0.23.0 - 2022-06-21

The major change in this version is the increase of the Minimum Supported Rust Version (MSRV) from 1.29 to 1.41.1, this is a big change because it introduces Rust Edition 2018 to the codebase along with all the benefits that brings.

Breaking changes

• MSRV bumped to 1.41.1 and edition changed to 2018
• serde implements serialize fixed-width arrays as tuples in binary formats to avoid encoding the length
• Key tweaking methods renamed and refactored to use a more functional-style, they now accept a new Scalar type instead of raw slices
• Update rand dependency to 0.8
