Version 1.31 of the Rust systems programming language is now available.
Current version: What’s new in Rust 1.31
Rust 1.31, released December 2018, marks the debut of “Rust 2018,” a new edition of the language with changes to syntax and concepts that are potentially backward incompatible.
By default, code compiled with Rust 1.31 uses the earlier Rust syntax rules, i.e. the “Rust 2015” rules. Code must be explicitly tagged with edition = '2018' to use the new Rust 2018 rules.
