Okay so, several days ago part1 began:

1. Main quest half AP and increased exp. This happens all the time anyway, so nothing here.
2. Raid quest Missions for some free materials. This happens all the time anyway, so nothing here.
3. GO rewards increased, this will probably be in effect for the next two weeks (starting next Monday). It's not much.
4. Jewel login bonus. This happens all the time anyway, so nothing here.

Wow... that's... literally fucking nothing.
We also got a free 10-pull ticket from somewhere. I don't even know where it came from, but eh, I'll take it.

Part2 began yesterday:

5. Material caves all unlocked and AP halved. This happens all the time anyway, so nothing here... and it isn't even ingame yet? Maybe tomorrow?
6. Material caves Missions for some free materials. This happens all the time anyway, so nothing here... and it isn't even ingame yet? Maybe tomorrow?
7. There's supposed to be a Jewel login bonus, but it's most likely the same thing as #4.
8. Free 10-pull every day. This actually has its own gacha for once, so you don't need to go hunting for the right banner. And why did this begin before the other two part2 stuff...?
