## 1.0.0 - 2022-08-10
- Improved docs.
## 1.0.0-alpha.2 - 2022-07-28
- Change name of the `extern fn`s to avoid clash with critical-section 0.2.
## 1.0.0-alpha.1 - 2022-07-28
Breaking changes:
- Removed all builtin impls. These are going to be provided by platform-support crates now.
- Renamed `custom_impl!` to `set_impl!`.
- RestoreState is now an opaque struct for the user, and a transparent `RawRestoreState` type alias for impl writers.
- RestoreState type is now configurable with Cargo features. Default is `()`. (previously it was fixed to `u8`.)
- Added own `CriticalSection` and `Mutex` types, instead of reexporting them from `bare_metal`.
