## [Unreleased]

## [0.6.3]

### Added
- `Debug` and `Clone` on iterators (#37).

## [0.6.2]

### Added
- `BiBTreeMap::retain` (#30).
- `BiHashMap::reserve`, `BiHashMap::shrink_to`, and `BiHashMap::shrink_to_fit` (#32).

## [0.6.1]

### Added
- `serde` trait implementations for `BiHashMap` are now generic over the left
and right hashers (#27, #28). Before, they were only implemented for the
default hasher.

## [0.6.0]

### Changed
- Generalize query interfaces using `std::borrow::Borrow` for `BiMap` methods
like `get`, `contains`, and `remove`. This more closely aligns to the API
provided by the Rust standard library.

## [0.5.3]

### Added
- Implement `Hash` for `BiBTreeMap` (#23).

### Changed
- Minor edits to the README.

### Removed
- Unnecessary trait bounds on the `fmt::Debug` impl for `BiMap<L, R>` (#22).

## [0.5.2]

### Added
- Documentation link to docs.rs in Cargo.toml.

## [0.5.1]

### Fixed
- Outdated docs.rs link in README.

## [0.5.0]

### Added
- This changelog.
- `Extend` implementations.
- Pretty `Debug` formatting.
- `left_range` and `right_range` methods for `BiBTreeMap`.

### Changed
- Documentation and useful public documents were created and/or updated.

### Fixed
- Tests for `BiBTreeMap` run correctly with `no_std`.

## [0.4.0]
