[dependabot]

Updates the requirements on fearless_simd to permit the latest version.

Release notes

Sourced from fearless_simd's releases.

v0.5.0

Crates.io | Docs

This release has an [MSRV][] of 1.88.

Added

• The kernel! macro, which creates safe wrappers around SIMD-level-specific kernels so platform intrinsics from core::arch or std::arch can be used safely when a token proves the required target features. (#214[] by @​Shnatsel)
• The approximate_recip method on floating-point SIMD vector types. It uses fast hardware reciprocal estimates where available and exact division otherwise. (#204[] by @​tomcur)
• SimdMask::from_bitmask, SimdMask::to_bitmask, SimdMask::test, and SimdMask::set, mirroring the std::simd mask API. (#226[] by @​Shnatsel)

Changed

• Breaking change: the crate's SIMD extension traits are now sealed, so external crates can no longer implement them for their own types. (#211[] by @​LaurenzV)
• Breaking change: mask types now have opaque storage and use the new SimdMask trait instead of SimdBase. Masks no longer expose integer-vector APIs such as Deref, indexing, Bytes, public SimdSplit/SimdCombine, slide, slide_within_blocks, byte conversions, or scalar bit-operator overloads. (#218[] by @​Shnatsel)
• Generated SIMD loads, stores, reference casts, transmute-like conversions, helpers, const-generic functions, and intrinsic calls now use checked wrappers or kernel!, removing most unsafe from generated code. (#232[], #233[], #234[], #235[], #236[], #237[], #238[], #239[], #244[], #245[] by @​Shnatsel)
• Documentation and examples have been expanded and cleaned up for SIMD level tokens, mask types, platform-specific intrinsics, custom transmute wrappers, README consistency, and docs.rs visibility for NEON and WebAssembly APIs. (#213[], #221[], #222[], #230[], #240[], #243[] by @​Shnatsel, #224[], #225[] by @​DJMcNab)

Removed

• Breaking change: the core_arch wrapper module and the safe_wrappers feature have been removed. Use kernel! with core::arch or std::arch intrinsics instead. (#216[] by @​Shnatsel)

[0.4.1][] (2026-05-16)

This release has an [MSRV][] of 1.88.

Added

• The interleave and deinterleave methods on integer and floating-point SIMD vector types. (#206[] by [@​Shnatsel][])

Fixed

• Sse4_2 and Avx2 now consistently use the x86-64-v2 and x86-64-v3 feature sets for detection, dispatch, and generated target_feature attributes. (#208[] by [@​Shnatsel][])

[0.4.0][] (2026-02-13)

This release has an [MSRV][] of 1.88.

Added

• All vector types now implement Index and IndexMut. (#112[] by [@​Ralith][])
• 256-bit vector types now use native AVX2 intrinsics on supported platforms. (#115[] by [@​valadaptive][])
• 8-bit integer multiplication is now implemented on x86. (#115[] by [@​valadaptive][])
• New native-width associated types: f64s and mask64s. (#125[] by [@​valadaptive][])
• The bitwise "not" operation on integer vector types. (#130[] by [@​valadaptive][])
• The from_fn method on vector types. (#137[] by [@​valadaptive][])
• The load_interleaved and store_interleaved operations now use native intrinsics on x86, instead of using the fallback implementations. (#140[] by [@​valadaptive][])
• Add support for relaxed_simd operations in WebAssembly. (#143[] by [@​valadaptive][])
• The ceil and round_ties_even operations on floating-point vector types. (Rust's round operation rounds away from zero in the case of ties. Many architectures do not natively implement that behavior, so it's omitted.) (#145[] by [@​valadaptive][])
• A prelude module, which exports all the traits in the library but not the types. (#149[] by [@​valadaptive][])
• The any_true, all_true, any_false, and all_false methods on mask types. (#141[] by [@​valadaptive][])
