The Rust team has unveiled Rust 1.93, the latest version of the programming language designed to create fast and safe system-level software. This release improves operations involving the DNS resolver for the musl implementation of the C standard library. Linux binaries are expected to be more reliable for networking as a result.
Rust 1.93 was introduced January 22. Developers with previous versions of Rust installed via rustup can upgrade by running rust update stable.
With Rust 1.93, *-linux-musltargets will ship with musl 1.2.5. This mostly affects static musl builds for x86_64, aarch64, and powerpc64le, which bundled musl 1.2.3, the Rust team said. For the Rust ecosystem, the primary motivation for this update is to receive major improvements to musl’s DNS resolver that shipped in release 1.2.4 and received bug fixes in release 1.2.5. When using musl targets for static linking, the update should make portable Linux binaries that do networking more reliable, particularly in the face of large DNS records and recursive name servers.
