What's New in Version 2.3.0
* MP3 Chapters: Fission now supports saving chapter marks in MP3 files, as well as editing existing chapterized MP3s. MP3 chapters are handy for podcasters in particular.
* Faster MP3 Encoding: Encoding of MP3s (used by the Export command) has been drastically sped up.
* Damage Visualization: When Fission loads a damaged file, it will now visually display bad packets in the waveform.
* A heaping handful of minor fixes and improvements have also been made, for improved file loading and handling as well as better performance overall.
