Bugfixes

v0.4.0

Breaking changes

• #300 (ark-ec) Change the implementation of Hash trait of GroupProjective to use the affine coordinates.
• #302 (ark-ff) Rename find_wnaf to find_naf.
• #310 (ark-ec, ark-ff) Remove unnecessary internal PhantomData.
• #333 (ark-poly) Expose more properties of EvaluationDomains.
• #338 (ark-ec) Add missing UniformRand trait bound to GroupAffine.
• #338 (workspace) Change to Rust 2021 edition.
• #345 (ark-ec, ark-serialize) Change the serialization format for Twisted Edwards Curves. We now encode the Y coordinate and take the sign bit of the X coordinate, the default flag is also now the Positive X value. The old methods for backwards compatibility are located here
• #348 (ark-ec) Rename msm:{Fixed,Variable}BaseMSM:multi_scalar_mul to msm:{Fixed,Variable}:msm to avoid redundancy.
• #359 (ark-test-templates) Simplify the field and curve test macros.
• #365 (ark-ec)
  • Move COFACTOR, COFACTOR_INV, and is_in_correct_subgroup_assuming_on_curve() from {SW,TE}CurveConfig to CurveConfig.
  • Add mul_bits() to AffineCurve and provide a default implementation of mul() using this.
  • Remove duplicate function scale_by_cofactor() from short_weierstrass::GroupAffine and twisted_edwards_extended::GroupAffine
• #370 (all) Set the minimum rust-version = 1.56 in the manifests of all crates.
• #379 (ark-ff) Refactor Field implementation and PrimeField trait:
  • Switch from hardcoded FpXYZ to Fp<N> based on const generics.
  • Move Montgomery arithmetic to an optional backend.
  • Rename field_new macros to MontFp, QuadExt and CubicExt macros.
  • Introduce const fns for generating many constants.
  • Add default associated constants to reduce boilerplate.
  • Rename Fp*Parameters to Fp*Config.
  • Add From<u32>, From<u16>, and From<u8> impls for BigInt<N>.
