### Fixed
- Fixed union length comparison. (#228)

## ~~[v0.10.0] - 2021-01-16~~

  `RawIntoIter`, and `RawParIter`. (#175)

- Added a `drain_filter` function to `HashSet`. (#179)

### Changed

## [v0.8.0] - 2020-06-18

### Fixed
- Marked `RawTable::par_iter` as `unsafe`. (#157)

### Changed
- Reduced the size of `HashMap`. (#159)
- No longer create tables with a capacity of 1 element. (#162)

- Pulled in `HashMap` changes from rust-lang/rust (#164):
  - `extend_one` support on nightly.
  - `CollectionAllocErr` renamed to `TryReserveError`.
  - Added `HashSet::get_or_insert_owned`.
  - `Default` for `HashSet` no longer requires `T: Eq + Hash` and `S: BuildHasher`.

### Added
- Added `or_insert_with_key` to `Entry`. (#152)

### Fixed
- Partially reverted `Clone` optimization which was unsound. (#154)

### Changed
- Disabled use of `const-random` by default, which prevented reproducible builds. (#155)

### Added
- Added `HashMap::get_key_value_mut`. (#145)

### Changed
- Optimized `Clone` implementation. (#146)
