The new update brings some changes:

This new version needs at least iOS 6.1! Do NOT update if you are still playing on iOS 5.x!

• language can be changed from the settings screen in the game (you have to restart the game afterwards)
• some language fixes for german
• music plays now during bard songs, you can adjust the volume in the settings screen
• game center activation is no longer available from within the game, you have to use your Settings App
• you can now switch between the normal manual and the compendium (if you bought it)

I already noticed that the music volume slider is not right aligned on the iPhone 5, this will be fixed with the next update.
