What's New in Fission 2.4.3:
Critical Bug Fix: A hang which could occur when adding files together in Fission has been corrected.
Enhancement: Improved bitrate calculations now enable improved joining of some AAC compressed files, for better audio quality.
Bug Fix: To workaround a QuickLook and QuickTime Player bug which could prevent chapterized files from playing as expected, Fission now converts progressive JPEG images to baseline JPEG.
Bug Fix: The “Select Previous Clip” and “Select Next Clip” buttons now display properly, with no ironic clipping of the text itself.
Bug Fix: Ringtone saving no longer incorrectly overwrites an existing ringtone when saving a second time with the same name.
