Last month saw the release of Rust 1.87 that [1]celebrated ten years of the Rust programming language while out today is Rust 1.88 that continues iterating the language with new features.

Rust 1.88 introduces support for writing naked functions with no compiler-generated epilogue and prologue to allow for full control over the generated Assembly of that function. Naked functions are marked using the #[unsafe(naked)] attribute.

Rust 1.88 also adds support for chaining let statements inside if and while statements using "&&" chaining.

On the Cargo side, Rust 1.88 for Cargo brings automatic cache cleaning by running garbage collection on the cache within the home directory. Cargo currently is set to remove files downloaded from the network if not accessed in a three month period.

Rust 1.88 also brings support for boolean literals to the cfg predicate language, stabilized a number of APIs, and the i686-pc-windows-gnu target has been demoted to being a Tier-2 architecture.
