+# Changelog
+
+## Unreleased
+
+- 
+
+## 1.19.0
+
+- Use `portable-atomic` instead of `atomic-polyfill`, [#251](https://github.com/matklad/once_cell/pull/251).
+
+## 1.18.0
+
+- `MSRV` is updated to 1.60.0 to take advantage of `dep:` syntax for cargo features,
+  removing "implementation details" from publicly visible surface.
+
+## 1.17.2
+
+- Avoid unnecessary synchronization in `Lazy::{force,deref}_mut()`, [#231](https://github.com/matklad/once_cell/pull/231).
+
+## 1.17.1
+
+- Make `OnceRef` implementation compliant with [strict provenance](https://github.com/rust-lang/rust/issues/95228).
+
+## 1.17.0
+
+- Add `race::OnceRef` for storing a `&'a T`.
+
+## 1.16.0
+
+- Add `no_std` implementation based on `critical-section`,
+  [#195](https://github.com/matklad/once_cell/pull/195).
+- Deprecate `atomic-polyfill` feature (use the new `critical-section` instead)
+
+## 1.15.0
+
+- Increase minimal supported Rust version to 1.56.0.
+- Implement `UnwindSafe` even if the `std` feature is disabled.
+
+## 1.14.0
+
+- Add extension to `unsync` and `sync` `Lazy` mut API:
+  - `force_mut`
+  - `get_mut`
+
+
+## 1.13.1
+
+- Make implementation compliant with [strict provenance](https://github.com/rust-lang/rust/issues/95228).
+- Upgrade `atomic-polyfill` to `1.0`
+
+## 1.13.0
+
+- Add `Lazy::get`, similar to `OnceCell::get`.
+
+## 1.12.1
+
+- Remove incorrect `debug_assert`.
+
+## 1.12.0
+
+- Add `OnceCell::wait`, a blocking variant of `get`.
+
+## 1.11.0
+
+- Add `OnceCell::with_value` to create initialized `OnceCell` in `const` context.
+- Improve `Clone` implementation for `OnceCell`.
+- Rewrite `parking_lot` version on top of `parking_lot_core`, for even smaller cells!
+
+## 1.10.0
+
+- upgrade `parking_lot` to `0.12.0` (note that this bumps MSRV with `parking_lot` feature enabled to `1.49.0`).
+
+## 1.9.0
+
+- Added an `atomic-polyfill` optional dependency to compile `race` on platforms without atomics
+
+## 1.8.0
+
+- Add `try_insert` API -- a version of `set` that returns a reference.
+
+## 1.7.2
+
+- Improve code size when using parking_lot feature.
+
+## 1.7.1
+
+- Fix `race::OnceBox<T>` to also impl `Default` even if `T` doesn't impl `Default`.
+
+## 1.7.0
+
+- Hide the `race` module behind (default) `race` feature.
+  Turns out that adding `race` by default was a breaking change on some platforms without atomics.
+  In this release, we make the module opt-out.
+  Technically, this is a breaking change for those who use `race` with `no_default_features`.
+  Given that the `race` module itself only several days old, the breakage is deemed acceptable.
+
+## 1.6.0
+
+- Add `Lazy::into_value`
+- Stabilize `once_cell::race` module for "first one wins" no_std-compatible initialization flavor.
+- Migrate from deprecated `compare_and_swap` to `compare_exchange`.
+
+## 1.5.2
+
+- `OnceBox` API uses `Box<T>`.
+  This a breaking change to unstable API.
+
+## 1.5.1
+
+- MSRV is increased to `1.36.0`.
+- document `once_cell::race` module.
+- introduce `alloc` feature for `OnceBox`.
+- fix `OnceBox::set`.
+
+## 1.5.0
+
+- add new `once_cell::race` module for "first one wins" no_std-compatible initialization flavor.
+  The API is provisional, subject to change and is gated by the `unstable` cargo feature.
