bytemuck changelog

1.23

• impl_core_error crate feature adds core::error::Error impl.
• More ZeroableInOption impls.

1.22

• Add the pod_saturating feature, which adds Pod impls for Saturating<T> when T is already Pod.
• A bump in the minimum bytemuck_derive dependency from 1.4.0 to 1.4.1 to avoid a bug if you have a truly ancient cargo.lock file sitting around.
• Adds Send and Sync impls to BoxBytes.

1.21

• Implement Pod and Zeroable for core::arch::{x86, x86_64}::__m512, __m512d and __m512i without nightly. Requires Rust 1.72, and is gated through the avx512_simd cargo feature.
• Allow the use of must_cast_mut and must_cast_slice_mut in const contexts. Requires Rust 1.83, and is gated through the must_cast_extra cargo feature.
• internal: introduced the maybe_const_fn macro that allows defining some function to be const depending upon some cfg predicate.

1.20

• New functions to allocate zeroed Arc and Rc. Requires Rust 1.82
• TransparentWrapper impls for core::cmp::Reverse and core::num::Saturating.
• internal: Simplified the library's fill_zeroes calls to write_bytes

1.19

• Adds the #[track_caller] attribute to functions which may panic.

1.18

• Adds the latest_stable_rust cargo feature, which is a blanket feature that turns all other features on that are both sound and compatible with Stable rust.

1.17.1

• Adds #[repr(C)] to the union Transmute<A, B> type that's used internally for most of the transmutations.

1.17.0

• Makes the must_cast versions of the by-value and by-ref casts be const. The mut ref cast is unaffected for now (mut references aren't yet stable in const fn). This increases the MSRV of using that particular feature from 1.57 to 1.64.

1.16.3
