Rust Release Changelog - 1.97.0
summary
Series-style recap lists concrete changes: crater (60–70% of crates io) and outreach around symbol mangling V0, a new cargo build warnings env var, linker output shown by default, must_use treating Result<T, uninhabited> as T with plans to alias infallible to never, partial LoongArch and nvptx64 pruning, a cfg for atomic alignment, platform tier policy, and community process changes like Bevy 1,185 contributors and Clippy’s open code review. Watch if value is in specific rules, numbers, and tooling links; skip if only a deep technical demo is wanted.
