What's New in Version 2.3.1
What's New in Fission 2.3.1:
* Major Enhancement: Fission now fully supports tabs on MacOS 10.12 (Sierra). Previous versions could crash when attempting to make new tabs, so be sure to update!
* Major Enhancement: We've made optimizations throughout the app to make this the snappiest Fission yet. Waveform generation is now 20% faster, and AAC saving has been sped up as well.
* Enhancement: Chapterized AAC and MP3 files now use the Album tag as the Title for the file.
* Enhancement: Fission will automatically set a default title based on any file's name, and set Artwork from a video file's preview frame.
* Enhancement: Save operations can now be cancelled if necessary.
* Bug Fix: AIFF/WAV limits are now checked before transcoding, so that malformed (overly long/large) AIFF and WAV files won't be created.
* Bug Fix: Compatibility with rare and poorly-formed AAC files has been improved.
* Bug Fix: Several small cosmetic improvements have been made, including fixes to the “Where” field, file name display in the Inspector, and the Comment field.
* Bug Fix: The “.m4b” and “.aif” extensions are now allowed by the Save panel.
