Understand it, then run it

The Rust team has released a pre‑release version of 1.96.1 for testing. A pre‑release is a version that is not yet considered stable but is available for developers to try out and give feedback on. It is scheduled to become the official stable release on June 30. The announcement does not change any language feature or API; it only informs you that a newer build is available for testing.

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

Hello, Rust 1.96.1 pre‑release testing!

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.
