Patch Available - JMS 3.18

They got the Colossus the Giant theme dungeon, Vellud in their Crimsonwood (instead of Gollux in GMS, I believe JMS still uses either their own Masteria, or KMS's), and some SAO stuff. There's an Aincrad dungeon mentioned in the SAO reward boxes, with a Normal and Premium versions.
They also got the skill changes GMS just got I believe.

It's basically the same patch GMS just got from what I can see, but instead of Dawnveil, they get SAO stuff.

Seems the bosses in the dungeon are The Gleam Eyes, The Skull Reaper, and The Fatal Scythe, with familiars available for each of them. The Gleam Eyes was the boss for floor 74 in the LN, The Skull Reaper was the boss for floor 75, and The Fatal Scythe was a hidden boss underneath the city, estimated to be around the level of the 90th floor bosses.

Familiars? Aw man... That's pretty nice. Overall, even though it looks like low level content, it's pretty nice still.
