Announcing Rust 1.56.0 and Rust 2021

[Development] Posted Oct 21, 2021 19:35 UTC (Thu) by jake

The Rust language project has announced the release of stable version 1.56.0 and the Rust 2021 edition.

We wrote about plans for the Rust 2021 Edition in May. Editions are a mechanism for opt-in changes that may otherwise pose backwards compatibility risk. See the edition guide for details on how this is achieved. This is a smaller edition, especially compared to 2018, but there are still some nice quality-of-life changes that require an edition opt-in to avoid breaking some corner cases in existing code.

See the detailed release notes for 1.56.0 for lots more information on the release.
