Release rayon 1.11.0 / rayon-core 1.13.0 (2025-08-12)

• The minimum supported rustc is now 1.80.
• iter::repeatn has been renamed to iter::repeat_n to match the name stabilized in the standard library. The old name still exists as a deprecated function for compatibility.
• Fixed a bug in in_place_scope when the default global registry uses the current thread, like on WebAssembly without threading support.
• binary_heap::Iter no longer requires a temporary allocation.
• Relaxed trait bounds on many of the public structs.
• Implemented IntoParallelIterator for Box<[T]> and its references.
• Implemented FromParallelIterator<_> for Box<str> via String.

Release rayon 1.10.0 (2024-03-23)

• The new methods ParallelSlice::par_chunk_by and ParallelSliceMut::par_chunk_by_mut work like the slice methods chunk_by and chunk_by_mut added in Rust 1.77.

Release rayon 1.9.0 (2024-02-27)

• The new methods IndexedParallelIterator::by_exponential_blocks and by_uniform_blocks allow processing items in smaller groups at a time.
• The new iter::walk_tree, walk_tree_prefix, and walk_tree_postfix functions enable custom parallel iteration over tree-like structures.
• The new method ParallelIterator::collect_vec_list returns items as a linked list of vectors, which is an efficient mode of parallel collection used by many of the internal implementations of collect.
• The new methods ParallelSliceMut::par_split_inclusive_mut, ParallelSlice::par_split_inclusive, and ParallelString::par_split_inclusive all work like a normal split but keeping the separator as part of the left slice.
• The new ParallelString::par_split_ascii_whitespace splits only on ASCII whitespace, which is faster than including Unicode multi-byte whitespace.
• OsString now implements FromParallelIterator<_> and ParallelExtend<_> for a few item types similar to the standard FromIterator and Extend.
• The internal Pattern trait for string methods is now implemented for [char; N] and &[char; N], matching any of the given characters.

Release rayon 1.8.1 / rayon-core 1.12.1 (2024-01-17)

• The new "web_spin_lock" crate feature makes mutexes spin on the main browser thread in WebAssembly, rather than suffer an error about forbidden atomics.wait if they were to block in that context. Thanks @​RReverser!
