#Changelog
## bliss 0.5.0
* Add `album_artist` and `duration` to `Song`.
* Fix a bug in `estimate_tuning` that led to empty chroma errors.
* Remove the unusued Library trait, and extract a few useful functions from
there (`analyze_paths`, `closest_to_album_group`.
there (`analyze_paths`, `closest_to_album_group`).
* Rename `distance` module to `playlist`.
* Remove all traces of the "analyse" word vs "analyze" to make the codebase
more coherent.
