The first stable release of the language was Rust 1.0.0, followed by Rust 1.1.0 and so on.

The latest release of this book, matching the latest Rust version, can always be found at <https://doc.rust-lang.org/reference/>.
Prior versions can be found by adding the Rust version before the "reference" directory.
For example, the Reference for Rust 1.49.0 is located at <https://doc.rust-lang.org/1.49.0/reference/>.
