## 0.0.4 - 2021-03-17

### Fixed

- Software is no_std now.

### Changed

- VOC index algorithm is using Fixed-point math now to make it closer to the original and enable quick no_std implementation. The new implementation should also be a bit more accurate but time will tell.


## 0.0.3 - 2021-03-12

### Fixed

- Concat removed to get the software to compile for no-std.


## 0.0.2 - 2021-03-11

### Changed
