Thanks "nice2know_u" Change Log as translated by "IversonJack"
1. Support for 3.95~3.99 APE encoding added.
2. Fixed bug related to VBR MP3 files not displaying track times correctly.
3. Fixed bug related to when a VBR MP3 track finishes playing, and then goes on to play an APE file, the crash that happens.
4. Fixed bug related to when hovering in menus, pressing "enter" resulted in an option to close the player? (not quite sure about this one).
5. Fixed bug related to when after one manually close down the backlight, player unable to display screen again. (on M6, this is the function when you press and hold the menu button).
6. Fixed bug relating to crashing when voice record folder is opened.
7. Fixed bug that causes music to not be able to fast forward.
8. Fixed bug when a song is on pause, the "pupu" sound the player makes when you slide the volume up or down. (LOL).
9. Fixed bug when in "all music" folder, when you are at the bottom of the list, and you tap once more downwards to go to the top of the list, the crap stuff that is left at the bottom of the selector strip (LOL).
+1 thing i noticed: touchpad sensitivity has been increased! scrolling through menus is faster than before, i like it!
