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

[Unreleased]

Added

• pasta_curves::arithmetic::SqrtRatio trait, extending ff::PrimeField with square roots of ratios. This trait is likely to be moved into the ff crate in a future release (once we're satisfied with it).

Removed

• pasta_curves::arithmetic:
  • Field re-export (pasta_curves::group::ff::Field is equivalent).
  • FieldExt::ROOT_OF_UNITY (use ff::PrimeField::root_of_unity instead).
  • FieldExt::{T_MINUS1_OVER2, pow_by_t_minus1_over2, sqrt_alt, sqrt_ratio} (moved to SqrtRatio trait).
  • FieldExt::{RESCUE_ALPHA, RESCUE_INVALPHA}

[0.2.1] - 2021-09-17

[0.1.1] - 2021-06-04

Added
