1.86.0 # Released on: 3 April, 2025 Branched from master on: 14 February, 2025 Language # Stabilize upcasting trait objects to supertraits. Allow safe functions to be marked with the #[target_feature] attribute. The missing_abi lint now warns-by-default. Rust now lints about double negations, to catch cases that might have intended to be a prefix decrement operator (--x) as written in other languages. This was previously a clippy lint, clippy::double_neg, and is now available directly in Rust as double_negations. More pointers are now detected as definitely not-null based on their alignment in const eval. Empty repr() attribute applied to invalid items are now correctly rejected. Inner attributes #![test] and #![rustfmt::skip] are no longer accepted in more places than intended.
