So, since the patch notes didn't seem to cover everything that was updated, I'm going to put what CS missed in here. Feel free to help out.
Updates to Character Creation:
You can now create up to 6 characters on one account (Previously limited to 3).
Updates to Temporal Rift System:
There are multiple rift crystals (Small ones) located throughout towns now. You can use any of these to access the new rift system, which looks like this:
Using this, you can now travel to different hotspots within the town itself, but to travel to another town, you'll still need to walk through the old rift.
Updates to all Partners:
Partners now have more voice acting (Try talking to any partner in town and notice how they have little phrases now).
Updates to Miroku:
Sell a new item called a "Star Fragment". Using one of these allows you to instantly access the rift by spawning a mini rift crystal in front of you.
Miroku now sells plenty of different defense magatama (The grey ones) if you have the appropriate friendship level.
Miroku now sell nearly every potion (HP and MP), including those from bargains (Given you have him at an appropriate friendship level).
Updates to Kaguya:
She's crafting some interesting things now...
Updates to cash shop:
Character renaming item added for 70 oc. It is recommended that players check if their wanted name is available before using the item. This can be done by attempting to create a new character with said name to check the availability.
A fourth ougi card is now avaliable:
Updates to Bazaar system:
Players can now access all stalls in the area at once. No more running around and checking every shop individually.
