- Fix the album art in audio file.
- Fix display issues when changing window size.
- Fix window does not disappear when finishing the playback in OS X 10.11 El Capitan.
- Fix pixelation in OS X 10.11 El Capitan.
- Add hidden setting: AsyncMode.
- Change the app icon.
- several trivial issues in OS X 10.11 El Capitan.
- [Known Issue] MPlayerX now does not work well when entering/exiting full-screen in El Capitan by dragging the window in Mission Control. It is because full-screen behavior changed so much between OS X 10.6 and 10.11. Now I am trying to figure out a way to fix it without breaking backward-compatibility, but at worst, it is possible that MPX will drop OS X 10.7 and 10.8 support with the next release.
