What happened
Rust release stream (notably 1.96.1) includes security patches and dependency updates: Cargo fixes timeout/retry behavior; Cargo applies patches to libssh2 to address CVE-2025-15661, CVE-2026-55199, and CVE-2026-55200; rustc fixes a MIR optimization miscompilation. Earlier maintenance releases update tar to 0.4.45 (resolving CVE-2026-33055 and CVE-2026-33056) and include several platform/wasm fixes and other bug/security repairs. Users should upgrade to the patched toolchain to receive libssh2 and tar fixes and avoid the miscompilation bug in MIR optimizations.
