Mold Linker Version 3.0.0 Release – Rewritten in Rust

Mold 3.0.0 is a major tooling shift: the high-speed linker has been rewritten from C++ to Rust while maintaining drop-in compatibility and performance, reducing crash risk on malformed inputs and improving reliability for build pipelines. Strategically, the project is closing GNU ld compatibility gaps to become a default linker option in Linux distributions, which could simplify and standardize enterprise software builds over time. For IT organizations, this means validating build and release processes against a new Rust/Cargo-based toolchain and planning for minor workflow changes even though the binary behavior is intended to remain consistent.
