The long awaited patch for Final Fantasy XI is out. It's referred to as "The June Version Update".
Expect new missions for the Wings of the Goddess storyline, further involving you and giving answers to questions previously eft unanswered. There's several new campaign elements such as additional medals and ranks, which is a great addition and should keep players quite busy.
There's many adjustments to battle-related elements such as merit points and jobs. If you enjoy chocobo raising, you can enjoy new content. Slaying Notorious Monsters might be more your cup of tea, if it is, you'll be pleased, since SquareSoft have added several new encounters.
There's much much more added to the world of Vana'diel and I suggest you read the whole patch notes.
