3.0.0 / 2015-04-22

Rebuild meta data parsing (breaking):
- the meta event has been removed, metadata is now provided as third argument to the exit listener
- metadata format changed to a more generic per stream structure, see readme.

2.0.0 / 2014-05-14

Change events (breaking):
- use .on('message', ...) instead of .on('data', ...)
- use .on('exit', ...) instead of .on('end', ...)
New event:
- .on('data', ...) - a buffer object with converted data (if outputting to pipe:1)
Add support for pipe:0 and pipe:1
Uses a duplex stream internally instead of a readable stream
