+# 0.2.0
+
+This release adds implementations of the `ff`, `group`, and `pairing` traits (with the
+latter two being gated by the `groups` and `pairings` feature flags respectively).
+Additional trait implementations (for standard traits) have been added where the `ff`,
+`group`, and `pairing` trait bounds require them.
+
+## Added
+* `bls12_381::Bls12`, a `pairing::Engine` for BLS12-381 pairing operations. It implements
+  the following traits:
+  * `pairing::{Engine, MultiMillerLoop}`
+* New trait implementations for `bls12_381::G1Projective`:
+  * `group::{Curve, Group, GroupEncoding, WnafGroup}`
+  * `group::prime::{PrimeCurve, PrimeGroup}`
+* New trait implementations for `bls12_381::G1Affine`:
+  * `group::{GroupEncoding, UncompressedEncoding}`
+  * `group::prime::PrimeCurveAffine`
+  * `pairing::PairingCurveAffine`
+* New trait implementations for `bls12_381::G2Projective`:
+  * `group::{Curve, Group, GroupEncoding, WnafGroup}`
+  * `group::prime::{PrimeCurve, PrimeGroup}`
+* New trait implementations for `bls12_381::G2Affine`:
+  * `group::{GroupEncoding, UncompressedEncoding}`
+  * `group::prime::PrimeCurveAffine`
+  * `pairing::PairingCurveAffine`
+* New trait implementations for `bls12_381::Gt`:
+  * `group::Group`
+* New trait implementations for `bls12_381::MillerLoopResult`:
+  * `pairing::MillerLoopResult`
+* New trait implementations for `bls12_381::Scalar`:
+  * `ff::{Field, PrimeField}`
+
 # 0.1.1
 
 Added `clear_cofactor` methods to `G1Projective` and `G2Projective`. If the crate feature `endo`
