* **Breaking change:** FFprobe API changes to return `{:ok, term}` or `{:error, atom}` from `format_names/1`, `format/1`, `streams/1`.

## 0.5.0 (2018-03-26)
* **Breaking change:** Changed output format of `FFprobe.format/1` to be cleaner, based on ffmpeg JSON output.
Specifically: `"nb_programs"`, `"nb_streams"`, and `"probe_score"` now contain integers instead of binaries;
and tags are stored in a `"tags"` sub-map instead of being individual entries prefixed with "TAG:".
