0.6.0 (6/20/2015) - Added support for `EXT-X-MAP` tags, introduced `ByteRange` class to handled shared byterange parsing/serialization functionality. **Breaking changes**: SegmentItem now exposes a single byterange instance accessor rather than byterange_length and byterange_start, made all parse methods static for consistency (ex: MediaItem.parse).

***

0.5.3 (2/24/2015) - [stan3](https://github.com/stan3) fixed issue recently introduced in Reader where `EXT-X-STREAM-INF` missing resolution would break parsing.

***

0.5.1 (2/16/2015) - [takashisite](https://github.com/takashisite) added support for [EXT-X-DISCONTINUITY](https://tools.ietf.org/html/draft-pantos-http-live-streaming-14#section-4.3.2.3).

***

0.5.0 (2/10/2015) - **BREAKING**: renamed PlaylistItem.playlist to PlaylistItem.uri, MediaItem.group to MediaItem.group_id, and PlaylistItem.bitrate to PlaylistItem.bandwidth so attributes more closely match the spec.

***

0.4.0 (1/20/2015) - **BREAKING**: Playlist.audio is now Playlist.audio_codec, audio now represents the newly supported AUDIO attribute, please update your code accordingly. Added support for all `EXT-X-MEDIA` attributes as well as the following `EXT-X-STREAM-INF` attributes: `AVERAGE-BANDWIDTH`, `AUDIO`, `VIDEO`, `SUBTILES`, and `CLOSED-CAPTIONS`. This means the library now supports alternate audio / camera angles as well as subtitles and closed captions. The `EXT-X-PLAYLIST-TYPE` attribute is now supported as Playlist.type. [elsurudo](https://github.com/elsurudo) added support for comments/titles in SegmentItems. A bug was also fixed in Reader that prevented reuse of the instance.
***

***

0.3.0 (11/26/2014) - **DEPRECIATED** `add_playlist` and `add_segment` on `Playlist`, manipulate the items array directly instead. Extracted writing of playlists to it's own Writer class (only use directly if you want more control over the process). Added read convience method to Playlist so Reader doesn't have to be used directly unless more control is desired. Simplified validation and other aspects during this refactoring.

***

0.2.1 (11/26/2014) - Moved codec generation / validation to `PlaylistItem`, allowing for the flexibility to either specify `:audio`, `:level`, `:profile` when creating new instances (codecs value will be automatically generated) or just set the codecs attribute directly.

***

0.2.0 (11/25/2014) - Added ability to parse m3u8 playlists with new `Reader` class. Introduced two new classes to represent the items that make up a Playlist: `PlaylistItem` and `SegmentItem`.

***

0.1.3 (11/23/2014) - Fixed bug in codec string generation.
