It is intended as a drop-in replacement for 2.42.1 with the same command-line options, target architectures, output, and on-par linking performance, while closing GNU ld compatibility gaps especially around linker scripts. The build system moved from CMake to Cargo, requires Rust 1.95+ and a C compiler, drops oneTBB, statically links mimalloc 3.5.3, and adds bounds-checked handling for corrupted input files; the Hacker News thread has 207 points and 122 comments. Why: If you self-build mold or maintain CI/distro packaging for it, you must switch from CMake to Cargo, ensure Rust 1.95+, use ./install-mold.sh with PREFIX/DESTDIR, and set MOLD_LIBDIR for installs where libraries go outside $PREFIX/lib so mold -run can find mold-wrapper.so. Otherwise, the upgrade is meant to be drop-in for 2.42.1, so test linker scripts and GNU ld compatibility before making it default. There is no Malaysia-specific hook; local impact is limited to teams whose toolchain or packaging uses mold. rust linker build-systems developer-tools open-source
