### Fixed
|
|

|
|
|
### Changed
|
|

|
|

|
|
`with_capacity`, `with_hasher`, and `with_capacity_and_hasher`. (#185)
|
|
|
|
## [v0.8.2] - 2020-08-08

|
- Added `try_with_capacity` to `RawTable`. (#174)
|
|

|
|
`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

|
|

|
|
- Pulled in `HashMap` changes from rust-lang/rust (#164):
|
|
- `extend_one` support on nightly.
|
|
- `CollectionAllocErr` renamed to `TryReserveError`.
|
|
- Added `HashSet::get_or_insert_owned`.
|
|
