+## Migrating to an unstable edition
+
+After an edition is released, there is roughly a three year window before the next edition.
+During that window, new features may be added to the next edition, which will only be available on the [nightly channel].
+If you want to help test those new features before they are stabilized, you can use the nightly channel to try them out.
+
+The steps are roughly similar to the stable channel:
+
+1. Install the most recent nightly: `rustup update nightly`.
+2. Run `cargo +nightly fix --edition`.
+3. Edit `Cargo.toml` and place `cargo-features = ["edition2024"]` at the top (above `[package]`), and change the edition field to say `edition = "2024"`.
+4. Run `cargo +nightly check` to verify it now works in the new edition.

+| Release version | 1.82.0 (anticipated) |
+
+The Rust 2024 Edition is currently slated for release in Rust 1.82.0.
+Rust 1.82.0 will be in beta for six weeks,
+after which it is released as stable on October 17th.
+
+However, note that Rust is a project run by volunteers.
+We prioritize the personal well-being of everyone working on Rust
+over any deadlines and expectations we might have set.
+This could mean delaying the edition a version if necessary,
+or dropping a feature that turns out to be too difficult or stressful to finish in time.
+
+That said, we are on schedule and many of the difficult problems are already tackled,
+thanks to all the people contributing to Rust 2024! 💛
