| ## [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) |

| |
| ## [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` |

| |
| ## [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) |

| |
| ### 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) |

| `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) |

| ## [v0.6.3] - 2019-10-31 |
| |
| ### Added |
| - Added an `ahash-compile-time-rng` feature (enabled by default) which allows disabling the |

| |
| ## [v0.6.2] - 2019-10-23 |
| |

| runtime performance and compilation time. (#119) |
| |
| ## [v0.6.1] - 2019-10-04 |
| |
| ### Added |
| - Added `Entry::insert` and `RawEntryMut::insert`. (#118) |
