Version 0.17.2 (2026-01-10)

Version 0.17.2 is mainly a patch fix to bugs related to the new ArrayRef implementation.

In addition, ndarray has reduced its packaging footprint to ease supply chain reviews (and shrink the binary size!). A special thanks to @​SwishSwushPow and @​weiznich for bringing this to our attention and making the necessary changes.

Added

• Add type aliases for higher-dimensional ArcArrays by @​varchasgopalaswamy #1561

Fixed

• Add PartialEq implementations between ArrayRef and ArrayBase by @​akern40 #1557
• Implement Sync for ArrayParts by @​gaumut #1552

Documentation

• fix some typos in comments by @​tinyfoolish #1547

Version 0.17.1 (2025-11-02)

Version 0.17.1 provides a patch to fix the originally-unsound implementation of the new array reference types.

The reference types are now all unsized. Practically speaking, this has one major implication: writing functions and traits that accept RawRef and LayoutRef will now need a + ?Sized bound to work ergonomically with ArrayRef. For example, the release notes for 0.17.0 said

Reading / Writing Shape: LayoutRef<A, D>

LayoutRef lets functions view or modify shape/stride information without touching data. This replaces verbose signatures like:

fn alter_view<S>(a: &mut ArrayBase<S, Ix1>)
where S: Data<Elem = f64>;

Use AsRef / AsMut for best compatibility:

fn alter_shape<T>(a: &mut T)
where T: AsMut<LayoutRef<f64>>;

However, these functions now need an additional bound to allow for callers to pass in &ArrayRef types:

fn alter_shape<T>(a: &mut T)
where T: AsMut<LayoutRef<f64>> + ?Sized; // Added bound here

A huge thank you to Sarah Quiñones (@​sarah-quinones) for catching the original unsound bug and helping to fix it. She does truly excellent work with faer-rs; check it out!
