## [3.0.0] - 2023-01-26

- **Breaking:** moved ronomon FastCDC implementation into `ronomon` module.
  What was `fastcdc::FastCDC::new()` is now `fastcdc::ronomon::FastCDC::new()`.
- flokli: remove `mut` from `&self` in `cut()` as it does not need to be mutable.
### Added
- Canonical implementation of FastCDC from 2016 paper in `v2016` module.
- Canonical implementation of FastCDC from 2020 paper in `v2020` module.
- `Normalization` enum to set the normalized chunking for `v2016` and `v2020` chunkers.
- `StreamCDC`, streaming version of `FastCDC`, in `v2016` and `v2020` modules.

## [2.0.0] - 2023-01-14

## [1.0.8] - 2023-01-12

### Added
- dristic: expose hash on chunk struct.

## [1.0.6] - 2021-01-08

- maobaolong: fixed logic for ceiling division function; results of
  chunking remain unchanged, so no visible difference.

## [1.0.1] - 2019-02-08
