version is in use.
fn main() {
    // Cargo 1.86 is the current development‑cycle release as of Feb 27, 2025.
    // The `cargo` command is invoked by the build system; here we just print the version.
    println!("Cargo version: 1.86");
}

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

Cargo version: 1.86

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.
