Rust 1.97.1 has been released as a point release to fix a miscompilation bug caused by an LLVM optimization. The fix includes both a backported LLVM patch and a disable of the underlying IR change introduced in Rust 1.97.0 that increased the likelihood of triggering the bug. Notably, the underlying miscompilation has been present since at least Rust 1.87. Users can update via `rustup update stable`.
