Oct 14, 2013
MacOS X Intel
Fission now offers full support for developer preview versions of Mac OS X 10.9 (Mavericks).
Fission is now a 64-bit application. That is literally twice as many bits as before. You probably won't notice much difference just yet, but this will enable performance gains in the future.
The QuickTime engine for opening file has been replaced with our own internal libav. Some extremely rare file formats may no longer be supported. Get in touch if you a format you use is missing.
Fission has an entirely new saving pipeline. Hopefully, you won't even notice, it will simply work. Oh, saving a ringtone from the Mac App Store version of Fission works a bit better, that's potentially noticeable.
Dragging a song from iTunes into the Mac App Store version of Fission should now work the first time. Previously, it only worked after two tries. Yes, really.
The License window has been overhauled, with HTML. Neat!
Chapters which contain multiple images now load images more logically (grabbing the first image in the chapter).

Fission v 2.1.2

MacOS X UB

Progress bars should now appear more reliably when exporting audio.
An issue where the Mac App Store version of Fission would fail to save to a previously-specified location is now fixed.

Fission is now better a reading in chapterized AAC files. It was already pretty great, to be sure, but now it's even better.
Several VoiceOver improvements have been made, with labels on previously unlabeled controls. We've still got more work to do, so watch for further updates, VoiceOver users!
A conflict with Many Tricks' window manager Moom, which caused the selection of split points to fail, has been handled.
Assorted rare crashes should now be even more rare, so rare that you might suspect they're gone entirely, which they are!
There are probably other improvements which we've forgotten. The best way to be sure you've got them is, of course, to update.
