The preliminary notes are out so far, and doesn't have the PLD Job changes I wanted to check out most. There are however the UI changes mentioned in the LL (such as the new UI theme, Retainer+Glamour/Dye changes, easier DD item appraisal), details about new CC features, ARR dungeons for Explorer Mode, more gender-specific gear getting unlocked, and surprisingly more /cpose for /sit and while holding an umbrella.

There's more changes than that, and you can check them all out on the links below:
