[Unreleased]
Changed
- MSRV is now 1.56.0.
- Migrated to
ff 0.12
,group 0.12
.
[0.3.1] - 2022-04-20
Added
gpu
feature flag, which exposes implementations of theGpuField
trait from theec-gpu
crate forpasta_curves::{Fp, Fq}
. This flag will eventually control all GPU functionality.repr-c
feature flag, which helps to facilitate usage of this crate's types across FFI by conditionally addingrepr(C)
attribute to point structures.pasta_curves::arithmetic::Coordinates::from_xy
Changed
pasta_curves::{Fp, Fq}
are now declared asrepr(transparent)
, to enable their use across FFI. They remain opaque structs in Rust code.
[0.3.0] - 2022-01-03
Added
- Support for
no-std
builds, via two new (default-enabled) feature flags:alloc
enables thepasta_curves::arithmetic::{CurveAffine, CurveExt}
traits, as well as implementations of traits likegroup::WnafGroup
.sqrt-table
depends onalloc
, and enables the large precomputed tables (stored on the heap) that speed up square root computation.
pasta_curves::arithmetic::SqrtRatio
trait, extendingff::PrimeField
with square roots of ratios. This trait is likely to be moved into theff
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
(useff::PrimeField::root_of_unity
instead).FieldExt::{T_MINUS1_OVER2, pow_by_t_minus1_over2, get_lower_32, sqrt_alt,
sqrt_ratio}
(moved toSqrtRatio
trait).FieldExt::{RESCUE_ALPHA, RESCUE_INVALPHA}
FieldExt::from_u64
(useFrom<u64> for ff::PrimeField
instead).FieldExt::{from_bytes, read, to_bytes, write}
(useff::PrimeField::{from_repr, to_repr}
instead).FieldExt::rand
(useff::Field::random
instead).CurveAffine::{read, write}
(usegroup::GroupEncoding::{from_bytes, to_bytes}
instead).
[0.2.1] - 2021-09-17
Changed
- The crate is now licensed as
MIT OR Apache-2.0
.
[0.2.0] - 2021-09-02
Changed
- Migrated to
ff 0.11
,group 0.11
.
[0.1.2] - 2021-08-06
Added
- Implementation of
group::WnafGroup
for Pallas and Vesta, enabling them to be used withgroup::Wnaf
for targeted performance improvements.
[0.1.1] - 2021-06-04
Added
- Implementations of
group::cofactor::{CofactorCurve, CofactorCurveAffine}
for Pallas and Vesta, enabling them to be used in cofactor-aware protocols that also want to leverage the affine point representation.
[0.1.0] - 2021-06-01
Initial release!
