Understand it, then run it
The release notes list several new versions of tools and libraries: Creusot 0.9.0, diesel‑guard 0.5.0, skim 1.0.0, d‑engine, govctl, Burn 0.20.0, and git‑cliff 2.12.0. These are all separate crates that developers can add to their projects. Nothing in the source changes the Rust language itself; it only announces that these crates are now available. If you want to use one of them, you add it to your Cargo.toml and import the symbols it exports.
Run it now
// This program simply prints the list of newly released tooling versions.
// It demonstrates that the change is a release announcement, not a language feature.

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.
