chore(deps): bump arbitrary from 1.4.2 to 1.5.0 by dependabot[bot] · Pull Request #1933 · hyperlight-dev/hyperlight

dependabot · 2026-10-14T14:13:55Z

Bumps arbitrary from 1.4.2 to 1.5.0.

Changelog

1.5.0

Released 2026-10-05.

Added

Added support for deriving Arbitrary for types with raw identifiers.

Changed

Updated derive_arbitrary to syn 3. This raises the MSRV from 1.63.0 to 1.71.0, which is the MSRV of syn 3.

Fixed

Fixed soundness when generating arrays.

Fixed nonzero integer generation to always produce a nonzero value.

Updated derive_arbitrary to include fixes for fully qualified paths.
