+# Rust 2024 in beta channel
+
+The next edition, Rust 2024, has entered the beta channel.  It will live there until 2025-02-20, when Rust 1.85 and Rust 2024 will be released as stable.
+
+We're really happy with how Rust 2024 has turned out, and we're looking forward to putting it in your hands.
+
+You can get a head start in preparing your code for the new edition, and simultaneously help us with final testing of Rust 2024, by following these steps within a project:
+
+1. Run `rustup update beta`.
+2. Run `cargo update`.
+3. Run `cargo +beta fix --edition`.
+4. Set `edition = "2024"` and, if needed, `rust-version = "1.85"`, in `Cargo.toml`.
+5. Run `cargo +beta check`, address any remaining warnings, and then run other tests.
+
+More details on how to migrate can be found [here](https://doc.rust-lang.org/nightly/edition-guide/editions/transitioning-an-existing-project-to-a-new-edition.html) and within each of the [chapters](https://doc.rust-lang.org/nightly/edition-guide/rust-2024/) describing the changes in Rust 2024.  For more on the changes themselves, see the [Edition Guide](https://doc.rust-lang.org/nightly/edition-guide/).
