What happened
Multiple Rust releases (1.94.1 through 1.97.1) containing compiler fixes, platform updates, and security patches. Notable security items: Cargo applies patches to libssh2 addressing CVE-2025-15661, CVE-2026-55199, and CVE-2026-55200; Cargo updates the tar crate to resolve CVE-2026-33055 and CVE-2026-33056 (the release notes state crates.io users are not affected). rustc received several miscompilation fixes (MIR and LLVM optimization fixes; 1.97.1 backports an LLVM-side fix and reverts a rustc change to avoid the trigger). Other changes include platform/target feature stabilizations and misc.
