Japan servers have been updated to Armonia Final Episode. Van (v23.70.38) doesn't seem to be available yet, so this update should be v23.63.43. However, it does not seem to have the new ranking of missions as well as the dreadful weapon enhancement and enchantment transfer... I don't know if they just aren't implemented yet, or if Japan simply has no intention of implementing them.
UI Skin & Sound Files
The default UI skin has been updated, specifically button.bmp, hotkey.bmp, ping.bmp, and transfer.bmp files. I will update the existing skin packs on this site soon. The sound file will also be posted soon, along with the latest Imperial Wheel release.
