Korean servers updated to The Symphonia Episode 2 on Feb 23, 2016. Similarly, Japan servers updated to the same patch on Mar 23, 2016.
I haven't been online in-game lately... and I wasn't checking the websites either so this came kind of late. I'm not really motivated to translate stuffs either, so if you want the quest guides or patch notes, check the links below for non-English versions.
