Version 1.100.0 of the Rust programming language has been released. It includes a huge number of stabilized features, such as the never type, the DropGuard type in the standard library, and the Allocator API. Cargo can also now set a minimum age for dependencies, to stop supply chain attacks, and can point out unused dependencies more reliably. Taken together, many users depending on unstable features may be able to switch to the stable version of the compiler.
