## [Unreleased]

## [0.6.0] - 2023-12-29

### Changed
- Minimum Supported Rust Version: 1.75
- `zeroed` is now `const`.

## [0.5.0] - 2023-07-29

### Changed
- Minimum Supported Rust Version: 1.71
- `assume_init_read` is now `const`.

## [0.4.0] - 2023-05-07

### Removed
- `AssumeInitExt`, `SafeAssumeInitExt`, and `UninitExt`.
- The `prelude` module.

## [0.3.0] - 2023-04-18

### Added
- The `assume_init` module, featuring the `AssumeInit` trait.
- The `safe_assume_init` module, featuring the `SafeAssumeInit` trait.
- The `uninit` module, featuring the `Uninit` trait.
- The `AssumeInitExt`, `SafeAssumeInitExt`, and `UninitExt` traits.
- The `prelude` module.
- `Uninit` implementations for tuples of arity 1-12.
- A `nightly` feature flag that makes many functions `const`, requiring the nightly toolchain.
- The following functions:
  - `?const fn safe_assume_init`
  - `?const fn safe_assume_init_ref`
  - `?const fn safe_assume_init_mut`
- `const` to the following functions when the `nightly` feature flag is enabled:
  - `?const fn zeroed`
  - `?const fn new`
  - `?const fn write`
  - `?const fn as_mut_ptr`
  - `?const unsafe fn assume_init`
  - `?const unsafe fn assume_init_ref`
  - `?const unsafe fn assume_init_mut`
  - `?const unsafe fn assume_init_read`

### Changed
- Refactored `MaybeUninitExt` into `AssumeInit` and `Uninit`.
- Changed the trait bound of each function from `MaybeUninitExt` to either `AssumeInit` or `Uninit`, depending on which it requires.
- Moved each function to the module that corresponds with its new trait bound.
- `write` no longer drops the old value.

### Removed
- The `MaybeUninitExt` trait.
- Functions re-exported at the crate level.

## [0.2.0] - 2023-04-08

  - `fn as_mut_ptr`
  - `unsafe fn assume_init_read`
  - `unsafe fn assume_init_drop`
  - `fn write`

### Changed
- `assume_init_ref` is now `const`.
- `uninit` now has `#[must_use]`.

## [0.1.0] - 2023-04-07

### Added
- The following functions:
  - `const fn uninit`
  - `unsafe fn assume_init`
  - `unsafe fn assume_init_ref`
  - `unsafe fn assume_init_mut`
- The `MaybeUninitExt` trait.
- The following `MaybeUninitExt` implementations:
  - `MaybeUninit<T>`
  - `()`
  - `[T; N]` where `T: MaybeUninitExt`
  - `PhantomData<T>` where `T: ?Sized`
  - `PhantomPinned`
  - `Cell<T>` where `T: MaybeUninitExt`
  - `UnsafeCell<T>` where `T: MaybeUninitExt`
  - `ManuallyDrop<T>` where `T: MaybeUninitExt`
