## Unreleased

### Added

### Changed

### Fixed

## v1.2.0 - 2023-12-06

### Changed

- Docs: Add sanity check to `half_period_counter` code example
- Deprecate `Monotonic::should_dequeue_check` as it was erroneous

### Fixed

- Fix race condition in `half_period_counter::calculate_now`.
  This sadly required a minor API change.

## v1.1.0 - 2023-12-04

### Added

- `half_period_counter` containing utilities for implementing a half-period-counter based monotonic.
- `should_dequeue_check` to the `Monotonic` trait to handle bugged timers.

### Changed

### Fixed

- **Soundness fix:** `TimerQueue` did not wait long enough in `Duration` based delays. Fixing this sadly required adding a `const TICK_PERIOD` to the `Monotonic` trait, which requires updating all existing implementations.
- If the queue was non-empty and a new instant was added that was earlier than `head`, then the queue would no pend the monotonic handler. This would cause the new `head` to be dequeued at the wrong time.

## v1.0.0 - 2023-05-31
