+`bellman` uses the `ff` and `group` crates to build circuits generically over a
+scalar field type, which is used as the "word" of a circuit. Arithmetic
+operations modulo the scalar field's prime are efficient, while other operations
+(such as boolean logic) are implemented using these words.

 ## Roadmap
 
-`bellman` is being refactored into a generic proving library. Currently it is
-pairing-specific, and different types of proving systems need to be implemented
-as sub-modules. After the refactor, `bellman` will be generic using the `ff` and
-`group` crates, while specific proving systems will be separate crates that pull
-in the dependencies they require.
+Currently `bellman` bundles an implementation of the Groth16 proving system.
+This will be moved into a separate crate in the future, and `bellman` will
+contain any utilities that make implementing proving systems easier.

+# 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::prime::PrimeCurveAffine`
+  * `pairing::PairingCurveAffine`
+* New trait implementations for `bls12_381::Gt`:

+  * `pairing::MillerLoopResult`
+* New trait implementations for `bls12_381::Scalar`:

+* The benchmarks are now implemented using `criterion`.
