v25.3.0
-
New: A specific clearer error if a valid non-empty diff changes no Rust source files, and so matches no mutants. Thanks to @brunoerg.
-
New: cargo-mutants can emit GitHub Actions structured annotations for missed mutants, which appear as warnings outside of the log text. This behavior is on by default when the
GITHUB_ACTIONenvironment variable is set, can be forced on with--annotations=githuband forced off with--annotations=none.
