The uutils project announced tonight the release of Rust Coreutils 0.3, another step forward for this Rust version alternative to GNU Coreutils that has been attracting a lot of interest lately due to Ubuntu 25.10 now using it by default.

Rust Coreutils 0.3 brings improved GNU test suite compatibility with now passing 532 tests, or nearly an 84% pass rate. There is improved error handling and other updates to better match the behavior of GNU Coreutils... Such as the recently noted [1]date issue breaking Ubuntu 25.10's unattended upgrades .

Rust Coreutils 0.3 also brings a number of performance improvements. Over GNU Coreutils, Rust Coreutils 0.3 is reporting its base64 implementation is 1.2x faster, expand is 1.8x faster, unexpand is 1.5x faster, nl is 1.57x faster, sort is as much as 3.72x faster, fold is 1.17x faster, and uniq is 1.13x faster.
