## [Unreleased]
## [v0.11.2] - 2021-03-25
## Fixed
- Added missing allocator type parameter to `HashMap`'s and `HashSet`'s `Clone` impls. (#252)
## [v0.11.1] - 2021-03-20
## Fixed
- Added missing `pub` modifier to `BumpWrapper`. (#251)
## [v0.11.0] - 2021-03-14
## Added
- Added safe `try_insert_no_grow` method to `RawTable`. (#229)
- Added support for `bumpalo` as an allocator without the `nightly` feature. (#231)
- Implemented `Default` for `RawTable`. (#237)
- Added new safe methods `RawTable::get_each_mut`, `HashMap::get_each_mut`, and
`HashMap::get_each_key_value_mut`. (#239)
- Added `From<HashMap<T, ()>>` for `HashSet<T>`. (#235)
- Added `try_insert` method to `HashMap`. (#247)
## Changed
- The minimum Rust version has been bumped to 1.49.0. (#230)
- Significantly improved compilation times by reducing the amount of generated IR. (#205)
## Removed
- We no longer re-export the unstable allocator items from the standard library, nor the stable shims approximating the same. (#227)
- Removed hasher specialization support from `aHash`, which was resulting in inconsistent hashes being generated for a key. (#248)
## Fixed
- Fixed union length comparison. (#228)
## ~~[v0.10.0] - 2021-01-16~~
This release was _yanked_ due to inconsistent hashes being generated with the `nightly` feature. (#248)
## Changed
- Parametrized `RawTable`, `HashSet` and `HashMap` over an allocator. (#133)
- Improved branch prediction hints on stable. (#209)
- Optimized hashing of primitive types with AHash using specialization. (#207)
- Only instantiate `RawTable`'s reserve functions once per key-value. (#204)
## [v0.9.1] - 2020-09-28
## Added
- Added safe methods to `RawTable` (#202):
- `get`: `find` and `as_ref`
- `get_mut`: `find` and `as_mut`
- `insert_entry`: `insert` and `as_mut`
- `remove_entry`: `find` and `remove`

- Made `RawTable::drain` safe. (#201)
## [v0.9.0] - 2020-09-03
### Fixed
- `drain_filter` now removes and yields items that do match the predicate,
rather than items that don't. This is a **breaking change** to match the
behavior of the `drain_filter` methods in `std`. (#187)
### Added
- Added `replace_entry_with` to `OccupiedEntry`, and `and_replace_entry_with` to `Entry`. (#190)
- Implemented `FusedIterator` and `size_hint` for `DrainFilter`. (#188)
### Changed
- The minimum Rust version has been bumped to 1.36 (due to `crossbeam` dependency). (#193)
- Updated `ahash` dependency to 0.4. (#198)
- `HashMap::with_hasher` and `HashSet::with_hasher` are now `const fn`. (#195)
- Removed `T: Hash + Eq` and `S: BuildHasher` bounds on `HashSet::new`,
`with_capacity`, `with_hasher`, and `with_capacity_and_hasher`. (#185)
## [v0.8.2] - 2020-08-08
### Changed
- Avoid closures to improve compile times. (#183)
- Do not iterate to drop if empty. (#182)
## [v0.8.1] - 2020-07-16
### Added
- Added `erase` and `remove` to `RawTable`. (#171)
- Added `try_with_capacity` to `RawTable`. (#174)
- Added methods that allow re-using a `RawIter` for `RawDrain`,
`RawIntoIter`, and `RawParIter`. (#175)
- Added `reflect_remove` and `reflect_insert` to `RawIter`. (#175)
- Added a `drain_filter` function to `HashSet`. (#179)
### Changed
- Deprecated `RawTable::erase_no_drop` in favor of `erase` and `remove`. (#176)
- `insert_no_grow` is now exposed under the `"raw"` feature. (#180)
## [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)
- Removed `K: Eq + Hash` bounds on `retain`. (#163)
- 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`.
## [v0.7.2] - 2020-04-27
### 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)
- Optimized `repeat` function. (#150)
- Use `NonNull` for buckets, which improves codegen for iterators. (#148)
## [v0.7.1] - 2020-03-16
### Added
- Added `HashMap::get_key_value_mut`. (#145)
### Changed
- Optimized `Clone` implementation. (#146)
## [v0.7.0] - 2020-01-31
### Added
- Added a `drain_filter` function to `HashMap`. (#135)
### Changed
- Updated `ahash` dependency to 0.3. (#141)
- Optimized set union and intersection. (#130)
- `raw_entry` can now be used without requiring `S: BuildHasher`. (#123)
- `RawTable::bucket_index` can now be used under the `raw` feature. (#128)
## [v0.6.3] - 2019-10-31
### Added
- Added an `ahash-compile-time-rng` feature (enabled by default) which allows disabling the
`compile-time-rng` feature in `ahash` to work around a Cargo bug. (#125)
## [v0.6.2] - 2019-10-23
### Added
- Added an `inline-more` feature (enabled by default) which allows choosing a tradeoff between
runtime performance and compilation time. (#119)
## [v0.6.1] - 2019-10-04
### Added
- Added `Entry::insert` and `RawEntryMut::insert`. (#118)

## [v0.6.0] - 2019-08-13
### Fixed
- Fixed AHash accidentally depending on `std`. (#110)
### Changed
- The minimum Rust version has been bumped to 1.32 (due to `rand` dependency).
## ~~[v0.5.1] - 2019-08-04~~
This release was _yanked_ due to a breaking change for users of `no-default-features`.
### Added
- The experimental and unsafe `RawTable` API is available under the "raw" feature. (#108)
- Added entry-like methods for `HashSet`. (#98)
### Changed
- Changed the default hasher from FxHash to AHash. (#97)
