- [SEMVER_MINOR] Add support for UTF-8 strings (https://github.com/shssoichiro/zxcvbn-rs/issues/4)
- [SEMVER_MAJOR] Remove the `ZxcvbnError::NonAsciiPassword` variant, since this error can no longer occur

- [SEMVER_MAJOR] Refactor `Match` to use an enum internally, to avoid cluttering the struct with several `Option` types (https://github.com/shssoichiro/zxcvbn-rs/issues/19)
- Make `Match` public (https://github.com/shssoichiro/zxcvbn-rs/issues/17)

- Refactor handling of strings to use streaming of characters. This brings zxcvbn closer to working on UTF-8 inputs.
- Fix an issue that would cause bruteforce scores to be too low (https://github.com/shssoichiro/zxcvbn-rs/issues/15)

- Upgrade dependencies and fix linter warnings

- Upgrade `derive_builder` to 0.5.0
- Fix a bug that was causing incorrect scoring for some passwords (https://github.com/shssoichiro/zxcvbn-rs/issues/13)

- [SEMVER_MAJOR] Change the signature for `zxcvbn` to take `&[]` instead of `Option<&[]>` for `user_inputs` (https://github.com/shssoichiro/zxcvbn-rs/issues/9)
- [SEMVER_MAJOR] Change the signature for `zxcvbn` to return `Result<Entropy, ZxcvbnError>` instead of `Option<Entropy>` (https://github.com/shssoichiro/zxcvbn-rs/issues/11)
