Square Enix just released the patch notes of Final Fantasy XIV: A Realm Reborn’s update 3.15, that is currently being implemented via a maintenance.
The patch is still not available for download, but we get more details about the Anima Weapon quest, that will start by talking to Rowena in Idillyshire. The only requirement is the completion of the main scenario quest chain for the expansion Heavensward. Those who have a Zodiac Weapon Zeta can exchange it for items required to progress during a quest. The weapon will be lost, but you’ll still be able to purchase a replica to use for glamors (only if you had the weapon to begin with).
The Scholasticate story quest line has also been added, and will start at the Pillars, speaking to Mathye in X:6 Y:9.
You can read the patch notes here, coming with a healthy dose of minor changes and fixes.
