Changelog

Sourced from group's changelog.

[0.14.0] - 2026-06-01

Added

• group::CurveAffine, an affine-representation trait that the curve-specific affine traits are now built on top of.
• group::Group::mul_by_generator, with a default implementation. Implementors can override it to take advantage of precomputed tables.
• group::Group::try_random<R: TryRng + ?Sized>(rng: &mut R) -> Result<Self, R::Error>, a new trait method that must be implemented by downstreams. It samples a non-identity group element using a fallible RNG and propagates the RNG's error.

Changed

• MSRV is now 1.85.0.
• Bumped dependencies to ff 0.14, rand_core 0.10.
• group::Group::random(rng: impl RngCore) -> Self has been changed to Group::random<R: Rng + ?Sized>(rng: &mut R) -> Self, to enable passing a trait object as the RNG. It now has a default implementation in terms of Group::try_random.
• The curve-related traits have been refactored around the new CurveAffine trait:
  • group::Curve::AffineRepr has been renamed to Curve::Affine.
  • All of the trait methods and associated types on the following traits have been removed (use group::Curve::Affine or the group::CurveAffine trait instead; trait implementors must implement group::CurveAffine instead using the same logic):
    • group::cofactor::CofactorCurve
    • group::cofactor::CofactorCurveAffine
    • group::prime::PrimeCurve
    • group::prime::PrimeCurveAffine
  • group::cofactor::CofactorCurveAffine and group::prime::PrimeCurveAffine now have blanket implementations for all types C: group::CurveAffine where C::Curve implements CofactorCurve or PrimeCurve respectively.
