The format is based on Keep a Changelog, and this library adheres to Rust's notion of Semantic Versioning.

[Unreleased]

[0.13.0] - 2022-12-06

Changed

• Bumped ff to 0.13

[0.12.1] - 2022-10-13

Added

• group::{WnafBase, WnafScalar} structs for caching precomputations of both bases and scalars, for improved many-base many-scalar multiplication performance.
• impl memuse::DynamicUsage for group::{Wnaf WnafBase, WnafScalar}, behind the new wnaf-memuse feature flag, to enable the heap usage of these types to be measured at runtime.

Changed

• Removed temporary allocations from Wnaf internals for improved performance.

[0.12.0] - 2022-05-04

Changed

• MSRV is now 1.56.0.
• Bumped ff to 0.12

[0.11.0] - 2021-09-02

Fixed

• The affine scalar multiplication bounds on the following traits had typos that prevented multiplying by &Self::Scalar, which has now been fixed:
  • group::cofactor::{CofactorCurve::Affine, CofactorCurveAffine}
  • group::prime::{PrimeCurve::Affine, PrimeCurveAffine}

Added

• Copy + Send + Sync + 'static bounds on group::GroupEncoding::Repr.

Changed

• Bumped ff to 0.11.

[0.10.0] - 2021-06-01

Added

• group::ff, which re-exports the ff crate to make version-matching easier.

Changed

• MSRV is now 1.51.0.
• Bumped ff to 0.10.

Removed

• group::cofactor::CofactorGroup::is_torsion_free provided implementation (trait implementors must now implement this method themselves). This avoids a hard dependency on the ff/bits feature flag.

[0.9.0] - 2021-01-06

Changed

• Bumped dependencies to ff 0.9, rand_core 0.6, rand 0.8.

[0.8.0] - 2020-09-08

Added

• no_std support.

Changed

• MSRV is now 1.44.0.
• Bumped ff to 0.8.
• group::{wnaf, Wnaf, WnafGroup} are now gated behind the (default-enabled) alloc feature flag. The byteorder dependency is now optional.
• group::tests is now gated behind the tests feature flag. The rand and rand_xorshift dependencies are now optional.

Removed

• fmt::Display bound from the following traits:
  • group::Group
  • group::cofactor::CofactorCurveAffine
  • group::prime::PrimeCurveAffine
