## [Unreleased]
## [0.3.1] - 2021-10-26

- `with_cryo` can now take `&[mut] (impl ?Sized)` (a reference to a dynamically-sized object)

## [0.3.0] - 2021-10-25

- Breaking (**soundness fix**):
    - `Cryo<T, _>: Send` requires `T: Sync` instead of `T: Send`.
    - `CryoMut<T, _>: Send` now requires `T: Sync` in addition to `T: Send`.
    - `CryoMutReadGuard<T, _>: Send` requires `T: Sync` instead of `T: Send`.
- Breaking: The `Send`/`Sync`-ness of `Lock` is now taken into account in trait bounds.
- `Cryo<T, _>: Sync` no longer requires `T: Send`.
- `CryoMutReadGuard<T, _>: Sync` no longer requires `T: Send`.
- `CryoMutWriteGuard<T, _>: Sync` if `T: Sync`.
- Breaking (**soundness fix**): Remove `cryo!`

## [0.2.7] - 2021-10-25

- Deprecate 0.2.x because of numerous soundness bugs that require breaking fixes

## [0.2.6] - 2021-09-11

- Update `README.md`

## [0.2.4] - 2021-09-11

- Bring `with_cryo` back with an overloaded interface (one function can produce both `Cryo` and `CryoMut` depending on a given type).
- Deprecate (**soundness fix**): `cryo!`

## [0.2.3] - 2021-09-02

- Breaking (**soundness fix**): `{Cryo, CryoMut}::new` is now `unsafe fn`.

## [0.2.2] - 2021-05-08

- `cryo` no longer enables the default features of `stable_deref_trait`, fixing builds on `core`-only targets.

## [0.2.1] - 2021-04-19

- Added `AtomicLock`

## [0.2.0] - 2021-04-18

- Breaking: `Cryo` is now generalized over lock implementations. Two implementations are provided: `LocalLock` (single-threaded) and `SyncLock` (borrows can be sent to other threads). You need to specify in `cryo!` to use the latter.
- Breaking: `parking-lot` feature was removed.
- Breaking: `Cryo` now utilizes `std::pin::Pin` (instead of making the constructor `unsafe fn`) for pinning. Most methods now take `self: Pin<&Cryo<_, _>>` as the receiver.
- Breaking: `with_cryo[_mut]` was superseded by `cryo!`.
- Breaking: `std` feature was added.
