"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. 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."
Rust 1.93, released January 22, upgrades *-linux-musl targets to ship with musl 1.2.5. Developers with rustup-installed Rust can upgrade by running rust update stable. The change mainly affects static musl builds for x86_64, aarch64, and powerpc64le that previously bundled musl 1.2.3. The motivation is to incorporate major DNS resolver improvements introduced in musl 1.2.4 and subsequent bug fixes in 1.2.5. For static-linked musl targets, the update should produce more reliable portable Linux binaries for networking, improving resilience against large DNS records and issues with recursive name servers.
