Changelog

v0.8.0

Implement Try and Increment when converting hash to scalar #128
Improves performance and security of conversion 🔥
Get rid of deprecated rust-crypto dependency #137
- Changed the crate providing merkle trees support: merkle-sha3 v0.1 → merkle-cbt v0.3
- Merkle trees API has been slightly changed
- Merkle trees are generic over hash function (it used to work with keccak256 only)
- Merkle proofs built by previous versions of curv are incompatible with latest curv
Make the commitments generic over the hash function #129
Allows the user to choose their own hash function when using our hash and related commitments
Unify and optimise bigint serialization #139
- Bigints are serialized as bytes (instead of converting to hex/decimal format), that should save communication size (depends on serialization backend)
- Different backends serialize bigints in the same way, ie. number serialized via rust-gmp backend will be properly deserialized via num-bigint backend and vice-versa
- Compatibility notes: bigints serialization format is changed, so numbers serialized with older curv are not compatible with the newest version

Fix point subtraction. Bug was introduced in v0.8.0-rc1. #127
Add Polynomial::lagrange_basis function #130
Katex <> Docs integration #131
Allows using KaTeX in documentation comments. Math formulas will be properly rendered on docs.rs.
LDEI proof minor improvements #133
Adds missing implementations of Clone and serialization traits.
Update hmac, digest, sha2,sha3 dependencies #134
hmac: v0.7.1 → v0.11
digest: v0.8.1 → v0.9
sha2: v0.8.0 → v0.9
sha3: v0.8.2 → v0.9

Elliptic curve API has been significantly changed #120

In particular: ECPoint, ECScalar traits were redesigned. They remain, but are not supposed to be used directly anymore. In replacement, we introduce structures Point, Scalar representing elliptic point and scalar. See curv::elliptic::curves module-level documentation to learn more.
Add low degree exponent interpolation proof #119
