Also in Rust 1.91, the team has added a warn-by-default lint on raw pointers to local variables being returned from functions. Although Rust’s borrow checking prevents dangling references from being returned, it does not track raw pointers.
Rust 1.91 also stabilizes 60 APIs and makes seven previously stable APIs stable in const contexts. The release also stabilizes the build.build-dir config of the Cargo package manager. This config sets the directory where intermediate build artifacts are stored, the Rust Release Team said. These artifacts are produced by Cargo and rustc during the build process.
Rust 1.91 follows the September 18 release of Rust 1.90. That release offered native support for workspace publishing for Cargo.
