Version 4.1 added some extra content. Such as:

• A New Bonus Character. Lunalchemy's BV the Cupid!
• A Bonus Equipment section to the AG Equipment Collection Room.
• New UI flare for the Main Menu.
• Updated Signature Strike Active music.
• Updated functionality to the Dynamic Auto mode in the Visual Novel.
• General touch ups such as bug & glitches fixes, typo fixing and battle system rebalancing.
  

One odd part is that the Female Announcer will not be present for BV the Cupid's name call. She's currently unavailable to record.
