## [0.2.0.1] - 2019-05-19

### Changed
- Swapped out `ghc-prim` and `primitive` for `vector`

## [0.2.0] - 2019-02-03

### Added
- `destroy` function, for reaping the background thread
- `recurring_` function

### Changed
- If the timer wheel reaper thread crashes, it will propagate the exception to
the thread that spawned it
- `new` may now throw `InvalidTimerWheelConfig`
- The cancel action returned by `register` is now memoized, which fixes a bug
involving trying to cancel a `recurring` timer twice. The second call used to
spin forever and peg a CPU
- Use `Config` type for creating a timer wheel
- Change argument order around
- Rename `new` to `create`
- Make recurring timers more accurate
