## [Unreleased]

## [0.5.7] - 2022-08-15
### Changed
- Simplify file size retrieving code.
  [@saethlin](https://github.com/saethlin)

## [0.5.6] - 2022-08-11
### Added
- Memory locking and unlocking. See `Mmap::lock`, `Mmap::unlock`,
  `MmapMut::lock` and `MmapMut::unlock`.
  [@vmx](https://github.com/vmx)

## [0.5.5] - 2022-07-09
### Fixed
- Limit mapping length to `isize::MAX` to prevent undefined behavior
  on calling `std::slice::from_raw_parts`. Technically affects only 32-bit systems.
  [@adamreichold](https://github.com/adamreichold)

## [0.5.4] - 2022-06-04
### Added
- Add madvice operations specific to Darwin. [@turbocool3r](https://github.com/turbocool3r)
- Implement common traits for the `Advice` enum. [@nyurik](https://github.com/nyurik)

### Changed
- Make stub implementation Infallible. [@coolreader18](https://github.com/coolreader18)
- Use `tempfile` crate instead of `tempdir` in tests.
  [@alexanderkjall](https://github.com/alexanderkjall)

## [0.5.3] - 2022-02-10
### Added
- `Mmap::advise` and `MmapMut::advise`. [@nyurik](https://github.com/nyurik)

## [0.5.2] - 2022-01-10
### Added
- `flush`, `flush_async`, `flush_range` and `flush_async_range` to `MmapRaw` matching
  the corresponding methods on `MmapMut`.
  [@cberner](https://github.com/cberner)

## [0.5.1] - 2022-01-09
### Fixed
- Explicitly call `fstat64` on Linux, emscripten and l4re targets.
  [@adamreichold](https://github.com/adamreichold)

## [0.5.0] - 2021-09-19
### Added
- `MmapOptions` accepts any type that supports `RawHandle`/`RawFd` returning now.
  This allows using `memmap2` not only with Rust std types, but also with
  [async-std](https://github.com/async-rs/async-std) one.
  [@adamreichold](https://github.com/adamreichold)
- (unix) Memoize page size to avoid repeatedly calling into sysconf machinery.
  [@adamreichold](https://github.com/adamreichold)

### Changed
- (win) Use `std::os::windows::io::AsRawHandle` directly, without relying on `std::fs::File`.
  [@adamreichold](https://github.com/adamreichold)
- Do not panic when failing to release resources in Drop impls.
  [@adamreichold](https://github.com/adamreichold)

## [0.4.0] - 2021-09-16
### Added
- Optional [`StableDeref`](https://github.com/storyyeller/stable_deref_trait) support.
  [@SimonSapin](https://github.com/SimonSapin)

### Changed
- Mapping of zero-sized files is no longer an error.
  [@SimonSapin](https://github.com/SimonSapin)
- MSRV changed from 1.31 to 1.36

## [0.3.1] - 2021-08-15
### Fixed
- Integer overflow during file length calculation on 32bit targets.
- Stub implementation. [@Mrmaxmeier](https://github.com/Mrmaxmeier)

## [0.3.0] - 2021-06-10
### Changed
- `MmapOptions` allows mapping using Unix descriptors and not only `std::fs::File` now.
  [@mripard](https://github.com/mripard)

## [0.2.3] - 2021-05-24
### Added
- Allow compilation on unsupported platforms.
  The code will panic on access just like in `std`.
  [@jcaesar](https://github.com/jcaesar)

## [0.2.2] - 2021-04-03
### Added
- `MmapOptions::populate`. [@adamreichold](https://github.com/adamreichold)

### Fixed
- Fix alignment computation for `flush_async` to match `flush`.
  [@adamreichold](https://github.com/adamreichold)

## [0.2.1] - 2021-02-08
### Added
- `MmapOptions::map_raw` and `MmapRaw`. [@diwic](https://github.com/diwic)

## [0.2.0] - 2020-12-19
### Changed
- MSRV is 1.31 now (edition 2018).
- Make anonymous memory maps private by default on unix. [@CensoredUsername](https://github.com/CensoredUsername)
- Add `map_copy_read_only`. [@zseri](https://github.com/zseri)

## 0.1.0 - 2020-01-18
### Added
- Fork [memmap-rs](https://github.com/danburkert/memmap-rs).

### Changed
- Use `LICENSE-APACHE` instead of `README.md` for some tests since it's immutable.

### Removed
- `winapi` dependency. [memmap-rs/pull/89](https://github.com/danburkert/memmap-rs/pull/89)