+
+## 1.4.1
+
+- upgrade `parking_lot` to `0.11.0`
+- make `sync::OnceCell<T>` pass https://doc.rust-lang.org/nomicon/dropck.html#an-escape-hatch[dropck] with `parking_lot` feature enabled.
+  This fixes a (minor) semver-incompatible changed introduced in `1.4.0`
+
+## 1.4.0
+
+- upgrade `parking_lot` to `0.10` (note that this bumps MSRV with `parking_lot` feature enabled to `1.36.0`).
+- add `OnceCell::take`.
+- upgrade crossbeam utils (private dependency) to `0.7`.
+
+## 1.3.1
+
+- remove unnecessary `F: fmt::Debug` bound from `impl fmt::Debug for Lazy<T, F>`.
+
+## 1.3.0
+
+- `Lazy<T>` now implements `DerefMut`.
+- update implementation according to the latest changes in `std`.
+
+## 1.2.0
+
+- add `sync::OnceCell::get_unchecked`.
+
+## 1.1.0
+
+- implement `Default` for `Lazy`: it creates an empty `Lazy<T>` which is initialized with `T::default` on first access.
+- add `OnceCell::get_mut`.
+
+## 1.0.2
+
+- actually add `#![no_std]` attribute if std feature is not enabled.
+
+## 1.0.1
+
+- fix unsoundness in `Lazy<T>` if the initializing function panics. Thanks [@xfix](https://github.com/xfix)!
+- implement `RefUnwindSafe` for `Lazy`.
+- share more code between `std` and `parking_lot` implementations.
+- add F.A.Q section to the docs.
+
+## 1.0.0
+
+- remove `parking_lot` from the list of default features.
+- add `std` default feature. Without `std`, only `unsync` module is supported.
+- implement `Eq` for `OnceCell`.
+- fix wrong `Sync` bound on `sync::Lazy`.
+- run the whole test suite with miri.
+
+## 0.2.7
+
+- New implementation of `sync::OnceCell` if `parking_lot` feature is disabled.
+  It now employs a hand-rolled variant of `std::sync::Once`.
+- `sync::OnceCell::get_or_try_init` works without `parking_lot` as well!
+- document the effects of `parking_lot` feature: same performance but smaller types.
+
+## 0.2.6
+
+- Updated `Lazy`'s `Deref` impl to requires only `FnOnce` instead of `Fn`
+
+## 0.2.5
+
+- `Lazy` requires only `FnOnce` instead of `Fn`
+
+## 0.2.4
+
+- nicer `fmt::Debug` implementation
+
+## 0.2.3
+
+- update `parking_lot` to `0.9.0`
+- fix stacked borrows violation in `unsync::OnceCell::get`
+- implement `Clone` for `sync::OnceCell<T> where T: Clone`
+
+## 0.2.2
+
+- add `OnceCell::into_inner` which consumes a cell and returns an option
+
+## 0.2.1
+
+- implement `sync::OnceCell::get_or_try_init` if `parking_lot` feature is enabled
+- switch internal `unsafe` implementation of `sync::OnceCell` from `Once` to `Mutex`
+- `sync::OnceCell::get_or_init` is twice as fast if cell is already initialized
+- implement `std::panic::RefUnwindSafe` and `std::panic::UnwindSafe` for `OnceCell`
+- better document behavior around panics
+
+## 0.2.0
+
+- MSRV is now 1.31.1
+- `Lazy::new` and `OnceCell::new` are now const-fns
+- `unsync_lazy` and `sync_lazy` macros are removed
+
+## 0.1.8
+
+- update crossbeam-utils to 0.6
+- enable bors-ng
+
+## 0.1.7
+
+- cells implement `PartialEq` and `From`
+- MSRV is down to 1.24.1
+- update `parking_lot` to `0.7.1`
+
+## 0.1.6
+
+- `unsync::OnceCell<T>` is `Clone` if `T` is `Clone`.
+
+## 0.1.5
+
+- No changelog until this point :(
