Announcing Rust 1960 !link! 〈2024-2026〉

It is highly likely that 1960 is a typo for 1.60.0 . The Rust programming language did not exist in 1960, and version numbers are not currently in the thousands.

• std::sync::OnceLock: A thread-safe way to initialize a value once and access it immutably thereafter (a safer, simpler alternative to lazy_static for many use cases).
• std::io::Writer::write_all_vectored: Allowing more efficient I/O operations.

• Update rustup to the Rust 1960 toolchain and run cargo update; run your test suite and address any new warnings.
• Prefer incremental adoption: upgrade dependency versions and opt into new APIs one crate at a time for large workspaces.

Regardless of the specific version, you can always update to the latest stable release using Check current version rustc --version Use code with caution.
