Changelog

Sourced from num-bigint's changelog.

Release 0.5.1 (2026-07-04)

• Fixed a regression in the B-Z division algorithm.

Contributors: @​cuviper

Release 0.5.0 (2026-07-02)

• Upgrade to rand v0.10 and/or v0.9, and split rand_core.
  • The former rand feature is now split into multiple features, rand_0_9, rand_core_0_9, rand_0_10, and rand_core_0_10, depending on the version and feature set you need.
  • The RandBigInt extension trait is now split into BigRng09 and BigRng010 for each version.
  • The gen_* methods are deprecated in favor of new random_* methods.
  • This is also a value-breaking release, as rand defines it.

Note

Low Risk
Dependency-only bump with no application code changes; the upgrade includes a bigint division fix and keeps serde serialization behavior via the same feature flag.

Overview
Bumps the direct num-bigint dependency from 0.4.8 to 0.5.1 in Cargo.toml (still with the serde feature), with matching Cargo.lock updates.

The lockfile now pins num-bigint 0.5.1 for this crate while other packages in the graph continue to use 0.4.8 via num / clvmr. No Rust source changes—existing uses (e.g. ToBigInt) stay on the same API surface.
