Due to a fairly serious bug introduced in 2.1.4, here's 2.1.5. Everyone is advised to update to it.
- Fixed a bug in audio display that caused it not to update properly (introduced on 2.1.4)
- Fixed a bug that caused Aegisub to crash if you attempted to load any ASS subtitles with malformed embedded fonts
- Tweaked the layout of the visual typesetting bar
BTW, a good way to keep up with Aegisub updates it to subscribe to the Atom feed - I recommend Google Reader.
