0.11.0 (2021-09-06)

General

• All dependencies to use the digest 0.9 traits and APIs.

Clients of this generally only need to update the result method to finalize; and obviously make use of the v0.9 digest::Digest trait where necessary.

As a result, the deprecated k12, sha3 and Blake3 objects have been removed. Methods and functins that need a hasher are all generic over Digest.

We retain the convenience wrapper over VarBlake2B to produce 256 bit hashes and implement the necessary sub-traits to support digest::Digest.

Bug Fixes

• remove extra compress call during pubkey::deserialize (#56) (8864b5a2)

0.10.0 (2021-07-05)

• Support stable rust

Updated dependencies such that Rust stable 1.53 is now supported. The optimised avx_2 option will NOT rust on stable because there's still an unstable feature on subtle-ng. BUT this feature is actually for doc generation and has been removed from Rust. As soon as subtle-ng merges dalek-cryptography/subtle#85, avx2 will probably be supported on stable as well.

0.2.0 (2020-02-07)

General

• WASM and crate version now match. Eliminate that confusion.

WASM module

• Breaking change: KeyRing.sign doesn't take a nonce any more. It's not needed, and why risk someone re-using it?
• New method: key_utils.sign to sign keys not in the key ring
• New module: Commitments
