// This program demonstrates that Danube Messaging 0.4.0 has been released.
// It simply prints a confirmation message; no actual library usage is shown
// because the change does not alter the public API in a way that requires
// code changes for existing users.

fn main() {
    println!("Danube Messaging 0.4.0 is now available with new features.");
}

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

Danube Messaging 0.4.0 is now available with new features.

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.
